Zach was quick to assess the property and did a great job of explaining the product that he offered and letting me decide if he was a good fit (he didn't feel like a pressuring salesman). He took on the job at a difficult time for the solar industry with the impending termination of the tax credit. The project had some delays and bumps along the way—communication was poor at times—but he saw the job through to the end. I believe he did a good job. Very happy with my system thus far. No regrets w

We hired Sierra Solar to install some panels and a new inverter/batteries for an off grid system. He was professional, very reasonably priced, and completed the work quickly. VERY happy with Sierra Solar!

Zach, Pita, and crew did a great job upgrading our old solar array. Super fast and easy to work with. Definitely recommend!

Sierra Solar installed panels at the office I work at in Bishop and was such a pleasure to work with! They kept us informed through the process and were super responsive whenever we had questions. The entire process went much faster then expected. Grateful for Zach and his dedicated team for getting the office up and running with clean energy!

Zach and crew were a pleasure to work with: communication was quick & easy, there was no pressured up-sell, and he answered all my questions. I appreciated that Zac

Something to bear in mind is that this system is unsurprisingly high tech and you will want people who can service this system. If you ask around, you will find th

We hired Sierra Solar a little over a year ago to have solar panels put on our home in Mammoth Lakes. Zack did a fabulous job. Everything he promised, he fulfilled, including the timeline of when he would do the installation. We have been very happy with the job and thoroughly enjoy no longer having an electric bill. It’s been worth it. Cindie W. Mammoth Lakes
