Solar powered roof ventilation system

Abstract

A solar-powered ventilation system may be mounted to a building. Through the use of internal dampers and destratification intake doors, the system is able to cool the inside of buildings by way of hot-air venting or cold-air induction methods. Further, the system may also be configured in a combinatory manner, allowing the building to be cooled by the simultaneous use of hot air venting and cold-air induction methods.

What is claimed is: 
     
         1 . A self-contained solar-powered ventilation system unit for mounting on a building, the system comprising:
 a solar panel structured to convert solar energy to electrical power for use by the ventilation system;   a battery coupled to the solar panel and structured to store the electrical power generated by the solar panel;   a fan motor structured to use the electrical power generated by the solar panel to operate a fan to move air through the air path;   at least one damper structured to prevent or allow air from flowing through the air path by changing position; and   an electric damper actuator coupled to the battery and structured to change the position of the at least one damper.
