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

For many readers, the decision of which solar company to hire comes down to costs.There are several factors you should consider when trying to figure out how much it will cost and how much you can save, such as:

  • Incentives: The federal solar investment tax credit currently lets you lower your taxes by 0 of the project cost. Your state may also have various incentives that you can benefit from. In addition, you can save about $32,000 over 20 years on your utility bills, not including incentives.
  • Your income and budget: This guides what model of solar panels you can afford.
  • Average daily sunlight: Since Alta Sierra gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which affects how much your solar panels can save you on your electricity bills.
  • Your home's power bills: Based on the fairly high monthly energy bills in Alta Sierra, you could save about $1,500 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 several factors, such as the kind of solar panels you get and your local electricity rates.

Environmental Impact of Switching to Solar in Alta Sierra

There are many reasons to make the switch to solar energy, like saving on electricity bills and helping to reduce your carbon footprint.You may be trying to figure out – how much does going solar help the environment anyway? Switching to green energy for electricity in place of using nonrenewable energy is a great way to reduce your carbon footprint if you're conscious of Alta Sierra's fair level of greenhouse gas emissions.Since solar panels don’t release carbon dioxide emissions into the atmosphere when generating electricity, they’re a good alternative to traditional energy sources.

Since solar energy is renewable and produces electricity without a carbon footprint, installing solar panels is one easy step you can take to help the environment.
