Your business runs its own way. Your energy should fit.
Start with the working day. We’ll work through the solar and batteries.
Start by looking at where daytime energy demand overlaps with solar generation.
An illustration to help the conversation. Your actual load profile needs to be checked.
Explore this direction I’d rather talk it throughA business that uses electricity during solar hours has a useful starting point for a commercial solar discussion. Your actual load profile, tariff and roof determine the design.

Get a feel for the investment before we get into the details. Commercial solar projects start at 30 kWp DC, with the final design shaped by your site and operating profile.
The current commercial delivery phase covers combined inverter capacity up to 200 kVA. Capacity, battery scope and pricing are confirmed through site, engineering and network assessment.
100% onsite use · Synergy L1 benchmark
Assumes all solar energy is used onsite as generated. Typical modelled generation; actual results vary and are not guaranteed.
30 kWp × 4.4 kWh per day per kWp × 365 days = 48,180 kWh a year, using the Australian Government’s typical Perth generation benchmark. This is a modelled illustration, not a physical maximum.
The Synergy L1 first-tier usage rate, effective 1 July 2026, is 33.1278 c/kWh including GST. Dividing by 1.1 gives 30.1162 c/kWh excluding GST. At 100% onsite use as generated, that models $14,509.98 a year in avoided energy charges, rounded above.
L1 is an illustrative benchmark, not an eligibility assumption. Your business may use L3 or a contracted tariff. Actual tariff, daytime load, roof, weather and system performance vary. No export credits, fixed-charge or demand-charge savings are included; operating costs are not deducted. A site assessment establishes your business case.
After applicable STCs for a standard rooftop installation. Excludes unusual network, structural, switchboard, access and other site-specific costs. Larger systems and batteries require assessment.
Discuss the scopeStart with the monthly electricity bill and when the site operates. This first view only establishes current annual spend. Savings, system size and payback need real load, tariff, roof and network evidence.
Use a typical recent month. The annual figure below is this amount multiplied by 12.
The details of commercial solar, battery storage and installation in Perth, before you decide.
Our indicative 30 kWp DC solar marker is $19,990 ex GST. After applicable STCs for a standard rooftop installation. Excludes unusual network, structural, switchboard, access and other site-specific costs. Larger solar systems and batteries require assessment. Your written quote confirms the complete scope and final price.
Start with when your premises use electricity, then consider the tariff, available roof space, electrical supply and future plans. Matching solar generation to demand is part of the assessment; a system size alone cannot establish the business case.
Start with your operating hours, tariff and demand profile. Battery storage and any backup requirements need their own assessment alongside the solar design. We’ll review equipment compatibility, engineering and network requirements before confirming the scope.
We consider electricity data, roof structure, switchboard works, site access and network requirements. Engineering is included as part of the solar or battery package. Installation details and exclusions are confirmed in your written quote.
Finance can be arranged if required, subject to provider approval. Discuss the options as part of your commercial project conversation.
PSW Energy works with businesses across Perth, Mandurah and Peel within the South West Interconnected System. Our local team works from Bibra Lake and Neerabup. Tell us where the project is and we’ll confirm the pathway.
Enough for an owner, operations lead or receptionist to start the conversation. Only the organisation, contact name and email are required.
Location, project interest and any bill or operating detail you can provide.
Usually electricity data, site access, roof information and network constraints.
A PSW Energy team member will confirm whether the project fits the current scope.
