The Difference

People can make solar energy alternative energy by employing solar panels to generate electricity. The utilization of solar energy on a solar panel to generate electricity is affected by the weather and the duration of the radiation, and they will affect the solar panel’s temperature. There are various types of solar panels that can be found on the market today, including Mono-Crystalline and Poly-Crystalline. The difference in the material used needs to be observed in terms of temperature changes in the solar module. Our study’s findings showed that a change in the temperature would impact the solar panel’s output voltage, and the solar panel’s output voltage would change when it was connected to the load although the measured temperatures were almost the same.

Selection of the most appropriate contractor for the installation of solar panels is essential to maximizing the benefit of this renewable, sustainable energy source. Solar energy is one of the 100% renewable energy sources, but implementation may not be very simple and cost-effective. A key phase in the implementation of renewable energy is the evaluation of contractors for the installation of solar panels, which is addressed as a multi-criteria decision-making (MCDM) problem. A new hybrid method is proposed that combines the stepwise weight analysis ratio assessment (SWARA) and full consistent method (FUCOM) weights that are represented as grey numbers used with traditional grey relational analysis (GRA) and evaluation based on distance from average solution (EDAS) methods. The ranking of contractors by both methods is the same, which confirmed the results presented in this research. The use of the grey SWARA-FUCOM weighting method combined with the GRA and EDAS methods increased the decision-makers’ (DMs) confidence in awarding the installation of the solar panel energy system to the top-ranked contractor.

The operation of fishing vessels skipjack pole and line contributes in catching tuna and skipjack fishes particularly in Indonesian waters. A previous study conducted by the authors found that there was no suitable method provided for the resistance computation atearly ship design phase. Besides, there was aninitial trim existed on the vessel during the operation which contributes for the resistance. The purpose of the study is to find the difference of resistance between the model test and the existing methods. The study was executed also to find the effect of initial trim of the vessel. The study began with collecting the database of a parent ship then to develop and transform into a model-scale for testing purpose in the towing tank. The results of model test were converted to the full-scale vessel. The resistance of full-scale vessel was computed based on the Holtrop and Guldhammer methods. The result of full-of resistance obtained from the model test and the methods were collected, evaluated and compared. The results showed the difference of the resistance for all methods. The result of model test is greater 21 % than that of Holtrop method at the service speed of 10 knots. Meanwhile, the result of model test is lower 14 % than that of Gulhammer method at the same speed. In addition, at the speed of 10 knots the initial trim of 0.5O increase 5 % ofthe resistance, the initial trim of 1O increase 10 % of resistance and the initial trim of 2O increase 16 % of resistance compared to the vesselwithout initial trim. In conclusion, the existing resistance methods are not suitable to be applied for skipjack pole and line fishing vessels. In addition, the initial trim contributes to increase the resistance and should be avoided during the vessel operation.

Abstract Solar photovoltaic technologies are worldwide renewable energy sources. However, the elevated temperature in solar panels is one explanation for reducing the performance of solar systems. An active air cooling system can be mounted on the back of the solar panel to avoid this phenomenon. In order to ensure that the solar system runs smoothly, monitoring needs to be done at each place where this solar energy system is located. The Internet of Things (IoT) is a network of linked, internet-accessible physical objects. It is the technology of the next generation that will soon be extended to society. The IoT refers to the system or ecosystem in which devices are connected to the Internet in real-time. Based on IoT, a smartphone can track the temperature of the solar panel anytime and anywhere. To overcome this problem, a Blynk IoT system monitors solar power status and controls the cooling air system. NodeMCU was the main microcontroller used in IoT systems. The IoT framework can be implemented easily and efficiently using NodeMCU. The experimental results of this project will monitor the performance of the solar panel and monitor it.

Tracking Device

This paper represents the comparison of the voltages generated by the tracking and static solar panels. The work also aims to design and  fabrication of a cheap and efficient tracking device. This device comprises of hardware and software. A rigid mechanical structure with nut and  screw as the transmission is developed. 4 LDRs and DC motors are employed, which are cheap and less power consuming. As far as the software  concerns, an open source microcontroller “Arduino UNO” board is used because of their simplicity and cost effectiveness. This Sun tracking device with a PV panel installed on it, is placed outside at the roof of the building along with a static solar panel. Output voltages generated from both panels are recorded in SD card through data logger in Arduino UNO. This real-time data shows the difference in amplitude of both the signals. Voltage of rotating panel is more than static one resulting that the tracking device can increase the efficiency of the panel by exposing the PV panel more to the sun light. Hence this setup proves that the solar panel with tracking system generates more energy than solar panel without tracking system. Keywords: Solar Tracker, LDR, PV Panel, Arduino UNO Board.

A real case study of an energy system based on a Solar Assisted Heat Pump (SAHP) fed by hybrid photovoltaic-thermal solar panels (PVT) and seasonal storage (SS) is presented in this paper. Exergy and exergy cost analyses are proposed as complementary methods for the assessment and better understanding of the efficiency of this cogeneration solar configuration. The system performance takes advantage of storage heat in summer, when the solar resource is high in Spain, and is then later consumed during the cold winter (heating season). The building is devoted to social housing, and it is currently under construction. The assessment is based on simulations developed using TRNSYS, a dynamic simulation software for energy systems. Results show that the unit exergy cost of the solar field is around 6. The cost of the seasonal storage is higher, about 13, and its formation is affected both by its own irreversibility and by the irreversibility of the PVT solar field. The cost of the heat delivered by the heat pump is around 15, being affected by all the upstream units and even by the grid. Besides, the analysis points out strategies for improving the system efficiency, such as increasing the size of the storage tank or improving the control strategy of the boiler.
