Since the system has been operational until now, the PLTS at the LKC wallet dhuafa Palembang clinic has never been analyzed on the system's performance, so it is not yet known whether this system is working well or not. The aim of this research is to analyze the performance of PLTS at the LKC Dompet Dhuafa Palembang clinic against variations in inductive and resistive loads. This research has 4 research stages, namely: 1). Literature study. 2). tool testing is carried out. 3). Data collection measurements. 4). Data analysis. From this research, the results obtained from testing tools and measuring data on PLTS performance at the LKC wallet dhuafa Palembang clinic with variations in inductive and resistive loads, when measuring the highest inductive input power was 449.8 W, the resulting efficiency was 83% at 12 :00, while the resistive input power is 546 W, the resulting efficiency is 80% from 12:00 to 15:00. From the research that has been carried out, the inductive load efficiency calculation results are 83% at 12:00 and the resistive load efficiency calculation results are 80% from 12:00 to 15:00. So it can be concluded that the performance of PLTS at the LKC Dhompet Dhuafa Palembang clinic is optimal in terms of load calculations.
Humans are almost inseparable from electrical energy in everyday life. This is due to the increase in population which causes an increase in demand for electrical energy. However, the increase in demand for electrical energy is inversely proportional to the energy needed to be converted into electrical energy, where the use of electrical energy still comes from non-renewable energy sources, namely fossil energy and can run out over time, and it takes a very long time for the energy to These fossils are available and can be reused. Utilization of new and renewable energy is a very important issue in efforts to reduce the use of fossil energy which is currently increasingly depleting.
