Methodology: How We Ranked the Best Solar Companies in Windham

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


Below are some the criteria we examined specifically for Connecticut 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 Windham

The cost of putting up solar panels has decreased significantly over the past few years, but it's still a large investment for most homeowners. There are several factors you should take into consideration when determining how much it will cost and how much you can save, including:

  • System size and type: Some models are more expensive than others, so the one you want to get can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 30% of your overall installation cost, your local government may offer additional tax exemptions, credits or rebates that can help you save even more. Not including incentives, you can save an average of $22,000 over the first 20 years with your solar system, too.
  • How much power your household consumes: Households that consume plenty of power each month may require more solar panels and, therefore, be more costly, but will also benefit more over time.
  • How much sunlight your roof gets: If your roof doesn't get a lot of direct sunlight, your solar panels won't be able to produce as much energy, which will give you lower savings on electricity bills than a roof that gets lots of sunlight.

Even though a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on several factors, like the size of your house and your energy consumption.
