Who can install this system?

Southwest Windpower recommends installing Skystream 3.7 at sites with the following criteria:

Adequate wind resource: Minimum average wind speed for Skystream 3.7 is 10 mph (4.5 m/s). Ideal sites have 12 mph (5.4 m/s) average wind or greater.
Site free from obstructions: Clean, unobstructed wind is best for Skystream 3.7. The top of the tower should be a minimum of 20 feet (6.5 m) above any surrounding object within a 250 foot (76 m) radius. Although the machine can be installed on smaller lots of land, properties of one acre or more are typically ideal as they will more likely have unobstructed wind.
Suitable zoning: Tower installation must comply with local zoning regulations. It is also advisable to make sure there are no HOA (Home Owner Association) regulations that prohibit the use of towers.
Interconnection with utility: Local utility must allow for interconnection. The 1979 federal PURPA act requires small systems can connect to the electrical grid; but interested consumers should consult their local utility.
Electricity cost of $0.10/kWh or greater: Interested parties should consult with their local utility or look at their electric bill.
