Incentive status
Pennsylvania Solar Incentives
Incentives can materially change net cost, but SolarCalcNow does not include them in default calculations unless they are source-checked, dated, active, eligibility-scoped, and explicitly included in the data model.
Residential Clean Energy Credit, Section 25D
The calculator does not include a federal homeowner solar tax credit by default for new estimates because reviewed IRS source status treats Section 25D as unavailable after the 2025 cutoff.
IRS OBBB FAQ states the Section 25D credit is not allowed for expenditures made after December 31, 2025. SolarCalcNow excludes it from new 2026 homeowner estimates unless a qualified tax review confirms a specific timing scenario.
Amount: Not applied to new 2026 homeowner estimates.
Calculator treatment: Excluded because current source status is expired.
- Confirm expenditure timing with official IRS guidance.
- Do not treat older IRA-era 30% homeowner credit copy as current for new 2026 estimates.
- Tell users to consult a qualified tax professional for tax eligibility questions.
State and local solar incentives
State, utility, and local incentives can materially change payback, but they need active-status verification before publication.
Check SREC market assumptions, utility programs, and local incentives before modeling net cost.
Amount: Requires official state/utility review before any dollar amount is shown.
Calculator treatment: Excluded until source, status, amount, and eligibility are verified.
- Open DSIRE and official state/utility pages for the user's state and utility territory.
- Record official source URL, updated date, active/paused/expired status, and eligibility scope.
- Only allow net-cost inclusion when amount, eligibility, and active status are source-checked.
How incentives affect the estimate
The calculator shows gross cost first. A verified incentive can be shown as a separate note or included in net cost only after its source, active status, eligibility rules, and date are reviewed. This keeps outdated tax credit assumptions from quietly changing payback math.
