Photovoltaic support and photovoltaic system

The invention provides a photovoltaic support and a photovoltaic system, the photovoltaic support comprises a base, a first support part and a second support part, the first support part and the second support part are arranged on the base, the first support part is located on the side of the base, the second support part is located above the base, and the highest position of the first support part is lower than the lowest position of the second support part. According to the photovoltaic support, due to the fact that the heights of the two supporting parts of the photovoltaic support are different, the photovoltaic assemblies supported by the photovoltaic support are arranged in a staggered mode in the height direction, then flowing air can smoothly enter the lower portions of the photovoltaic assemblies, the heat dissipation performance of a photovoltaic system is improved, and the photovoltaic support is simple in structure and lower in cost. 本发明提供了一种光伏支架及光伏系统，其中光伏支架包括基座，设置在基座上的第一支撑部和第二支撑部，第一支撑部位于在基座的侧方，第二
