Discover how shared battery storage, rooftop solar and community energy solutions could help Australian apartment buildings reduce electricity costs and make better use of renewable energy.

Living in an apartment doesn’t necessarily mean missing out on the benefits of battery storage.

Across Australia, apartment owners, strata committees and property managers are looking for practical ways to improve energy efficiency, manage electricity costs and make their buildings more sustainable. However, installing a battery in an apartment building can be more complex than installing one in a standalone home.

Shared rooftops, separate electricity meters, limited installation space and strata approval requirements all need to be considered.

The good news is that you may not need an individual battery inside your apartment to benefit from energy storage.

Depending on your building’s electricity infrastructure, energy consumption and ownership arrangements, a shared battery system, rooftop solar and battery upgrade, or community energy arrangement may offer a practical alternative.

At EcoBridge, we believe the right energy solution starts with understanding your building’s needs, available opportunities and long-term objectives.

In this guide, we explore how apartment communities can approach battery storage, what to consider before investing, and how to determine whether your property could be suitable.

Why Are Apartment Buildings Exploring Battery Storage?

Apartment buildings often consume electricity throughout the day and night. Lifts, hallway lighting, ventilation, car parks, security systems and shared facilities can all contribute to ongoing common-area electricity expenses.

At the same time, suitable rooftops may provide valuable space for solar panels to generate electricity during daylight hours.

Without effective energy management or battery storage, some solar generation may be exported to the electricity grid instead of being used later when the building needs it.

A suitably designed battery system can store some of that energy for use at another time.

Depending on the building and system design, this could help:

• Reduce electricity purchased for common areas.
• Increase the use of rooftop solar energy within the building.
• Manage certain periods of peak electricity demand.
• Support backup power for selected essential circuits when the system is specifically designed and configured for backup operation.
• Improve the building’s long-term energy infrastructure.
• Support sustainability initiatives and more informed energy planning.

The potential benefits depend on factors such as electricity consumption, solar generation, tariffs, installation costs, battery capacity and how the stored electricity is used.

For strata committees and property managers, the opportunity is to identify an energy solution that delivers measurable value rather than simply installing equipment.

Three Ways Apartment Communities Could Benefit From Battery Storage

1. Shared battery storage for common areas

One option is to install a central battery system designed to support eligible building electricity loads.

For example, an apartment building with rooftop solar could store excess daytime solar generation and use some of that energy later for common-area electricity consumption.

This may be worth investigating in buildings with significant shared electricity requirements, including lifts, car park lighting, ventilation systems and communal facilities.

Instead of installing individual batteries in every apartment, the owners corporation can explore whether a shared system could help manage the building’s collective energy costs.

However, a shared battery serving common areas will not automatically reduce residents’ individual electricity bills. The system must be designed around the intended loads, metering arrangements and ownership structure.

2. Integrated solar and battery systems for multiple apartments

Some apartment buildings may be suitable for a more comprehensive energy system combining rooftop solar, battery storage and technology to distribute electricity benefits among participating apartments.

This approach can be more complex because individual apartments frequently have separate electricity meters and retail electricity arrangements.

Depending on the building, the project may require additional metering, electrical infrastructure, an embedded network or another suitable electricity-sharing arrangement.

Before proceeding, the building should establish:

• Which apartments or common property areas can benefit.
• How electricity will be allocated and measured.
• How residents will be billed.
• Who will own, operate and maintain the system.
• What approvals and technical upgrades are required.

The objective is to create a practical energy solution with transparent costs and benefits for the people involved.

3. Community batteries and shared energy arrangements

What if your building has limited rooftop space or cannot accommodate a suitable battery installation?

Community batteries may provide another option to explore.

These batteries are installed in shared locations and can support participating households through specific energy programs, retailer arrangements or other local initiatives.

Depending on the project, residents may be able to access certain energy benefits without installing a battery inside their apartment or on their building.

However, availability, eligibility, costs and financial benefits vary. A community battery is not the same as a dedicated battery system for an apartment building, so both options should be assessed separately.

For buildings where an on-site installation is impractical, understanding the available local arrangements may be a useful first step.

