Solar Panel ROI by Region (10kW System)
| Region | System Cost | After 30% Credit | Annual Savings | Payback |
|---|---|---|---|---|
| California | $28,000 | $19,600 | $2,200 | 8.9 years |
| Texas | $25,000 | $17,500 | $1,800 | 9.7 years |
| Florida | $26,000 | $18,200 | $1,900 | 9.6 years |
| Arizona | $24,000 | $16,800 | $2,100 | 8.0 years |
| Pacific Northwest | $26,000 | $18,200 | $1,200 | 15.2 years |
Pacific Northwest has cheap hydro power — solar has less value there.
Heat Pump vs Gas Furnace + AC
- Gas furnace + central AC: $2,400/year HVAC energy
- Heat pump: $1,100/year
- Annual savings: $1,300
$12,000 heat pump install minus $2,000 federal credit = $10,000 net. Payback: 7.7 years.
Insulation: Highest ROI of All
- Attic insulation: $1,500-$3,500 install, saves $350-$700/year
- Air sealing: $500-$2,000, cuts heating/cooling 10-20%
- After 30% tax credit: payback in 3-5 years
The least glamorous upgrade often has the best return.
