LAST UPDATED: July 10th, 2024
Sun First Solar was founded in 1984 and services California customers in the Bay Area. The company believes in a "consultative approach" to improve the environment and community. With the claim that it can "help intelligent people make smart solar decisions," Sun First Solar provides full-service solar system design and installation. It handles the project from the initial planning through to activation, meanwhile providing diagnostics, repairs, and maintenance services, including cleaning.

The Good

  • Time in Business
  • Reputation
  • Variety of Payment Options

Time in Business

Sun First Solar has been around for over three decades. Compared to many solar companies that have only been in business for a few years, Sun First Solar has the history and reputation to put customers at ease.


In its 32 years in business, Sun First Solar has received a lot of positive feedback. Additionally, the majority of the reviews Sun First Solar receives on independent sites like Yelp and SolarReviews are very positive. "I cannot rate the service that I've received to date with Sun First Solar highly enough, and if I could give them six stars, I would." - Ravi K. Novato, CA "Sun First came through for us on a difficult job.....guiding us smoothly to the final hookup. All staff were polite, efficient and professional. We would recommend their services without hesitation." - Rob J. San Rafael, CA

Variety of Payment Options

Sun First Solar allows customers to pay with cash, to finance, or to lease their solar systems. Paying cash results in the best return for investment, but if a customer doesn't have the funds at the moment, he or she can either finance or lease the system. Financing ultimately allows a customer to own the system at the end of the contract. Leasing essentially replaces a monthly electronic payment for a lower monthly solar lease payment until the end of a contract period.

The Bad

  • No Monitoring App
  • Limited Information Available from Customer Service

No Monitoring App

Sun First Solar does not have a company app for customers to monitor their energy usage. Instead, customers are encouraged to use the app available through the inverter manufacturer.

Limited Information Available from Customer Service

As with most solar energy companies, a lot of detailed information was not available on the Sun First Solar website. The customer service rep that we spoke with on the phone was polite and helpful, but didn't know a lot of answers to questions, such as efficiency ratings or warranty information.

The Bottom Line

Although some important key information is not readily available unless a customer is willing to go through the process of receiving a detailed quote, Sun First Solar has a sterling reputation with customers over its more than three decades in business. The company has much of the same standard offerings as competitors when it comes to panels, inverters, warranties, etc.; however, its customer service seems to be what sets Sun First Solar apart. Additionally, there's little risk of going out of business or dramatically changing the company structure since Sun First Solar has proven to be a robust and thriving solar company since 1984.

Olle Larsson Corte Madera, CA

The company representetive came to our home three times to assess the best way to do the installation on the house. I was pleased with the advice and calculations of our power need. The over all price is very competitive. Because the company is located in our county it is very easy to visit their office in case of any questions. Everybody is friendly and helpful. Would I use them again? Absolutely! I would not go anywhere else. Olle L. Corte Madera, CA
