Solar panel with a coolant vapor pressure driving system

Abstract

Coolant vapor pressure is used to generate a push force to adjust the azimuth angle of a solar panel without using a dedicated power supply.

1 . A solar panel with a coolant vapor pressure driving system, comprising:
 a spring cylinder, coupled to move the solar panel and having an expansion chamber;   a coolant tank, coupled to the expansion chamber for giving a higher vapor pressure when the temperature increases, and for giving a lower vapor pressure when the temperature decreases; and.   a control unit, coupled to the coolant tank, for controlling the flow of the coolant vapor between the coolant tank and the expansion chamber according to predetermined conditions.   
     
     
         2 . A solar panel with a coolant vapor pressure driving system as claimed in  claim 1 , further comprising: an electric valve, coupled between the coolant tank and the expansion chamber for turning on/off the flow of the coolant vapor. 
     
     
         3 . A solar panel with a coolant vapor pressure driving system as claimed in  claim 1 , further comprising: a pressure valve, coupled between the coolant tank and the expansion chamber as a flow regulator for the flow of the coolant vapor. 
     
     
         4 . A solar panel with a coolant vapor pressure driving system as claimed in  claim 1 , wherein said flow of the coolant vapor is to let the vapor enter the expansion chamber. 
     
     
         5 . A solar panel with a coolant vapor pressure driving system as claimed in  claim 1 , wherein said flow of the coolant vapor is to let the vapor go back to the coolant tank.
