Methodology: How We Ranked the Best Solar Companies in King of Prussia

EcoWatch's solar experts analyzed each solar company in King of Prussia 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 King of Prussia


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 King of Prussia

For many readers, the decision of which solar installer to hire depends on total costs.Some main factors that influence how much it will cost to install a solar panel system on your home and how much money you could save over time are:

  • Average daily sunlight: Since King of Prussia gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which affects how much your electricity bills will be.
  • Incentives: One thing that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save on your utility bills, which can result in an average of $15,000 of savings over 20 years.
  • How much energy your home consumes: Homes that use plenty of electricity each month may require more solar panels and, therefore, more upfront cost, but will also enjoy more savings over time.
  • System size and type: Some models are more expensive than others, so the one you decide on can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.

Due to solar panels now being cheaper than ever as well as several solar incentives, they are a solid investment for most homeowners.

Environmental Impact of Switching to Solar in King of Prussia

Lots of people want to do their part for the planet, which for many is the primary motivation to install solar panels.You may be wondering – how much does making the switch help the planet anyway? If your home uses lots of energy, you can help the environment even more by switching to solar power.Since solar panels don’t release carbon dioxide emissions into the atmosphere when producing electricity, they’re a good substitute for nonrenewable energy sources. In fact, you could reduce your carbon dioxide emissions by about 50 pounds each year. As you can see, investing in solar has so many other benefits outside of saving money. One of the main ones is that you can help save the planet too.
