A typical solar tracker bearing of 100 square would need to accommodate at least 1000-1500 Kgs of vertical load. The second criterion is friction. The use of friction reducing additives is required in making solar tracker bearings, as it greatly enhances efficiency. Experience has shown us that there is a balance needed here.
The solar tracker bearing clamps around the square tube on which the panels are fixed. The tracker rotates the square pipe and the bearing’s job is to allow for this rotation with minimal friction. For the most part, a solar tracker bearing needs to match the size of standard square tubes.
HALS would allow the solar tracker bearing to have a life of 25-30 years, which is what is required when considering a solar project. While smaller projects may opt for machining, it is our belief that an injection moulded part is most suitable for solar tracker bearings.
Ballasted solar systems do not require anchorage to the supporting surface, making them a versatile choice for different construction types. However, it is still essential to ensure proper weight distribution within the ballasted system to maintain stability and avoid any damage to the solar panels.
Bearings should let the tracker move smoothly, with minimal friction, when the motor, slew drive, or actuator pushes it. Range of motion. The bearings should let the tracker move as far as possible in each direction – east and west – so it can follow the sun and produce as much energy as possible.
Design considerations for solar panel mounting structures include factors related to structural integrity, efficiency, safety, and aesthetics. This can involve wind, snow, and seismic loads, ventilation, drainage, panel orientation, and spacing, as well as grounding and electrical components.
