Verdict: at average Nevada numbers, solar is a solid investment in 2026 — payback takes 10.5 years, leaving you $19,477 ahead after 25 years. The main reasons: cheap power (the 6th-lowest price of 51), which caps what each kWh saves; strong sun (the 3rd-best yield of 51); export credits below retail (exports earn ~75% of retail), so only the solar you use yourself earns full value. Pay cash if you can: Berkeley Lab found loan-financed systems priced about $1.50/W above cash installs in 2025, which can add years to the payback.
Net metering and exports in Nevada: NV Energy (<25 kW): excess energy credited at 75% of retail rate, credits roll forward.
Battery: a 13.5-kWh battery at the Nevada average of $932/kWh adds $12,582 and shifts about 4,165 kWh a year from low-paid exports to your own use; payback becomes 18.9 years.
EnergySage's Nevada page lists a 17.6-year payback. Its method is not fully published; ours uses EIA's Jan–Aug 2026 price, 40% self-use and the state's export credit, 3%/yr rate growth and 0.5%/yr panel aging, with no federal credit.
