Solar rail mounting system

A solar photovoltaic (PV) rail mounting system, comprising:

• a mounting base comprising a fixed base (1) for connection to ground and a mounting section (3) connected to a rail clamp (9), wherein the fixed base (1) is equipped with multiple pre-installed screw sections (4) arranged around its perimeter, each containing threading matching installation screws (2);
• a mid clamp consisting of an upper pressing block (17) and a fixed connecting block (18), wherein the upper pressing block and the fixed connecting block are connected via a sleeve-type connection;
• wherein the upper pressing block (17) includes a top PV panel press (20) and two sleeve rods (21), wherein the fixed connecting block (18) has sleeve slots matching the two sleeve rods (21), wherein a spring I (25) is positioned between the two sleeve rods (21) and secured by bolt III (19), providing an elastic height adjustment for PV panel installation, wherein both the upper pressing block (17) and the fixed connecting block (18) are equipped with grounding pins;
• an end clamp comprising a fixed section (29), a movable section (30), and a tension wire (31), wherein the fixed section (29) includes an upper spherical connection slot (33) and a lower rail connection section, wherein the movable section (30) consists of a frame pressing plate (34) and a spherical protrusion (35) that is movably connected to the spherical connection slot (33), wherein the fixed section (29) and the movable section (30) are connected by bolt IV (32), with the tension wire (31) featuring a pull ring at the connection end that loops around bolt IV (32) for secure attachment;
• a wind deflector clamp comprising an upper wind deflector fixture (40), a lower wind deflector fixture (41), and a wind deflector pressing block (42), wherein one side of the upper wind deflector fixture (40) is fitted with an installation pressing plate (43), and the other side features a strip-shaped guide rail slot (44) for snap-fit connection with the wind deflector (45), allowing for horizontal movement of the wind deflector (45) within the slot, wherein the upper wind deflector fixture (40) and the lower wind deflector fixture (41) are connected via an adjustable bolt I (46), forming an installation groove fixed to the solar PV panel frame, wherein the wind deflector pressing block (42) is attached to the upper wind deflector fixture (40) via bolt II (47), with one side flush with the installation pressing plate (43) and the other side equipped with a pressing strip (51) to secure the wind deflector (45).
