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. . The present invention relates to obtaining a solar panel (1), which occupies less space and enables higher efficiency in the generation of the electricity from the solar rays as compared to the conventional solar panel systems, owing to the spiral shape, especially the golden ratio-based spiral. . In photovoltaic project foundation engineering, spiral ground piles, with their advantages of "no excavation required, quick installation, and strong load-bearing capacity," have become a key alternative to traditional concrete foundations. They are particularly well-suited for photovoltaic. . You know, the solar industry's been buzzing about spiral column foundations since Q1 2025. With 72% of utility-scale projects in the US now adopting this method according to the 2025 SolarTech Installation Report, it's clear this isn't just another industry fad. The spiral blades adopt a multi-level gradient design. By arranging the panels in a circular,ascending spiral configuration,it efficiently captures sunlight from multiple angles through ut the day,enriching ve money and invest in cleaner energy.
