Pennsylvania solar panels guide 2023

Updated April 14, 2023

As far as solar incentives go, Pennsylvania is lacking quite a bit. With the exception of the waitlisted Philadelphia Solar Rebate program, there are no state, city, or utility-specific rebates offered for residential solar systems. Saving money by going solar in Pennsylvania mainly comes from the combination of the mandatory net metering law and the 30% federal tax credit.

Solar power prices, savings and payback in your part of Pennsylvania

The average cost for an installed residential solar system in Pennsylvania is currently $9,988 after claiming the 30% federal solar tax credit. This is $2.38 per watt. However, there is some variance in solar prices in different parts of the state. The graph below shows the average cost of installed solar systems in your part of the state.

Are solar panels worth it in Pennsylvania

Solar panels have fallen in price by more than 80% in the last ten years. In 2022 they also remain subsidized by the 30% federal tax credit and the net metering law, making them an excellent investment. They offer a return well above the long term average return from both the share market and also property investment.

Another way to look at this question is the levelized amount you will pay for each kWh of power you will use over the next 25 years with and without solar panels. As you can see below the savings are significant.

Pennsylvania solar incentives & tax credits

Federal solar tax credit

The federal solar tax credit is the most significant incentive to install solar panels for homes and businesses in Pennsylvania. Thanks to the Inflation Reduction Act that went into effect in August 2022, homeowners can now get a tax credit of up to 30% when installing solar panels -  a solid increase compared to previous years.

Home and business owners want the largest incentive possible, and it just so happens that this incentive is as high as it can get for the decade!

Net metering

Pennsylvania law requires all electric distribution companies to offer net metering to their customers. If your solar system produces more energy than you use, your utility will pay the full retail rate for all that extra solar energy.

Since Pennsylvania's electricity rates are so high, net metering can save homeowners a pretty penny.


Pennsylvania alternative energy credits

The Alternative Energy Portfolio Standard Act of 2004 mandates that all electric companies and suppliers must obtain 18% of their electricity from clean energy sources by 2021; 0.5% must be derived from solar. At this time, no further updates have been made to this act. 

Companies must purchase alternative energy credits (AECs) to meet their quota. One credit is equal to 1 megawatt-hour of renewable energy. As of March 2023, the bid pricing has reached $47 per AEC. These prices are subject to change based on the current market. Pennsylvania homeowners can make back their money with solar by generating these AECs and selling them to the utilities. 

Philadelphia Solar Rebate

The Philadelphia Solar Rebate incentive program was introduced in 2019 to encourage homeowners to install photovoltaic systems on their homes. This one-time incentive offers $0.20 per watt for residential projects and $0.10 for commercial projects. Rebates are capped at $100,000 and reserve 10% of the funds for low and moderate-income households.

The program is currently closed to do budget cuts caused by COVID-19. However, they are still accepting applications to place applicants on a waiting list for when funding is restored.

Is it better to lease or buy solar panels in Pennsylvania

You will save most money by buying your solar system rather than leasing it. Read more about the pros and cons of leasing vs buying solar.

How long do solar panels last?

Minimum of 25 years but generally 30 or more

How do solar panels work on a home?

Solar panels power your house when they can but your home uses the utility company for power at other times. In 2023 "solar systems with battery storage" are becoming more popular. These are known as hybrid systems.

How do solar panels work?

Grid-tied solar system

A grid-tied system is the most common type of solar system. It has no solar battery for backup power and utilizes net metering to maximize savings. Solar panels are mounted on your roof then wired together, and the power generated flows into an inverter where direct current (DC) electricity is converted into alternating current (AC) electricity. This electricity is either used by your home or is exported to the utility grid.

Hybrid solar system

In hybrid solar systems, rooftop solar panels are connected to both a solar battery and the electric grid. The solar electricity generated by your panels that your home does not use is stored in the battery instead of being sent to the grid, which reduces your reliance on the utility while also providing backup power when needed. Battery storage is still expensive but you may be able to reduce costs by using state incentives.

Off-grid solar system

Off-grid solar systems are not connected to the grid at all, so all of your energy needs must be met by the sun. There is no utility to fall back on. The solar installation needs to power your home not only during the day, but after dark as well, so many solar panels and a large battery system are required. These systems are often expensive and don’t make sense for homes that have access to the grid.

Do solar panels require regular maintenance?

No, but cleaning them can improve power generation if they are dirty.

Will residential solar power system cost fall in Pennsylvania in 2023?

Given this environment, and the effect of import tariffs placed on solar panels by the Trump administration during 2018, it is hard to see that solar power system prices in Pennsylvania will fall during 2023.

How much electricity do solar panel systems generate in Pennsylvania?

Depending on the location, solar panels will generate different amounts of electricity.

A solar system that is installed on a south-facing 27-degree pitch roof Pennsylvania will generate 1,254kWh of peak DC (direct current) capacity per year per 1kW in Pennsylvania.

Enter your details into the solar panel calculator to see how your location, roof tilt, and roof direction impacts solar panel production.

What are the pros and cons of installing solar panels in Pennsylvania?

The main advantage of installing solar panels is that Pennsylvania's power prices are above the national average, so the return on investment of solar panels is among the best in the U.S. 

In Pennsylvania, the law mandates net metering, which requires retail electricity sellers to provide their customers with a credit equal to the retail electricity rate for the excess generation their systems create. In addition, the federal solar tax credit has reached 30%, which is higher compared to recent years.

The biggest disadvantage of installing solar panels in Pennsylvania is the state’s lack of state and utility solar incentives and rebates. Also, the state does not require a property tax or sales tax exemption on solar energy equipment as many other states do. Pennsylvania also receives less sunshine than some other states, like Arizona or New Mexico. This means a solar system installed here will produce a little less than in sunnier states.
