New hot-dip galvanized screw for ground-mounted PV – pv journal International

From pv journal in Spain

Elementos de Sujeción Galvanizados (ESG) has developed a hot-dip galvanized floor screw for ground-mounted PV vegetation.

The screw has a metallic construction with a helix that drives straight into the bottom, eliminating the necessity for excavation or concrete foundations.

ESG says it really works successfully on a wide range of soil sorts and minimizes environmental affect. The firm additionally claims that it affords fast, straightforward set up with out heavy equipment or difficult procedures.

ESG stated the screw was designed to resist excessive masses.

“In an ordinary mannequin, the minimal torque of the screw is 2,100 nm, so if we calculate that the burden of a photo voltaic desk with 10 modules is 250 kg to 300 kg, the screw absolutely helps it,” an organization spokesperson instructed p.v journal.

ESG adapts its floor screw design to fulfill venture specs, adjusting supplies, dimensions, and traits based mostly on consumer wants. The firm additionally affords a hot-dip galvanizing end that complies with the UNE EN ISO 1461 customary, which ensures corrosion resistance and sturdiness for greater than 30 years with out upkeep.

“This technique permits for a big discount in set up time and value whereas offering optimum energy and sturdiness,” the spokesperson stated. “Its sturdy design makes it a really perfect answer for supporting photo voltaic panels and different light-weight infrastructure.”
