Questions about solar in Nevada
How does Nevada pay for solar power I send to the grid?
Nevada credits exports at about 75% of the retail rate for new customers. We assume you use 40% of your solar power at home, which makes the average solar kWh worth 10.9¢. This summary comes from secondary sources, so confirm it with your utility. Source.
How much did the end of the federal tax credit change payback in Nevada?
With the 30% credit that ended in 2025, the same system would have paid back in about 13.2 years instead of 18.9. The credit ended for systems installed after December 31, 2025. Leased systems and power purchase agreements can still pass on a business credit, but then you do not own the panels.
Is 1,753 kWh per kW a lot?
The range across states runs from about 922 kWh in Alaska to about 1,779 in the Southwest. Sunshine matters less than people expect: the electricity rate and how your utility credits exports move payback more.
