Methodology: How We Ranked the Best Solar Companies in New Haven

EcoWatch's solar experts analyzed each solar company in New Haven 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 New Haven


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 New Haven

For many people considering switching to solar, the decision of which solar company to go with depends on costs.The installation cost is just one important factor you should take into account when looking into installing solar panels.

  • average energy usage: The more electricity your household consumes on average and the greater your current energy bills are, the more benefits you’ll see from switching to solar.
  • Your home's orientation toward the sun: This, and the configuration of your roof, affects affect how much electricity your solar panels can generate.
  • System size and type: Some models are more costly than others, so the one you get can raise or lower your initial investment. Plus, the more solar panels you need to get, the more it'll cost.

What is the top solar panel installation company in New Haven?

The top local solar company in New Haven is SunPower Corporation, with a rating of 4.00 stars.

What are the pros and cons of solar power?

A few of the biggest pros are that it decreases your power bills, it’s good for the environment, and it gives you a significant return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, they cost a lot upfront and solar panels can look clunky on your roof.

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

Solar panels generally pay for themselves in about 9.2 years, but your solar payback period will vary based on your utility costs. The more your typical electricity bill, the faster your solar panel system will pay for itself.

How long do solar panels last?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger level of energy production.
