Key cost drivers
Several factors determine where a project falls within that range:
- System size – measured in kilowatts (kW); larger systems need more panels and hardware.
- Roof type and condition – complex roofs or the need for structural reinforcement add labor.
- Equipment quality – premium inverters and high‑efficiency modules cost more but may boost output.
- Location – labor rates, permitting fees, and local utility interconnection rules vary by state and city.
Incentives and net cost
The federal Investment Tax Credit (ITC) currently covers 30% of qualified expenses, and many states offer additional rebates or tax credits. After applying these incentives, the out‑of‑pocket cost often drops to $10,000‑$21,000 for a typical 5‑6 kW system.
Financing options
Homeowners can choose cash purchase, solar loans, or power‑purchase agreements (PPAs). Loans spread the net cost over 5‑15 years, while PPAs require no upfront payment but lock in a fixed electricity rate.
