Abstract :
Unit Pembangkit Muara Karang has started to make an energy transition as evidenced by the power plant which is not only a Steam Power Plant (PLTU), but also has developed a Solar Power Plant (PLTS). PLTS in Administration Building has long been installed since 2016 and continues until now. During the 6 years of operation, the PLTS experienced a decrease in the performance ratio and efficiency value, so maintenance was needed. This study aims to optimize the On Grid PLTS with a capacity of 15 kWp at the Muara Karang Generating Unit, in order to find out whether there is an increase or not after maintenance. The research model used is a single line diagram of PLTS rooftop On Grid, then the calculations can be done manually. The results of measurements and calculations obtained that the average value of efficiency before maintenance is 12.96% slot A and 12.62% slot B. While the average efficiency value obtained after maintenance is 13.10% slot A and 13.02% slot B. Efficiency value increased after maintenance, namely 0.14% for slot A and 0.4% for slot B. The ratio of performance before and after maintenance was 84% and 91%, respectively. The value of the performance ratio has increased after maintenance by 7%. The decrease in efficiency and performance ratio is caused by the small value of the intensity of solar radiation absorbed by the solar panels, the influence of temperature, loose cable connectors, shadows, and dirt that covers the solar panels.
