Abstract

This study simulated active photovoltaic thermal solar collectors (PV/T) for hot water production using TRNSYS. The PV/T collectors consist of the amorphous, monocrystalline and polycrystalline. The long-term performances for the glazed and unglazed PV/T collectors were also evaluated. In this simulation, the design parameters used were collector area of 4 m 2, collector slope angle of 15 degree and mass flow rate to the collector area ratio of 8–20 kg/hm 2. In addition the tank height between 0.9 m to 1.1 m for unglazed PV/T collectors and 0.9 m to 1 m for glazed collectors, as well as the storage tank volume between 200 and 300 L has been used. The climate parameters used were solar radiation levels range of 4–4.9 kWh/m 2, the mean ambient temperature in the range of 25–28 C. The results of the simulation indicated that there was an increase in solar fraction and electrical power output of the active PV/T hot water system.
