Good questions.

Is my roof covered?

We can measure hundreds of millions of buildings worldwide. If yours is not covered yet, we tell you instead of guessing.

How close is the estimate to a real quote?

It starts from your roof’s measured faces and a modelled year of sun, so it is far closer than a zip-code average. An installer’s site visit confirms the final design and price.

Are incentives included?

Sample figures on this page are before incentives. Live estimates add federal, state and utility incentives where they apply in your area.

Which panels do you assume?

A standard 400 W panel, 1.879 by 1.045 m, modelled over a 20-year life.

What do you do with my address?

We use it to look up your roof and show you the result. Nothing else happens with it unless you ask an installer to contact you.

Why we built this

Every homeowner should see what their roof can earn before anyone knocks on the door.
