Had a good experience having the team come out for the install. Gabriel was a good person to talk to and was always prompt following up. The installation team came out quick and finished within a couple of hours.

Good experience working with Solar Optimum

I am at bay area. In my particular case Solar Optimum worked perfectly on their side. The whole thing (from signing the contract to my seeing the output power from the Enphase app) took only a month. I was the one to be blamed for a minor delay because my first check sent to LA cannot be cashed out (and JPMorgan cannot explain why) so I needed to resend one.

Best in terms of quality, performance, price and warranty.

After talking and comparing quotes from multiple solar companies. I signed contract with Solar Optimum to install solar panels.Their prices were competitive, and the customer service was top-notch and I'm happy with the whole experience. They are best in terms of quality, performance, price and warranty. From the beginning, the Solar Optimum team answered all my questions and made the process a breeze. My sales consultant Gabriel Alvarez <> is experienced, professional, friendly, knowledgeable, and truly cared about my satisfaction. He was prompt in responding to my queries over emails and available over phone to answer my questions.My experience with Gabriel Alvarez my sales consultant was very positive.

Good job

Our sales rep did a good responding to us, usually answering in less than a day. He clearly answered questions and helped us understand costs. After signing the contract our installation was completed in about two months. The installation crew was hard working and professional.

Great experience start to finish: Great equipment, great value, installed on time!

I did a ton of research and got more than 10 quotes for my job, some through Energy Sage and several independently. I chose Solar Optimum and they did a great job start to finish. I am happy to recommend them to anyone looking to install solar. First: Solar Optimum honored their quote on Energy Sage. Other companies did not. Value: Solar Optimum was nearly the lowest quote, and definitely the best value considering the high quality Panasonic and Enphase equipment they used. Schedule: They met or beat their schedule at every step. Communication: It was always easy to reach a knowledgeable person when I had a question about the next project phase. Company Experience: Solar Optimum is the right size. They're a large enough company to have systems in place for every step of the work. They're not the largest, so they still care about each job. Trustworthy: They delivered the equipment we discussed at the price they promised, on the schedule they committed. Couldn't ask for more. I know one other company that quotes one panel and then delivers another. Not Solar Optimum. Overall, I'm happy that I got great equipment on time at a great price. Thank you Solar Optimum!

Fast installation

Solar Optimum did a great job. They finished the entire project within several weeks. This was super fast. And the quality was good. The installer asked for and listened to my proposal on how to run the wires.
