Ground Screw Solar Mounting System

Product Overview

This ground screw solar mounting system combines hot-dip galvanized screw piles with anodized aluminum rails. The piles screw into the soil with standard rotary machinery — no excavation, no concrete curing time, and no spoil to remove.

Ground screws are immediately load-bearing after installation, which makes them ideal for projects with tight schedules or seasonal weather windows. They can be removed and reused, and work on slopes up to 30° with little terrain modification.

Key Features

• No concrete, no digging — screws install in minutes with rotary drive
• Immediate load capacity — racking can follow the pile crew same day
• Slope friendly — handles terrain up to 30° grade
• Removable and reusable — perfect for leased land and temporary plants
• HDG Q235B piles — 76-114 mm shafts, 1.0-3.0 m lengths
• Aluminum rail superstructure — pre-cut and pre-drilled per layout

Application Scenarios

This system fits buyers who need fast, reversible foundations:

• Fast-track solar farms — install through winter and rainy seasons
• Sloped or uneven land — minimal grading, piles compensate level
• Leased or temporary sites — full demount and soil restoration
• Frost-heave regions — deep embedment below frost line

Configuration Options

• Pile specification — Ø76 / Ø89 / Ø114 mm, length 1.0-3.0 m
• Flange type — single flange, double flange or nut top
• Rail system — AL6005-T5 rails with SS304 fasteners
• Tilt angle — 15° / 20° / 25° / 30°
• Top connection — flange plate or adjustable bracket
