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

For a lot of homeowners, whether or not to invest in solar panels boils down to the cost. The cost and possible savings vary depending on a few key factors such as:

  • Typical energy usage: The more energy your home consumes on average and the larger your current energy bills are, the more money you could save by switching to solar.
  • The amount of sunlight your rooftop gets: Thanks to Windsor's very high amount of average daily sunlight, you should be able to save a lot on your power bills.
  • Your income and budget: This determines what model of solar panels you can purchase.
  • Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 30% of the project cost. Your state and city may also have various incentives that you can benefit from. In addition, you can save about $19,000 over 20 years on your utility bills, without incentives.

So is a solar panel system worth it? Whether you hope to reduce your electricity costs, carbon dioxide emissions or both, solar panels are a good investment for many Windsor homeowners.

Environmental Impact of Switching to Solar in Windsor

Switching to solar energy can have a positive impact on the environment. But you may be curious — how much exactly can you help the planet by going solar? If your household uses lots of energy, you can have an even greater impact on the planet by switching to solar power. While solar panel production releases carbon dioxide emissions, the panels make up for it by greatly lowering the amount of CO2 you would have been responsible for if you still used traditional energy. In Windsor, you can reduce your carbon footprint by 100 pounds a year with solar panels. Since energy from the sun is abundant and makes electricity without a carbon footprint, making the switch to solar power is one easy step you can take to help the environment.

EcoWatch's Windsor, CO Solar Company Rankings FAQs

What is the top solar panel installation company in Windsor?

The highest-rated local solar company in Windsor is Freedom Solar Power, with a rating of 4.13 stars.

What is the negative environmental impact of solar panel manufacturing?

Solar panels can be bad for the environment when manufacturers use toxic chemicals when they're made. Chemicals can make solar panels difficult to dispose of safely once they've reached the end of their lifespan. Making solar panels needs a lot of energy as well. The energy payback period is about 1 to 4 years.

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 9.6 years, but the exact period is influenced by the cost of electricity where you are, incentives and net metering programs.

How long do solar panels last?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable. What this means is how much energy they produce will have decreased by about 0.8% each year since installing them. You can opt to replace them after having them for that long or you can keep using them at a lower efficiency after that time.

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.
