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 Colorado 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

The cost of putting up a solar panel system has dropped significantly over the past few years, but it’s still a large investment for most homeowners.The installation cost is just one important factor you should consider when looking into installing solar panels. How much it'll cost and how much you can save depend on things including:

  • The type of solar panels you have the money for: This hinges on your income and budget.
  • Your power bills: This will affect your savings. In Windsor, the average resident can save about $980 a year on their electricity bills.
  • Incentives: One thing that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that’s equal to a percentage of the project cost. You can also save on your energy bills, which can lead to an average of $19,000 of savings over 20 years.
  • Average daily sunlight: Since Windsor 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.

Though a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars over the lifespan of your panels. The question of how much, though, depends on a number of factors, including the kind of solar panels you get and incentives.

Environmental Impact of Switching to Solar in Windsor

If you’re considering adding solar panels to your home, one of the primary reasons why may be to lower your reliance on nonrenewable energy.But how much can installing solar panels actually affect the environment? Switching to green energy for electricity instead of burning fossil fuels is an impactful way to lower carbon dioxide emissions if you're concerned about Windsor's large level of greenhouse gas emissions.Though making solar panels releases carbon dioxide emissions, the panels make up for it by considerably reducing the amount of CO2 you would have produced if you still used traditional energy.

EcoWatch's Windsor, CO Solar Company Rankings FAQs

Which solar company is the best near me?

The highest-rated local solar company in Windsor is Smart Wave Solar, with a rating of 4.80 stars.

Are solar panels really environmentally friendly?

Making solar panels needs to use chemicals and produces toxic waste that can be harmful for the environment, which is the main downside of solar panels.

How long does it take for solar to pay for itself?

The average payback period for solar panel installation is about 14.2 years, but the exact period depends on the cost of electricity where you are, incentives and net metering programs.

How often do solar panels have to be replaced?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is how much energy they produce will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can keep using them at a lower efficiency after that time.
