Cells are immersed in a patented liquid cooling system which ensures low air temperature, high operating performance and a longer duration. The liquid also acts as a cushion that protects the floating cells from mechanical failures, in case of vibration and kinetic shock during transport, assembly or in the presence of hail or sand storms. The liquid also provides a more efficient heat dissipation, preventing any cracks related to "hot spots" of the panels due to deposit of leaves, mud or bird faeces.
