Pennsylvania solar is booming — but we’re at risk of leaving billions of federal tax credits on the table if projects don’t move fast.
New from Keystone Research Center: “Use It or Lose It: Why Pennsylvania Should Accelerate Solar Projects to Capture Federal Tax Credits.” The report documents a six-fold increase in PA solar capacity since 2019 (now 2.24 GW installed by the end of 2025) and lays out a roadmap to keep that momentum going — especially as timelines for key Inflation Reduction Act (IRA) tax credits are being shortened under the “One Big Beautiful Bill Act.”
A few findings:
- PA solar projects have already claimed $500M+ in IRA investment tax credits through 2025
- Electricity prices are climbing (industrial rates up ~50% since early 2020; residential up ~25%)
- Building even half the projects already in the PJM/utility queues could mean 6.5 GW more solar and $8B+ in total investment
- Real-world case studies show payback periods of 8 years or less with the 30% tax credit — including schools, municipalities, and businesses across the Commonwealth
