⚠️ Results are estimates for planning purposes only. Actual savings depend on local
utility rules, roof conditions, installer pricing, exact electricity consumption, and local/state
incentives. The federal homeowner solar tax credit (ITC/Section 25D) expired December 31 2025 under
the One Big Beautiful Bill Act. Consult a licensed solar installer and tax professional before
purchasing.
