Our Mission

To build a community of designers who care about solving tomorrow’s energy problems today. These may seem like just a few words, but they’re truly meaningful for all of us here at SepiSolar. We genuinely care about our work, each other, our clients, and the community.  In fact, the community of designers that we’re building includes everyone. How people create and use energy guides our solutions for transitioning the world to renewables and a more intelligent grid.

Our Design

Technology SepiSolar has developed proprietary solar and storage design tools that create solar plan sets that achieve faster permitting and utility interconnection approvals, keeping projects on time. In fact, most of SepiSolar designs receive approval without revisions. Our technology is flexible, allowing Helioscope, Aurora, and other third-party proposal tools to be seamlessly incorporated to our full plan sets.
