Minute to design it: Solar design apps save time creating proposals for owners

In a sales environment where only one in 10 viable solar projects moves forward, getting from a good idea to a firm decision by a customer needs to happen fast. Here’s how one commercial solar installer makes technology work.

Hosting capacity maps: A gold mine for solar developers

Multiple U.S. states require electric utilities to share their power grid data with solar developers. The resulting tools are like treasure maps for solar developers.
