Commercial Solar Incentives in Pennsylvania - Guide for Businesses
Commercial solar incentives in Pennsylvania can cover a large share of the cost of a solar panel system before you even count the long-term savings on your electricity bill. If your company looked at solar in the past and held off because of the upfront cost, the math has changed.
Between federal tax credits, state financing programs, and updated net metering rules, going solar now carries less financial risk than it did even two years ago.
TerraSol Energies prepares detailed financial solar reports for businesses across Pennsylvania, New Jersey, and Delaware.
This guide breaks down every program a Pennsylvania business should know about in 2026, what changed under the One Big Beautiful Bill Act (OBBBA), and how to combine these Pennsylvania solar incentives into one financing plan.
TL;DR
- SRECs and net metering add ongoing revenue and savings on top of that: sell credits earned per 1,000 kWh generated, and get full retail credit for excess energy sent to the grid.
- PEDA grants, C-PACE, and USDA REAP can cover much of the upfront cost through low-interest financing or no-money-down options, especially for rural businesses and farms.
- Smaller local programs (PA Sunshine, Philadelphia’s rebate, HEELP) are mostly inactive or residential-focused. The real savings for PA businesses come from stacking the federal incentives above.
Commercial Solar Incentives in Pennsylvania: The Full List for 2026
Here is the current list of commercial solar incentives in Pennsylvania, covering federal tax incentives, state financing, and utility programs:
- Federal solar tax credit (30% ITC)
- 100% bonus depreciation
- Pennsylvania Solar Renewable Energy Credits (SRECs)
- Net metering
- PEDA grants and financing
- C-PACE financing
- USDA REAP grants for farms and rural businesses
- Local and utility rebate programs
- Nonprofit direct pay under the IRS elective pay rules
Each one is covered below, with notes on eligibility and current deadlines.
1. Federal Solar Tax Credit for Businesses (30% ITC)
The federal tax credit for solar dropped off the table for homeowners. The Residential Clean Energy Credit (Section 25D) expired on December 31, 2025. But the commercial federal tax credit did not go away.
Under Section 48E of the tax code, businesses that own a solar system can still claim a 30% federal tax incentive on the cost of the project, according to the Internal Revenue Service. That makes 2026 one of the better years to be a business owner rather than a homeowner shopping for solar.
A few details matter for Pennsylvania businesses:
- Projects must begin construction by July 4, 2026, to lock in the full 30% rate under current safe harbor rules. Projects starting after that date face a tighter deadline to be placed in service.
- An Energy Community Adder adds 10 percentage points if your facility sits in a qualifying area (former coal or fossil fuel region, brownfield site, or high-unemployment census tract).
- A Domestic Content Adder adds another 10 percentage points if you use a set share of U.S.-manufactured equipment.
- Stacked together, some projects can reach a 40–50% effective tax credit.
If you want to see how this tax credit plays out alongside financing instead of a cash purchase, we walk through the numbers in our piece on stacking incentives with commercial solar financing.
2. 100% Bonus Depreciation
This is the incentive that changed the most since 2023. Bonus depreciation had been phasing down toward zero under the old tax rules.
The OBBBA, signed into law in July 2025, restored 100% bonus depreciation for solar equipment placed in service after January 19, 2025, and made it permanent going forward, per the Solar Energy Industries Association.
In plain terms: your business can deduct the full depreciable cost of a solar system in year one instead of spreading it over five years. Combine that with the 30% federal tax credit, and many businesses recover close to half of their total project cost through tax benefits alone, before a single kilowatt-hour of energy savings.
We saw this play out at full scale on a 1 MW commercial solar project that used these same incentives to make a 70,000-square-foot facility nearly energy independent.
3. Pennsylvania Solar Renewable Energy Credits (SRECs)
Pennsylvania's Solar Renewable Energy Credit program — sometimes called solar renewable energy certificates or SRECs — pays you for the electricity your solar system generates, separate from the savings on your electric bill.
Here's how it works:
- Your system earns one SREC for every 1,000 kWh of electricity generated.
- A typical 6 kW commercial-scale system generates roughly 8 SRECs per year.
- SRECs in Pennsylvania have recently sold for around $30 to $50 each, though prices move with market conditions and supply.
- You can sell SRECs to utility companies or on the open market to meet Pennsylvania's renewable energy standards under the Alternative Energy Portfolio Standards Act.
- Payment goes straight into your bank account as a separate revenue stream from your solar system, on top of what you save on energy bills.
Solar system owners need to register their system to have production tracked and certified before SRECs can be sold. To see what a larger commercial solar installation looks like in practice, browse our commercial solar project gallery.
4. Net Metering in Pennsylvania
Pennsylvania requires all investor-owned utility companies. PECO, PPL, Duquesne Light, Met-Ed, Penelec, Penn Power, and West Penn Power- to offer 1-to-1 net metering, according to the Pennsylvania Public Utility Commission.
What that means for your energy bills:
- Excess energy your solar panels generate gets sent back to the grid.
- Your utility provider credits you at the full retail electricity rate for that excess energy.
- Net metering credits roll over month to month and reset on an annual true-up date.
- Systems up to certain size thresholds qualify automatically; larger systems may need additional interconnection review.
Net metering is the piece that turns excess energy from a wasted resource into ongoing savings on your electricity bill.
5. PEDA Grants and Financing
The Pennsylvania Energy Development Authority (PEDA) offers financing and grants for clean energy projects, including solar. PEDA runs the Energy Accelerator Program, which serves as the state's green bank, using public and private capital to fund energy-efficiency and renewable-energy projects for businesses, schools, and nonprofits.
Loan programs tied to PEDA and related state financing tools often come with features built for businesses managing cash flow:
- Low fixed interest rates
- No prepayment penalties
- The ability to re-amortize the loan periodically without penalty

