The 30% Investment Tax Credit (ITC)
Through 2032, the federal ITC gives you a tax credit (not deduction) equal to 30% of your solar and battery storage system cost. On a $25,000 solar + $10,000 battery system, that's $10,500 back on your federal taxes.
Annual Home Energy Credits
Separate from the ITC: up to $1,200/year for energy-efficient home improvements (windows, doors, insulation, HVAC) under the Energy Efficient Home Improvement Credit.
💡 Tax credits reduce your tax bill dollar-for-dollar. If your total tax liability is less than the credit, the solar ITC can roll forward to future years.
⚡ CalcWolf Insight
Combined federal + state solar incentives average $12,000–18,000 per installation in 2026. Over 20 states offer additional credits on top of the federal ITC.
