<p>The invention refers to the field of photovoltaic (PV) systems for direct transformation of solar energy into electrical. The invention increases the efficiency of photovoltaic systems through controlling the working temperature of the modules (1). Continuous cooling is achieved through evenly moisturising the heated surface of the photovoltaic modules. A layer of felt or other textile (2) is used to transfer and evenly distribute the moisture over the entire surface of the module. They are either firmly pressed to the surface of the module by a net (3) or attached in an alternative way. Water is supplied to the layer of felt or other textile by a drop irrigation system with a reservoir (4) and compensated irrigation emitters with a fixed outflow. It periodically adds the appropriate quantities of water for achieving permanent working temperature of the photovoltaic modules.</p> |
