Methodology: How We Ranked the Best Solar Companies in Willow Street

EcoWatch's solar experts analyzed each solar company in Willow Street 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 Willow Street


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 Willow Street

We get that for most homeowners, the choice to invest in solar hinges on installation costs.The installation cost is just one important factor you should consider when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • Energy consumption: Installing a solar system may be an expensive investment for homes that don’t use a good amount of energy each month.
  • The model of solar panels you can afford: This hinges on what your budget is.
  • Incentives: One thing that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that’s equal to a percentage of the project cost. You can also save money on your utility bills, which can lead to an average of $14,000 of savings over 20 years.
  • How much energy costs for you: If your local utility rates are quite high, there's a good chance you'll have a higher return on your investment in a solar system. In Willow Street, you can save an average of $1,346 a month on your electricity bills.

Solar is a profitable investment for most homeowners. You can make your own electricity instead of paying for it from a utility company and make use of solar incentives and rebates, all while helping the Earth.

Environmental Impact of Switching to Solar in Willow Street

Going solar can have a positive effect on the environment.But how much can switching to solar actually affect the environment? One thing to consider is your overall carbon footprint.

In Willow Street, you can reduce your carbon footprint by 50 pounds a year with solar panels. The great things about solar power are abundant — just like solar power is! That's why so many people have been happy with making the switch to solar.