A Potential Opportunity for NSW Apartment Buildings

New South Wales has introduced the Apartment Battery Storage incentive, with the program scheduled to become available from 1 September 2026.

The initiative is intended to support eligible battery installations at residential apartment buildings, with potentially greater discounts when qualifying battery storage is installed alongside new or additional solar capacity.

Program eligibility depends on the applicable requirements, including building characteristics, installation arrangements and battery specifications. The published criteria include a minimum of four residential units and outdoor battery installation requirements.

The owners corporation and relevant decision-makers should confirm the applicable requirements before progressing with a project.

Important: This is a NSW-specific initiative, not a universal rebate for all Australian apartment buildings. Incentive availability, discount amounts and eligibility conditions should be verified against the official program information before a project is quoted or approved.

For NSW strata committees already considering rooftop solar or improvements to common-area electricity costs, this may be a timely opportunity to investigate whether battery storage deserves further assessment.

What About Apartment Buildings in Other Australian States?

The opportunities available to apartment buildings vary across Australia.

Depending on the location, a building may be able to explore shared solar, battery storage, community energy initiatives or other approaches to improving electricity efficiency.

For some properties, the most practical starting point may be reducing common-area electricity consumption or assessing rooftop solar before considering a battery.

Several factors can influence which solution is suitable:

• Roof space: Is there enough suitable space for solar panels?
• Energy consumption: How much electricity does the building use, and when is demand highest?
• Metering arrangements: Can the proposed system serve common areas, individual apartments or both?
• Electrical infrastructure: Will upgrades be needed to accommodate the system?
• Installation space: Is there a suitable location for the battery and associated equipment?
• Approvals and safety: What strata approvals, electrical requirements, fire safety provisions and insurance considerations apply?
• Financial incentives: Are there current programs for which the building may qualify?

There is no single solution that suits every apartment complex. A building-specific assessment can help identify which options are worth exploring before money is committed.

Six Questions Your Strata Committee Should Ask Before Investing

Before considering a shared battery installation, owners corporations and property managers should establish the following.

1. Which electricity costs are we trying to reduce?

Review common-area electricity bills, available interval data and existing solar generation.

Understanding when and where electricity is consumed helps identify whether solar, battery storage or another energy improvement is likely to offer the greatest value.

2. Who will benefit from the system?

Determine whether the proposed installation will serve common property, individual apartments or a combination of both.

The ownership structure, billing arrangements and distribution of financial benefits should be clear before the project proceeds.

3. Is there enough solar generation to charge the battery?

Battery storage is not automatically economical simply because a building has solar panels.

The assessment should consider available solar generation, electricity consumption patterns, export rates, import tariffs and opportunities to charge the battery economically.

4. Where can the equipment be installed?

Battery location and system design must account for applicable electrical and fire safety requirements, building access, maintenance needs, installation conditions and relevant insurance considerations.

A qualified assessment can help establish whether the proposed location and installation approach are appropriate.

5. What approvals and incentives apply?

Determine the owners corporation’s decision-making process, project funding arrangements, connection requirements and any relevant government incentives.

Confirm eligibility before relying on a rebate or discount in the project’s financial calculations.

6. What is the realistic financial return?

Request an assessment that considers upfront costs, usable battery capacity, expected energy savings, maintenance, equipment life and applicable electricity tariffs.

Any projected savings or payback period should be supported by clear assumptions rather than generic estimates.

Is Battery Storage Worth Investigating for Your Apartment Building?

The answer depends on your building’s characteristics and energy requirements.

A low-rise complex with suitable rooftop solar and substantial common-area electricity consumption may present a different opportunity from a high-rise building with limited roof space and individually metered apartments.

For some properties, increasing solar self-consumption may be the priority. Others may benefit from a shared battery, an integrated solar and storage system, or an appropriate community energy arrangement.

The best starting point is to understand the building before choosing the technology.

A preliminary review of your property’s location, number of apartments, existing solar installation, electricity bills and electrical infrastructure can help determine which options deserve closer consideration.

For strata committees, this information can also provide a more informed starting point for discussions with owners, energy specialists and other relevant stakeholders.

