Wyoming presents significant solar challenges: Despite 5.0 daily peak sun hours, the Equality State ranks near the bottom for solar with 11¢/kWh electricity rates and minimal state support. Rocky Mountain Power serves much of the state with limited net metering.
For Cheyenne and Casper residents, solar systems typically take 12-14 years to pay back. Low electricity costs from abundant coal and natural gas make solar less economically attractive.
