Construction method and system of a solar cell power plant
A method for constructing a solar power plant on various terrains involves installing reinforced concrete piles to form a lattice on the ground or foreshore, building a lattice-type truss with steel beams and longitudinal rails, and mounting solar panels whose inclinations can adjust 360 degrees via length-variable connectors. This setup allows for easy maintenance and replacement of panels using a track vehicle, enhancing system durability and reducing construction costs. The design negates extensive land leveling, offering a cost-effective, typhoon-resistant structure that minimizes the need for terrain modification, streamlining the installation of large-scale solar facilities.
