39kW Commercial Solar System
Good for small warehouses, offices, medical practices and retail sites with strong weekday daytime use. Typically needs about 88 panels at 440W [VERIFY] and three-phase power.

Commercial Business Case
The 39kW commercial solar system is an industrial-grade solution designed using high-efficiency 440W Tier-1 solar panels (approximately 88–90 panels [VERIFY]).
Delivering a nominal capacity of approximately 38.7kW to 39.6kW, this system is engineered to reduce daytime operating costs for small-to-mid businesses. Paired with a heavy-duty commercial three-phase inverter, it provides reliable, continuous power generation throughout business operating hours.
Ideal Applications
Good for small warehouses, offices, medical practices, and retail sites with strong weekday daytime power usage.
Financial Model & STCs
Every commercial site receives an individual assessment showing gross cost, Small-scale Technology Certificate (STC) discount, and transparent pricing. Payback is modelled based on your specific interval data, daytime self-consumption, and electricity tariffs rather than generic assumptions.
