The Consideration of Heat Reduction Hourly Schedule on Front Surface of Photovoltaic Module to Improve Efficiency


The efficiency of the Photovoltaic (PV) are depended on many things, one of them is the accumulative heat on the front surface which related to the operating temperature. The attempt to improve PV efficiency was carried out by reducing the heat on the front surface. The Monocrystalline silicon photovoltaic was used in the experiment. There were two sets of system, control system and test system. The control system was the PV that operated in normal condition. The test system was the PV that operated with the heat reduction equipment in which spraying water on the front surface. The results showed that the test system had better output than the control system in overall. The output was considerably different during 11 am to 2 pm. On the other hand, there were not much of the differences in the morning and late afternoon. The highest value of the improvement efficiency was 15%. It was shown that the time schedule of spraying water in order to reduce heat on the front surface of the PV could be arranged instead of having it ran all day long.
