How it works
We look at your roof from space
Using Google's satellite data, we model your exact roof, its orientation, and how much sun it gets.
We ask a few questions
About how you live in the home, when you use electricity, and what you've already got.
We tell you straight
A real fit score, real costs, real savings, and whether it's actually worth it for you.
