Is solar worth it in Wyoming?
A typical 7 kW rooftop system in Wyoming produces roughly 9,800 kWh a year, about 95% of what an average home here uses. At the state’s average price of 14.0¢, that power is worth about $1,367 a year. What you actually save depends on your roof, the price you pay for the system, the 30% federal tax credit rules in effect when you buy, and how your utility credits the power you send to the grid.
