Solar Optimum Reviews

We read more than 100 customer reviews on sites such as the Better Business Bureau (BBB), Google Reviews, and Best Company. Overall, Solar Optimum’s customer feedback is some of the best we’ve seen when analyzing solar providers. Positive reviews cite great customer service, responsiveness, and smooth and timely installations. A few customers reported opposite experiences, which may be due to personnel at select locations rather than a widespread company problem.

Here’s a sample of the reviews we analyzed:

Solar Optimum is super easy to work with and made the whole experience seamless. And they do a ton of follow-up in order to maintain the experience going forward!” —Michael L. via BBB

“They constantly shifted deadlines. Their office would say something different every time I called, and their ‘official’ emails said something completely different. It’s one thing to be busy and have delays, but it’s another to keep moving the bar to where I have to fight the company every step of the way.” —Matthew G. via Google Reviews

“Overall, it’s a great company to deal with—very prompt with scheduling, and great job on installation. Best part is, when you call, you actually get to talk to a person! It seems like the company is smaller compared to competitors, but it’s nice because requests and questions do not get lost in the abyss!” —Rory T. via BBB

“Initially, they estimated installing 19 panels, but after the measurements, they reduced it to 13. And that is ok, but it took them months to change the layout. I had to call them almost every week to nudge them to do something. I was more interested in moving this project forward than they were. Finally, we scheduled installation. After the installation and after I got the ‘permission to operate’ (PTO), it turned out that the panels didn’t work. After a few days of the calls and multiple ‘Please, turn on and off your system/breakers/panels,’ they submitted a repair ticket that they promised to review in five business days. And it is still open.” —Hennadiy H. via Google Reviews

Solar Optimum Cost and Payment Options

Like most solar panel companies, Solar Optimum doesn’t provide costs on its website. This is likely because system costs vary greatly based on size, features, brand, and other factors.

We looked at average solar costs for California, where Solar Optimum has the most locations. According to EnergySage, system costs in the state range from $14,850 to $29,700, with the low end being a 5-kilowatt (kW) system and the high end being a 10-kW system. You’ll likely be on the lower end if you live in a smaller home or have minimal electricity usage. You’ll need a bigger system if your home has multiple stories, many appliances, or overall high electricity needs.
