The invention discloses a PC solar panel. The PC solar panel comprises a hollow irregular plate body; the two side surfaces of the hollow irregular plate body are sealed; the hollow irregular plate body is provided with an upper plate surface, a lower plate surface, a left side surface, and a right side surface; the upper plate surface and the lower plate surface are respectively composed of horizontal base plates and connecting base plates which are arranged at intervals and are connected; the included angles of the connecting base plates with the horizontal base plates are controlled to be 5to 90 DEG; each pair of adjacent connecting base plates are symmetrically arranged on the two sides of a corresponding horizontal base plate; the horizontal base plate arranged in an odd number sequence and the horizontal base plates arranged in an even number sequence are arranged in two parallel planes respectively; reinforcing ribs are arranged in the hollow irregular plate body between the upper plate surface and the lower plate surface; the two ends of the upper plate surface and the two ends of the lower plate surface are combined via fusion to form sealing edges. Compared with the prior art, the PC solar panel possesses following advantages: the connection firmness among the PC solar panels is increased, rainwater discharging capacity is excellent, the compressive strength is higher than that of common PC solar panels, and the PC solar panel is solid and durable.
