Problems solved by technology

Among them, the single-arm structure is light in weight and saves consumables, but the supporting effect is average, while the preparation process of the double-arm structure is relatively complicated, the amount of consumables is large, the quality of the card slot is large, and the upper panel will block the solar cells, which will affect the solar cells to a certain extent. The effective light-receiving area of ​​the module reduces its photoelectric conversion efficiency
