Steel piles (usually H-beams or C-sections) are driven vertically into the soil by a hydraulic piling machine without any concrete. The mounting rails are then fixed directly on the top of the piles. This method is effective for driving piles into dense or compact soils, ensuring a secure and stable foundation. However. . PV farms or photovoltaic Solar Panel Farms as they are also known are designed and built to gather energy from the sun's rays, which is transformed into electricity. Poor quality execution can result in damage to the plant and to the building and can present a risk to people.
