Thermosiphonic hybrid PV/T solar systems

Thermosiphon solar water heaters and Photovoltaic (PV) devices are well known solar systems that provide heat and electricity, | respectively. In this work, these two systems are combined into a hybrid Photovoltaic/Thermal (PV/T) solar system which can simultaneously provide electricity and heat, thus achieving a higher conversion rate of the absorbed solar radiation than standard PV modules. When properly designed, PV/T systems can extract heat from PV modules which can be used to heat water or air. By ! doing so the operating temperature of PV modules is reduced, which is beneficial, as it keeps their electrical efficiency at a sufficient level. In this paper, the design considerations and experimental results of a thermosiphonic hybrid PV/T solar system are presented. The electrical and thermal energy output for a pc-Si PV/T module type under the climatic conditions of Patras are presented.

The contribution of solar energy is expected to be essential for the next years towards the EC aim of 12% by RES until the year 2010. In this paper a scenario towards a wider application of them in Greece is presented and innovative solar energy devices that have been developed in Physices Department of University of Patras and aim to an improved integration of solar energy systems on buildinds are included. Energy, cost and aesthetic aspects of the investigated solar energy systems are briefly presented and perspectives for their wide application are discussed.
