Methodology: How We Ranked the Best Solar Companies in Downingtown

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


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 Downingtown

When choosing a solar company, most homeowners or business owners care about the costs above all.The overall price and potential savings vary depending on a few important factors such as:

  • System size and type: Some models are more costly than others, so the one you get can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
  • Energy consumption: Installing solar panels may be a high-cost option for households that don’t consume a good amount of energy per month.
  • Incentives: The federal solar investment tax credit currently lets you decrease your taxes by 0 of the project cost. Your state and city may also have incentives and rebates that you can benefit from. In addition, you can save about $15,000 over 20 years on your utility bills, before factoring in incentives.
  • Your current power bills: Solar panels can noticeably reduce, or totally eradicate, your utility bills. In Downingtown, you can save an average of $1,290 a month.

Even though a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on several factors, such as the size of your solar panel system and your energy consumption.
