Abstract:
Aiming the improvement of usage of solar thermal energy PV modules is widely used throughout the world. Due to the lack of desired level efficiency the numerous researches are carried out to escalate the output of PV modules one of the form of developed PV modules is PV/T solar system. The temperature of PV module increases while absorbing solar radiation causing the decrease of electrical output after certain level. The hybrid Photovoltaic/Thermal (PV/T) solar system enhances the output of PV module facility the harvest of both thermal and electrical energy using the same solar radiation absorbed by the same surface area. In this experiment the design of PV/T dual system is developed, using both air and water circulation as heat extraction medium modifying the air channel. The shape of painted black ribbed surfaces at the bottom of air channel has been used as trapezoidal, Saw tooth backward ,Saw tooth forward and Flat plate as reference. The capacity of all set up is similar and having same dimensions. The process of natural convection is applied to circulate the air and water to increase the system efficiency. The variation in the net output is studied due the difference of air channel.
