Photovoltaic (PV) modules are devices able to convert solar radiation directly into electricity. An important characteristic to observe is the solar cells’ efficiency tends to decrease as the temperature rises. This study has developed an adaptable cooling system for flat-plate PV modules. The objective is to absorb heat from solar cells, reducing efficiency losses and use this energy to warm up water. The result was an hybrid photovoltaic/thermal (PV-T) equipment. A prototype for a 1470mm x 680mm and 140W PV module was manufactured to measure the temperature reduction on solar cells, the influence of this reduction on its efficiency and also the temperature rise of water in the thermal system.
