Solar in New Castle FAQ
+How much does residential solar cost in New Castle?
A typical 8–10 kW system in New Castle, Delaware runs $20,000–$35,000 before incentives. The federal residential solar tax credit (25D) ended for systems installed after December 31, 2025, so savings now depend on Delaware state programs, utility rebates, and net-metering rules.
+How long does solar permitting take in New Castle?
On-site install runs 1–3 days. New Castle permitting and PTO can add 4–10 weeks depending on the utility.
+Do I need a battery with solar in New Castle?
Optional — a battery (Tesla Powerwall, Enphase) adds backup during Delaware outages and improves time-of-use savings under the local utility's rate plan.
