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. Specify the drawing, steel grade, finish and the quantity you need.

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 IS 2062 E250, S235 / S355, ASTM A36 / A653, plain, painted, hot dip galvanised (85 µm to ASTM A123 / ISO 1461) or pre-galvanised.

Also known as

Ground Mountings are ground mount racking in the US, ground mounting systems in the UK and ground mount systems in Australia; in other languages they are impianto fotovoltaico a terra (Italian) and estructura fija (Spanish).

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. Galvanised steel suits the open site.

What are solar ground mountings called in other markets?

US suppliers call them ground mount racking, UK suppliers ground mounting systems and Australian suppliers ground mount systems. In Italian a ground-mounted array is an impianto fotovoltaico a terra, and in Spanish a fixed structure is 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-galvanised strip for purlins. Corona supplies the steel plain, painted, hot dip galvanised or pre-galvanised to the drawing.
