Wind Turbines by Southwest Windpower

Harnessing the power of the wind is made possible by the wind power experts at Southwest Windpower, the world leader in small wind turbine manufacturing, sales, and exports, and maker of the Air-X and Whisper line of wind turbines.  Southwest Windpower designs products to efficiently capture abundant wind energy resources and at these low prices, wind power offers a cost effective way to meet your energy needs.  ETA Engineering also carries accessories for Southwest Windpower wind turbines, including professional engineer certified tower kits, a variety of wind power and solar charge controllers and an assortment of water pumps.

Wind power and solar power are complementary in the sense that when a wind resource is not available, sunshine often is.  If both resources are available, then a hybrid system is the more economical approach.  A hybrid system uses fewer batteries and the battery bank is cycled less, which results in longer battery lifetimes and lower costs.  If you already have a wind turbine, consider adding solar panels to your system for extra dependability and long term cost savings.  If you already have solar panels, then you've come to the right place for dependable wind turbines and accessories.
