The ground screw pile is a core foundation component for solar photovoltaic (PV) systems installed on the ground. It features advantages such as simple installation, no need for concrete pouring, short construction period, and minimal damage to the ground environment. This guide details the standard installation process, required tools, safety precautions, and quality inspection criteria for solar ground screw piles to ensure the stability and reliability of the PV system foundation.

- Verticality Parameter: The vertical deviation of each ground screw pile shall not exceed 1‰ of the pile length, which shall be detected with a theodolite;
- Embedding Depth Parameter: The embedding depth of the pile body shall be in line with the design requirements, with an allowable deviation of ±50mm, and shall be checked with a tape measure;
- Spacing and Position Parameters: The spacing between adjacent piles shall meet the design standards, and the horizontal position deviation of the pile body shall not exceed ±100mm;
- Pile Body Integrity Parameter: The surface of the ground screw pile shall be free from damage, deformation or corrosion. If any defects are found, the pile body must be replaced in a timely manner.

Application

Common Problems	Causes	Solutions
Pile body deviation during driving	Uneven soil hardness, improper positioning, or unstable pile driver operation	Stop driving immediately, pull out the pile and reposition it; adjust the pile driver to ensure stable operation; pre-treat the uneven soil (e.g., level the soil surface)
Difficult to drive the pile into the ground	Hard soil, gravel in the soil, or insufficient power of the pile driver	Replace with a higher-power pile driver (e.g., hydraulic pile driver); pre-drill a small hole in the soil to reduce resistance; remove large gravel in the soil in advance
Pile body deformation or damage	Collision with hard objects during transportation or installation, or excessive driving force	Replace the deformed or damaged pile body; avoid collision during transportation and installation; control the driving force of the pile driver to be within the allowable range
Insufficient bearing capacity of the pile body	Insufficient embedding depth, inappropriate pile type selection, or poor soil bearing capacity	Increase the embedding depth of the pile body; replace with a multi-helix ground screw pile with stronger bearing capacity; pre-treat the soil (e.g., compact the soil)