Frequently Asked Questions (FAQs)

1. Can apartment owners benefit from battery storage without installing a battery inside their apartment?

Yes. Apartment owners may be able to benefit from shared battery storage installed for common areas or through an eligible shared energy arrangement. Depending on the building’s infrastructure and electricity setup, a community battery may also offer an alternative. The available benefits depend on the specific system and participation arrangements.

2. What is shared battery storage for apartments?

Shared battery storage is a central battery system designed to store electricity for use by a building or an eligible group of users. It can work alongside rooftop solar to help supply common-area electricity loads, such as lighting, lifts and ventilation.

3. Can a shared apartment battery reduce electricity bills?

It may reduce some electricity costs when the system is appropriately designed and operated. Savings depend on solar generation, electricity consumption, tariffs, battery efficiency, installation costs and how stored electricity is used.

4. Can an apartment building install solar panels and a battery?

Potentially, yes. Suitability depends on available roof space, structural considerations, electrical infrastructure, battery installation requirements, building access and relevant approvals. A site assessment can help determine whether a combined solar and battery system is practical for the property.

5. Does a strata committee need approval to install a shared battery?

A shared battery installation will generally require the appropriate owners corporation decision-making and approvals. The exact process depends on the proposed works, applicable strata legislation, ownership arrangements and building circumstances. Committees should confirm the relevant requirements before committing to a project.

6. Are there government rebates for apartment battery storage in Australia?

Potential incentives depend on the state or territory, the installation date, the property and the program’s eligibility rules. NSW has a Batteries for Apartment Buildings incentive scheduled to become available from 1 September 2026.

7. What if our apartment building does not have enough roof space for solar panels?

Limited roof space does not necessarily rule out every energy option. The building could investigate energy efficiency improvements, alternative solar opportunities or eligible community battery arrangements.

8. Can a shared battery power individual apartments as well as common areas?

It may be possible, but it depends on the electrical design, metering infrastructure, network arrangements and how electricity is allocated to participating apartments. A system designed only for common areas will not automatically supply individual units.

9. Can an apartment battery provide backup power during a blackout?

Potentially, but not every battery installation provides backup power. The system must be specifically designed and configured to supply selected circuits during an outage, with suitable equipment and electrical protection. Backup capability should be confirmed as part of the system design.

10. How much does it cost to install a shared battery in an apartment building?

Costs vary depending on battery capacity, installation location, electrical upgrades, integration with existing solar, metering requirements and project complexity. The number of apartments alone is not enough to determine the price. A property-specific assessment is needed to establish likely costs and potential savings.

11. How do we know whether our apartment building is suitable for battery storage?

Start by reviewing the building’s location, number of apartments, existing solar capacity, common-area electricity bills, electricity tariffs and available installation space. These details can help identify whether shared battery storage or another energy arrangement is worth investigating.

12. How can we enquire about apartment battery storage with EcoBridge?

You can contact EcoBridge using its official contact details or submit an enquiry through its website. Include your building’s suburb and state, approximate number of apartments, existing solar status and your role in the property.

Solar panels are excellent at generating electricity when the sun is shining. But there is one challenge many UK homeowners discover after installing solar: the time when your panels generate the most electricity isn’t always the time when your home uses the most electricity.

Solar generation is usually strongest during the middle of the day. At the same time, many households have relatively low electricity demand because people are at work, school or out of the house.

By late afternoon and evening, the situation can change.

The family comes home. Lights go on. Dinner is cooked. Appliances are switched on. Heating, hot water, EV charging and other electrical loads may all increase.

Unfortunately, this is also when solar generation begins to fall.

That is where a home battery can make a significant difference.

Instead of exporting surplus solar electricity during the day and then buying electricity from the grid later, a battery can store some of your excess generation and make it available when your household needs it.

For some UK homes, this can make battery storage one of the most valuable parts of a solar energy system.

---

The Solar Generation Problem: You Don’t Always Use Electricity When You Generate It

Imagine your solar panels are producing strongly at 1pm.

Your home might only be using a small amount of electricity because everyone is away.

Your solar system could therefore be generating more electricity than your home needs.

Without a battery, the surplus may be exported to the grid, depending on your system and electricity tariff.

Then, at around 6pm, your household’s electricity consumption increases.

