This utility model discloses a wind-resistant and stable photovoltaic (PV) support and a PV fixing system. The PV support includes PHC pipe piles and a support structure fixed to the PHC pipe piles. The support structure includes a diagonal beam, a front column, a rear column, a front diagonal support, a rear diagonal support, an upper clamp, and a lower clamp. The front and rear columns are fixed to both sides of the PHC pipe piles by the upper and lower clamps. A Z-shaped crossbeam, diagonal brace, and crossarm are fixed between the front and rear columns. A first support block is fixed between the crossarm and the upper clamp, and a second support block is fixed between the upper and lower clamps. The first and second support blocks are located on both sides of the PHC pipe piles. The diagonal beam is used to fix the PV panels. The front diagonal support, rear diagonal support, and diagonal beam are arranged in a triangular pattern. This utility model, by setting support blocks and reinforcing ribs, enables the PV support to withstand greater wind force, saves 20% of steel material, and reduces weight.
