Methodology: How We Ranked the Best Solar Companies in San Mateo
EcoWatch's solar experts analyzed each solar company in San Mateo 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 Mateo
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 Mateo
We know that for most homeowners, the decision to invest in solar rests on installation costs.The installation cost is just one important factor you should consider when looking into getting solar panels. How much it'll cost and how much you can save depend on things including:
- System size and type: Some models are more costly than others, so the one you want to get can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.
- Energy consumption: Installing a solar system may be a high-cost option for households that don’t need too much energy each month.
- The amount of sunlight your roof gets: Thanks to San Mateo’s very high amount of average daily sunlight, you should be able to save a lot on your power bills.
- Incentives: One thing that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save on your power bills, which can result in an average of $33,000 of savings over 20 years.
There are several good benefits of solar despite the initial cost of installation. It can help the Earth and your finances. Additionally, it can increase the value of your home, leading to even more benefits if you choose to sell your home later.

Environmental Impact of Switching to Solar in San Mateo
One reason so many homeowners are considering installing solar panels is to help bring down their environmental impact.Something many people might be asking themselves is how much can they really help preserve the environment by going solar anyway? One thing that can drastically shape your carbon footprint is how long your commute is and how much you drive in general. If you go solar and drive an electric car, you can vastly cut back on your carbon dioxide emissions by charging your car at home.Since 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 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 offsetting your carbon emissions.
EcoWatch's San Mateo, CA Solar Company Rankings FAQs
What is the best solar panel installer in San Mateo?
The highest-rated local solar company in San Mateo is Solar Bill Review, with a rating of 5.00 stars.
What are the advantages and disadvantages of solar power?
The main advantages of solar power are that it can lower or, in some cases, totally eradicate your electricity bills, raise your home’s value and cut back on your carbon footprint. The main disadvantages are that solar panels can be pricey to install, you may not save a lot if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.
How long does it take to see a return on your investment after buying solar panels?
Solar panels typically pay for themselves in about 7.1 years, but your solar payback period will vary based on your utility costs. The higher your typical energy bill, the faster your solar panel system will pay for itself.
What are the different types of solar panels?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof configuration and desired energy output.
