Methodology: How We Ranked the Best Solar Companies in Mill Valley
EcoWatch's solar experts analyzed each solar company in Mill 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 Mill 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 Mill Valley
For a lot of homeowners, whether or not to invest in solar energy comes down to the cost.There are several factors you should consider when trying to figure out the overall cost and how much you can save, such as:
- System size and type: Some models are more costly than others, so the one you choose can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
- Incentives: One thing that can make your solar project cost less 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 a decent amount of money on your energy bills, which can generate an average of $32,000 of savings over 20 years.
- The amount of sunlight your house gets: Due to Mill Valley’s very high amount of average daily sunlight, you should be able to save a lot on your electric bills.
- Electricity consumption: The average home in Mill Valley doesn’t use much energy, and consequently may not see as many savings on their power bills.
Though a solar panel system costs a sizable chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on several factors, including the angle of your roof and your local electricity rates.

How long does it take for solar to pay for itself?
The average payback period for solar panel installation is about 7.3 years, but the exact period varies depending on the cost of electricity where you are, incentives and net metering programs.
When should I install solar panels?
