Every roof plane, measured
Find a building by address or drop a pin, and see each roof plane's size, pitch, direction and sunshine, from aerial surveys of the roof.
For community energy organisations
Find the roofs for your next community solar project
RoofPitch estimates the solar potential of a building's roof in minutes: panel layouts, generation, savings and a proposal to share. It's for community energy organisations looking for rooftops to put solar on.
What it does
Built on Google's Solar API, with the Centre for Sustainable Energy's Solar Wizard model for a second opinion on the roof.
Panel layouts you can adjust
Start from Google's layout, or the Solar Wizard's own roof detection, then choose which roof planes to use and how many panels to fit.
The numbers for a rooftop PPA
Estimate yearly generation, how much the building will use on site, and what your PPA saves the building owner against their grid tariff over the project.
A proposal to share
Download a PDF proposal with the layout on a satellite image, ready to send to the building owner or put in front of your board.
Community energy organisations
Community-owned rooftop solar depends on finding the right buildings: roofs with the space and the sun, and owners who use the power during the day. RoofPitch helps your team find them and make the case.
Accounts are for organisations working with Big Solar Co-op. If you'd like one for your team, get in touch through bigsolar.coop.
