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 Pennsylvania 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

For a lot of homeowners, whether or not to invest in a solar energy system boils down to the cost.There are several factors you should take into consideration when determining the overall cost and how much you can save, such as:

  • The kind of solar panels you can afford: This depends on how much you’re willing to invest upfront.
  • Your location: This affects how much sunlight your roof gets, which helps determine how many panels you need.
  • 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 can help you save even more. Not including incentives, you can save an average of $14,000 over the first 20 years with your system, too.
  • How much power your household needs: If your household regularly uses a lot of energy, you'll benefit more from going solar.

Environmental Impact of Switching to Solar in Cornwall

Installing solar panels can have a meaningful effect on the environment.Something many homeowners might be wondering about is how much can they really help save the environment by going solar anyway? The average person has a sizable 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 think about what to do. Going solar is a practical thing you can do to help.Because solar panels don’t release greenhouse gas emissions into the atmosphere when creating electricity, they’re a good swap for traditional energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. Since solar energy is plentiful and produces electricity without releasing carbon emissions, installing solar panels is one easy step you can take to help protect the planet.
