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

For a lot of homeowners, whether or not you should invest in solar panels boils down to the cost.The installation cost is just one important factor you should bear in mind when looking into installing solar panels. How much it'll cost and how much you can save depend on things such as:

  • How much power your home consumes: Households that use a lot of energy each month may require more solar panels and, consequently, more upfront cost, but will also enjoy more savings over time.
  • Choice of solar panels: The kind of solar panels you are interested in getting 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.
  • Average daily sunlight: Since Redwood City gets lots of sunlight, your solar panel system will most likely be able to generate enough energy to power your whole home, which impacts how much you can save on your energy bills.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 0 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. Excluding incentives, you can save an average of $33,000 over 20 years with your system, too.

Even though a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on several factors, including the angle of your roof and your local electricity rates.

Solar Incentives in Redwood City

In an effort to increase solar panel installation and usage, incentives are offered by the government – and even some utility companies – to help make switching to solar power more financially viable and accessible.Local solar incentive programs depend on the location and, sometimes, utility company. Many states offer rebates for solar power, in addition to the federal solar tax credit. In our article on solar incentives, you can see the incentives you qualify for in your area.

Environmental Impact of Switching to Solar in Redwood City

Making the switch to solar power is a compelling way to do what you can for a greener future.A question many homeowners might be thinking about is how much can they really help the environment by switching to solar power anyway? Adopting solar power is an impactful choice for the environment, because the greatest source of greenhouse gas emissions in the nation is from burning fossil fuels for electricity, heat, and transportation – all of which can be powered by solar instead.While solar panel production emits carbon dioxide, the panels make up for it by greatly reducing the amount of CO2 you would have produced if you still used traditional energy. In Redwood City, you can reduce your carbon footprint by 50 pounds a year with solar panels. If you want to do what you can for the environment, you’ll no doubt find that there are many advantages to adopting solar power other than just saving money on bills. You can also help protect the environment, which some would argue is more valuable.

EcoWatch's Redwood City, CA Solar Company Rankings FAQs

Which solar panel installer is the best near me?

In Redwood City, SunPower is the top local solar company. Our team of experts rates it 4.50 stars, so it's a solid choice if you're planning to add solar panels to your roof.

Are solar panels really good for the environment?

Solar panels can be bad for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Solar panel manufacturing requires a lot of energy as well. The energy payback period is about 1 to 4 years.

Are solar panels worth it?

Solar panels require a large upfront investment that will cost you several thousands of dollars, but whether or not solar panels are worth it depends on a variety of factors like how much you pay for electricity and the amount of direct sunlight your roof gets.

When should I put up solar panels?

Although summer is the most popular time people install solar panels, the ideal time is actually winter. You can save money since there's decreased demand during the winter months, and it allows you to be up and running with solar for the more expensive power bills you may get during the summer.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
