Methodology: How We Ranked the Best Solar Companies in Mammoth Lakes

EcoWatch's solar experts analyzed each solar company in Mammoth Lakes 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 Mammoth Lakes


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 Mammoth Lakes

When picking a solar company, most homeowners or business owners wonder about the costs above all.The cost of solar and the savings it generates vary depending on some important factors such as:

  • Choice of solar panels: The type of solar panels you buy will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also save you more money over the lifetime of your system. If you don’t need to maximize efficiency, you can opt for a higher number of more affordable panels.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 0 of the cost of your solar system installation from your taxes. Plus, not including incentives, you can save about $28,000 over 20 years on your energy bills.
  • Average daily sunlight: Since Mammoth Lakes gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which impacts how much your electricity bills will be.
  • Your household's power bills: With high monthly energy bills in Mammoth Lakes, you could save about $1,500 a year with solar.

What is the most reputable solar installation company in Mammoth Lakes?

The best local solar company in Mammoth Lakes is Berger Solar Electric, LLC, with a rating of 5.00 stars.

Are solar panels really environmentally friendly?

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

How long does it take for solar to pay for itself?

Solar panels usually pay for themselves in about 8.2 years, but your solar payback period will depend on your utility costs. The higher your typical energy bill, the faster your solar panel system will pay for itself.

What is the efficiency of solar panels?

Most of the time, solar panels are about 15 to 25% efficient, which means they can convert that percentage of the sun’s energy into usable electricity.
