The support frame 203 is used to install the storage box 202 on the top of the vehicle body 1. The storage box 202 is used to fold and store the first placement plate 204 and the second placement plate 205 when solar energy collection is not needed. The telescopic assembly is used to adjust the distance between the first placement plate 204 and the storage box 202. A placement slot for installing the photovoltaic panel 207 is provided on the side facing the sun after the photovoltaic panel 207 is assembled. The photovoltaic panel 207 can be detachably connected to the first placement plate 204 and the second placement plate 205 by bolts.
