Renewable energy is the path for a sustainable future. The development in this field is progressing rapidly and solar energy is at the heart of this development. The performance and efficiency limitations are the main obstacles preventing solar energy from fulfilling its potential. This research intends to improve the performance of solar panels by identifying and optimizing the affecting factors. For this purpose, a mechanical system was developed to hold and control the tilt and orientation of the photovoltaic panel. A data acquisition system and electrical system were built to measure and store performance data of the photovoltaic panels. A design of experiments and Response Surface Methodology were used to investigate the impact of these factors on the yield response as well as the output optimization. The findings of the experiment showed an optimum result with a tilt of 60° from the horizon, an azimuth angel of 45° from the south, and a clean panel condition. The wind factor showed insignificant impact within the specified range.

Indonesia has more than 17,000 islands and has plenty of beautiful beaches and underwater spots which have great potential for maritime tourism. Tourism was ranked 3rd on Indonesia's foreign income and plays an important role for the country’s ecomony. Despite having potential advantages, the government has not yet maximized its efforts to develop the attractiveness of its maritime tourism. Beside the beautiful spots Indonesia is also blessed with all year long sun shine, which could be tapped as renewable and green energy as substitution to fossil fuel. Refer to these great advantages of natural resources the research was aimed to support the government’s program in developing its maritime tourism and to promote the use of green and renewable energy by designing a solar-powered tourism recreational boat which has 12 meters of length. The paper is focused on the design of solar energy and its electrical system, which includes conversion of solar energy to electrical energy and store it in the battery, the required electrical power is also predicted based on the appliances and equipment installed in the boat, the optimum attachment of solar panels on the boat structure is also calculated. All the methods and information we use are obtained from literature study, discussion with experts, and surveys to Jagur as solar-powered electric boat from Universitas Indonesia.

Global warming and climate change coincide in their main causes, the massive emission of greenhouse gases, which retain heat in the atmosphere and on the earth's surface through the so-called greenhouse effect. The generation of electricity by means of fossil fuels is an important emitter of greenhouse gases (CO2, CH4, N2O), and halogenated compounds containing F, Cl, and Br. With the purpose of contributing to the construction of viable solutions to the current energy situation of the country and in the foundation of a sustainable future, the use of solar energy for the generation of electricity by means of solar panels represents an option. The purpose of this study is to describe and control the solar cell protection material Ethylene-Vinyl-Acetate (EVA), as a contribution to the Quality Assurance of solar panels, since the function of this material is essential for the protection of solar cells, which are a vital part of the solar panel. The tests performed were: Gel content, adhesion test, and durability tests. The results obtained were within specification according to IEC 61215. From this work it is concluded that it is important to continue testing the whole process and components of the solar panels in order to guarantee the useful life of the finished product, as well as to contribute to sustainable development.

Research into the process of photosynthesis could benefit a range of areas - from increasing output from agriculture and developing stress resistant crops, to the design of solar panels and solar energy harvesting technology. In order to develop our understanding of this process, the study of photosynthesis needs to focus on the chloroplast - the cellular compartments where photosynthesis takes place. Professor Mitsumasa Hanaoka, from the Laboratory of Molecular and Cellular Functions in the Department of Applied Biological Chemistry, Graduate School of Horticulture at Chiba University, is exploring how plants coordinate messages between the nucleus and chloroplasts responsible for optimised photosynthesis.

All day long the transportation infrastructure receives solar energy from the sun rays, storing much of them as heat that is left to dissipate by nightfall. The concept of harvesting solar energy from transportation infrastructure is enticing because it offers a way to collect solar energy by utilizing an extensive infrastructure that already exists. Thus, an attempt was made to investigate novel methods for solar energy harvesting and conversion with potential economic efficiency substantially beyond that of current technology. Particularly, a comparative study was conducted between rigid and flexible solar panels.

AbstractThe most recent and promising trends in development of renewable sources of energy are Combined Heat and Power (CHP) systems. The newest solutions from this field are hybrid compact solar panels. The correct operation of both systems, i.e. the photovoltaic panel and the heat exchanger requires an effective connection between the two. The adhesives utilized to interconnect above elements should provide a stable and hermetic joint able to withstand mechanical and thermal impacts of the surrounding environment factors. The paper presents the research results over the impact of the type and the amount of reinforcing phase on the physical and mechanical properties of epoxy resin matrix composites reinforced with particles of non-ferrous metals (Ag, Cu, W, Al), dedicated as adhesives for connections between photovoltaic panels and heat exchangers. Based on the experimental findings the usefulness of classical analytic models for valuation of polymer-metal composites properties was validated.

Solar energy usage is thriving day by day. These solar panels are installed to absorb solar energy and produce electrical energy. As a result, the efficiency of solar panels depends on different environmental factors, namely, air temperature, dust (aerosols and accumulated dust), and solar incidence, and photovoltaic panel angles. The effects of real conditions factors on power and efficiency of photovoltaic panels are studied in this paper through testing the panel in real environmental tests. To study the mentioned parameters precisely, two panels with different angles are used. The case study is regarding a region of Tehran, Iran, in summer and winter seasons. The results show that panel efficiency during winter is higher than summer due to air temperature decrement. It is discovered that among air pollutants, Al and Fe have the most share in polluting the air that affect the photovoltaic efficiency. Moreover, measuring the accumulated dust on the panels shows more amount in winter in comparison with summer. The important point in studying the effect of tilt angle is that inconformity between solar incidence and photovoltaic panel angles would result in solar radiation absorption and eventually panel efficiency loss and also, photovoltaic panel installation angle would affect the amount of dust deposited on its surface.

Solar trackers orient solar panels toward the Sun to increase solar energy harvesting. To enhance solar energy capture, solar trackers change solar panels’ orientation throughout the day to follow the Sun’s path and make solar panels normal to the solar ray. The current solar trackers make solar panels perpendicular to the solar ray because of the active motion control of the solar panels. However, they also consume considerable power since the motion of solar panels is usually generated by two motors simultaneously and continuously. The merits of the existing sensor-based dual-axis solar trackers are compromised by their motor power consumption. In this research, the Sun’s location relative to an arbitrary point on Earth is determined at any time on any day in any year. Because of the determined solar location and path, only one axis is needed for the proposed solar tracker since it does not rely on any sensor to determine the Sun’s location. The current single-axis solar trackers face challenges on the limited oscillation range of the solar panels and the potential interference between an oscillating solar panel and its corresponding ground. In this paper, a sensor-free single-axis solar tracking linkage is designed to surmount these challenges. The solar tracking motion of the designed linkage is simulated. The designed linkage is fabricated and tested. The motion of the fabricated linkage is controlled by a microcontroller to generate the desired intermittent solar tracking motion.
