Pennsylvania Solar Panels

Pennsylvania’s Solar Renewable Energy Credit (SREC) program is part of the state’s Alternative Energy Portfolio Standard (AEPS). Every time your solar system generates 1,000 kilowatt-hours (1 MWh) of electricity, you earn one SREC. A typical 6 kW residential system produces roughly 9–10 SRECs per year, which can translate to approximately $225–$400 in annual income based on current market prices of $25–$40 per SREC.

To participate, you must register your solar system with the Pennsylvania Public Utility Commission (PUC) through the Alternative Energy Credit Administration and list it on the Generation Attribute Tracking System (GATS) trading platform. Once registered, you can sell your SRECs through brokers such as SRECTrade or Flett Exchange, either at spot market prices or through fixed-rate contracts lasting 3–5 years. Note that SRECs have a useful life of three years, so credits must be sold within that window before they expire.

Important eligibility details: only Pennsylvania-sited solar systems qualify for PA SRECs (out-of-state systems are not eligible), and SRECs belong to the system owner — if you lease your panels, the leasing company typically retains the SREC rights. Solar-plus-battery systems also qualify, as long as the solar generation is metered separately.

Pennsylvania law requires all investor-owned electric utilities — including PECO, PPL Electric, Duquesne Light, Met-Ed, Penelec, Penn Power, and West Penn Power — to offer 1-to-1 net metering to residential solar customers. Under this policy, every kilowatt-hour your solar system sends to the grid offsets one kilowatt-hour you consume from the grid, effectively crediting you at the full retail electricity rate (approximately $0.21/kWh). Residential systems up to 50 kW are eligible, and nonresidential systems up to 3,000 kW can also participate.

Excess credits roll over month to month throughout the year. At the end of the net metering year (typically May 31), any remaining surplus kilowatt-hours are settled at the full retail value in most utility territories. This annual true-up ensures you receive fair compensation for all the solar energy you contribute to the grid over the course of the year.

One important note for PPL Electric customers: PPL has proposed tariff changes that could alter net metering terms around July 2026. Homeowners who install solar before any approved changes take effect may be grandfathered into the current 1-to-1 retail rate policy. Contact your specific utility or the PA PUC directly to confirm the latest net metering rules in your service territory.

While the federal residential solar tax credit (Section 25D) expired on December 31, 2025, the commercial Investment Tax Credit under Section 48E remains active at 30% of system costs. This credit applies to solar systems owned by third-party companies — meaning it is directly relevant to Pennsylvania homeowners who choose to go solar through a lease or power purchase agreement (PPA) rather than purchasing a system outright.

In a lease or PPA arrangement, the solar company retains ownership of the panels installed on your roof and claims the 30% federal ITC. The financial benefit is then passed through to you indirectly in the form of lower monthly lease payments or a reduced per-kilowatt-hour PPA rate compared to what the company would otherwise charge. This makes leases and PPAs a potentially attractive option for homeowners who cannot benefit from a direct tax credit.

Keep in mind that with a lease or PPA, you do not own the solar system, which means you also do not own the SRECs generated by the panels — those typically belong to the third-party company. Carefully review your contract terms to understand how savings are structured and whether the arrangement makes financial sense for your household over the full contract term (often 20–25 years).

The Pennsylvania Alternative Energy Portfolio Standards Act (Act 213 of 2004) is the foundational policy that drives the value of Solar Renewable Energy Credits (SRECs) in the state. Under AEPS, electric distribution companies (EDCs) and electric generation suppliers (EGSs) are required to include a specific percentage of electricity from alternative energy resources — including solar — in the power they sell to Pennsylvania customers. Utilities that fail to meet these requirements must pay an Alternative Compliance Payment (ACP), which effectively sets a price ceiling for SRECs.

The AEPS includes a solar-specific carve-out within its Tier I requirements, meaning utilities must source a defined portion of their electricity specifically from solar photovoltaic systems. This solar carve-out is what creates consistent buyer demand for PA SRECs and keeps the market active. Compliance is tracked through the PennAEPS system and the Generation Attribute Tracking System (GATS).

Note that Pennsylvania’s original RPS goal expired in 2021 and a new long-term target has not yet been legislatively established. While the SREC market remains active, the absence of an updated RPS goal introduces some long-term uncertainty about future SREC prices and demand. Homeowners should factor this into their financial projections when evaluating the value of SRECs over a 20–25 year system lifetime.

Pennsylvania’s Sustainable Energy Funds (SEF) were established as part of electric utility deregulation and have provided over $20 million in low-interest loans and nearly $2 million in grant funding to support clean energy projects across the state. These funds are specifically designed to help close financing gaps that remain after other incentives — such as SRECs and net metering savings — have been applied, making solar and battery storage projects more financially accessible.

