How does the 30% Federal Solar & Battery Tax Credit (IRS Section 25D) work in 2026?

Under the Inflation Reduction Act, US homeowners can claim a dollar-for-dollar 30% federal income tax credit (IRS Form 5695) on the total installed cost of solar PV panels and standalone battery storage systems with a capacity of 3 kWh or greater.

Can I stack the 30% Federal ITC with State HEEHRA/HOMES rebates and VPP payouts?

Yes. Homeowners can combine the 30% Federal Tax Credit with state-administered DOE HEEHRA point-of-sale rebates (up to $8,000 for heat pumps and $4,000 for 200A panel upgrades) plus annual Virtual Power Plant (VPP) grid dispatch rewards ($850–$1,800/year).

Why is a LiFePO4 battery essential under California NEM 3.0 and Texas ERCOT?

Under California NEM 3.0 (Net Billing Tariff), daytime solar export rates dropped by ~75%, while evening peak export credits reach $2.00–$3.00/kWh in August and September. A 16–32 kWh LiFePO4 battery stores midday solar and discharges during peak hours or ERCOT/CAISO VPP events.
