Methodology: How We Ranked the Best Solar Companies in Redwood City
EcoWatch's solar experts analyzed each solar company in Redwood City 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 Redwood City
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 Redwood City
We know that for many homeowners, the choice to invest in solar rests on installation costs.The installation cost is just one important factor you should bear in mind when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:
- Typical energy usage: The more energy your household consumes on average and the steeper your current energy bills are, the more likely you'll benefit from going solar.
- Your income and budget: This shapes what type of solar panels you can purchase.
- Your location: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
- Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 0 of the cost of installing your solar panel system from your taxes. In addition, not including incentives, you can save about $33,000 over 20 years on your energy bills.
Solar is a worthwhile investment for most homeowners. You can produce your own power instead of paying for it from the grid and make use of solar incentives and rebates, all while helping preserve the planet.

What is the negative environmental impact of solar panels?

Solar panels can be a beneficial investment for lots of homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get enough sunlight or your energy bills are already reasonably low, solar panels might not be for you.
When is the best time of year to install solar panels?
You can install solar panels whenever it's convenient for you, but consider doing so in the winter when the demand is less. With fewer homeowners switching to solar, you could potentially see quicker installation times and more savings.
