As of 2025, this credit continues to serve as a powerful financial incentive, making both residential and commercial battery energy storage systems more accessible. The new budget package revises critical incentives laid out by the IRA, focusing particularly on foreign sourcing restrictions, new domestic. . Additionally, the OBBB provides for energy projects to be depreciated in a 1-year timeline vs. the 5-years MACRS schedule (plus bonus) under the IRA and earlier legislation. Under this new law, homeowners who purchase their systems with cash or a loan will no longer be eligible for the 30% federal tax credit after December 31, 2025. . BESS helps solve grid intermittency and increase the economics of renewable energy by capturing excess energy for later use when there is demand, available transmission, or favorable pricing. . In this guide, we break down how each element can make your solar setup more efficient, resilient, and financially rewarding.

When does the solar tax credit expire?
The federal solar tax credit for customer-owned systems expires December 31, 2025—but solar's long-term value extends far beyond this incentive. Why trust EnergySage? The federal solar investment tax credit (ITC)—Section 25D of the U.S. Tax Code—expires for customer-owned residential solar systems installed after December 31, 2025.
Can I claim a solar system tax credit?
you to claim 30% of the cost of your solar system as a credit to your federal tax bill. For example, if it cost $10,000 to install your solar system, you'd receive a $3,000 credit, which would directly reduce your tax bill.
What does a solar installation tax credit cover?
The credit typically covers solar panels, inverters (including Enphase microinverters), battery storage, wiring, mounting hardware, and installation labor. It may also apply to permitting fees, inspection costs, and sales tax in some states. Always check with a tax advisor to confirm which costs are eligible for your specific installation.
What is the new solar tax credit?
This legislation brings significant changes to the federal tax credit for residential and commercial solar and battery systems. Under this new law, homeowners who purchase their systems with cash or a loan will no longer be eligible for the 30% federal tax credit after December 31, 2025. Previously, this solar tax credit was available through 2034.
Flexible, wide-duration energy storage systems represent a new category — engineered to deliver value across a range of use cases and timeframes. . Short-duration systems — most commonly lithium-ion-based — are commercially mature and highly efficient for applications like daily peak shaving, frequency regulation, and short-term arbitrage. However, their effectiveness is constrained by depth-of-discharge limitations and balance-of-plant. . What are flexible energy storage systems? Flexible energy storage systems represent an essential advancement in the energy sector, characterized by several defining features.
