25-year savings projection for Nevada
This projection starts from Nevada's assumed $0.15/kWh electricity rate and 1,670 kWh/kW of annual production, then grows savings by 3% a year as electricity prices rise and reduces output by 0.5% a year as panels degrade.
| Year | Annual savings | Cumulative savings | vs. $22,200 cost |
|---|---|---|---|
| Year 1 | $1,651 | $1,651 | −$20,549 |
| Year 5 | $1,822 | $8,677 | −$13,523 |
| Year 10 | $2,060 | $18,487 | −$3,713 |
| Year 15 | $2,328 | $29,579 | +$7,379 |
| Year 20 | $2,633 | $42,118 | +$19,918 |
| Year 25 | $2,976 | $56,295 | +$34,095 |
A simple, undiscounted projection — it does not apply a discount rate, financing interest, inverter replacement (commonly needed once in 25 years), maintenance, or any change in home value. Treat it as a shape, not a forecast. See methodology.
Why savings look like this in Nevada
Excellent sun and a legislatively fixed export rate at a high share of retail make Nevada one of the stronger Western markets.
The single biggest variable is what your utility pays for exported power. Nevada credits exports at 75% of the retail rate under its restored net metering law (rate tier fixed at time of interconnection), applied by NV Energy.
What would change this number
- Your actual rate. This uses a $0.15/kWh Nevada average. If you pay more, savings scale up roughly proportionally.
- Self-consumption. We assume 68% of output is used on site at retail value and the rest exported at 45% of retail. Households home during the day, or with a battery, do better.
- Electricity price growth. At 3% a year, savings nearly double by year 25. Slower growth meaningfully reduces lifetime return.
- Incentives. Nevada's main program — nv energy storage incentives — reduces net cost and shortens break-even. See Nevada incentives →
- Financing. A cash purchase earns the return above. A loan shifts it — interest can consume a large share of lifetime savings.
Frequently asked questions
How much can you save with solar panels in Nevada?
An 8 kW system in Nevada could save roughly $1,651 in the first year — about $138 a month — and around $56,295 across 25 years, assuming electricity prices rise 3% a year and panel output declines 0.5% a year. Against a midpoint installed cost of $22,200, that is a net gain of about $34,095.
What is the ROI on solar panels in Nevada?
On these assumptions, roughly 154% over a 25-year system life — $34,095 of net savings on a $22,200 system. That is a simple, undiscounted return: it ignores financing interest, the time value of money, and any effect on home resale value. A cash purchase and a loan produce very different numbers.
How long does it take for solar to pay for itself in Nevada?
Around year 12, when cumulative savings first exceed the $22,200 installed cost. A simple payback that ignores rising electricity prices gives a wider range of 12–15 years.
Do solar savings in Nevada include the federal tax credit?
No. The 30% federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025, so none of these figures include it. Any savings projection you see elsewhere that still applies 30% to a 2026 purchase is overstating the return.
What most affects solar savings in Nevada?
Three things, in order: your utility's export compensation (Nevada credits exports at 75% of the retail rate under its restored net metering law (rate tier fixed at time of interconnection), applied by NV Energy.), how much of the output your household consumes on site rather than exporting, and your actual electricity rate versus the 0.15/kWh state assumption used here. NV Energy storage incentives can improve the result further.
