Electricity Generation of the Water Weighted Sun Tracking System in Sirindhorn Solar Power Plant
The purpose of this research was to investigate and compare the electrical power generation between the water weighted sun tracking system and the fixed installation system of the 1 MW solar power plant at Sirindhorn Dam. Two types of photovoltaic cell used in the water weighted sun tracking system were considered: multi-crystalline silicon and amorphous silicon. The results proved that the multi-crystalline silicon type produced 20.58% and the amorphous silicon type produced 16.57% more electrical energy than those of the fixed installation system, respectively. Overall, the water weighted sun tracking system generated 300,934.11 kWh/year more than that of the fixed installation system. The cost of the water weighted sun tracking system was 8.04 million bath and the payback period was 2.44 years, which was considered an attractive investment.
