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

Solar panels run off a free energy source — the sun — but to take advantage of this you must first pay to install your panels.The cost and possible savings vary depending on a few important factors such as:

  • Incentives: Something that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save on your power bills, which can give you an average of $32,000 of savings over 20 years.
  • System size and type: Some models are more costly than others, so the one you decide on can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
  • The amount of sunlight your roof gets: Thanks to Alta Sierra’s very high amount of average daily sunlight, you should be able to save a lot on your electric bills.
  • Your current electricity bills: Solar panels can substantially decrease, or totally get rid of, your utility bills. In Alta Sierra, you can save an average of $1,538 a month.

Even though a solar panel system costs a decent 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, including the angle of your roof and your local electricity rates.

EcoWatch's Alta Sierra, CA Solar Company Rankings FAQs

Which solar company is the best near me?

The best local solar company in Alta Sierra is Sunrun Solar, with a rating of 3.00 stars.

What is the negative environmental impact of solar panel manufacturing?

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.

Are solar panels worth it?

Solar panels can be a great investment for a majority of homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your energy bills are already fairly low, solar panels might not be for you.

When is the best time of year to install solar panels?

Although summer is the most common time people install solar panels, the perfect time is actually winter. You can save money since there's not as much demand during the winter months, and it lets you be up and running with solar for the higher power bills you may get during the summer.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