You might turn on:

• Lights
• Oven and hob
• Television
• Dishwasher
• Washing machine
• Computers and devices
• Heating
• Hot water systems
• EV charging equipment

But your solar panels are now producing much less electricity — or none at all.

The result is a simple mismatch:

Solar generation: Highest during daylight hours
Household demand: Often higher in the morning and evening

A battery helps bridge that gap.

---

What Happens to Your Solar Energy After Sunset?

Once the sun goes down, your solar panels stop producing electricity.

Your household, however, continues using it.

Evening electricity consumption can be significant, particularly in homes with electric heating, EVs, heat pumps or several occupants.

Without enough solar generation, your home normally needs to import electricity from the grid.

A battery can change how your solar energy is used.

During the day

Solar → Home → Surplus → Battery

After sunset

Battery → Home

Instead of thinking of solar simply as a way to generate electricity during daylight, you can think of a solar-and-battery system as a way to generate, store and use electricity across a much larger part of the day.

---

Why a Battery Can Increase the Value of Your Solar Panels

Solar panels generate electricity.

But the value of that electricity depends partly on when you use it.

Consider two otherwise identical homes.

Home A: Solar Only

The solar panels generate electricity during the day.

The household uses some of it immediately.

Surplus electricity may be exported.

Later, when the sun has gone down, the household imports electricity from the grid.

Home B: Solar + Battery

The solar panels generate electricity during the day.

The household uses some immediately.

Surplus electricity charges the battery.

Later, the stored energy can be used in the home.

This gives the homeowner greater flexibility over when their solar electricity is consumed.

That doesn’t automatically mean a battery is financially worthwhile for every household. Battery economics depend on factors including:

• Electricity consumption
• Solar generation
• Import and export tariffs
• Battery capacity
• Installation cost
• Battery efficiency
• Household usage patterns
• Future energy requirements

For households with significant evening electricity consumption, however, battery storage can be particularly attractive.

---

The 4–7pm Electricity Challenge

For many households, electricity consumption begins increasing after work and school.

The household may go from relatively low daytime consumption to much higher demand in the evening.

This can be particularly important for homes with:

• Electric heating
• Heat pumps
• Electric vehicles
• Large appliances
• Home offices
• Multiple occupants
• High evening electricity consumption

The challenge is that solar generation may be falling precisely when household demand is increasing.

A battery effectively allows you to shift some of your daytime solar generation into the evening.

For example:

Daytime

Solar generation → Home → Surplus → Battery

Evening

Solar generation → Low/none → Battery → Home

This can increase the proportion of your solar electricity that is consumed within your property.

---

What Is Solar Self-Consumption?

Solar self-consumption refers to the electricity generated by your solar system that you use yourself rather than exporting.

For example, imagine your solar system generates 20 kWh during a day.

Your home directly uses 8 kWh while the panels are producing electricity.

The remaining 12 kWh could potentially be exported.

With a battery, some of that surplus can instead be stored and used later.

If you subsequently use 8 kWh from the battery during the evening, more of your own solar generation has been used within your home rather than being exported during the day.

This is one of the main reasons homeowners consider battery storage.

---

What About Selling Your Surplus Electricity?

Exporting surplus electricity isn’t necessarily a bad thing.

UK homeowners with eligible systems may be able to receive payments for electricity exported to the grid through an appropriate export tariff.

However, there is an important difference between:

Exporting surplus electricity

and

storing it and using it later yourself.

Which option provides greater financial value depends on your specific electricity and export tariffs.

For some homeowners, exporting a significant proportion of their solar generation may make sense.

For others, using more of their own electricity — particularly during higher-cost periods — may provide greater value.

That’s why choosing a battery shouldn’t simply be about buying the biggest battery available.

The system should be designed around how your home actually uses electricity.

---

Can a Solar Battery Be Charged From the Grid?

Yes. Depending on the solar battery UK system, tariff and installation configuration, a compatible battery may be able to charge from the grid as well as from solar.

This can be particularly interesting when using a time-of-use electricity tariff.

For example, a homeowner may be able to charge a compatible battery during a lower-cost period and use the stored electricity later.

