About Solar Panel Installation in Wilmington
Solar panel installation involves mounting photovoltaic panels on rooftops or ground-mount systems, wiring them to inverters, and connecting to your electrical panel or battery storage. A properly sized system can significantly reduce or eliminate electricity bills.
Typical costs: Residential solar systems typically cost $15,000–$30,000 before incentives. After federal tax credits (currently 30%) and local rebates, net cost is often $10,000–$20,000 for a standard 6–10 kW system.
Common projects include:
- Rooftop residential solar installation
- Ground-mount solar arrays
- Battery storage integration
- Solar panel system upgrades and expansion
- EV charger + solar combo installations
Solar installations almost always require electrical and building permits. Your installer should handle the permit application, utility interconnection agreement, and final inspection.
