Methodology: How We Ranked the Best Solar Companies in Windsor

EcoWatch's solar experts analyzed each solar company in Windsor 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 Windsor


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 Windsor

When deciding on a solar company, most homeowners or business owners worry about the costs the most. Some significant things that impact the cost and possible savings include:

  • Average daily sunlight: Since Windsor gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which impacts how much your electricity bills will be.
  • Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 30% of the project cost. Your state may also have various incentives that you can benefit from. Plus, you can save about $32,000 over 20 years on your utility bills, before factoring in incentives.
  • Your income and budget: This affects what kind of solar panels you can buy.
  • How much you spend on energy: The average family in Windsor pays around $1,000 a year on energy use alone, so you could end up with that much in savings.

Solar is a rewarding investment for most homeowners. You can make your own electricity instead of paying for it from a utility company and take advantage of solar incentives, all while helping the Earth.

Solar Incentives in Windsor

Switching to solar power has a lot of considerable benefits. Not only can it help preserve the environment, but you can also save some money on your installation with various government incentives. You are eligible for the federal solar investment tax credit (ITC) for the tax year you turn on your solar panels. You can also potentially stack the ITC with other state and city rebates and benefits. Our article on solar incentives has more detailed information on the incentives you can take advantage of in Windsor.

Environmental Impact of Switching to Solar in Windsor

One of the reasons so many are thinking of installing solar panels is to help reduce their environmental impact. But you may be curious — how much exactly can you help the planet by using solar power? Something that can dramatically influence your carbon footprint is your commute time and how much you drive altogether. If you install solar panels and drive an electric car, you can vastly reduce your carbon dioxide emissions by charging your car at home. Once you go solar, your carbon footprint can be reduced by about 50 pounds a year. For people who are worried about the environment, the upfront cost of solar is a small price to pay for reducing your carbon footprint.

EcoWatch's Windsor, CA Solar Company Rankings FAQs

What is the best solar panel company in Windsor?

In Windsor, Dragon Off Grid Solutions: Solar & Batteries is the top local solar company. Our team of experts rates it 3.00 stars, so it's a great choice if you're looking to install solar panels on your home.

What are the pros and cons of solar power?

The advantages of solar power are that it can reduce or, in some cases, entirely eradicate your electricity bills, raise your home's value and cut back on your carbon footprint. The disadvantages are that solar panels can be costly to install, you may not save a lot if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.

How long does it take to see a return on your investment after buying solar panels?

The average payback period for solar panel installation is about 5.6 years, but the exact period is influenced by the cost of electricity where you are, incentives and net metering programs.

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 costly. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types 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 layout and how much energy generation you want.

Our goal is to reach as many people as we can with sensible solutions like solar energy. Our team of full-time local researchers collects solar price and installation data for every city in America then compiles it to create these digestible city guides.
