Methodology: How We Ranked the Best Solar Companies in Guilford

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


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 Guilford

For many people, the decision of which solar company to choose comes down to prices. A few important factors that influence the cost of installing a solar panel system on your home and how much money you could save over time include:

  • The type of solar panel system you can buy: This hinges on how much you're willing to invest upfront.
  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, allows you to deduct 30% of the cost of installing your solar panel system from your federal taxes. Plus, not including incentives, you can save about $25,000 over 20 years on your energy bills.
  • Your current electric bills: Solar panels can greatly decrease, or totally eradicate, your utility bills. In Guilford, you can save an average of $101 a month.
  • Electricity consumption: The average home in Guilford doesn't use much energy, and so may not see as many savings on their power bills.

As a result of the cost of solar panels being lower than before as well as several solar incentives, they are a solid investment for many homeowners.

Solar Incentives in Guilford

Switching to solar power has plenty of wonderful benefits. Not only can it help protect the Earth, but you can also save a decent amount of money on your installation with various government incentives. No matter what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which lets you claim 30% of how much you paid for your solar installation when you file taxes, lowering the amount of taxes you owe that year. Additionally, there may be some local incentives you can benefit from too. Our article on solar incentives goes over more in-depth information on the incentives you can take advantage of in Guilford.

Environmental Impact of Switching to Solar in Guilford

There are tons of reasons to switch to solar energy, like saving some money on electricity bills and helping to reduce your carbon footprint. But how much can using solar energy instead of traditional energy actually help the environment? Switching to clean energy for electricity rather than relying on nonrenewable energy sources is an effective way to lower carbon dioxide emissions if you're conscious of Guilford's fair level of greenhouse gas emissions. When you go solar, your carbon emissions can be reduced by about 40 pounds every year. Since energy from the sun is renewable and generates electricity without a carbon footprint, installing solar panels is one easy step you can take to help protect the planet.

EcoWatch's Guilford, CT Solar Company Rankings FAQs

Which solar installation company is the best near me?

The top local solar company in Guilford is Earthlight Technologies, with a rating of 4.06 stars.

What are the pros and cons of solar power?

A few of the biggest pros are that it lets you spend less on your electricity bills, it's environmentally friendly, and it gives you a decent return on your investment (ROI). The most notable cons are that solar panels don't produce electricity at night, there is a high upfront cost and solar panels can be an eyesore.

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

Solar panels typically pay for themselves in about 7.3 years, but your solar payback period will depend on your utility costs. The higher your typical power bill, the quicker your solar panel system will recoup your installation costs.

How efficient are solar panels?

Solar panel efficiency is the amount of energy from the sun that is converted into electricity. Most panels today have an efficiency rating of about 15 to 25%. If your panels are more efficient, you'll need fewer of them for your home's energy needs.
