[IEEE 2018 9th International Conference on Mechanical and Aerospace Engineering (ICMAE) - Budapest (2018.7.10-2018.7.13)] 2018 9th International Conference on Mechanical and Aerospace Engineering (ICMAE) - Numerical Study of Wind Loads on A Solar Panel at Different Inclination Angles
摘要： A numerical analysis using Computational Fluid Dynamics methodology was carried out to study the effect of the different inclination angles on wind loads of solar panel. The wind flow is simulated as turbulent, incompressible flow with a free stream velocity of 10 m/s and a wind direction of 1800 and the inclination angles is chosen as 250, 300 and 350. The finite-volume-method is employed to solve the governing equations, coupled with the k─ε turbulence model with standard-wall treatment. The results indicate that pressure magnitudes on the panel were increased with the inclination angle. The maximum lift and drag force is appeared for the 350 inclination.

Drivers, barriers and enablers to end-of-life management of solar photovoltaic and battery energy storage systems: A systematic literature review
摘要： Distributed solar photovoltaic (PV) systems are a low-cost form of renewable energy technology that has had an exponential rate of uptake globally in the last decade. However, little attention has been paid to the potential environmental and human health related impacts associated with PV systems, if not managed properly at the end-of-life (EoL). Rare materials such as ruthenium, gallium, indium, and tellurium are essential components in PV panels, while battery energy storage systems (BESS) are composed of various chemistries (i.e. lithium-ion, lead acid, nickel cadmium, salt water, and flow batteries). An appropriate EoL management strategy for solar photovoltaic systems (i.e. PV modules, BESS) is necessary, not only to prevent and/or mitigate future environmental problems but also to reduce demand on rare earth materials. Drawn from a portfolio of 191 papers collected from Scopus and Web of Science databases between 2000 and 2018 (by 30 June 2018), a systematic quantitative literature review on solar energy systems EoL studies was conducted to examine the temporal trend of current research as well as methodological and geographical distributions of the published articles. Research has been concentrated within Europe, some parts of Asia, and North America, with experimental and modelling/simulation methods being mostly applied. The focus of this study was to compile and synthesise reported drivers, barriers, and enablers to EoL management of PV panels and BESS in the context of the circular economy. A conceptual framework is proposed to facilitate the transition of current PV system material flows and supply chain management practices to circular economy concepts. This paper also presents a future research agenda.

Low-concentration Optical Enhancement in Solar Panels
摘要： A simple, inexpensive approach aimed at cost reduction is through sunlight concentration enhancement with geometrical optics. Solar panels (~10-70 Wp range) were investigated with up to two mirror reflectors in order to determine gains in output in both dry and humid environments. Flat glass mirrors with 70% reflectance were used to direct sunlight to the solar panel surface create maximum of ~2.4 x sunlight enhancement. Averaged over different panels sizes operating in dry climate, gains in short-circuit current and peak power were 49.2 and 35.8% respectively; for the humid climate, respective gains were 29.7 and 23%. Continuous measurements as a function of time between 10:30 AM to 3 PM revealed respective current and power gains of 22.7 and 14.2%. Simple air cooling was determined to increase power output by 10%.

Design and compatibility analysis of a solar panel integrated UHF antenna for nanosatellite space mission
摘要： A compact UHF antenna has been presented in this paper for nanosatellite space mission. A square ground plane with slotted rectangular radiating element have been used. Coaxial probe feeding is used to excite. The rectangular slot of the radiating patch is responsible for resonating at lower UHF bands. One of the square faces of the nanosatellite structure works as the ground plane for the slotted radiating element. The fabricated prototype of the proposed antenna has achieved an impedance bandwidth (S11< -10dB) of 7.0 MHz (398 MHz–405 MHz) with small size of 97 mm× 90 mm radiating element. The overall ground plane size is 100 mm × 100 mm × 0.5 mm. The proposed antenna has achieved a gain of 1.18 dB with total efficiency of 62.5%. The proposed antenna addresses two design challenges of nanosatellite antenna, (a) assurance of the placement of solar panel beneath the radiating element; (b) providing about 50% open space for solar irradiance to pass onto the solar panel, enabling the solar panel to achieve up to 93.95% of power under of normal conditions.

