Wyoming solar leads

Sunlight on a Cheyenne array

Cheyenne is the largest city in Wyoming in the Census Bureau’s July 1, 2025 estimates. The PVWatts calculator, first built by NREL and now run by the National Laboratory of the Rockies, gives 5.38 kWh per square meter per day of solar radiation on an array there (checked October 9, 2026).

Method in one line: the calculator’s version 8 default array (fixed, open rack, facing due south, tilted 20 degrees) placed at Cheyenne’s Census gazetteer coordinates, with typical-year weather from the National Solar Radiation Database. Sites in the Bighorn Basin or the northeast plains, and roofs at other pitches, would read differently, so the number works as a reference point and not as a prediction for one house.

What the Wyoming net metering statute says

Wyoming writes its net metering terms into statute rather than a commission rule. Chapter 16, article 1 of Title 37 (W.S. 37-16-101 to 37-16-104, 2026 compilation, checked October 9, 2026) covers electric utilities, which the statute defines as electrical companies, irrigation districts and electric cooperatives that sell to retail customers; the definition of electrical company leaves out municipalities. A qualifying system runs on solar, wind, biomass or hydropower, has a generating capacity of no more than 25 kW, sits on the customer’s premises, operates in parallel with the utility grid and is meant mainly to cover the customer’s own use.

Under W.S. 37-16-103, the utility measures net use over each billing period. When the customer generates more than the utility supplies, the excess kilowatt-hours are credited or compensated on the next month’s bill. At the beginning of each calendar year, any unused credit from the previous year is sold to the utility at its filed avoided cost. W.S. 37-16-102 requires the utility to offer a meter that registers flow in both directions and bars any fee that would lift a net metering customer’s minimum monthly charge above that of others in the same rate class.

W.S. 37-16-104 adds the equipment side: systems meet the safety and performance standards of the National Electrical Code, the IEEE and UL, and the customer provides lockable switching equipment, approved by the utility, that can isolate the system from the grid. For a buyer, the 25 kW ceiling is the useful line: it separates net metered home systems from larger projects that fall outside the statute.

Houses and their owners in Wyoming

Detached houses make up most of Wyoming’s housing. The Census Bureau’s table B25024 (ACS 5-year 2020-2024) counts 187,985 single-family detached homes among 277,141 housing units, or 67.8%, which is a higher share than in 33 other states. Table B25032 shows 145,647 owner-occupied detached homes, 83.4% of the 174,619 homes their owners live in.

Housing age and home values are covered on Wyoming window replacement leads, and heating fuels and degree days on Wyoming HVAC leads; this page does not repeat them.

Putting the Wyoming solar facts together

Read side by side, the figures above describe a small installed base, a housing stock made up mostly of owner-occupied houses and a net metering law with a fixed size limit. For a buyer planning Wyoming coverage, three points stand out:

• Most owner homes are houses. In the 2020-2024 ACS, 83.4% of owner-occupied homes are single-family detached, so homeowner status and house type rarely point in different directions here.
• The statute sets the project size. W.S. 37-16-101 (2026 compilation) caps net metered systems at 25 kW, a simple way to tell a home system from a larger project.
• Distance shapes coverage. The ten counties in the table above span the state, and the two largest metro areas held 183,464 residents combined in the Census Bureau’s July 1, 2025 estimates, so an installer’s ZIP code list follows the towns its crews can drive to.

These points describe the housing, the installed solar and the statute. They do not say how many solar leads exist in Wyoming or where any of them would come from.
