Abstract

This study aims to evaluate the impact of capacitor bank capacity on energy efficiency and power factor at Aston Inn Hotel Tasikmalaya. The hotel's electrical system is characterized by a predominance of inductive loads, which generate a considerable amount of reactive power, thereby decreasing the overall power factor. To address this issue, capacitor banks are commonly used as a power factor correction tool, helping to reduce reactive power, minimize energy losses, and lower operational costs. However, the correct sizing of capacitor banks is crucial, as incorrect capacities can lead to system inefficiencies and potential instability. In systems where the power factor is low, there is an increase in electrical current, which contributes to higher energy losses in the form of heat and, consequently, elevated operational expenses. This study adopts a comprehensive approach involving direct measurement of the hotel's electrical system, detailed analysis of load data, and calculation of the ideal capacitor bank capacity required for optimal performance. The aim is not only to improve energy efficiency but also to enhance the overall stability and safety of the hotel's electrical network. The results of this research reveal that the currently installed capacitor bank has a capacity of 300 kVAr, which is significantly larger than the ideal requirement of 55 kVAr as determined through load analysis. This substantial excess in capacity results in a power factor shift from lagging to leading. Such a shift can lead to adverse effects on the electrical system, including potential instability, equipment malfunction, and increased wear and tear on system components. Additionally, it was discovered that the existing Power Factor Controller (PFC) is not operating at its optimal setting, further complicating the situation and preventing the system from achieving the desired power factor improvements. Based on these findings, it is recommended that adjustments be made to the capacitor bank capacity to align with the calculated ideal value. Moreover, a reconfiguration and proper tuning of the Power Factor Controller are necessary to ensure optimal performance. These corrective actions are expected to enhance power factor correction, improve energy efficiency, reduce operational costs, and maintain system stability within the hotel's electrical network.

Abstract

The utilization of solar energy through photovoltaic (PV) technology continues to evolve as a promising renewable energy source. However, the efficiency of solar panels remains limited by heat generated during operation, causing performance degradation as temperature rises. This phenomenon presents a major challenge in optimizing PV technology. This research aims to enhance the efficiency of photovoltaic systems by incorporating Thermoelectric Generator (TEG) modules, resulting in an innovative hybrid Photovoltaic-Thermoelectric Generator (PV-TEG) system. The PV-TEG hybrid system is designed to harness excess heat produced by solar panels, which is then converted into additional electrical energy through TEG modules, utilizing the Seebeck effect. In this experimental study, two heat transfer methods were tested and compared: Micro-Channel Heat Pipe (MCHP) and copper plate. Both methods were evaluated to enhance the temperature gradient across the TEG modules, with the goal of optimizing the hybrid system's performance. The research methodology included design, fabrication, and testing of PV-TEG hybrid system prototypes under various controlled environmental conditions. Measured parameters included operational temperature, output voltage, current, and total power generated. Thermodynamic and electrical analyses were conducted to evaluate energy conversion efficiency and overall system performance. Test results showed that the PV-TEG hybrid system could increase overall efficiency by up to 10% compared to conventional solar panels. The use of copper plates as heat transfer media resulted in higher efficiency compared to MCHP, indicating greater potential for practical implementation. Economic analysis also demonstrated the long-term feasibility of this hybrid system, despite higher initial costs.In conclusion, the developed PV-TEG hybrid system makes a significant contribution to improving the energy efficiency of solar panels.

Abstract

The need for electrical energy in Indonesia is increasing, while dependence on fossil fuels remains dominant. One potential alternative is the utilization of solar energy through rooftop Solar Power Plants (PLTS). This study aims to design a rooftop PLTS system in the Integrated Classroom and Laboratory Building, Campus 1, Siliwangi University with a technical and economic approach. The research method includes collecting data on load profiles and potential solar radiation, designing system capacity, selecting main components, and simulating using PVsyst software to obtain estimates of energy production and system performance. The planning results show a design capacity of 71,107 Wp with a configuration of 118 solar panels with a capacity of 600 Wp, which produces energy production of around 299–318 kWh per day or equivalent to 109–116 MWh per year. The PVsyst simulation produces an average Performance Ratio value of around 80%, which is in the good category. However, the economic analysis using the Net Present Value (NPV) method shows a negative value (−996,310,000), so this project is not yet financially feasible if implemented in a fully off-grid scenario. In conclusion, the implementation of rooftop solar power plants in the Integrated Classroom and Laboratory Building, Campus 1, Siliwangi University is technically feasible, but not yet financially feasible under current conditions. Therefore, it is recommended to implement a hybrid or on-grid scenario, as well as an electricity tariff sensitivity analysis to increase economic feasibility.
