[0016] Compared with the prior art, the utility model has at least the following technical effects or advantages:

[0017] 1. Existing containerized photovoltaic (PV) support systems include radar-type, wave-type, and vertically folding types. Radar-type systems can achieve fully automatic opening and closing of solar panels through hydraulic control; however, their structure is complex and costly. When the number of solar panels reaches a certain threshold, stability decreases due to material limitations. Furthermore, the fan-shaped section of the radar-type solar panel support is typically supported by a hydraulic lifting turntable, leaving the entire section suspended in the air, making it sensitive to wind loads, thus limiting the number of solar panels that can be installed. Wave-type and vertically folding types, on the other hand, can significantly increase the loading density of containers, allowing for the placement of a large number of solar panels. They are also simple to manufacture and inexpensive; however, they require manual operation, resulting in lengthy initial setups, especially for centralized array configurations, making rapid deployment impossible.

[0018] This invention uses a rope wheel drive to achieve a stepped unfolding of solar panels, which can overcome the shortcomings of radar-type, wave-type, and vertically folding types, while meeting the requirements of high loading density, automated expansion and contraction, and stability, achieving a good balance.

[0019] 2. The two sets of identical solar panel telescopic support assemblies of this utility model are symmetrically installed on both sides of the main frame. This symmetrical layout ensures even distribution of loads (wind pressure, snow load, and self-weight), avoiding stress concentration on one side, reducing the risk of support twisting or overturning, minimizing turbulence effects, achieving uniform illumination, and facilitating installation and maintenance. Rollers are provided at the top and bottom of each platform, with the top and bottom pulleys and rails sharing the load, avoiding stress concentration at a single point and improving the overall structure's torsional and bending resistance.

[0020] 3. This utility model is equipped with a movable support assembly. When unfolded, the movable support assembly moves synchronously with the corresponding solar panel telescopic bracket. After unfolding, the electric push rod drives the movable support assembly to extend, so that the running wheels below contact the ground, thus preventing the solar panel telescopic bracket from being cantilevered. When retracted, the electric push rod shortens, causing the running wheels to leave the ground. Attached Figure Description
