When selecting the quantity and size of ground screws, the impact of various loads (wind load, snow load, earthquake load, etc.) on ground piles must be considered, and appropriate ground piles must be selected based on the soil hardness obtained from prior soil investigation and site surveys. 

The following table gives the pull-out force and compression force of spiral ground piles of different lengths under different soil conditions as a reference.

Q1: What is a galvanized ground screw in a solar ground mounting system?
A1: A galvanized ground screw is a steel foundation anchor used to secure solar mounting structures to the ground. It eliminates the need for concrete foundations, allowing quick and stable installation of solar panels on various terrains.

Q2: Why choose galvanized ground screws for solar installations?
A2: Galvanized ground screws offer excellent corrosion resistance, strong load capacity, and easy installation. They are ideal for solar farms, open-field PV projects, and uneven ground conditions.

Q3: How long does a galvanized ground screw last?
A3: Thanks to the hot-dip galvanization process, ground screws typically last over 25 years. The zinc coating protects the steel from rust and oxidation, ensuring long-term durability in outdoor environments.

Q4: Can galvanized ground screws be used in rocky or soft soil conditions?
A4: Yes. Different models of ground screws are available for various soil types — including sandy, clay, and rocky ground. Our engineers can provide soil testing and recommend the most suitable design.
