Using SepiSolar for designing and engineering Swell Energy’s solar-plus-storage systems was a no-brainer. Storage is complicated, so we wanted to work with a team of U.S.-based quality engineers who could speak ‘fluent storage’ and get out accurate plan sets quickly and with minimal AHJ revisions.”

Co-Founder, Swell Energy


The price of failure with defects on a finished project is severe, and it’s simply not worth trying to save a few dollars upfront only to be bitten down the road with failures. That’s why we partner with SepiSolar for all of our engineering and design needs for solar and storage.”
