Solar in Nevada: the 2026 numbers
A household here spending $200 a month on electricity needs roughly a 10.1 kW array, which generates about 17,685 kWh in its first year. Bought outright, it returns its cost in year 15 and is worth $1,820 over 25 years — after discounting, after upkeep, and with no federal credit.
Our answer for Nevada: cash purchase
Of the four options, a cash purchase has the highest net present value at $1,820 , turning cash-positive in year 15 . Solar stops making sense in Nevada above roughly $3.18/W installed — if a quote comes in above that, the answer flips.
What Nevada gives you to work with
| Sunlight (specific yield) | 1751 kWh per installed kW per year — NREL PVWatts v8, Las Vegas |
| Average residential rate | $0.136/kWh — EIA, May 2026 |
| Export credit | 75% of retail — Excess energy credited at 75% of retail after monthly netting, locked for 20 years from installation. |
| Federal credit on a purchase | None — §25D expired after December 31, 2025 |
| State incentives | Checked, and there is no cash incentive — reviewed 2026-08-15 |
The four options, run side by side
A household spending $200 a month on electricity, with the array sized to cover its usage, at the default $3.00/W installed cost. This is the same case the calculator below opens on. Net present value discounts future dollars at 5%, so these are not the inflated “lifetime savings” totals a sales quote shows.
| Option | Net present value | Payback | Cost per kWh |
|---|---|---|---|
| Cash purchase You pay for it. No fee, no interest, no escalator. | $1,820 | Year 15 | $0.145 |
| Solar loan Includes the 20% dealer fee that a low-APR solar loan hides in the financed price. | -$10,004 | Never | $0.195 |
| Lease You rent the system. The owner keeps the §48E credit. | -$5,968 | Never | $0.178 |
| PPA You buy the output per kWh, not the hardware. | -$11,041 | Never | $0.200 |
A cash purchase delivers electricity at $0.145/kWh while the utility charges $0.136. Generating your own is more expensive than buying it here, which is the core problem.
Best option: Cash purchase — $1,820 net present value over 25 years, paying back in year 15.
| Option | Owns it | 30% credit | Upfront | 25-yr NPV | Payback | Cost/kWh |
|---|---|---|---|---|---|---|
| Cash purchase | You | None | $30,300 | $1,820 | Year 15 | $0.145 |
| Solar loan | You | None | $0 | -$10,004 | Never | $0.195 |
| Lease | Provider | Indirect (§48E) | $0 | -$5,968 | Never | $0.178 |
| PPA | Provider | Indirect (§48E) | $0 | -$11,041 | Never | $0.200 |
What this calculation assumes, and where it can be wrong
Federal credit. The 30% federal residential credit (IRC §25D) expired for systems placed in service after December 31, 2025. A 2026 cash or loan purchase receives no federal credit. Leases and PPAs remain eligible indirectly: the third-party owner claims the commercial credit (IRC §48E) and reflects part of it in the price offered, provided the system is placed in service by December 31, 2027.
Estimated §48E value in a lease or PPA quote: about $4,545 for this system, assuming the provider passes through half the credit. That share is our estimate, not a published figure.
Export credit. Excess energy credited at 75% of retail after monthly netting, locked for 20 years from installation.
State incentives. Nevada has no state income tax, so a state tax credit cannot exist, and there is no statewide cash rebate for residential PV. The state's one real concession is the export rate: NV Energy credits excess generation at 75% of retail after monthly netting, and that rate is locked for 20 years from installation — a guarantee few states offer. Nevada's problem is not the policy, it is that the electricity being displaced is cheap.
- Cash purchase: No federal tax credit is applied: IRC §25D expired for systems placed in service after 2025-12-31.
- Solar loan: Financed amount includes a 20% dealer fee, which is why a $0-down loan quote costs more than the same system bought outright.
- Solar loan: No federal tax credit is applied: IRC §25D expired for systems placed in service after 2025-12-31.
- Lease: Pricing assumes the system owner claims the §48E credit and reflects part of it in your quote. The system must be placed in service by 2027-12-31 to qualify.
- PPA: Pricing assumes the system owner claims the §48E credit and reflects part of it in your quote. The system must be placed in service by 2027-12-31 to qualify.
Sunlight data: 1751 kWh per installed kW per year (verified — NREL PVWatts v8). Retail rate: $0.136/kWh.
Why Nevada lands where it does
Across the 50 states we model, Nevada ranks #32 on the value of a cash purchase, at $1,820 — behind Nebraska at $1,823 and ahead ofIowa at $1,801 . The ordering is not the one people expect, and the reason is worth stating plainly: sunshine matters less than the price of the electricity you stop buying.
Nevada gets 1751 kWh per installed kW per year and pays $0.136 per kWh. That is a lot of sun and cheap power — the combination that flatters brochures and disappoints spreadsheets. Every kWh the array makes displaces only $0.136 of bill, so the hardware has to be very cheap before the arithmetic works.
The export rule is the main event here
Nevada credits exported electricity at 75% of retail. Excess energy credited at 75% of retail after monthly netting, locked for 20 years from installation. On the reference system, about 11,495 kWh a year leaves the house rather than being used in it, and the gap between what that power is worth on your bill and what the utility pays for it costs $391 a year.
That single number is the difference between the answer on this page and the answer on a calculator that values every kWh at retail — which is what almost all of them do. It is also why self-consumption is the lever that matters most in Nevada: shifting load into daylight hours, or adding a battery, an EV or a heat pump, converts exported kWh worth $0.102 into avoided kWh worth $0.136.
What the state actually pays you
Nevada has no state income tax, so a state tax credit cannot exist, and there is no statewide cash rebate for residential PV. The state's one real concession is the export rate: NV Energy credits excess generation at 75% of retail after monthly netting, and that rate is locked for 20 years from installation — a guarantee few states offer. Nevada's problem is not the policy, it is that the electricity being displaced is cheap.
So there is no cash incentive to model. That matters more than it used to: while the 30% federal credit existed, a state with no programme of its own was still fine. Now, Nevada buyers are on their own entirely, and the whole case has to come from the bill savings.
The financing trap
A solar loan is worth -$10,004 here against $1,820 for the same system bought outright — a gap of $11,824. The interest rate is not what causes that. A 20% dealer fee is embedded in the financed price, which is how a "1.99% APR" offer ends up costing more than a bank loan at 8%. It is rarely on the quote. Ask for it by name.
Lease and PPA look different from a purchase for a structural reason: the third-party owner still claims the 30% §48E credit, which a homeowner buying outright can no longer get. How much of that credit reaches you in the price is a negotiation, and we assume half. The owner also carries the upkeep and the inverter replacement that a buyer pays for. That is why they still trail a cash purchase here, though by much less than they would have in 2025. Both are tied to systems placed in service by December 31, 2027 — see the 2027 deadline.
Before you accept a Nevada quote
- Confirm it does not apply the expired 30% federal credit.
- Ask what export rate it assumed. Nevada credits exports at 75% of retail; if the quote valued every kWh at $0.136, its savings figure is overstated.
- Check the price per watt. Above about $3.18/W the purchase stops paying for itself in Nevada.
- Ask for the dealer fee on any financed offer, as a dollar amount.
- If it is a lease or PPA, ask for a placed-in-service commitment — §48E requires the system running by December 31, 2027.
