Abstract

This study analyzes the performance of solar modules in an off-grid Solar Power Plant (PLTS) system in Lasiana, Kupang City. The off-grid system operates independently and is not connected to the main power grid, making it a vital solution for remote areas without electricity. The study aims to evaluate the energy conversion efficiency of solar modules and identify factors affecting performance, such as tilt angle, orientation, and weather conditions. It also assesses the stability and reliability of energy output under real operating conditions, including fluctuations in production, light intensity variations, and temperature effects. A quantitative approach was used, with data collected through literature review, observation, direct measurement, and documentation. Measurements were conducted over seven days, recording irradiance, panel temperature, voltage, and current hourly from 07:00 to 17:00. The results show that monocrystalline modules consistently generate higher power than polycrystalline modules at all tilt angles. A 17° tilt produced the highest output, indicating it is optimal for the test location. Monocrystalline efficiency ranged from 18–22%, while polycrystalline modules reached 15–17%. Although polycrystalline modules are more economical, monocrystalline modules deliver higher energy production per square meter, making them preferable for long-term investment. Both types of modules experienced performance degradation due to shading, dust, and material wear, emphasizing the need for regular maintenance. This study confirms that optimizing tilt angle and choosing appropriate module types are key to improving off-grid PLTS performance, providing a reliable energy solution for remote areas.
