Methodology: How We Ranked the Best Solar Companies in Tamalpais-Homestead Valley

EcoWatch's solar experts analyzed each solar company in Tamalpais-Homestead Valley 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 Tamalpais-Homestead Valley


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 Tamalpais-Homestead Valley

The cost of installing a solar panel system has gone down significantly in the past few years, but it's still a significant investment for most homeowners. A few key factors that affect the cost of installing solar panels on your home and how much it could save you over time are:

  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Aside from incentives, you can save an average of $32,000 over 20 years with your solar panels, too.
  • Choice of solar panels: The kind of solar panels you choose will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings 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.
  • Your household's power bills: Because of fairly high monthly electric bills in Tamalpais-Homestead Valley, you could save about $1,100 a year with solar.
  • How much sunlight your roof gets: This, plus how your roof is set up, affects affect how much power your solar panels can make.

Due to the cost of solar panels being lower than before as well as several solar incentives, they are a sound investment for most homeowners.

In fact, if you adopt solar power, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. For people who are concerned about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.
