Going solar in Pennsylvania

Pennsylvania’s above-average electricity prices and solid net metering and SREC programs make solar panels a good investment for pretty much anyone in the Keystone State. 

Factor in the federal solar tax credit, and Pennsylvanians can cut the cost of solar by thousands of dollars, speeding up their payback periods and increasing the value of their investments. 

Here's our guide to going solar in Pennsylvania.


How much do solar panels cost in Pennsylvania?

Solar panels will save you a lot of money over time, but the upfront costs aren't cheap. The average Pennsylvania homeowner needs a 12.13 kW solar panel system to cover their electricity needs, which comes out to $34,639 before incentives. Prices range from $29,443 to $39,835, but after the federal tax credit, that drops by 30%. 

While this may sound high, it will pay off in Pennsylvania. That's why over 35,000 Pennsylvania homeowners have used EnergySage to receive and compare quotes for solar installations. You can expect to earn back your initial solar investment through electricity savings in about 7.49 years, while most systems last at least 25 years. You'll often see this number referenced as your solar payback period.

There are a few ways to finance your solar panel system so you don't have to provide all that money upfront. 

  • Cash purchase: You'll own the system and pay for it upfront. This provides the best long-term savings. 

  • Solar loan: Allows you to retain ownership of your system, while owing little to no money upfront. Solar loans aren't all created equal: If you have access to subsidized clean energy loans through local incentive programs, that's usually your best bet. A home equity loan or a personal loan are often your next best options – private solar loans typically come with higher interest rates or upfront fees.

  • Solar lease or power purchase agreement (PPA): A third-party company owns your system and either leases you the solar panels (solar lease) or allows you to purchase the electricity they generate (PPA). These generally provide the lowest savings and generate the most negative press about solar. If you choose this financing option, read the fine print: You can get trapped in them for longer than you'd like.

What are the best solar rebates and incentives in Pennsylvania?

Incentives help bring solar's price tag down considerably in Pennsylvania. Here are the major ones to know about:

Average savings in Pennsylvania

Residential Clean Energy Tax Credit, formerly the federal investment tax credit (ITC)


Lowers your solar panel system's cost by 30%

Solar Alternative Energy Credits, also known as solar renewable energy credits (SRECs)


Allows you to generate and sell SRECs to utilities

High Performance Building Program (HPB)

$1,479 (for grants)

Provides loans and grants for the construction or renovation of high performance building projects

Is net metering available in Pennsylvania?

In some states, you'll earn bill credits from your utility company when your solar panel system generates excess electricity and sends it to the grid. This incentive is known as net metering—basically a solar buyback program—and makes it so you will owe very little, or even nothing, on your electric bills with solar panels. 

Utility companies in Pennsylvania offer solid net metering programs. You’ll be credited at the retail rate of electricity for every kWh you contribute to the grid until your generation is equal to your utility demand. If you send more electricity to the grid than you consume, you’ll be credited at the “price to compare” for that excess generation—a little less than the retail rate.

Equipment quality

Each year, solar panels get more and more efficient—that is, they produce more power per square foot. As of 2024, the most popular solar panels can produce about 400 watts of electricity when they’re in full sunlight. If you want to make the most of your roof’s solar potential, get panels with at least that much power output.  

You should also make sure to select a solar inverter setup that makes sense for your roof’s layout. 

And if you want or need a solar battery, be sure to pick one that can integrate cleanly with that inverter. 

Premium equipment can come with a high price tag, but it will often save you more money in the long run. The best equipment tends to have the best warranty terms, often guaranteed to 25 years (sometimes even 40!), so you’re covered in case you need repairs or replacements. The highest-quality panels also degrade more slowly, so they’ll maintain more of their power output further into the future.
