Methodology: How We Ranked the Best Solar Companies in Preston
EcoWatch's solar experts analyzed each solar company in Preston 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 Preston
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 Preston
For many readers, the decision of which solar installer to hire depends on total costs. There are quite a few factors you should consider when determining the overall cost and how much you can save, including:
- Electricity consumption: The average household in Preston doesn't use much energy, and consequently may not see as many savings on their power bills.
- Choice of solar panels: The kind of solar panels you need will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If you don't need to maximize efficiency, you can opt for a higher number of more affordable panels.
- Your current power bills: Solar panels can noticeably decrease, or entirely eliminate, your utility bills. In Preston, you can save an average of $100 a month.
- Incentives: The federal solar investment tax credit, which everyone qualifies 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.
So is a solar panel system worth it? Whether you're trying to decrease your electricity costs, carbon emissions or both, solar panels are a solid investment for many Preston homeowners.

You qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your a solar panel system. You can also potentially use the ITC with other local incentives. Our article on solar incentives has more in-depth information on the incentives you can find in Preston.
Environmental Impact of Switching to Solar in Preston
One of the reasons so many people are thinking of installing solar panels is to help reduce their environmental impact. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Preston, though. The average person has a substantial carbon footprint. Between their car, which produces over 10,000 pounds of carbon dioxide emissions each year, and energy for their home, it can be overwhelming to figure out what to do. Using solar power is one of the easiest things you can do to help. Although making solar panels releases carbon dioxide emissions, the panels make up for it by greatly decreasing the amount of CO2 you would have been responsible for if you still used traditional energy. In Preston, you can reduce your carbon footprint by 40 pounds a year with solar panels. Since solar energy is renewable and produces electricity without free from carbon dioxide emissions, installing solar panels is one easy step you can take to help protect the planet.

EcoWatch's Preston, CT Solar Company Rankings FAQs
Which solar installation company is the best near me?
The highest-rated local solar company in Preston is Earthlight Technologies, with a rating of 4.06 stars.
What is the negative environmental impact of making solar panels?
Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to recycle 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.
Is it worth putting solar panels on my roof?
Solar panels can be a great investment for lots of homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get enough sunlight or your electricity bills are already fairly low, solar panels might not be for you.
What is solar panel capacity and how much do I need for my house?
Solar panel capacity is rated based on the amount of power they generate under standard testing conditions. Since each panel can usually produce about 250 to 400 watts per hour, the average house will need 20 to 35 panels.
