Pacific Sky Power wind turbines work efficiently to harness free renewable energy from the wind. Larger wind turbines kill birds and are not permitted in many areas. The modular frame uses a 3/4″ pvc or steel conduit structure for mounting that is adaptable to many different roof designs. The system works like solar to increase the capacity factor using many wind turbines together. Modules are easily added or removed for experimenting and configuring the ideal wind power system for your home.
