Federal Solar Tax Credit Eliminated Jan 1, 2026
Battery storage no longer qualifies for the 30% federal ITC (Section 25D expired December 31, 2025). All payback calculations below reflect post-25D reality — no federal credit is applied. Your economics are driven by TOU arbitrage, backup value, state incentives, and Virtual Power Plant revenue.
Battery-Only Payback Calculator
At what price does a home battery actually pay for itself? Get an honest answer with state-specific rates, backup value, incentives, and Virtual Power Plant revenue — for homeowners with or without solar.
Most battery calculators were built before the 25D elimination. Ours reflects 2026 reality — modeling VPP revenue, TOU arbitrage, backup value, and state-specific incentives that generic tools miss.
Your Situation
Heads up: A battery without solar has limited upside. It can still earn through time-of-use arbitrage, outage protection, and Virtual Power Plant programs — but it can't capture free solar charging. The math below reflects that honestly.

Section 25D — which required a battery to be charged by renewables ≥80% of the time — expired December 31, 2025. Owned-residential batteries installed in 2026 receive no federal tax credit. A Section 48E credit is available only for leased/PPA batteries that began construction before July 4, 2026.

Assumptions & data sources: Calculations assume ~1 full cycle/day, 90% depth-of-discharge and 90% round-trip efficiency, ~$5/kWh value of lost load for outage protection, and a 3%/year electricity-rate escalator. The federal Residential Clean Energy Credit (25D) expired December 31, 2025, so no federal credit is applied to net cost for owned-residential batteries in 2026. State time-of-use peak/off-peak spreads, battery incentives, outage hours, and Virtual Power Plant programs are curated averages — as of 2026 and subject to change. Always verify current programs with your utility and the DSIRE database.