However, not every battery, tariff or household will benefit from the same strategy.

The important point is that modern battery storage can potentially do more than simply store excess solar.

It can become part of a wider home energy-management system.

---

Should You Add a Battery If You Already Have Solar?

For many homeowners, it’s worth investigating.

UK households that installed solar several years ago may now have different energy requirements.

Perhaps you:

• Work from home
• Own an EV
• Have installed a heat pump
• Have a growing family
• Use more electricity in the evening
• Want greater energy independence
• Want to make better use of your existing solar generation

You may not need to replace your existing solar panels.

A battery retrofit may allow you to make better use of the electricity your existing system generates.

However, your existing inverter, electrical configuration and solar installation should be assessed before selecting a battery.

---

How Big Should Your solar battery UK Be?

Bigger isn’t always better.

A 20 kWh battery isn’t automatically a better investment than a 10 kWh battery.

The appropriate capacity depends on your household.

Key considerations include:

1. Your electricity consumption

A home using significantly more electricity may have a stronger case for larger storage.

2. Your evening consumption

If a large proportion of your electricity is consumed after sunset, battery storage may be more valuable.

3. Your solar system size

Your battery should be appropriately matched to your expected solar generation.

4. Your electricity tariff

Import and export rates can have a major impact on battery economics.

5. Your future energy requirements

Are you planning to:

• Buy an EV?
• Install a heat pump?
• Increase electric heating?
• Add other high-energy appliances?

Future electricity consumption should be considered.

6. Your budget

The most expensive battery isn’t necessarily the best battery for your home.

A good system design starts with your actual energy consumption rather than a standard battery size.

---

Do Solar Batteries Work During UK Winters?

This is one of the most common questions homeowners ask.

The UK has shorter daylight hours during winter, and solar generation can be significantly lower than during the summer.

A battery cannot create solar electricity when your panels aren’t generating enough.

However, depending on the system and electricity tariff, the battery may still provide value through energy management and, where supported, grid charging.

This is why a proper assessment should consider year-round electricity consumption and solar generation, rather than simply looking at a sunny summer day.

---

Solar Batteries for Electric Vehicle Owners

EV ownership can significantly increase household electricity consumption.

The timing of EV charging can also have a major effect on energy costs.

Your solar panels may generate electricity during the day while your vehicle is away.

A battery can potentially store some surplus solar energy and make it available later.

Depending on your tariff, battery system and EV charging schedule, smart charging strategies may also help manage electricity costs.

The ideal approach is to consider your:

Solar + Battery + EV Charger + Electricity Tariff

as one integrated energy system rather than four separate purchases.

---

Solar + Battery + Heat Pump

Heat pumps can significantly increase a home’s electricity requirements compared with traditional gas heating.

Combining a heat pump with solar and battery storage may allow a household to use more of its own renewable electricity.

However, the economics depend on several factors, including:

• Property size
• Insulation
• Heating requirements
• Heat-pump efficiency
• Electricity tariff
• Solar generation
• Battery capacity
• Heating schedule

A properly designed system should consider the home’s complete energy profile.

---

Is a Solar Battery Worth It in the UK?

There is no universal answer.

Battery storage may be particularly worth investigating if you:

• Already have solar panels
• Regularly export surplus electricity
• Have significant evening electricity consumption
• Own an EV
• Have a heat pump
• Want to increase solar self-consumption
• Want more control over when you buy electricity
• Have access to a suitable time-of-use tariff

On the other hand, a battery may not be the right investment for every household.

The better question isn’t:

“Is a solar battery good?”

It’s:

“Would a solar battery make financial and practical sense for my home?”

That’s where a personalised assessment can help.

---

Don’t Just Buy the Biggest Battery

One of the biggest mistakes homeowners can make is choosing a battery based purely on capacity.

The right system should consider:

Solar generation + electricity consumption + usage patterns + tariff + future energy needs

A household with relatively low electricity consumption may gain little from an oversized battery.

A larger household with an EV, heat pump and high evening consumption may have very different requirements.

The goal should be to install the right-sized system, not simply the largest one.

---

What Should You Check Before Installing a Solar Battery?

