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

While solar panels can save you money on utility bills over time, it's important to take into consideration the upfront costs. The installation cost is just one important factor you should keep in mind when looking into getting solar panels. How much it'll cost and how much you can save depend on things including:

  • Choice of solar panels: The type of solar panels you need will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also save you more money over the lifetime of your system. If you don't need to maximize efficiency, you can go with a higher number of more affordable panels.
  • The cost of electricity in your area: If your local electricity rates are quite high, there's a good chance you'll end up with a higher return on your investment in a solar panel system. In Downingtown, you can save an average of $89 a month on your electricity bills.
  • Incentives: Those who purchase and install a solar system this year can save 30% of their total solar spend by using the federal solar investment tax credit. You can also save about $15,000 on your utility bills over 20 years excluding incentives.
  • The amount of sunlight your area gets: Thanks to Downingtown's high amount of average daily sunlight, you should be able to save a decent amount on your power bills.

Solar is a fruitful investment for most homeowners. You can generate your own energy instead of paying for it from a utility company and benefit from solar tax credits and rebates, all while helping preserve the Earth.

Solar Incentives in Downingtown

Although solar power is typically a large investment, it can save you a lot of money over time due to smaller power bills and government incentives. When you install a solar panel system on your home, you become eligible to claim the federal tax credit, or ITC. This credit currently reduces your tax bill by 30% of the cost of your solar panels. In addition, there may often be some regional incentives that you can use to further cut back on the cost of solar of solar panels. For comprehensive information about incentives that apply to you, check out our article on solar incentives.

Environmental Impact of Switching to Solar in Downingtown

Going solar can have a meaningful impact on the environment. But how much can using solar energy instead of traditional energy actually affect the environment? One thing to consider is your overall carbon footprint. For example, if you spend a lot of time in the car and have an electric vehicle, you can install solar panels on your home to power your EV and therefore help offset your carbon emissions. If you go solar, your carbon footprint can be lowered by about 60 pounds every year. If you want to do what you can for the environment, you'll most likely get that there are many advantages to adopting solar energy other than just saving money on bills. You can also help protect the environment, which some would argue is worth more.

EcoWatch's Downingtown, PA Solar Company Rankings FAQs

Which solar panel installer is the best near me?

In Downingtown, Eferon Solar Solutions is the top local solar company. Our team of experts rates it 5.00 stars, so it's a great choice if you're looking to install solar panels on your roof.

What are the best and worst things about solar power?

The main advantages of solar power are that it can lower or, in some cases, entirely cut your electricity bills, improve your home's value and lower your carbon footprint. The main disadvantages are that solar panels can be costly to install, you may not see as many savings if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.

Are solar panels worth it?

Solar panels call for a considerable upfront investment that will cost you several thousands of dollars, but whether or not solar panels are worth it depends on a collection of factors like how much you pay for electricity and the amount of direct sunlight your roof gets.

How often do solar panels have to be replaced?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is how much energy they produce will have decreased by about 0.8% each year since installing them. You can choose to replace them after having them for that long or you can keep using them at a lower efficiency after that time.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
