Elementos de Sujeción Galvanizados (ESG) has developed a hot-dip galvanized ground screw for ground-mounted PV installations.
The screw has a metal structure with a spiral that is driven directly into the ground, eliminating the need for excavation or concrete foundations.
ESG said it works efficiently in different soil types and reduces environmental impact. The company also claimed that it offers fast, easy installation without heavy machinery or complex procedures.
ESG said the propeller is designed to withstand high loads.
“In a standard model, the minimum torque of the screw is 2,100 nm, so if we calculate that the weight of a sun table with 10 modules is 250 kg to 300 kg, the screw could support it perfectly,” a company spokesperson told P.v magazine.
ESG customized the ground screw design to project specifications, customizing materials, dimensions and features based on customer needs. The company also offers a hot-dip galvanized finish that meets the UNE EN ISO 1461 standard, ensuring corrosion resistance and durability for more than 30 years without maintenance.
“This method significantly reduces both installation time and costs while providing optimal stability and strength,” the spokesperson said. “Its robust design makes it an ideal solution for supporting solar panels and other lightweight infrastructure.”
