Quick answer
Pennsylvania solar economics depend on your roof, utility and quote. This page uses illustrative assumptions of 4.2 peak sun hours, $3/W and 15.0 cents/kWh; these are not verified current market averages or account rates.

- Best for
- Pennsylvania homeowners comparing solar costs, incentives, and payback assumptions.
- Inputs needed
- annual kWh usage, utility rate, installed $/W, net-metering policy
- Formula used
- Planning production = system kW x peak sun hours x 365 x (1 - 14.08% losses). Retail-value ceiling = production x assumed retail price; actual export value can be lower.

Pennsylvania net metering: monthly credits are not the same as annual cash-out
Under 52 Pa. Code section 75.13, default-service customer-generators receive applicable retail credits during the billing cycle. Remaining generation not already credited at the end of the annual period is compensated at the default-service provider's price to compare. That is not a promise of the full delivered retail rate for every surplus kWh.
If you buy supply from a competitive electric generation supplier, excess-energy compensation belongs in that supplier agreement. Check supply and delivery treatment separately. Eligible generators retain alternative energy credits unless a contract assigns or rejects that ownership.
PA SREC prices are market quotes, not a fixed state rebate. Ask whether the quote is a spot price, a multi-year contract or a broker estimate, and subtract fees. One certificate represents 1,000 kWh of eligible production; do not count the same credit income twice.
Worked example, not an account quote
Illustrative SREC sensitivity, not a current price: 10,000 eligible kWh is 10 certificates. At hypothetical prices of $15, $30 and $45 per certificate, gross proceeds would be $150, $300 and $450 before fees. At annual settlement, 1,000 excess kWh at a hypothetical $0.10/kWh price to compare is $100, not $250 at a $0.25 delivered rate.
Documents to request before deciding
- Name the distribution utility and supply provider on the bill.
- Find the annual settlement date and current price-to-compare schedule.
- Confirm system certification, certificate ownership, broker fees and contract term.

One eligible SREC represents 1,000 kWh. Certificate prices are not fixed state rebates, and annual excess-energy cash-out is not necessarily the full delivered retail rate.

Includes 14.08% planning losses. Valuing all production at retail is a ceiling, not a net-billing savings estimate; actual self-use, export rates and ownership costs change the result. No new Section 25D homeowner credit in 2026.

Pennsylvania Net Metering Policy
Full retail net metering
52 Pa. Code section 75.13 distinguishes retail bill credits from remaining annual excess, which default-service providers settle at the price to compare. Competitive-supplier compensation follows the supplier agreement. SREC income depends on eligibility, ownership and market or contract prices.
Pennsylvania Solar Incentives
Programs require eligibility checks and cannot always be combined. Federal 25D credit is $0 for new homeowner-owned systems in 2026.
- ✓SREC market: obtain a current quote, confirm certificate ownership and subtract fees
- ✓Property tax treatment: check the municipality
- ✓Sustainable Energy Fund financing: check current project eligibility

State-specific decision guide
What to verify before signing a Pennsylvania solar quote
In Pennsylvania, the financial result depends on more than sunshine or the headline installation price. Confirm the export rule, program eligibility date, and interconnection timeline for your exact utility before treating a payback estimate as a promise.
Export value
This page models full retail net metering. Ask which tariff and export credit apply to your account, not only which program name appears in the proposal.
Incentive eligibility
Check equipment, income, installer, application, and placed-in-service rules before subtracting an incentive from the quote. Programs can close or change terms.
Interconnection
Budget for the published 5–10 weeks and confirm who pays for a required meter, service upgrade, or engineering review.
Source trail: production assumptions use NREL PVWatts; incentive discovery should be checked against DSIRE; electricity-market context is available from the EIA. Confirm final tax treatment with the IRS and your utility.
