See what solar would do for your home

Two things — your address and last year's electricity use. You'll get a system size, a production estimate and a price range before we ask who you are.

The property

Street address

Do you own it?

Roof age, in years

An approximate figure is fine.

Electricity use

Twelve months beats an annual total, because your summer and winter pattern decides how much of your bill solar can actually cover.

Total kWh over the last year

Your bill shows this as annual usage. Leave it blank if you fill in months below.

Enter it month by month instead

Electric vehicle, miles per year

Adding a heat pump or electric heat?

We show new load separately, and never use it to justify a bigger system than your utility permits.

Your roof

Panels last 25 years or more. If the roof underneath has less life than that, it is far cheaper to replace it before the array goes on than to remove and refit the array later.
