Ground Mountings

Ground Mountings are fixed-tilt steel structures for ground-mounted solar arrays: posts set in the ground, inclined rafters, purlins that carry the module rails, and bracing, made from cold-formed sections and fabrication to the array drawing.

Function

Holds the modules at the design tilt

The structure carries rows of solar modules at a fixed angle above the ground, row after row across the site.

Made to drawing

Posts, rafters, purlins, bracing

Each part is cut, punched and galvanized to the array designer's drawing, so the kit goes together with bolts on site.

Product form

Posts 60 to 114 mm

Round tube posts of 60, 75, 89 and 114 mm or C and sigma sections in ASTM A36 / A653, S235 / S355 grades, plain, painted, hot dip galvanized to ASTM A123 (85 µm) or pre-galvanized.

Also known as

Also called ground mount racking in the US. Spanish-speaking crews call it estructura fija.

US English: ground mount racking
Español (US): estructura fija

How it works

Posts in, rafters on, purlins across

Posts are driven, screwed or concreted into the ground in rows. Rafters are bolted to the post heads at the design tilt, and purlins are bolted across the rafters. Bracing ties the frame front to back, and the module rails and clamps are fixed to the purlins.

Common applications

Where it is used.

Application

Utility-scale solar farms

Large arrays repeat one table design across the site. Every part is made and galvanized to the same drawing.

Application

Commercial and industrial sites

Factories and campuses put arrays on spare land beside their buildings. Tables are sized to the plot.

Application

Farms

Farm arrays stand on pasture or unused ground. Galvanized steel suits the open site.

What else are solar ground mountings called?

US suppliers call them ground mount racking. In Spanish a fixed structure is called an estructura fija.

What galvanizing do solar ground-mount structures get?

Array designers usually specify hot dip galvanizing to ASTM A123 or ISO 1461, often with an 85 µm minimum zinc layer, or pre-galvanized strip for purlins. GV supplies the steel plain, painted, hot dip galvanized or pre-galvanized to the drawing.
