About RadiusX
We think the sun shouldn't cost anything.
RadiusX was founded by a roofer, an engineer, and a community organizer who believed clean electricity shouldn't be reserved for the people who can pay for it upfront. So we built a way that anyone can. And for every roof we finish, we fund another somewhere else in the world.
