Commercial Solar

Commercial solar power systems from 20kW to 100kW-plus, custom-proposed to offset daytime business energy use and shorten payback.

Commercial solar power systems

Commercial solar power systems are what we specialise in. Solar for your business is a great way to reduce your energy bill, and it usually results in a quicker payback period than residential — because most businesses operate during the day, which is exactly when your solar system is producing.

Commercial Solar FAQ

Your commercial solar questions, answered

Why is commercial solar worth considering?+
Solar for your business is a great way to reduce your energy bill, and it usually results in a quicker payback period than residential solar. That is because most businesses operate during the day, which is exactly when a solar system is producing — so more of the generation is used on site rather than exported.
What size are commercial solar systems?+
Commercial solar systems are usually in the range of 20kW to 100kW, with large-scale systems going beyond 100kW. The right size depends on your building, your roof space and your daytime energy use, which is why we put together a custom proposal rather than quoting a standard system.
How does commercial solar reduce our bill?+
Our custom solar proposals are designed to offset and reduce your energy bill, often resulting in a credit where there are no restrictions. Because business energy use largely happens during daylight hours, a well-sized system can cover a significant share of consumption and cut down what you draw from the grid.
Do you provide a custom proposal for commercial solar?+
Yes. Commercial solar power systems are a core specialty for us, and every commercial job is custom-proposed. We look at your building, roof space and energy use, then design a system intended to offset your daytime consumption and shorten the payback period.
What sort of payback can a business expect?+
Commercial solar usually has a quicker payback than residential because daytime generation lines up with daytime business use. The exact payback depends on your energy use, tariff and system size, which is why we work it through in your custom proposal rather than quoting a generic figure.
Can commercial solar reduce our carbon footprint?+
Yes. Alongside the financial benefit, commercial solar reduces your business's carbon footprint while delivering a drastic reduction in energy cost. For many businesses that combination of lower bills and lower emissions is a strong reason to move ahead.
How do we get started with commercial solar?+
Contact us to discuss your business and arrange an assessment. From your building, roof space and energy use we prepare a custom proposal showing the recommended system size and the expected reduction to your energy bill.
