Solar vs. Grid Electricity in Nevada
Compare the 25-year cost of solar energy to staying on grid electricity, accounting for utility rate escalation, panel degradation, and IRA credits.
In Nevada, the average homeowner pays $13.2¢/kWh for grid electricity. With historical escalation of 3-8% per year, this rate is projected to reach $35.2¢/kWh in 25 years (at 4% escalation). A 7 kW solar system locks in an effective rate of $0.113/kWh for the life of the system.
The math is straightforward: grid electricity costs more every year while solar LCOE stays fixed. By year 10, the utility rate reaches approximately $19.5¢/kWh, nearly 1.7x the solar LCOE. This growing gap is the engine that drives solar ROI.
25-Year Cost Comparison
| Metric | Solar | Grid Only |
|---|---|---|
| Effective rate (year 1) | $0.113/kWh | $13.2¢/kWh |
| Effective rate (year 25) | $0.113/kWh | $35.2¢/kWh |
| 25-year discounted cost | $29,338 | $27,305 |
| Net savings (NPV) | $12,806 | |
Solar in Nevada produces 1,700 kWh per installed kW per year. A 7 kW system generates 11,900 kWh annually, offsetting 113% of the average household's 10,500 kWh annual consumption. After the 8-year payback period, every additional year of operation is pure savings.