Before choosing a system, consider:

• Existing solar panel capacity
• Existing inverter
• Battery usable capacity
• Battery warranty
• Expected cycle life
• Round-trip efficiency
• Installation requirements
• Available space
• Electrical configuration
• Monitoring system
• Backup capability
• Electricity tariff
• Export arrangements
• Future electricity consumption

Professional design and installation are also important because battery storage is a significant electrical installation.

---

Your Solar Panels May Be Only Half the Story

Solar panels can reduce the amount of electricity you need to purchase from the grid during daylight hours.

But your home doesn’t operate only during daylight.

Your household may use more electricity after the sun has gone down — precisely when your solar panels are producing little or nothing.

That’s why battery storage has become an increasingly important part of the UK home-energy conversation.

The objective isn’t simply to generate electricity.

It’s to:

Generate it → store it when appropriate → use it when your home needs it.

For some households, a well-designed battery can therefore become just as important to the overall energy strategy as the solar panels themselves.

---

Is Solar + Battery Right for Your Home?

Every property is different.

The right combination of solar panels, battery capacity, inverter technology and electricity tariff depends on your home’s energy consumption and how you use electricity throughout the day.

Rather than guessing whether a battery could save you money, get your home assessed using your actual electricity consumption and energy requirements.

8. What happens to excess solar electricity without a battery?

Depending on your system and tariff, surplus electricity may be exported to the grid. You may receive an export payment if you have an eligible export arrangement.

9. Can a battery work with an electric vehicle?

Yes. Solar batteries and EV chargers can be integrated into a home’s wider energy-management strategy. The most suitable setup depends on when your EV is normally at home, when you charge it and your electricity tariff.

10. Can a battery work with a heat pump?

Yes. Solar, battery storage and a heat pump can form part of an integrated home energy system. However, system sizing should account for the property’s heating requirements and electricity consumption.

11. Will my battery work during winter?

Yes, but the battery itself does not generate electricity. Because UK solar generation is generally lower during winter, there may be less surplus solar available to charge it. Some systems may also support grid charging.

12. How long do solar batteries last?

Battery lifespan varies by manufacturer, chemistry, usage and operating conditions. Many modern home battery systems are designed for long-term use and come with substantial manufacturer warranties. The specific warranty should be checked before purchase.

13. Do I need a new inverter when installing a battery?

Not necessarily. It depends on your existing solar system and the battery technology being installed. Some systems can be retrofitted using additional equipment, while others may require a compatible hybrid inverter.

14. Can a solar battery provide backup power during a power cut?

Some systems can provide backup power, but this is not automatic. Backup capability requires the appropriate equipment, configuration and installation. If backup power is important to you, make sure it is specifically included in the system design.

15. Should I buy the biggest battery I can afford?

No. The biggest battery isn’t necessarily the most economical option. Battery capacity should be matched to your electricity consumption, solar generation, tariff and future energy requirements.

16. How can I find out what size battery my home needs?

The best approach is to assess your actual electricity consumption, solar generation, daily usage patterns and future energy requirements. A professional solar and battery assessment can then determine an appropriate system size.

For retail businesses across New South Wales, electricity is an essential operating expense. From refrigeration and air conditioning to lighting, point-of-sale systems, security equipment and other electrical appliances, energy consumption can have a significant impact on monthly overheads.

With electricity costs remaining an important concern for Australian businesses, more NSW retailers are exploring commercial solar and battery storage as a way to generate and use more of their own electricity.

The right commercial solar and battery storage NSW can help a retail business reduce its reliance on grid electricity while making better use of available roof space.

However, every retail business is different. The right system depends on how much electricity you use, when you use it and how your property operates.

Why Retail Businesses Are Considering Solar

Unlike many residential properties, retail businesses often consume electricity throughout the day.

Lighting, refrigeration, air conditioning, computers, POS systems and other equipment may operate continuously during trading hours. This can make daytime solar generation particularly useful.

Instead of purchasing all of that electricity from the grid, a commercial solar system can generate electricity on-site and allow the business to use that energy as it is produced.

Depending on the system design and the business’s electricity usage, solar can help reduce the amount of electricity purchased from the grid.

