Performance Analysis of a 150 WP Portable Solar Power Plant (PLTS) in the Tarutung District Area

Abstract

This study aims to analyze the performance of a 150-WP portable solar power plant (PLTS) in

Tarutung District. The analysis was conducted based on output power parameters, system

efficiency, and the influence of solar radiation intensity and environmental conditions. The

research method included measuring voltage, current, and power under daily operational

conditions. The results showed that the performance of the 150-WP portable PLTS was affected

by weather and the position of the solar modules. This study is expected to be a reference for

the use of portable PLTS in the area. The research results show that the solar panel voltage

(open circuit) is 18.85 V – 19.90 V, peak voltage (19.90 V) at 14:00 the highest light intensity

(49,200 Lux at 12:00) there is a correlation between the decrease in light intensity (caused by

the weather) and the decrease in panel voltage, when charging the battery (Close Circuit) the

battery voltage is lower than the panel voltage, the highest charging current (3.16A), May 23

there was a fluctuation due to cloudy conditions, when testing the load (battery discharge), the

total discharge time was 5.6 hours (experiment 1), 4.1 hours (experiment 2, and 3 hours

(experiment 3). These results indicate that the Off Grid PLTS in Tarutung District is very

feasible to be implemented both technically and environmentally