A Climatology of Solar Irradiance and its Controls across the United States: Implications for Solar Panel Orientation
摘要： The National Solar Radiation Database (NSRDB), which is a spatially-dense modeled dataset intended to accurately represent long-term statistics, was used to construct a 15-year climatology of variations in the direct-beam and diffuse radiation fields across the United States (US). Continental scale variations in the radiation field vary predominantly by latitude during the winter and longitude during the summer. Eight sub-regions, defined by similar climate forcing and geography, demonstrate that the largest seasonal and year-to-year variations in the diffuse-to-direct ratio are in the Northwest and Southwest, while the smallest are in the Northeast and Southeast. The year-to-year variability across the western US is attributed to large scale climate signals, such as the El Ni?o Southern Oscillation (ENSO). A preponderance of diffuse radiation during the summer in the Midwest, South-Central, Southeast and Northeast is demonstrated. It is suggested that harvesting procedures be tuned to accommodate this preponderance. Orienting a fraction of fixed panels to optimize the diffuse beam during the summer in these regions is suggested to increase energy yield. Adopting a seasonal and year-to-year approach in the harvesting procedure in the Northwest and Southwest that is tuned to large scale climate signals is likely to optimize harvest yield in those regions.

AIP Conference Proceedings [Author(s) INTERNATIONAL CONFERENCE ON SUSTAINABLE ENGINEERING AND TECHNOLOGY (ICONSET 2018) - Karnataka, India (19–20 April 2018)] - Design and development of solar panel tracking mechanism
摘要： The solar power is quickly gaining significance since an energy reserve as fossil oil costs vary. With ordinary fixed solar panel we can’t get maximum utilization of sun radiation that is why we are using a single axis solar tracking system which will continuously track the sun radiation, so that the angle of incident of solar radiation with the solar panel should always perpendicular to get maximum efficiency of solar incident radiation. The daylight dependent resistors carry out the work of sensing the vary in the location of the sun, that is dealing with the particular modify in the solar plate location by switching on and off the motor. The direct circuit does the work of supply the input from the sensor also gives demand towards the motor to run during order to attempt the modify in the sun’s position. It has been found that the solar tracking system can gather about 17.72% extra power than fixed panel structure and thus more effectiveness are achieved through this mechanism.

[IEEE 2018 International Seminar on Application for Technology of Information and Communication (iSemantic) - Semarang, Indonesia (2018.9.21-2018.9.22)] 2018 International Seminar on Application for Technology of Information and Communication - Comparison of First Order Differential Algorithm, Perturb and Observe (P&O) and Newton Raphson Methods for PV Application in DC Microgrid Isolated System
摘要： The necessary for energy always increases every year, so it is necessary energy alternative to overcome the phenomenon. From some alternative energy that is currently widely developed is solar energy. Unfortunately the use of solar energy with the help of solar panels produces power that varies according to the irradiation received and the temperature on the solar panel. Irradiation is the emission of energy coming from the sun. This parameter causes the output power characteristic curve to be non-linear. And the power generated by PV has not reached the maximum power point. To overcome this problem requires an arrangement to find the maximum power point and make it stable at that point. Therefore, this paper proposes "Comparison of First Order Differential Algorithms, Perturb and Observe(P&O) and Newton Raphson Methods for PV Application in DC Microgrid Isolated System" so that the maximum power point can be achieved quickly and accurately. In this paper we tried to compare 3 methods of First-order Differential, P & O (Perturb and Observe) and Newton Raphson by using ZETA Converter as its object in switching settings. By using the simulation can be obtained the results of tracking speed and maximum power level. The results of the simulation show that error power the First-order Differential is 4%, P & O is 0.26389% and Newton Raphson is 0.45178%. It is evident that Raphson's newton algorithm is superior to speed and accuracy.
