What's the payback on commercial solar?
It depends on your bill, your tariff and how much power you use in daylight. The calculator above gives an indicative payback, and our energy audit of your bills and meter data gives you the real figure.
Can you install without shutting down operations?
Yes. We schedule installation around your trading hours, so your business keeps running while we work.
What size system does my business need?
We work it out from your utility bills and meter data in an energy audit, so the system matches when you actually use power. The calculator above gives a first estimate.
Will the system keep running during a power outage?
Only if it includes batteries. A grid-tied system without batteries switches off when the grid goes down, for safety. A system with battery backup keeps tills, servers and security running.
What types of businesses is commercial solar suited to?
Businesses that use most of their power in daylight: offices, retail and shopping centres, warehouses and logistics, light manufacturing, and schools and churches.
What happens after the system is installed?
We commission the system, set up monitoring and look after ongoing maintenance, so it keeps performing.
