Solar ROI Overview for Kansas
In Kansas, solar payback is driven primarily by your electricity rate ($0.151/kWh) and net-metering policy, not by sun hours alone. A typical 8kW residential system here costs about $20,080, saves $1,748 per year, and pays for itself in11.5 years. While Kansas averages 4.6peak sun hours per day, the rate you pay your utility (and how your solar exports are credited) matters more for ROI than raw sunshine. See why below.
- Electricity rate: $0.151/kWh average in Kansas
- System cost: about $20,080 before incentives ($2.51/W)
- Production: about 11,552 kWh/year
- Annual savings: $1,748 ($146/month)
- Payback: 11.5 years
- 25-year ROI: 118%
Savings use an NEM-adjusted effective rate (~$0.151/kWh for Kansas), reflecting net metering export compensation rather than full retail.
Why your electricity rate matters more than your sun hours
Across all 50 states, electricity rate and net-metering policy explain most of the variance in solar payback, far more than peak sun hours. Hawaii and Washington make the case: Hawaii has only middling sun hours but the highest residential rates in the country, so it pays back fastest. Washington has decent Pacific Northwest sun but cheap hydro keeps rates low, so it pays back far more slowly. The rate you pay your utility, and how your exports are credited, is the dominant lever.
| State | Rate ($/kWh) | Sun hours | Payback |
|---|---|---|---|
| Hawaii | $0.520 | 6 | 3.2 yrs |
| Washington | $0.149 | 3.7 | 16.6 yrs |
| Kansas (you) | $0.151 | 4.6 | 11.5 yrs |
Kansas's 11.5-year payback is slower than the national average of about 10.9 years, driven by your $0.151/kWh rate and local net-metering rules, not by 4.6 peak sun hours. (Hawaii's faster payback and Washington's slower payback are the same story at the extremes.)

How Solar Payback Works in Kansas
Solar payback period is the time it takes for your cumulative electricity savings to equal the total cost of your solar system. In Kansas, the calculation depends on three key factors:
- System cost — $2.51/Watt average in Kansas
- Electricity rate — $0.151/kWh average utility rate
- Solar production — 4.6 average peak sun hours/day
After the payback period of 11.5 years, your solar panels continue generating free electricity for 15-20+ more years. With utility rates historically increasing 2-4% annually, your actual savings will likely exceed these estimates.
