Measurement and Investigation of the Incident Radiation in Case of Using Transparent Pyramidal Covers for Improving the Solar Panel’s Power Output
摘要: A new approach is presented to enhance the solar radiation intensity incident over the solar panel by using a transparent cover of pyramidal shapes. The pyramidal cover shape is manufactured of Polymethylmethacrylate dielectric material. The normal height of each pyramid is considered as a ratio of the base length. This ratio is considered in the present study to be 0.5, 1, and 1.5. The effect of the pyramidal covers on the solar panel voltage has been studied at different conditions. The experimental results confirm that the pyramidal cover shape causes the improvement to the solar panel output voltage by 4.2% when covering all the panel with pyramids of R=1 with a light incidence angle of 90 when the light rays come parallel to the panel surface. This improvement is found to decreases with covering fewer areas of the solar panel and with fewer incidence angles. It is found also that the distance between the light source and the panel is proportional to the output voltage improvement ratio compared to the panels output voltage without pyramidal cover. A mathematical model has been presented to prove the concept of increasing the electric and magnetic field of the incident radiation from the sun in case of presence of the transverse transparent barrier. Moreover, a mathematical ray tracking model was presented and validated with the experimental results by a maximum relative error of 14.8%

[IEEE 2017 International Renewable and Sustainable Energy Conference (IRSEC) - Tangier (2017.12.4-2017.12.7)] 2017 International Renewable and Sustainable Energy Conference (IRSEC) - Video Solar Plant Monitoring
摘要: In order to ensure efficient monitoring of solar plants, aerial video inspection using drones is unavoidable. The usually encountered problem is the shadow caused by drone on solar panels which may cause a false image interpretation. In this paper, we propose a technique of live shadow detection in video frames based on Otsu thresholding algorithm. To avoid Shaded Frames, the supervisor can automatically detect shaded captured frames of solar panels then acquire frames of the same area from another drone position with corrected angle of view of camera.

摘要: Electroluminescence (EL) imaging is used to analyze the characteristics of solar cells. This technique provides various details about solar panel modules such as solar cell characteristics, materials used, health status, defects, etc. The derived features from solar panel images provide a significant source of information for photovoltaic applications such as fault detection assessment. In this work, a method for classifying between the normal and a defective solar cell was implemented using EL imaging with selected digital image processing techniques through the Support Vector Machine (SVM) classifier. The EL images are processed using feature extraction procedures. The system was observed to provide an accuracy of 95%. The algorithm presented was implemented in MATLAB R2019b programming environment.

[IEEE 2019 Second Balkan Junior Conference on Lighting (Balkan Light Junior) - Plovdiv, Bulgaria (2019.9.19-2019.9.21)] 2019 Second Balkan Junior Conference on Lighting (Balkan Light Junior) - Influence of the angle of fall of light on the photovoltaic panel and its optimization - literature review
摘要: Scarce energy sources in today's world are the cause of meeting energy needs in everyday life through renewable energy sources. Concerns about climate change, rising oil prices and increased government subsidies lead to enlarged investments in renewable energy sources. Today, research focuses on optimizing and improving efficiency of these sources. Renewable energy is derived from natural processes that are constantly renewed. In most of its forms it is delivered directly from the sun or from the heat accumulated in the earth. The purpose of this publication is to present a realistic approach to enhancing efficiency in cases where green energy is extracted from sun through photovoltaic panels. This would lead to a higher power supply for artificial lighting. There are significant energy losses when installing a solar panel on a static structure in the morning and late afternoon due to the fact that the panel is not sun-oriented in east-west direction (daily sun motion). There are losses also when the solar panel is not perpendicular to sun rays (in north-south direction). This publication presents the influence of the sunlight angle falling on photovoltaics and its optimization.

Design of a Photovoltaic System with Ultracapacitor Energy Buffer
摘要: Global concerns over the damage caused to the environment by fossil fuels, as well as the instability of oil prices, has led to an increase interest in alternate electric power generation from renewable sources such as the sun, wind and geothermal energy. Solar energy is produced by solar panels which are made of materials having the capacity to create a flow of electric carriers when exposed to the solar irradiance. The efficiency of these panels depends on the sun light, and they cannot work at their maximum power point independently, hence, requiring Maximum Power Point Tracker (MPPT). This MPPT permits to compensate the changes in irradiance and temperature conditions and variations in load demands which cause power imbalances. As such, a photovoltaic system with supercapacitor energy buffer is designed using Psim software. The system consists of a photovoltaic array, a MPPT, a supercapacitor, and a charge controller which is to effectively balance and regulate power in the system.

[IEEE 2019 6th International Conference on Space Science and Communication (IconSpace) - Johor Bahru, Malaysia (2019.7.28-2019.7.30)] 2019 6th International Conference on Space Science and Communication (IconSpace) - Koch Fractal Loop Circular Polarization (CP) Antenna Integrated with Solar Cells
摘要: Minimal profile antennas for wireless devices which characteristics consisted of being low cost, highly reliable, and lightweight, it bears a new challenge for the design of the antenna in wireless communications. In this paper, we propose a design of circularly polarized microstrip patch antenna integration with solar cells for green wireless applications. Two techniques have been proposed to form the prototype between the communication system (design of antenna) and solar panel (solar cell). Both methods will face two issues generally; the solar system needs to get 100% sunlight and the magnetic field produced by radio communication systems as well as the electric field produced by solar cells should not affect the efficiency. The antenna is composed of a Koch fractal loop patch and the substrate is employed using a transparent material. This enables the light to pass through with high efficiency to illuminate the solar panel cells while the RF performance is maintained with minimal degradation. The communication frequency measures 2.6, 3.5 and 4.4 GHz. CST MWS simulation is also studied and compared among the different substrates which show different results based on the same parameters, which is implemented with a lattice of 2×2 square solar cells. With this arrangement, the solar cells will be able to obtain 100% of sunlight exposure. The characteristics of the broadband are achieved by combining resonances and the minimum axial ratio points created by the driven patch and solar cell surface.
