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.”

Andrew Meyer,
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.”

We submitted our RFP proposal to the utility today, and I wanted to thank SepiSolar for the excellent service you provided. Your ability to provide a detailed engineering design on a tight turnaround time was impressive. Your input helped us secure an updated solar design that met all of the RFP’s requirements. We look forward to working with SepiSolar again on future projects.”
