A 25kW commercial solar system costs approximately $18,000 to $25,000 before the STC discount is applied. For a small business with an annual electricity bill between $4,000 and $8,000, a 25kW system is typically the right fit and delivers an annual saving of approximately $3,500 to $5,500 depending on tariff structure and daytime load profile. The STC discount is applied upfront by Sunflare and is calculated based on your system size, location, and the current deeming period. [CONFIRM CURRENT STC VALUES WITH CLIENT.] The number on your Sunflare quote is the net cost after STC is deducted.

Warehouse and factory system size depends on your daytime load profile, operating hours, and roof area. A warehouse drawing 60 to 80 kW during operating hours typically suits a 70kW system. A factory drawing 90 to 120 kW during peak hours suits a 100kW system. Sunflare reviews your NMI interval data before specifying a system size. The right size is the one that matches your actual peak consumption window, not a generic square-metre estimate.

Commercial solar installations in Victoria access the federal STC scheme only. The Solar Victoria rebate applies to residential installations exclusively. For a commercial system under 100kW, the STC discount is applied upfront by Sunflare and is calculated on system size, climate zone, and the current deeming period. [CONFIRM CURRENT STC VALUE WITH CLIENT.] Systems above 100kW access the Large-scale Generation Certificate (LGC) scheme instead of STCs.

For a business with $12,000 or more in annual electricity costs and consistent daytime operations, payback typically runs 4 to 6 years at current tariff rates with STC applied. Perth warehouses with 100kW+ daytime loads are seeing payback under 5 years. Victorian light industrial operations at the 39.9kW tier are typically seeing payback in 4 to 6 years. [CONFIRM CURRENT PAYBACK RANGE WITH CLIENT based on current tariffs and STC.] Sunflare provides your specific payback period on the quote document before you sign.

Yes. Flat commercial roofs are installed using engineered mounting frames designed to Australian Standards. Sunflare conducts an on-site roof assessment covering orientation, pitch, material, and load-bearing capacity before the system is specified. Flat roof frames are tilted to the optimal angle for your location and secured to the roof structure. Network connection applications and all distributor approvals are managed by Sunflare end to end.