Common retail electricity loads include:

• Refrigeration and freezers
• Air conditioning
• Lighting
• POS systems
• Computers and IT equipment
• Security systems
• Hot water systems
• Kitchen equipment
• Display equipment
• Warehouse equipment

The higher the electricity consumption, the more important it becomes to understand exactly when and how that energy is being used.

How Battery Storage Can Add Value

Solar panels generate electricity during daylight hours, but many retail businesses continue consuming electricity after solar production starts to fall.

This is where battery storage can become useful.

A commercial battery can store excess solar energy generated during the day and make that stored energy available later, depending on the system configuration and energy management strategy.

For example, a retailer may have strong solar production around midday but continue operating into the evening.

Instead of exporting surplus solar energy, a battery may allow some of that energy to be stored for later use.

This can help businesses increase their use of the electricity they generate themselves and potentially reduce their reliance on grid electricity outside peak solar production hours.

Solar + Battery for Retail Businesses: How It Works

A typical commercial solar and battery storage NSW works around three main components:

Solar panels → Inverter → Battery storage

During daylight hours, the solar panels generate electricity.

The business can use that electricity according to the system’s energy management configuration. If solar generation exceeds immediate consumption, surplus energy can potentially be stored in the battery.

Later, when solar generation decreases, stored energy can be used to supply the business.

The exact operation depends on the system design, battery capacity, electricity tariff, network requirements and energy management settings.

Which Retail Businesses Can Benefit From Commercial Solar?

Commercial solar and battery storage can be considered by a wide range of NSW retail businesses.

Supermarkets and Grocery Stores

Refrigeration, freezers, lighting and air conditioning can create significant electricity demand.

Solar generation can potentially offset some of this daytime consumption, while battery storage may provide additional flexibility.

Convenience Stores

Convenience stores often have extended operating hours, refrigeration and lighting requirements.

A properly designed solar and battery system can be assessed against the business’s daytime and evening consumption.

Cafés and Restaurants

Commercial kitchens, refrigeration, hot water, air conditioning and lighting can all contribute to energy costs.

Solar can help offset daytime consumption, while battery storage can be assessed where electricity demand continues into the evening.

Pharmacies

Pharmacies can have consistent electricity requirements from lighting, cooling, refrigeration and other equipment.

Retail Showrooms

Large showrooms can have substantial lighting and air-conditioning requirements, making energy consumption an important operating cost.

Retail Warehouses

Businesses with large warehouse roofs may have significant potential for commercial solar generation.

However, roof condition, structural considerations, shading and electrical infrastructure should all be assessed before installation.

How Much Solar Does a Retail Business Need?

There is no single solar system size that works for every retailer.

A small independent shop may require a completely different system from a supermarket, showroom or large warehouse.

The appropriate system size can depend on:

• Annual electricity consumption
• Electricity usage during daylight hours
• Trading hours
• Roof size and orientation
• Available roof space
• Shading
• Electricity tariffs
• Existing electrical infrastructure
• Desired battery capacity
• Future energy requirements

This is why a commercial energy assessment should be completed before deciding on a system.

The objective isn’t simply to install as many solar panels as possible.

The objective is to design a system around the business’s actual electricity requirements.

Can Solar Be Installed Without Disrupting Retail Operations?

For many retailers, one of the biggest concerns is disruption.

A shop, supermarket, café or showroom cannot simply stop trading for an extended period while an energy project is completed.

Commercial solar installations can therefore be planned around the property’s operating requirements.

Before installation, the site can be assessed for:

• Solar panel locations
• Inverter placement
• Battery location
• Switchboard condition
• Cable routes
• Metering requirements
• Site access
• Roof access
• Electrical infrastructure
• Installation requirements

Understanding these factors beforehand allows the installation to be planned more effectively.

For larger commercial properties, additional electrical work may also need to be considered.

Commercial Battery Storage and Peak Electricity Usage

Electricity costs aren’t determined solely by how much electricity a business uses.

Depending on the business’s tariff and connection arrangement, when electricity is consumed can also be important.

A battery can provide the ability to shift some stored energy to periods when solar generation is lower.

However, battery economics vary from site to site.

