Methodology: How We Ranked the Best Solar Companies in Alta Sierra

EcoWatch's solar experts analyzed each solar company in Alta Sierra 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 Alta Sierra


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 Alta Sierra

The cost of putting up solar panels has gone down immensely over the past few years, but it's still a large investment for most homeowners. There are a few factors you should take into consideration when determining how much it will cost and how much you can save, such as:

  • Typical energy usage: The more energy your home uses on average and the larger your current energy bills are, the more money you could save by going solar.
  • Incentives: Something that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that's equal to a percentage of the project cost. You can also save money on your energy bills, which can result in an average of $32,000 of savings over 20 years.
  • Your income and budget: This guides what model of solar panels you can get.
  • Average daily sunlight: Since Alta Sierra gets lots of sunlight, your solar panel system will most likely be able to generate enough energy to power your whole home, which affects how much your solar panels can save you on your electricity bills.

There are lots of wonderful benefits of solar even with the initial cost of installation. It can help the environment and your bank account. In addition, it can raise the value of your home, leading to even more benefits if you choose to sell your home later.

Environmental Impact of Switching to Solar in Alta Sierra

Using solar power is one of the easiest things you can do to help. In Alta Sierra, the average household can reduce their carbon footprint by 50 pounds a year after going solar. For people who want to help the environment, the upfront cost of solar is a small price to pay for reducing your carbon footprint.
