Solar energy is one source of energy and has advantages compared with fossil energy sources. Solar energy is very necessary to be researched and developed further, including at the University of Muhammadiyah Sidoarjo. Utilization of solar energy, it is by preparing the installation of Photovoltaic Cell (solar cells) to determine the placement position and angle of the slope. The utilization of solar power will be applied at the Laboratory of Electrical Engineering University of Muhammadiyah Sidoarjo to make Solar Building System (SBS). This study will carry out an analysis of the utilization of solar energy compared to using the resources of PT. State Electricity Company (PT. PLN). The analysis was done with the installation of SBS consider investment and installation costs grid drawn on the Net Present Value, and compare the operating cost between SBS with the grid system. This research show the results of the analysis in gain by using SBS will have a value higher efficiency compared to the grid system at a certain time span by considering Break Event Point (BEP) SBS installation investment. Over 21 Years.

Solar Panel Remote Monitoring and Control System on Miniature Weather Stations Based on Web Server and ESP32 The weather station helps in planning socioeconomic activities such as agriculture, tourism, transportation, marine activities and plantations. The station needs an energy source, an electric energy source to operate, and is needed to get continuous assistance. This study aims to build a system for using two sources of electrical energy to support electricity stations that can be monitored and control remotely and provide information on the use of electrical energy in miniature weather stations into a web server. This research produces a remote monitoring and control system that can automatically switch primary energy sources to backup energy sources. When taking the main current source goes out, the system is able to carry the energy source back to the main source back to the main source alive again. The system can make changes manually using a web server that can be controlled remotely. When the battery reaches a voltage above 14.40 volts, the charging process stops and the system uses electrical energy from the battery. When the battery voltage reads 11.89 volts, do the battery charging process again. Electrical energy system information on miniature stations can display information about voltage, current, power, temperature and intensity of sunlight in the form of graphical visualization in real time.

“…Some studies suggested a horizontal arrangement of the reflector with the solar panel [23]. A model of ray tracing to calculate the irradiation rise was proposed [24]. Some used diffuse reflectors, which are a collective view factor and specular reflectance mode [25], whereas others use a 2-D specular reflectance model and experimental data [26].…”

Design of a Building-Integrated Photovoltaic System with a Novel Bi-Reflector PV System (BRPVS) and Optimal Control Mechanism: An Experimental Study

et al. 2018

Environment protection and energy saving are the most attractive trends in zero-carbon buildings. The most promising and environmentally friendly technique is building integrated photovoltaics (BIPV), which can also replace conventional buildings based on non-renewable energy. Despite the recent advances in technology, the cost of BIPV systems is still very high. Hence, reducing the cost is a major challenge. This paper examines and validates the effectiveness of low-cost aluminum (Al) foil as a reflector. The design and the performance of planer-reflector for BIPV systems are analyzed in detail. A Bi-reflector solar PV system (BRPVS) with thin film Al-foil reflector and an LLC converter for a BIPV system is proposed and experimented with a 400-W prototype. A cadmium-sulfide (CdS) photo-resistor sensor and an Arduino-based algorithm was developed to control the working of the reflectors. Furthermore, the effect of Al-foil reflectors on the temperature of PV module has been examined. The developed LLC converter confirmed stable output voltage despite large variation in input voltage proving its effectiveness for the proposed BRPVS. The experimental results of the proposed BRPVS with an Al-reflector of the same size as that of the solar PV module offered an enhancement of 28.47% in the output power.Electronics 2018, 7, 119 2 of 22 the long-term cost of the building sector. Compared to a standalone PV system, BIPV does not require any extra land for installation and the cost can be balanced by installing this on the rooftop of the building structure [3]. However, the lower efficiency and higher initial cost make BIPV less practical and difficult to commercialize. Dye-Sensitized Solar Cells (DSSCs) have attracted considerable attention in recent years because of their simple assembly, lightweight, flexibility, economical price of materials, satisfactory photocurrent transformation efficiency, precise energy return time, and tunable optical properties [4]. On the other hand, DSSCs have power conversion efficiency of more than 14% with a limited active area; the output power decreases with increasing cell effective area of the photoanode [5]. An alternate solution exists to increase the net output power from the PV module to reduce the cost of the system because the initial cost of the PV system is the main hurdle to the widespread use of this technology. The output power can be increased by increasing the incident light on the PV system [6]. The position of the Sun is not fixed to one place because it changes its position from dawn to dusk and also during the entire year, which means that a fixed PV system is inefficient. Therefore, the tracking of single-and dual-axis PV systems are suggested for this purpose [7,8]. On the other hand, such a system has two disadvantages, increase in initial cost and decreased lifetime of the mechanical parts of the PV system. Moreover, such a system also requires extra power supply and motors to move the solar system, which makes the system more complex and increases the size of the ...
