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

When picking a solar company, most homeowners or business owners worry about the costs the most.The installation cost is just one important factor you should take into account when looking into getting solar panels. How much it'll cost and how much you can save depend on things including:

  • System size and type: Some models are more expensive than others, so the one you want to get can raise or lower your initial investment. Plus, the more solar panels you need to get, the more it'll cost.
  • Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 0 of the project cost. Your state and city may also have various incentives that you can take advantage of. Plus, you can save about $25,000 over 20 years on your utility bills, not including incentives.
  • How much electricity your home consumes: Homes that consume lots of electricity each month may call for more solar panels and, as a result, be more expensive, but will also benefit more over time.
  • The amount of sunlight your roof gets: Because of Preston’s high amount of average daily sunlight, you should be able to save a decent amount on your electricity bills.

Although a solar panel system costs a good chunk of money upfront, it can save you much more in the long term. The question of how much, though, depends on several factors, including the size of your solar panel system and incentives.

Solar Incentives in Preston

One of the benefits of installing a solar panel system is receiving government incentives.There are several federal, state and local rebates and tax credits that let you earn a decent amount of money back after installing a solar panel system. In our article on solar incentives, you can see the incentives you qualify for in Preston.

Environmental Impact of Switching to Solar in Preston

An important reason so many homeowners are considering going solar is to help lower their environmental impact.But how much can switching to solar actually affect the environment? A key thing to be mindful of is your overall carbon footprint. For example, if your commute is very long, your footprint may be larger, so adopting solar power for your house can help offset that.Although solar panel production emits carbon dioxide, the panels make up for it by significantly lowering the amount of CO2 you would have released if you still used traditional energy. In Preston, you can reduce your carbon footprint by 40 pounds a year with solar panels. The good things about solar power are infinite — just like solar power is! That's why so many Preston residents have been happy with committing to solar.

What are the advantages and disadvantages of solar power?

A few of the biggest pros are that it lets you spend less on your power bills, it’s a sustainable source of energy, and it can give you a decent return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, the startup costs are high and solar panels can look clunky on your roof.

How long does it take for solar to pay for itself?

The average payback period for solar panel installation is about 9.9 years, but the exact period varies by the cost of electricity where you are, incentives and net metering programs.

When is the best time of year to install solar panels?

You can install solar panels whenever it's convenient for you, but consider doing it in the winter when the demand is less. With fewer homeowners contracting installers, you could potentially see quicker installation times and more savings.
