Verdict: at average Nebraska numbers, solar is a marginal investment in 2026 — payback takes 12.1 years, leaving you $31,156 ahead after 25 years. The main reasons: cheap power (the 2nd-lowest price of 51), which caps what each kWh saves. Get at least three quotes: every $0.25/W you shave off the price moves payback by roughly a year or more here.
Net metering and exports in Nebraska: Not verified for this page — check your utility's net metering or export-credit tariff before you sign. The calculator assumes 1:1 kWh net metering (the best case).
Battery: a 13.5-kWh battery at the Nebraska average of $910/kWh adds $12,285 and saves almost nothing extra under 1:1 net metering — buy it for backup, not payback; payback becomes 17.7 years.
Lease or PPA instead? The owner can still claim the 30% 48E credit if construction began by July 4, 2026 or the system is in service by Dec 31, 2027 — ask whether that discount is in the monthly price.
