Abstract:
Solar power generation is becoming increasingly popular in both PV Farm and PV Rooftop. Another type of installations that is highly popular overseas is Floating Photovoltaic system (FPV). In Thailand, the FPV installation is not still implemented broadly. There have been the specific studies or researches in the relevant fields such as the electricity efficiency and the impact of the usage in that environment.
For this study, the prototype FPV prototype was installed in the Rama 9 reservoir area, Pathumthani. The study aims to analyze and evaluate of 50 kWp FPV system which consisted of 5 systems of 10 kWp FPV system. The Homer Energy simulation was used to compare the performance and the evaluation for the economics aspect.
It was found that the solar radiation of the FPV system was higher than the ground system at the average of 25.1 W/m2 or approximately higher up to 6.1%. Temperature on the PV panel and under the PV panel of the FPV system at the water depth of 10 levels (3-16 m.) is lower than the PV panel of the ground system from 0.2 degree to 1.8 degree. In term of the energy generation, the FPV system can produce more power up to 7.6%.
