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)
This paper presents the evaluation results of the performance ratio (PR) of different photovoltaic (PV) module technologies by installing the six generated PV systems onto roof in Thailand with records data of one year period. It was found that a-Si:H PV system has a highest initial PR of 82.2%, while mono c-Si PV system has a lowest PR of 68.9%.
