GM3 is the No.3 HDG solar ground structure design developed by PandaSolar, which is made of fully hot-dip galvanized steel.
The thickness of hot-dip galvanizing reaches 80μm, which meets the environmental conditions of most countries
The structural frame has continuous rows of holes, the installation fault tolerance rate is large, and the installation is simple and greatly reduces the construction cost.
GM3 HDG solar mounting system is usually use ground screw foundation, 1200mm, 1600mm, 1800mm or 2000mm height to meet different geological conditions.
Structural features:
- Ground screw foundation design: Ground screw with adjustable flange plate
- Quick installation
- Pre-assembled base and adjustable flange plate, both realize the front-rear-left-right of the aluminum mounting bracket is adjustable, which is very convenient for installation.
- Have different solar structure design for choose: N shape, VI shape and W shape

Installing Ground Screws: The first step in installing a ground mount solar system is to install the ground screws. These screws are used to anchor the support structure to the ground. The screws are drilled into the soil using specialized equipment. The depth of the screw depends on the soil type, and it must be sufficient to hold the weight of the entire system.


Installing Rails :After the beam and diagonal support pole are in place, attach the rail that will support the solar panels. The rail should be attached to the beam using brackets and bolts. Ensure that the rail is level before moving to the next step.
