Abstract

This research was initiated by the idea of making building materials and/or building components/parts into sources of electrical energy, especially on the roof and walls of buildings. Building roofs and walls have the potential as a means of utilizing solar energy into electrical energy with a thermoelectric generator (TEG) converter. Therefore, the aim of this research is to obtain the performance of thermoelectric generators with series and parallel circuits as power generators on the walls of building models. The research methodology used is experimental which begins with designing research equipment consisting of a building model frame and a thermoelectric system arrangement. In this research, a series and parallel TEG circuit was compared. Both sets of TEG systems have aluminum attached to absorb heat from the sun on the hot side of the TEG and a water block made of aluminum is attached to the cold side of the TEG. Styrofoam is attached to the surrounding sides between the TEG modules as a thermal insulator. The parameters in this research consist of independent variables, moderator variables and dependent variables. The independent variables are the temperature of the hot side of the TEG and the temperature of the cold side of the TEG. The moderator variables are good water temperature, water discharge, water temperature entering the waterblock, water temperature leaving the waterblock. Meanwhile, the dependent variables are electric current strength, electric voltage, electric power, and TEG efficiency. The research results showed that the maximum electric current was 0.54 A and the maximum electric voltage was 0.08 V. The maximum electric power as output power from the TEG system was 0.0432 W and the average thermoelectric efficiency was 4%.

Abstract

Solar energy is energy that is classified as new and renewable energy. Utilization of solar radiation energy into clean electrical energy through solar panels. This study uses solar panels that are integrated with thermoelectric modules. This study aims to improve the performance of solar panels that have been hybridized with thermoelectric generators arranged in parallel. The method used in this study is experimental, starting with the design and manufacture of research tools. The research tool is a model of a building whose roof has a slope of 30o and is equipped with a hybrid system consisting of a set of solar panels, a thermoelectric generator, and a cooling system that allows the thermoelectric generator to be cooled. The hybrid device includes two different systems. The first system, a solar panel with a thermoelectric generator, is assembled using a separate rack, so the solar panel with a thermoelectric generator is located on a separate rack. The second system, solar panels and thermoelectric generators are assembled into an integrated circuit on the same rack. The variables measured in this study are the intensity of sunlight, ambient temperature, solar panel temperature (top and bottom), water temperature, wind speed, humidity, thermoelectric generator temperature, open circuit voltage (Voc), maximum voltage, short circuit current (Isc), and maximum current. The research results show that the efficiency of hybridization with a combined rack system has an average of 18.3%, while with a separate rack system the efficiency is lower with an average of 14.7%. Based on this, hybridization using a fused rack system is more efficient than a separate rack system.

Abstract

Building as a source of energy is not something extraordinary, as in BIPV (building-integrated photovoltaic) technology. Likewise, making buildings a NZEB (net zero energy building) has become a necessity in the context of saving energy use. One energy converter that has been used in buildings is PLTS or solar cells, which is a power plant that converts solar radiation into electrical energy (photovoltaic system). The conversion process is influenced by the direction of sunlight coming to the position of the solar cells that are placed on the roof of the building. This study aims to determine the effect of the direction of sunlight on the performance of solar cells, so that it is obtained from the right direction of sunlight. Solar cells are exposed to the north, east and west. The input parameters for each direction are the intensity of solar radiation, air humidity, wind speed, air temperature, upper side temperature and lower side temperature of the solar cell. Meanwhile, the resulting output parameters are electric voltage and electric current. The results showed that the north direction without cooling produced a total output power of 666.59 W and an average efficiency of 13.54%, for those using the cooler produced a total output power of 737.71 W and an average efficiency of 14.16%. East direction produces a total output power of 454.81 W and an average efficiency of 11.51%, for those using the cooling system it produces a total output power of 542.25 W and an average efficiency of 13.90%. West direction produces a total output power of 340.33 W and an average efficiency of 13.22% for those using a cooling system resulting in a total output power of 550.72 W and an average efficiency of 13.29%. The highest performance of solar cells is obtained from solar cells that are placed towards the North using a cooler where the total output power is 737.71 W and an average efficiency of 14.16%, and for without a cooling system the total output power is 666.59 W and the average efficiency is 13.54%.

Abstract

Measuring electrical energy is an important matter between PLN and its customers. For this reason, PLN uses kWh meters as a tool to measure energy usage for customers. However, the kWh meter used must not only be able to measure, but must also be accurate, precise and easy. Especially for large customers, where special attention is needed for the use of electrical energy. For this reason, PLN has implemented electronic meters that have been installed with the AMR system for large customers. This is intended so that historical electricity usage for large customers can be recorded and monitored properly. Apart from that, the AMR system is also useful as an early detection of abnormalities in electronic meters for large customers by analyzing the data obtained. Through this data, DLPD (List of Subscriptions Needing Attention) can be determined so that customers who experience problems with their electronic meters can be monitored. With this DLPD feature, it really helps PLN employees in analyzing and evaluating the disturbances that occur. Keywords: Automatic Meter Reading, Electronic Meter, DLPD, AMICON
