As electricity prices continue to rise across New South Wales, commercial property owners are increasingly looking at solar panels and battery storage as a long-term investment. For landlords, installing solar on commercial buildings is no longer just a sustainability initiative—it can improve property value, attract quality tenants, reduce operating costs in common areas, and create new revenue opportunities.

However, not every commercial property is suitable for the same solar and battery solution. Before investing, landlords should assess the building’s energy usage, roof suitability, electrical infrastructure, and financial returns.

This guide explains how NSW commercial landlords can evaluate the solar and battery potential of their properties and make informed energy decisions.

Why Commercial Landlords in NSW Are Investing in Solar

Commercial solar adoption is growing across NSW because many commercial properties use significant electricity during daylight hours—the same time solar panels generate the most energy. Solar can help reduce reliance on grid electricity while improving the property’s environmental credentials. Commercial landlords are increasingly exploring solar and battery solutions to reduce electricity costs, improve energy resilience, and increase control over energy consumption.

Benefits of Solar for Commercial Property Owners

• Lower electricity costs for shared building services.
• Increased property value and tenant appeal.
• Reduced exposure to rising electricity prices.
• Better sustainability and ESG performance.
• Potential eligibility for available commercial solar incentives.
• Opportunity to integrate battery storage for greater energy flexibility.

Whether you own an office building, warehouse, retail centre, industrial facility, or mixed-use commercial property, a properly designed solar system can support long-term operating savings.

Step 1: Assess Your Commercial Roof Space

The roof is one of the most valuable assets for a commercial solar installation.

What to Check

Roof Assessment Factor	Why It Matters
Available roof area	Determines how many solar panels can be installed.
Roof orientation	North-facing roofs generally maximise solar generation in NSW, although east and west roofs can also perform well depending on energy demand.
Roof pitch	Influences solar panel efficiency and mounting design.
Shading	Trees, neighbouring buildings, HVAC equipment, and signage can reduce energy production.
Roof condition	An older roof may require repairs before solar installation.
Roof material	Metal, Colorbond, concrete tile, and membrane roofs each require different mounting systems.

Roof Suitability Checklist

• Large unobstructed roof sections.
• Minimal daytime shading.
• Structurally suitable roof.
• Enough clearance around equipment and access pathways.
• Remaining roof lifespan aligns with solar panel lifespan.

Step 2: Understand the Building’s Electricity Usage

The best commercial solar system starts with electricity data—not roof size alone. A professional assessment should consider the property’s actual consumption profile, operating hours, tariffs, and future electricity needs.

Collect Recent Electricity Bills

A recent electricity bill helps identify:

• Total electricity consumption.
• Peak demand charges.
• Time-of-use tariffs.
• Daily usage patterns.
• Meter type.
• Network charges.

Questions Landlords Should Ask

• Who pays the electricity bill?
• Is electricity separately metered for tenants?
• Are common areas landlord-funded?
• Are there multiple tenancies?
• Are operating hours mostly during the day?

Understanding these answers helps determine how much solar energy can be consumed on-site versus exported.

Step 3: Evaluate Tenant Energy Consumption

Different tenants consume electricity differently.

Commercial Tenant Type	Typical Daytime Solar Usage
Office buildings	High weekday daytime consumption.
Retail stores	Strong daytime usage during trading hours.
Warehouses	Often consistent daytime operational loads.
Industrial facilities	Can have large daytime equipment loads.
Medical centres	Long daytime operating hours.
Shopping centres	Shared common area loads plus tenant usage.

The closer solar production matches daytime electricity demand, the greater the potential financial benefit.

Step 4: Check Electrical Infrastructure

Commercial solar may require assessment of existing electrical infrastructure.

Key Items to Review

• Main switchboard capacity.
• Metering configuration.
• Distribution boards.
• Existing solar system compatibility.
• Grid connection requirements.
• Available inverter location.
• Cable pathways.
• Fire and safety compliance.

Older buildings may need electrical upgrades before installing a larger solar system.

Step 5: Determine the Right Solar System Size

There is no universal best commercial solar size.

System capacity depends on:

• Annual electricity consumption.
• Daytime load.
• Roof size.
• Budget.
• Export limits.
• Future expansion plans.
• Battery integration.

Typical Commercial Solar Sizes

Property Type	Indicative Solar Range
Small office	20–30 kW
Retail building	30–60 kW
Warehouse	50–150 kW
Industrial facility	100–500+ kW
Shopping centre	100 kW to multi-megawatt

A professional assessment should size the system around energy consumption rather than installing the maximum number of panels.

Step 6: Assess Whether Battery Storage Makes Sense

Solar panels generate electricity during the day.

A commercial battery stores excess solar energy for later use.

Battery Storage Can Help With

• Evening electricity use.
• Peak demand reduction.
• Time-of-use tariff optimisation.
• Backup power for selected circuits.
• Greater solar self-consumption.
• Energy resilience during outages.

Factors

Factor	Importance
Daytime solar surplus	Determines charging potential.
Evening electricity demand	Determines battery usage.
Peak demand charges	May improve battery value.
Battery capacity (kWh)	Should match property load profile.
Power output (kW)	Determines how much load battery can support.
Backup requirements	Optional feature depending on business needs.

Battery storage should be designed around the property’s actual electricity profile rather than selecting the largest battery available.

Commercial landlords should understand available financial pathways before investing.

Possible Options Include

• Small-scale Technology Certificates (STCs) for eligible systems.
• Large-scale Generation Certificates (LGCs) for qualifying projects.
• Commercial battery incentive programs where applicable.
• Power Purchase Agreements (PPAs).
• Equipment finance.
• Operating leases.
• Outright purchase.

The most suitable option depends on property ownership, electricity usage, and investment objectives. EcoBridge helps businesses compare commercial solar, battery, and PPA options across Australia.+1

Step 8: Calculate Potential ROI

Commercial solar is a long-term investment.

Factors That Affect ROI

• Electricity prices.
• Solar system size.
• Battery inclusion.
• Daytime self-consumption.
• Export tariffs.
• Installation complexity.
• Maintenance costs.
• Financing structure.

Typical Financial Assessment Includes

Assessment Item	Purpose
Annual electricity savings	Estimate reduced grid consumption.
Solar generation forecast	Estimate yearly production.
Battery savings analysis	Evaluate load shifting benefits.
Payback estimate	Understand investment timeframe.
Cash flow projection	Review long-term savings potential.

Step 9: Consider Future Energy Needs

Solar systems should be designed with future expansion in mind.

Future-Proof Your Commercial Property

Think about future additions such as:

• EV charging stations.
• Heat pumps.
• Additional tenancy.
• Building extensions.
• Battery expansion.
• Increased operating hours.

Planning ahead can reduce future upgrade costs.
