Methodology: How We Ranked the Best Solar Companies in Harleysville
EcoWatch's solar experts analyzed each solar company in Harleysville 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 Harleysville
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 Harleysville
For many people, the decision of which solar company to choose comes down to total costs.Some key factors that influence the cost of installing a solar panel system on your home and how much it could save you over time are:
- Your income and budget: This determines what model of solar panels you can buy.
- How much power your home consumes: Households that use plenty of power each month may need more solar panels and, consequently, be more expensive, but will also enjoy more savings over time.
- Incentives: The federal solar investment tax credit, which can save you some money, allows you to deduct 0 of the cost of your solar system installation from your taxes. Plus, not including incentives, you can save about $15,000 over 20 years on your energy bills.
- How much sunlight your roof gets: If your roof doesn’t see much direct sunlight, your solar panel system won’t be able to produce as much energy, which will leave you with lower savings on electric bills than someone with a roof that gets a lot of sunlight.
Thanks to solar panels decreasing in cost as well as various solar incentives, they are a solid investment for many homeowners.

Environmental Impact of Switching to Solar in Harleysville
There are a few important reasons why people are considering solar energy: to help their wallet and the environment.But how much can installing solar panels actually help the environment? Adopting solar power is an impactful choice for the environment, due to the fact that the greatest source of greenhouse gas emissions in the U.S. is from burning fossil fuels for electricity, heat, and transportation – all of which can be powered by solar instead.Since solar panels don’t release greenhouse gas emissions into the atmosphere when producing electricity, they’re a good swap for traditional energy sources.

You can also help preserve the environment, which some would argue is priceless.
