How it works
From curious to switched on.
No magic numbers. Real weather data, real utility rates, and a clear path from your address to a payback date. You stay in control the whole way.
Enter your address and pin your roof to create a precise model of your home's sunlight. Then place the panels as you see fit.
Our philosophy
Choosing solar should start with understanding it.
Solar has a sales problem. Most homeowners meet it through a pitch at the door, with numbers that change from quote to quote and no way to check them. We think you should see your own roof and your own numbers before anyone tries to sell you anything. So we put the tools the experts use in your hands. Understand first. Then choose an installer you can trust, and we'll help you find one.

A classic. Two roof faces, two orientations. Compare where the panels earn their keep.
Angles everywhere. See how an odd, stepped roof still adds up to real production.
Room for a big array. Watch production, savings and payback scale with the roof.
