Abstract: The present invention provides a process and apparatus for an integrated wind-solar energy system utilizing an existing wind turbine infrastructure. This invention utilizes unused vertical space of an existing wind turbine steel support tower, and does not use the restricted ground around the wind turbine farm. Additionally, this invention uses the same electrical infrastructure as used for the wind turbine system. This invention provides a significant cost savings over other approaches. The present invention relates to a wind turbine support tower mounted solar system to increase the net electrical output using the existing wind turbine electrical circuits and transmission grid connection. The wind turbine energy support tower mounted solar array, pointed due South, provides about 25 KW of electrical energy per tower either as a Direct Current (DC) feed, or through an Alternate Current (AC) feed matching the wind turbine generator output needs, or directly to the wind turbine tower step-up transformer.
