Wind Power has a versatility of uses. The wind turbines below are used worldwide for battery charging, home power, and water pumping applications, and range from 400 to 65,000 watts. Wind Turbines start producing power at 7.5 mph wind speed, and increase their output through 45 mph winds. Higher wind speeds require the blades to be slowed down, to protect the equipment, but are very effective in wind speeds between 7.5 and 45 mph. Whether you're using wind power for your home or business, or you're planning a wind farm, TECHNICAL INFORMATION PAGES below.
