Description

Solar panel wind shelter

This creation relates to a solar panel device used in the field of photoelectric conversion power generation, especially it can be installed in conjunction with the known sun-tracking solar power generation device, using its existing motor to cooperate with the processing unit and control unit, according to the wind speed and direction of the wind field A wind shelter that automatically adjusts the posture and direction of the solar panel to avoid damage to the solar panel caused by excessive wind.

Under the international trend of demanding the use of green and clean energy, solar panels that generate electricity through photoelectric conversion have also become an important part of green energy. Generally speaking, the solar panel needs to be installed in an open area with sufficient sunlight or a place such as a roof, and a stable structural frame needs to be installed before the solar panel is set on the structural frame.

In order to avoid strong winds from damaging the solar panels, the known wind shelters are designed with steel cables and springs fixed to the ground or other stable structures at the four corners of the solar panels as a wind shelter, or a plurality of solar panels are arranged as fans. In the open or retracted form, a driver is provided to control the posture of the solar panel; when encountering strong wind, the driver adjusts the solar panel to a horizontal posture or folds to a fan-shaped posture with a smaller surface area.

However, there are following deficiencies in the aforementioned known solar panel wind-shielding mechanism:

1. The installation field of solar panels fixed on a stable structure is limited, and it needs to rely on a stable foundation surface or piling. It is not suitable for independent solar installations with a height of several meters. In addition, common stable structures used to fix solar power generation devices The body is too bulky.

2. When the solar panel is adjusted to a horizontal posture, there is still an upper limit of wind resistance. Therefore, when a solar power generation device encounters strong winds above a certain wind speed, it is necessary to adjust the solar panel from a horizontal posture to a folded posture. However, a solar power generation device folded into a fan shape There is no downwind design. If the same strong wind blows vertically to the fan surface, it will cause load on the structural connection due to the maximum force limit, and there is a possibility of damage.
