How Las Vegas homes get paid for solar
Export rules are set at the state and utility level, not by the city. Las Vegas is under Nevada's net billing: NV Energy credits exported solar at 75% of the retail rate for 20 years (Tier 4, state law AB 405, since 2020); no capacity cap. The full rules, incentives and sources are on theNevada page.
Why the city matters
Two things change from one city to another in the same state: the sun, which sets how many panels you need, and the utility, which sets what exported power is worth. Las Vegas gets 1,770 kWh per kW a year on a south-facing roof at a 20° tilt, so covering a year of use for a $150 bill at 13.5¢ takes about 7.5 kW, roughly 19 panels of 400 W. Electricity prices in the calculator are the Nevada residential average; your utility's rate can be higher or lower, so put your own bill in.
