Methodology: How We Ranked the Best Solar Companies in Angwin

EcoWatch's solar experts analyzed each solar company in Angwin 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 Angwin


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 Angwin

For many people, the decision of which solar company to choose comes down to how much it'll cost. The cost of solar and the savings it generates vary depending on some important factors such as:

  • How much sunlight your roof gets: If your rooftop doesn't get a lot of direct sunlight, your solar panel system won't be able to make as much energy, which will leave you with lower savings on energy bills than a roof that gets a lot of sunlight.
  • Incentives: The federal solar investment tax credit, which can save you some money, allows you to deduct 30% of the cost of installing your solar panel system from your federal taxes. Plus, not including incentives, you can save about $33,000 over 20 years on your energy bills.
  • The make and model of solar panels you're thinking of getting: Some cost more, so that will determine your budget for your solar project.
  • Electricity consumption: The average household in Angwin doesn't use much energy, and as a result may not see as many savings on their power bills.

Due to solar panels decreasing in cost as well as several solar incentives, they are a worthwhile investment for most homeowners.

Solar Incentives in Angwin

Because solar power is a cleaner source of energy than traditional energy sources, there are various government incentives in place to encourage people to make the switch. There are a lot of federal, state and local rebates and tax credits that let you earn a decent amount of money back after installing solar panels. In our article on solar incentives, you can see the incentives you qualify for near you.

Environmental Impact of Switching to Solar in Angwin

Going solar can have a beneficial effect on the environment. A question many homeowners might be wondering about is how much can they really help preserve the environment by going solar anyway? If your home uses a lot of energy, you can help the environment even more by switching to solar power. Because solar panels don't release CO2 emissions into the atmosphere when creating electricity, they're a good swap for traditional energy sources. In fact, you could reduce your carbon dioxide emissions by about 50 pounds each year. For homeowners who are worried about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.
