In Sun We Trust digitalizes the rooftop solar market. Rooftop solar has a gigantic potential, but low information among homeowners and high acquisition costs makes it difficult to scale. We solve this by providing high-precision, remote estimates of any rooftop’s solar potential. How does it work? With a simple address and little information, the users can discover the profitability of any rooftop. Then, they can design their very own solar projects. And we do not stop there… We restore France’s trust in solar energy. How do we do that? We are the one-stop-shop for hassle-free solar. We guide home and business owners at every step of their solar projects. We put our users in touch with local solar installers, who have gone through a strict selection process. Last but not least, we have 50+ partnerships with local authorities, covering 6 million people all over France, whom we help boost the local solar market. These partnerships have established In Sun We Trust as a reliable actor in the solar market.
