Methodology: How We Ranked the Best Solar Companies in Fountain Valley

EcoWatch's solar experts analyzed each solar company in Fountain Valley based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Fountain Valley


Below are some the criteria we examined specifically for California solar companies

  • Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
  • Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
  • Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
  • Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
  • Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
  • Availability (10%): The bigger the service area, the higher the company will score.
  • Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
  • Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.

The Cost and Benefits of Solar in Fountain Valley

For many people, the decision of which solar installer to go with depends on pricing.The installation cost is just one important factor you should take into account when looking into getting solar panels. How much it'll cost and how much you can save depend on things including:

  • The kind of solar panels you can afford: This depends on your income and budget.
  • How much sunlight your roof gets: If your roof gets limited direct sunlight, your solar system won’t be able to make as much energy, which will give you lower savings on electricity bills than a house with a roof that gets plenty of sunlight.
  • How much energy you use: If your family regularly uses a lot of energy, you'll reap more rewards from installing solar panels.
  • Your household's power bills: Based on the high monthly electric bills in Fountain Valley, you could save about $1,200 a year with solar.

Even though a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on a number of factors, like the size of your solar panel system and your local electricity rates.

EcoWatch's Fountain Valley, CA Solar Company Rankings FAQs

Which solar power company is the best in Fountain Valley?

The top local solar company in Fountain Valley is SunPower by Sun Solar-OC, with a rating of 3.00 stars.

Are solar panels really environmentally friendly?

Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to recycle safely once they’ve reached the end of their lifespan. Making solar panels needs a lot of energy as well. The energy payback period is about 1 to 4 years.

Is it worth installing solar panels on my roof?

Solar panels need a significant upfront investment that will cost you several thousands of dollars, but whether or not solar panels are worth it depends on a variety of factors like local electricity rates and how much direct sunlight your roof gets.

What are the different types of solar panels?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and how much energy generation you want.