The best approach is to examine the business’s actual electricity bills and consumption profile before recommending a battery size.

How Much Can a Retail Business Save With Solar?

There is no universal savings figure for commercial solar.

A retailer’s potential savings can depend on:

• Current electricity rates
• Annual consumption
• Daytime electricity usage
• Solar system size
• Battery capacity
• Solar self-consumption
• Export arrangements
• Business operating hours
• Future electricity requirements

For this reason, generic claims such as “solar will cut your electricity bill by X%” may not accurately represent what a particular business could achieve.

A better approach is to assess the business using its actual electricity data.

What Should a Business Provide for an Energy Assessment?

Getting started can be straightforward.

A commercial energy assessment may begin with:

1. A Recent Electricity Bill

This provides important information about the property’s electricity consumption and tariff.

2. Switchboard Photos

Photos can help identify the existing electrical infrastructure and potential upgrade requirements.

3. Meter Box Photos

Metering arrangements can be important when assessing a commercial solar project.

4. Property Information

Roof size, access, operating hours and business requirements can help determine an appropriate system design.

Once this information is reviewed, an energy assessor can determine whether solar, battery storage or a combination of both is worth exploring.

Is Solar + Battery Right for Your NSW Retail Business?

There is no one-size-fits-all answer.

For a business with significant daytime electricity consumption, commercial solar may provide an opportunity to generate electricity on-site.

For a business that continues using substantial electricity later in the day, battery storage may also be worth assessing.

The key is to understand your actual energy consumption before investing in a system.

A properly designed solar and battery system should work around your business operations rather than forcing your business to change how it operates.

Frequently Asked Questions

1. Is commercial solar suitable for retail businesses in NSW?

Commercial solar can be suitable for many retail businesses, particularly those with significant daytime electricity consumption and suitable roof space. The potential benefits depend on factors such as electricity usage, operating hours, tariffs, roof space and the property’s electrical infrastructure.

2. Can a retail business install solar and a battery together?

Yes. Solar panels and battery storage can be designed as an integrated system, subject to the property’s electrical infrastructure, network requirements, available space and the business’s energy requirements.

3. How does solar help reduce electricity costs for a retail business?

Solar generates electricity on-site that a business can use to meet some of its electricity demand. This can reduce the amount of electricity that needs to be purchased from the grid. The actual savings depend on the system size, electricity consumption, tariff, solar generation and how much solar energy the business uses.

4. Does a retail business need a battery if it has solar?

Not necessarily. A battery may be useful when a business continues to consume significant electricity after solar production decreases. Whether a battery is worthwhile depends on the business’s electricity consumption profile, tariff structure, solar system and energy objectives.

5. What size solar system does a retail business need?

There is no standard system size for every retailer. The appropriate size can depend on annual electricity consumption, daytime usage, trading hours, roof space, shading, electrical infrastructure, tariffs and future energy requirements.

6. What size commercial battery does a retail business need?

Battery capacity should be determined using the business’s actual electricity consumption and operating profile. Factors such as peak demand, solar generation, trading hours, tariff structure and the amount of energy the business wants to shift from daytime to later periods can all influence battery sizing.

7. Will installing solar disrupt my retail business?

Solar projects can be planned around a business’s operating requirements. Before installation, the site can be assessed for roof access, panel locations, inverter and battery placement, switchboard condition, cable routes and other installation requirements. Planning these details in advance can help minimise disruption.

8. What information does EcoBridge need for a commercial solar assessment?

A recent electricity bill is a useful starting point. Depending on the project, businesses may also provide electricity usage or interval data, property information, roof photos, switchboard photos, meter photos, existing solar information and details about the proposed battery location.

9. Can EcoBridge help businesses compare commercial solar and battery options?

Yes. EcoBridge describes itself as an independent energy solutions and comparison platform that helps Australian businesses understand commercial solar, battery, PPA, finance and other energy options and, where appropriate, connect with suitable accredited providers.

10. Can a business explore a PPA instead of purchasing a solar system?

Yes. A Power Purchase Agreement (PPA) can be one of the commercial energy structures businesses may explore. The suitability of a PPA depends on the property’s circumstances, energy consumption, contract terms and financial objectives.
