Solar energy is expensive, costing anywhere from $16,000 to $21,000*. Choosing one of the best solar companies can help you feel more confident that you’re making a long-lasting and worthwhile investment.

To help you decide, we at the Home Media reviews team have researched the best solar installers in Pennsylvania and provided our top recommendations. Our rankings are based on customer service, warranty coverage, financing options, and a range of other factors discussed below.

* Data from the Solar Energy Industries Association (SEIA)

Based on our methodology and ranking system, these are the best solar companies in Pennsylvania:

​​+ Includes system monitoring through an interactive app

​​+ Offers customer rewards through Momentum Family Rebate Program

​​+ Provides full service, from consultation to installation

Momentum Solar offers a range of solar panels , making it easy for customers to personalize their systems. The company partners with Enphase to offer solar battery storage and also has options for electric vehicle (EV) chargers, inverters and other solar products.

Momentum includes a 25-year equipment warranty and a 25-year workmanship warranty. These warranties cover products and labor, offering comprehensive protection.

Momentum Solar also offers educational resources through its blog, regular energy audits and an interactive mobile app to track system performance.

Payment options: Momentum offers four financing options: full purchase, solar lease, solar loan and power purchase agreement (PPA). Maintenance is included for solar leases and PPAs; it’s an add-on for full purchases and solar loans.

Solar loans operate similarly to a home or auto loan, allowing you to pay off your system in installments over time. However, you’ll pay more in total than you would with a full purchase due to interest rates.

Solar leases involve paying a fixed monthly rate to use solar power without committing to owning your system. PPAs allow you to pay a fluctuating rate based on the energy you use, similar to an electricity bill. Both options disqualify you from taking advantage of cost-saving solar incentives because your provider retains ownership of the system.

We called companies and spoke with representatives to understand their products, services and solar installation processes. We also reviewed each company’s product, production and workmanship guarantees in detail, and we closely examined customer reviews to understand the customer service experience with each provider.

All company data is monitored on an ongoing basis to keep rankings and information up to date.
