people in front of solar

The SunEngine team embarked on creating a better platform for community solar subscription management because we saw a gap in the marketplace. Our goal is to build better software and processes on a budget through day-to-day innovation.

Our platform is unique because it leverages our experience in the trenches, knocking on doors and signing people up. Moreover, we are hands-on, meaning that we work side-by-side with our project owner partners.

With all of our collective projects, we drive to innovate around every challenge, to be responsive, to follow up diligently, and to care deeply about the end-user. This results in massive dividends down the road as we grow.
