| Net cost after incentives | $14,000 |
| Annual savings (year 1) | $1,920.00 |
| Simple payback period | 7.3 years |
| Total savings over 25 years | $70,002 |
| Net savings over 25 years (after net cost) | $56,002 |
A $20,000 system with $6,000 of incentives nets $14,000; offsetting 80% of a $2,400 bill saves $1,920 a year, paying back in about 7.3 years and saving about $70,002 over 25 years at 3% price inflation.
Net cost = Cost − incentives; Annual savings = Bill × offset%; Payback = Net cost ÷ annual savings · Powered by CalcHub — Solar Payback Calculator
