It is equipped with guide rail, and liftable shutter door is installed on guide rail, bracket, photovoltaic module and air-conditioning are located at shutter door and room side
In the confined space that wall is formed, which divides the room into two parts by setting shutter door, realizes photovoltaic module surrounding air
Vertiginous purpose shortens the time entirely tested and achievees the effect that rapidly and uniformly to change photovoltaic module temperature, increases
Big efficiency, and it is at low cost, but the patent has the disadvantage that the bracket for placing photovoltaic module does not have adjustability, it cannot
Photovoltaic module is put by required angle, is unable to test temperature coefficient of the photovoltaic module under different lighting angles, is operated
And it is inconvenient.
