The classification and characteristics of ground photovoltaic bracket systems
The ground photovoltaic bracket system is a mounting system for solar panels installed on the ground. Different ground terrains require different solar installation systems. Choosing the appropriate solar bracket based on local conditions is crucial for ensuring the efficient operation of the entire photovoltaic system. Today, we will introduce the classification and characteristics of ground photovoltaic bracket systems.
Cement Foundation Ground Bracket
If the installation site is not suitable for insert-type piles, a cement foundation can be constructed to place the ground photovoltaic bracket on top, secured with bolts. Characteristics: The foundation can be buried relatively shallowly, but the excavation and backfill volumes are considerable, requiring a significant amount of concrete.
Hammer-in Pile Ground Bracket
Using a pile driver, C-shaped steel, H-shaped steel, or other structural steel is driven directly into the ground. This installation method is very simple but has poor pull-out resistance. Characteristics: Fast installation speed, strong adaptability; cost-effective; not restricted by seasonal temperature; easy to remove piles without affecting the reuse of the installation site.
Helical Pile Ground Bracket
This type can meet various engineering requirements such as compressive, tensile, and lateral force resistance. It is quick and convenient to install, significantly shortening the construction period, environmentally friendly, and can be implemented in various climatic conditions, including winter in northern regions. It is also easy to relocate and recycle.
Precast Pile Foundation Ground Bracket
Precast piles are made from various materials in a factory or on-site, and are driven, pressed, or embedded into the soil using piling equipment. Characteristics: Can be mass-produced, quick installation speed, no excavation or backfill required, only simple leveling needed. However, when static pressure or hammering equipment compresses the pile into the soil, the pile is prone to breakage, requiring reinforcement with a rebar mesh at the pile top, which increases costs and makes verticality difficult to guarantee.
