Any tilting or sinking of solar panels can reduce power generation efficiency and may introduce safety risks, making it essential to reinforce piling stability.
A pile driven foundation transfers all solar mounting structural loads — wind uplift, wind lateral force, gravity, and seismic — directly into the soil through a steel section driven to design embedment depth, relying on the soil-steel interface to develop skin friction resistance.
This article focuses on the core characteristics of spiral ground piles, detailing their performance indicators, material selection, scenario adaptation solutions, and key construction quality control points, providing a practical guide for photovoltaic project foundation design.
