Module bracket 1 tilt design; To allow solar cells to receive as much solar energy as possible in a year, we have to choose an optimum dip for the solar module. The discussion on the optimum dip angle of solar modules is based on different regions. 2 wind-resistant design; in the solar street lamp system, one of the most important structural problems is wind-resistant design. Wind-resistant design is mainly divided into two large pieces, one for the battery support of the wind-resistant design, the second is the wind-resistant design of the lamp bar. The following two pieces are analyzed separately.
