How to Save Money
The federal solar tax credit covers 30% of installation costs through 2032. A $20,000 system effectively costs $14,000 after the credit. Average payback period is 6-9 years depending on electricity rates and sun exposure. In high-electricity states (CA, CT, HI, MA), solar pays back in 5-7 years. In cheap-electricity states (LA, WA), 10-12 years.
