Methodology: How We Ranked the Best Solar Companies in San Francisco
EcoWatch's solar experts analyzed each solar company in San Francisco 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 San Francisco
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 San Francisco
Even though solar panels can help save you a decent chunk of change on energy over time, it's important to take into consideration the upfront costs. Some main factors that influence how much it will cost to install a solar panel system on your home and how much money you could save over time are:
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 30% of your total installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Excluding incentives, you can save an average of $31,000 over 20 years with your solar panels, too.
- System size and type: Some models are more costly than others, so the one you choose can raise or lower your initial investment. Plus, the more solar panels you need to get, the more it'll cost.
- Your current power bills: Solar panels can significantly reduce, or completely eradicate, your utility bills. In San Francisco, you can save an average of $84 a month.
- How much sunlight your roof gets: If your roof doesn't get a lot of direct sunlight, your solar panels won't be able to produce as much energy, which will leave you with lower savings on electric bills than a house with a roof that gets lots of sunlight.
Even though a solar panel system costs a decent chunk of money upfront, it can save you much more over the lifespan of your panels. The question of how much, though, depends on a number of factors, like the kind of solar panels you get and your local electricity rates.

Solar Incentives in San Francisco
If you're thinking about making the switch to solar energy, several government incentives and subsidies can immensely bring down the installation costs and expedite the return on your investment. You can qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your a solar panel system. You can also potentially use the ITC with other local rebates and benefits. In our article on solar incentives, you can find out about the incentives you qualify for near you.
Environmental Impact of Switching to Solar in San Francisco
Installing solar panels is a powerful way to do your part for a cleaner and more sustainable future. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in San Francisco, though. One thing to keep in mind is your overall carbon footprint. For example, if you spend a lot of time in the car and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions. Because solar panels don't release CO2 emissions into the atmosphere when creating electricity, they're a good substitute for traditional energy sources. In fact, you could look forward to lowering your carbon dioxide emissions by about 50 pounds each year. As you can see, trading traditional energy for solar has so many other benefits besides saving money. One of the primary ones is that you can help save the environment too.

Are solar panels actually eco-friendly?

The average payback period for solar panel installation is about 5.9 years, but the exact period varies by the cost of electricity where you are, incentives and net metering programs.
When should I install solar panels?
