LAST UPDATED: August 10th, 2023

Option One Solar has been in business for nearly 50 years and has more than 57 years of extensive electrical experience dating back to 1961. When it comes to electrical, and especially solar, experience matters because the solar system will be connected to a high voltage utility grid. Because of this, it pays to have the installation completed by a highly experienced and professional electrical contractor. Option One is not just a solar company, but a licensed C-10 electrical contractor and a licensed C-46 solar contractor.

Top Ranked Companies


The Good

  • Mobile Home–Compatible Systems
  • Low APR Solar Loan Financing Option
  • 25-Year Comprehensive Warranty
  • NABCEP-Certified Solar Installer
  • High-Performance Solar Equipment
  • Tesla Powerwall Certified Installer

Mobile Home–Compatible Systems

Option One Solar is one of the few solar installation companies that provides mobile home–compatible solar panel systems. The only stipulation is that the mobile home have a permanent foundation. That said, the solar company does not install on RVs or motorhomes.

Low APR Solar Loan Financing Option

The solar company offers a number of low APR solar financing solutions. Rates are as low as 0%, and terms range from 12 to 25 years. Next to direct cash purchase, solar loan financing offers the fast and most profitable return on investment for homeowners. It also qualifies homeowners for solar incentive plans, including the Federal Tax Credit.

25-Year Comprehensive Warranty

Option One Solar offers customers a comprehensive, 25-year system warranty that includes the following coverages:

  • Solar panels and inverters
  • Racking and mounting equipment
  • Labor and workmanship
  • System performance
  • Roofing (where applicable)

NABCEP-Certified Solar Installer

Option One Solar has been certified by the North American Board of Certified Energy Practitioners (NABCEP), which identifies the company as a competent and trustworthy renewable energy contractor. 

High-Performance Solar Equipment

Although Option One Solar offers customers an array of equipment from multiple manufacturers, the company primarily installs solar panels from Hyundai, and solar inverters from SolarEdge. Hyundai's new line of monocrystalline solar panels are highly resilient against nearly all weather conditions, rank among top players for energy efficiency, and come with a manufacturer-backed 25-year warranty.

Tesla Powerwall Certified Installer

In addition to its high-quality energy system, Option One Solar also installs the Tesla Powerwall, which is one of the most reliable and popular solar battery options on the market. As a backup power option, the Tesla Powerwall allows homeowners to store surplus solar energy and use it at night or in emergencies. 


The Bad

  • SoCal Solar Installation Only
  • No Lease or PPA
  • No Verified Option One Solar Reviews

SoCal Solar Installation Only

Option One Solar's solar energy system is only available in  Southern California, including the following cities:

  • Barstow
  • Mojave
  • Murrieta
  • Palm Springs
  • Rancho Cucamonga 
  • Riverside
  • San Bernardino
  • Victorville
  • and many more

If you live in Southern California, widely considered one of the most compeitive solar markets in the country, we encourage you to read the latest Option One Solar reviews and see how this company compares to other residential solar providers in your area.

No Lease or PPA

Not only does Option One Solar not offer solar leases or power purchase agreements as financing options, the company actively discourages homeowners from pursuing these options. While it's true that direct purchase and solar loan financing provide the best return on investment, solar leases and PPAs can be an effective option for homeowners who lack the out-of-pocket resources to finance the system themselves.

No Verified Option One Solar Reviews

As of January 2023, Best Company has yet to receive any verified reviews for Option One Solar. Verified reviews offer potential solar customers an additional level of authenticity regarding the solar companies they research. A lack of verified reviews can prevent customers from learning more about a company's customer service, solar installation process, and system performance dificult.

If you are a current or former Option One Solar customer, we encourage you to post your review below.


The Bottom Line

Overall, Option One Solar has almost everything a homeowner could want in a reliable solar provider. The company has been serving Southern California residents for more than 50 years and installers high-quality systems protected by robust, 25-year warranties. Furthermore, Option One Solar has been endorsed by the NABCEP, one of the most trusted organizations in renewable energy.

The only real surprise for a company of Option One Solar's longevity is the lack of verified reviews. That aside, we encourage anyone interested in solar to reach out to this company for a free quote and energy audit, and compare their findings to other reputable solar companies in Southern California.
