A LV/MV transformer is typically at the base or inside the tower to step-up the voltage for array interconnection anywhere from 11kV to 33kV

. This high voltage is needed to transport the electricity efficiently over long distances to the grid connection point. The transformer takes the lower voltage output from the solar panels and increases it to the required level for distribution. The transformer also provides isolation and protection for the solar array and the grid. A low voltage switchgear is usually installed next to the transformer to control the power flow and protect the system in case of faults or overloads. The LV/MV transformer is an essential component of a solar power plant, enabling efficient and safe energy transmission to the grid.
