Methodology: How We Ranked the Best Solar Companies in Willistown

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


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.

Environmental Impact of Switching to Solar in Willistown

If you’re thinking of adding solar panels to your home, one of the primary reasons why may be to lower your carbon footprint.But how much can switching to solar actually affect the environment? One thing you should consider is your overall carbon footprint. For example, if you have a long commute time and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions.Because solar panels don’t release CO2 emissions into the atmosphere when creating electricity, they’re a good swap for nonrenewable energy sources. In fact, you could look forward to lowering your carbon dioxide emissions by about 60 pounds each year. For those who are concerned about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.
