Methodology: How We Ranked the Best Solar Companies in Cornwall

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


Below are some the criteria we examined specifically for New York 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 Cornwall

We get that for most homeowners, the decision to invest in solar rests on installation costs.There are a few factors you should consider when determining how much it will cost and how much you can save, including:

  • Choice of solar panels: The type of solar panels you get will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
  • Where your home is: This affects how much sunlight your roof receives, which helps determine how many panels you need.
  • Your current electricity bills: Solar panels can significantly lower, or entirely get rid of, your utility bills. In Cornwall, you can save an average of $1,263 a month.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 0 of your overall installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Not including incentives, you can save an average of $21,000 over 20 years with your solar panels, too.

Solar is a valuable investment for most homeowners. You can make your own power instead of paying for it from a utility company and make use of solar tax credits and rebates, all while helping preserve the Earth.

Solar Incentives in Cornwall

There are many reasons why going solar is a great investment. One of them involves some government incentives you can take advantage of.On top of the federal tax credit incentive, there are also some local benefits, which in most cases, stack with the federal incentive, so you get to save even more. Our article on solar incentives goes over more detailed information on the incentives you can take advantage of in Cornwall.

Environmental Impact of Switching to Solar in Cornwall

Many want to do their part for the planet, which in many cases is the prime reason for installing solar panels.Something many might be thinking about is how much can they really help protect the environment by switching to solar power anyway? In a place like Cornwall where commute times can be very long, going solar can help help reduce the carbon footprint of driving a lot.Because solar panels don’t release carbon dioxide emissions into the atmosphere when producing electricity, they’re a good trade for nonrenewable energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 20 pounds each year. If you care about the environment, you’ll most likely find that there are many benefits of adopting solar energy other than just saving money on bills. You can also help preserve the environment, which some would argue is worth more.
