Great designers consider more than just the technical specifications. SepiSolar engineers consider local regulatory requirements, aesthetics, and cost-effective design solutions to maximize production, reduce equipment costs, and take full advantage of the project’s rate structures, exceeding customer expectations.

Joshua Weiner,
Founder and President


The best engineers in the world are never finished until the project is done.

Aarti Punase,
Solar Design Engineer


Engineers shouldn’t only follow code, but also follow common sense.

Tiffany Hanson,
Project Manager


Engineers should be transparent. We clearly show both customers and permit plan checkers the codes and reasons behind our design choices.

Court McKinney,
Senior Design Engineer


Engineers should be ethical. An ethical engineer is conscious of the impact their work has on the world.

Richard Dobbins,
Chief Electrical Engineer


We believe that SepiSolar customers deserve poised, polite, and prompt communication; polished plan sets; and a continuously improving experience.

Taylor Bohlen,

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


We’ve been working with SepiSolar since 2010 for our residential, commercial, and industrial solar and energy storage projects. The reason we’ve worked with them for so long is as a result of the quality of work and expertise. Xero Solar stands behind all of our installations, and this is only as good as the design they are built on.”

Ben Lochtenberg,
CEO of Xero Solar


Sunlight Electric has been working with SepiSolar since 2012, and they’re our trusted partner for quality solar engineering work. Their engineering team is current on code, best practices, and their work product is well-received by AHJs.”

Rob Erlichman,
Founder of Sunlight Electric


SepiSolar has been providing us with commercial solar engineering services for the last three years, producing our construction drawings and providing us with useful insight to difficult questions that we run into.
