ABSTRACTThe research was aimed to improve Photovoltaic (PV) efficiency by using water as a coolant in the cooling system in order to reduce working temperature of PV. There were 2 experiments; spraying water on the front PV surface and dropping water on the front PV surface. 40 watts mono-crystalline silicon PV type was used in the experiment.
อุปกรณ์หลัก ๆ ของระบบ PVs มีดังนี้ - Solar Photovoltaic modules - Meters - Array mounting racks - Disconnects - Grounding equipment - Combiner box - Inverter - Battery bank (The system with Battery Back-up) - Charge Controller (The system with Battery Back-up) - Battery disconnect (The system with Battery Back-up)
