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
Best for California Residents
Solar Optimum sells high-quality monocrystalline solar panels from various manufacturers, including Enphase, Panasonic Solar, Qcells, REC, Tesla, Unirac. The provider holds top certifications with all those manufacturers, allowing it to offer and stand by its comprehensive product warranties.
Solar Optimum also installs solar backup batteries. Options include the Tesla Powerwall and Enphase IQ.
Warranty Options
The company has some of the most impressive warranty offerings in the industry. Customers get a 25-year warranty on panels, power production, inverters, racking systems, workmanship, and roofing services.
Installation and Offered Services
Solar Optimum prides itself on handling everything during the installation process for its customers. After submitting a quote request and deciding to move forward with the company, you’ll get a free consultation to discuss your energy needs and solar system preferences. There will be a site assessment to determine the exact system size and arrangement that’s right for your property, followed by a permitting request with your municipality, which Solar Optimum will handle. Its certified team will install your panels and then connect them to the grid if you choose.
The provider also offers roof installation, repair, and replacement services.
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.
Solar Optimum offers four financing options:
- Full purchase: Purchasing your solar power system in full up-front is the best route since you’ll own your system from day one.
- Solar loan: A loan is your next best option. You’ll make monthly payments until you pay off your system, but you’ll still be the owner.
- Solar lease: If you choose a solar lease, Solar Optimum will own your system, and you’ll pay for the energy generated, like a monthly electricity bill. We don’t recommend this option since this disqualifies you from some solar incentives.
- Power purchase agreement (PPA): When you have a PPA, your provider sells the power generated to you at a fixed rate that’s typically lower than your local utility’s retail rate. Again, we don’t recommend this since you won’t own the system.