SEF programs are available to customers in specific utility territories, primarily PPL Electric and FirstEnergy subsidiaries (Met-Ed, Penelec, Penn Power, and West Penn Power). Eligible projects can include residential and commercial solar installations, as well as solar-plus-battery storage systems. Loan terms and grant amounts vary by program and project type, so applicants should contact their regional SEF administrator for current availability and eligibility requirements.

Because SEF funding is limited and allocated on a rolling basis, homeowners interested in this program are encouraged to apply early. SEF financing can be stacked with other incentives such as SRECs and net metering credits to improve the overall economics of a solar installation, particularly for projects in rural or underserved communities within eligible utility territories.

The USDA Rural Energy for America Program (REAP) is a federal grant and loan guarantee program that supports renewable energy installations — including solar panels and solar-plus-battery storage systems — for agricultural producers and rural small businesses in Pennsylvania. REAP grants can cover up to 50% of eligible project costs, dramatically reducing the upfront investment required and potentially enabling payback periods as short as one year for qualifying projects.

To be eligible, applicants must be either an agricultural producer (farmer, rancher, or other ag operation) or a small business located in a rural area as defined by USDA guidelines. The property where the solar system is installed must be used for agricultural or business purposes. Both new solar installations and upgrades to existing systems may qualify, and solar-plus-battery storage projects are eligible as long as the storage component is paired with the renewable energy system.

REAP funding is competitive and awarded through application cycles, so Pennsylvania rural businesses and farms should apply as early as possible. In many rural Pennsylvania solar projects, REAP participation is the factor that makes battery storage financially viable. Contact your local USDA Rural Development office in Pennsylvania for current funding availability, application deadlines, and assistance with the application process.

The Pennsylvania Solar Energy Program (SEP) is a state-administered financing program that provides loans to support solar energy installations across Pennsylvania. The program is jointly administered by the Department of Community and Economic Development (DCED) and the Department of Environmental Protection (DEP). Loans for solar energy generation or distribution projects are capped at $5 million or $3.00 per watt of installed capacity, whichever is less, making it particularly useful for larger commercial or community solar projects.

SEP loans are designed to fill financing gaps for solar projects that may not qualify for or fully benefit from other incentive programs. By offering below-market loan rates, the program helps make solar installations financially viable for a broader range of Pennsylvania property owners, businesses, and organizations. Eligible projects must be located within Pennsylvania and must involve the generation or distribution of solar energy.

Homeowners and businesses interested in the SEP should contact the DCED directly to confirm current loan terms, interest rates, and application requirements, as program details may be updated periodically. The SEP can be combined with other incentives such as SRECs and net metering to further improve the financial return on a solar investment.

The Homeowners Energy Efficiency Loan Program (HEELP), administered by the Pennsylvania Housing Finance Agency (PHFA), provides low-cost financing to help Pennsylvania homeowners make energy-related improvements to their homes. Loans range from $1,000 to $10,000 at a fixed 1% annual interest rate, repaid over 10 years with no prepayment penalties. While HEELP is not exclusively a solar program, it can be used to finance electrical panel upgrades, roof repairs, or wiring improvements that are necessary prerequisites for a solar installation.

HEELP is particularly valuable when bundled with a solar project, as many homes require electrical system upgrades before solar panels can be safely and legally installed. By financing these ancillary costs through HEELP at just 1% interest, homeowners can reduce the total out-of-pocket cost of going solar without rolling these expenses into a higher-rate solar loan. The program is available statewide to eligible Pennsylvania homeowners.

Eligibility requirements apply, and not all homeowners will qualify. HEELP can be stacked with other Pennsylvania solar incentives, including SRECs and net metering credits, to maximize overall savings. Contact the Pennsylvania Housing Finance Agency directly for current eligibility criteria, income limits, and application instructions.

Residential customers of FirstEnergy’s Pennsylvania subsidiaries — Met-Ed, Penelec, Penn Power, and West Penn Power — can receive a $500 rebate when they install a new solar water heating system on their home. This rebate is offered through FirstEnergy’s Act 129 energy efficiency program and is available to active residential customers in good standing within these utility service territories.

To qualify, the solar water heating equipment must be ENERGY STAR certified. Solar water heaters use the sun’s energy to heat water for household use, reducing the amount of electricity or gas needed to power a conventional water heater. This can meaningfully lower monthly utility bills, and the $500 rebate helps offset the upfront installation cost.

This rebate is separate from solar photovoltaic (electricity-generating) incentives and applies specifically to solar thermal water heating systems. Homeowners interested in this rebate should verify current availability and submit their application through FirstEnergy’s Pennsylvania rebate portal, as Act 129 Phase IV rebates are active through May 31, 2026, and program terms may change under Phase V.
