ANNUAL EXERGY EVALUATION ON PHOTOVOLTAIC-THERMAL HYBRID COLLECTOR

In this study, we designed and constructed a photovoltaic-thermal hybr id collector on our campus. The collector consisted of a liquid heatin g flat-plate solar collector with mono-Si PV cells on substrate of non -selective aluminum absorber plate, The collector area was 1.3 x 0.5 m [1]. Since electrical and thermal energy are different in nature, it is necessary to take into account the nature of the energy in evaluati ng or comparing them. For this, we adopted concepts based on the exerg y theory. From our annual experimental evaluation based on exergy, we are concluding that the PV/T collector can produce higher output densi ty than a unit PV module or liquid heating Bat-plate solar collector.
