The roof structure for solar power generation is convenient for fixing the solar panel body through the provided buffer springs, fixing plates, shells, mounting rods, buffer plates and connecting springs, and at the same time, buffers and reduces shock of the solar panel body. When the solar roof frame is vibrated by external force, it can buffer the two solar panel bodies, thereby improving the stability of the fixation of the solar panel body.

At the same time, when the surface temperature of the photovoltaic panel 9 is too high, the servo motor 13 can be controlled by the controller 23 to start and drive the connecting rod 5 to rotate, thereby driving the first bevel gear 121 to synchronize. The first bevel gear 121 rotates, driving the second bevel gear 124 to rotate, thereby driving the spiral blade 128 to rotate, thereby accelerating the air flow to continuously cool the surface of the photovoltaic panel 9, thereby cooling its surface and preventing the surface temperature from being too high, which will lead to a decrease in photoelectric conversion efficiency. The connection is made through the spring 14 so that when there is wind and rain outside, the photovoltaic panel 9 can be blown to vibrate and shake in the limit groove 8. When the photovoltaic panel 9 moves, the spring 14 is driven to compress or stretch, causing the piezoelectric piece 15 to undergo periodic mechanical deformation. The deformation causes the internal polarization of the piezoelectric piece 15, and the surface generates an electric charge to form an AC voltage signal, which is then rectified and filtered by the converter to form a DC power, and finally stored in the rechargeable battery 16. This process realizes the conversion of dynamic mechanical energy of the photovoltaic panel 9 into electrical energy, providing auxiliary power supply for the system, and can power the sensor components and emergency power supply. The process of storing electricity between the photovoltaic panel 9 and the energy storage battery 24 through wires and the charge and discharge control unit is essentially to store the electricity generated by the photovoltaic panel 9 safely in the energy storage battery 24 after regulation, thereby realizing rooftop photovoltaic power supply.