6. C-PACE Financing for Commercial Property Owners
Commercial Property Assessed Clean Energy (C-PACE) financing allows commercial property owners to finance energy improvements, including solar installations, with no money down.
Repayment happens through a special assessment on your property, similar to a property tax assessment, rather than a traditional loan.
C-PACE removes a major barrier for businesses that want solar but don't want to tie up working capital. It's voluntary, financed through private capital providers, and tied to the property rather than your personal or business credit alone.
7. USDA REAP Grants for Farms and Rural Businesses
The Rural Energy for America Program (REAP) is a federal USDA program, not a Pennsylvania-specific one, but it applies directly to farms and rural small businesses installing solar in the state. REAP grants can cover up to 50% of eligible project costs and stack with the 30% federal tax credit.
This program matters most for agricultural operations and rural businesses with large roof or land area for a solar panel system. We cover the specifics, including application windows, in our guide to financing options for farm solar.
It's also worth a look if your business is outside agriculture but operates in a rural area — we've seen similar economics play out in how solar pays off for auto dealerships, where large rooftop and lot space drives strong returns.
8. Local and Utility Rebate Programs
According to EIA.gov, over the last twenty years, Pennsylvania utility rates have gradually increased year-over-year between 1 and 5 %. However, with so many businesses going solar over the last year, utility companies have had to drastically increase rates to recoup costs.
Over the last year, average rates spiked by 21%. PPL utility rates increased by 38%. The data shows that businesses that do not switch to solar are essentially paying for that loss of business.
A few additional programs are worth checking, even though they're narrower in scope or currently limited:
- Pennsylvania Sunshine Program: This state program, run by the PA Department of Environmental Protection, originally offered up to $100 million in solar rebates for homeowners and small businesses. The program closed to new applications in 2013, but it set the template other PA solar incentives have followed since. Current grant and loan options for businesses run through the PA Solar Energy Program instead.
- Philadelphia Solar Rebate Program: Offers a per-watt rebate for systems inside city limits — historically $0.10 per watt for commercial projects. As of this writing, the city has paused new funding for this program, so confirm current availability before counting on it in your project budget.
- Homeowners Energy Efficiency Loan Program (HEELP): A Pennsylvania Housing Finance Agency loan program offering up to $10,000 for qualifying energy efficiency upgrades. It's built for homeowners, but it's worth knowing about if your business is a home-based operation or you're bundling a personal residence upgrade alongside a commercial project.
- Utility-specific rebates: Utilities like PECO periodically run their own incentive programs. As an example, PECO's current solar rebate program shows how a utility rebate stacks with federal incentives, even though that specific program targets residential customers.
9. Nonprofit and Government Direct Pay
Nonprofits, including faith-based organizations, schools, and municipalities, often have no tax liability, which used to lock them out of the federal tax credit entirely.
Under current IRS elective pay rules, tax-exempt entities can now receive a direct payment equal to the credit amount they would otherwise have earned — the same base 30% rate available to taxable businesses, plus the same bonus adders where they qualify.
Why Rising Utility Rates Make This Math Work in Your Favor
According to the U.S. Energy Information Administration, Pennsylvania utility rates climbed gradually for two decades, typically 1% to 5% a year.
That pace has picked up. Recent average rate increases have run well above historical norms in parts of the state, and PPL and PECO have each posted double-digit increases over short periods.
Every year your business doesn't generate its own electricity is another year of exposure to whatever your utility provider decides to charge next.
A solar system locks in a known cost today against an unknown electricity cost tomorrow. That's the core financial case for commercial solar, separate from any single incentive.

The Non-Financial Case: Carbon Footprint and Energy Independence
Clean energy generation helps your business meet environmental goals and appeals to eco-conscious customers and clients. Reducing your carbon footprint isn't just a marketing line — for many B2B buyers and procurement teams, supplier sustainability data is part of vendor selection.
Energy independence also has a practical side: a solar system reduces how exposed your operating costs are to grid disruptions and rate hikes. We go deeper on the broader shift toward renewable energy in why renewable energy is the future of the Mid-Atlantic grid and how solar power is reshaping the U.S. electricity grid.

Every one of these programs has its own eligibility rules, deadlines, and paperwork. TerraSol Energies prepares a free, custom solar savings report for Pennsylvania businesses, showing which incentives apply to your facility and what your system would look like financed versus paid in cash.
We've used this same incentive stack on projects ranging from off-grid commercial systems to large industrial installations as the leading commercial solar installer in the PECO region.
If your business hasn't run the numbers since the rules changed in 2025, now is the time. And that's exactly why understanding commercial solar incentives in Pennsylvania is worth a fresh look this year.
Frequently Asked Questions
What is the federal tax credit for commercial solar in Pennsylvania?
Businesses can claim a 30% federal tax credit under Section 48E on solar systems they own. Energy Community and Domestic Content adders can each add 10 percentage points on top of that base rate.
Is the federal solar tax credit still available in 2026?
For businesses, yes. The commercial ITC under Section 48E remains active. The residential credit (Section 25D) expired December 31, 2025, but that change does not apply to business-owned systems.
How do Pennsylvania SRECs work?
Your solar system earns one solar renewable energy credit for every 1,000 kWh it generates. You sell those credits to utility companies or on the open market, separate from your electricity bill savings.
Does Pennsylvania require net metering?
Yes. The Pennsylvania Public Utility Commission requires all investor-owned utilities to offer 1-to-1 net metering, crediting excess energy at the full retail rate.
Is there a Pennsylvania state rebate for commercial solar?
There’s no single statewide rebate check for commercial systems today. Instead, businesses combine the federal tax credit, bonus depreciation, SRECs, net metering, and financing programs like PEDA grants and C-PACE.
