Abstract

Availability of solar energy as a renewable energy source is very abundant and inexhaustible. Solar water heater is an equipment that utilizes solar energy as a source of energy. The thermal performance of a solar water heater system using absorber plate with phase change material (PCM) as thermal energy storage is presented in this study. Two design of solar water heater collectors with absorber plate variations, i.e. an absorber plate with PCM storage and absorber plate without PCM storage were investigated experimentally and numerically simulation. First, the material properties of paraffin wax as PCM storage was analized analyticaly. Every shape model of solar water heater systems were imported and simulated at three variations of constant solar radiation, i.e. 400 W/m2, 700 W/m2, and 1000 W/m2. The simulation using a computational fluid dynamic (CFD) fluent software. The results showed that the average collector efficiency between absorber plate with and without PCM storage is 70.98 % using experimental study and 67.73 % using numerical simulation study.

Abstract

Photovoltaic (PV) systems are a promising renewable energy source due to their ease of installation, eco-friendliness, and abundant solar radiation availability. Indonesia has a theoretical potential of 4.625 kWh/m² and a practical potential of 3.767 kWh/kWp; however, as of September 2021, its installed capacity was only 194 MW. Land constraints have led to the development of floating PV systems, which reduce land usage and enhance module efficiency due to lower temperatures above water. Nonetheless, PV systems face challenges from solar radiation intermittency, influenced by cloud opacity, causing output power fluctuations. This study maps cloud opacity patterns on Kodingareng Island based on dry and rainy seasons using 2020 BMKG data. Results indicate that output power during the dry season is more stable than in the rainy season due to lower cloud cover. Conversely, thick cloud cover during the rainy season reduces solar radiation reaching PV modules, resulting in fluctuating power output. Thus, floating PV systems demonstrate better energy availability during the dry season. This study highlights the importance of understanding cloud opacity patterns in planning floating PV systems to address the challenges of solar radiation intermittency.

Abstract

Solar water heater technology is increasingly in demand by the wider community, this has led to an increasing number of research related to solar water heaters. The working efficiency of a thermosyphon solar water heater with the integration of heat storage materials is presented in this study. Heat absorbing collectors with varying thicknesses of paraffin wax PCM as the heat storage material are modeled and then the performance calculated theoritically. The variations thickness of the heat storage material are 6 mm, 10 mm, and 15 mm, respectively. The theoritically calculation conducted based on experimental data collection with varying constant solar radiation. The results of this study show that the working efficiency of the heat absorbing collector with a PCM thickness of 15 mm is greater when compared to thicknesses of 10 mm and 6 mm or collectors without heat storage material with an average efficiency of 67.49%.
