Abstract

This research is conducted to examine the on-grid system to solar module and analyze the consequences of on-grid solar power plant implementation towards the daily electrical energy consumption. The data retrieval is conducted for three days, from 29th to 31st July 2020 and this research provides real-time data by considering the weather conditions of each day. According to the result, the solar module has an efficiency value of 15,13%. This value is lower than the nameplate due to the higher solar module surface temperature compared to the optimal operating temperature. Subsequently, based on the implementation impact analysis, it is stated that on-grid system implementation in the solar power plant could produce electrical energy of 4,32kWh. It is also found that the daily output of on-grid system implementation in solar power plant could operate the load of 1,86kWh and it could export the electrical energy to the grid of 2,46kWh. In this way, the system could operate load of 2,45kWh and export electrical energy of 1,87kWh to the grid on the weekend. Therefore, it can be concluded that solar power plant with on-grid system could export the electrical energy to the grid.
