Technical Field

Solar energy has the advantages of abundant resources, longevity, wide distribution, safety, cleanliness and reliable technology. Since solar energy can be converted into many other forms of energy, its application range is very wide. To obtain electricity from solar energy, it needs to be achieved through photoelectric conversion of solar cells.

[0003] Most existing photovoltaic systems first set up the support system, and then install the photovoltaic panel components from the top of the support system.
