OnSwitch

OnSwitch turns buying commercial solar into a web transaction. A building owner types an address and gets back a customized, contractible quote for the best-returning system available, built from high-resolution 3D aerial mapping and automated system design rather than a site visit and a sales cycle.

Commercial solar is bought the way it was in 2005: months of a building owner's attention, on top of their actual job, to find out whether the roof pencils. Most never start, which means most roofs stay empty. The same process saddles solar providers with customer acquisition costs high enough to eat the margin, so they can't grow profitably either. Both sides are losing to the same friction. Commercial rooftops are an enormous, well-mapped, already-wired surface sitting over the loads they'd serve, and the barrier is a quote nobody can get quickly.
