Abstract:
The changes in the intensity of solar radiation cause the electrical power produced by solar panels to be not optimal. The solar panel position control system to the position of the solar is an effort to overcome this problem. There are four Light Dependent Resistor (LDR) sensors placed on the sides of the four cardinal directions. The difference in the intensity of solar radiation received by each sensor causes the position of the solar panel to turn perpendicular to the position of the solar. The control method used is fuzzy logic control with three membership functions. The controlled variables are pitch angle and yaw angle in an active two-axis solar tracking system. Input fuzzy logic control is an error, and output is PWM. The results of the performance of the pitch angle control system produce settling time for 10 s and error steady-state obtained by 0.080 %, while for the yaw angle control system produces settling time for 13 s and steady-state error is obtained at 0.038 %. The existence of a control system resulted in an increase in the percentage of power above 30 % with a power difference of 7.49 W to a fixed panel.

Abstract:
Solar energy is one of the renewable energy that gets more attention from many countries. Solar photo voltaic (PV) takes the right position to get the maximum energy yield. The study was conducted by comparison of performance with two methods of tracking the sun with one axis and two axes by using ANFIS control (Adaptive Neuro-Fuzzy Inference System). The solar tracking system is a system that operates on the sun by using a light sensor and controls the photovoltaic to always perpendicular to the sun by changing the pitch and yaw axis of the sun tracing properties. LDR (Light Dependent Resistor) is one of the light sensors whose resistance changes depending on the intensity of incoming light. Direct current (DC )motor is used as a PV drive panel in a solar tracking system. A two-axis solar tracking system has a greater power output than a tracking system with a single photovoltaic panel that does not use a tracking system (fixed).

Abstract:
To investigate the optical performance of horizontal single-axis (HA) sun-tracked solar panels, a mathematical procedure to estimate daily collectible radiation on fixed, 2-axis and HA-tracked solar panels was developed based monthly horizontal radiation. Results showed that the annual solar gain on a HA-tracked solar panel was related to the orientation of HA, tracking the sun about the east-west axis was worst to boost the energy collection of solar panels, and tracking the sun about the south-north axis was best. Results also indicated that the ratio of annual collectible radiation on horizontal south-north sun-axis tracked solar panels to that with full 2-axis sun-tracking decreased with the increase in site latitude, implying that the horizontal south-north axis sun-tracking was suitable to be employed in regions with lower geographical latitude

Abstract:
Positioning a photovoltaic (PV) panel in the plane of maximum irradiation can increase the power output up to 57%. An automatic microcontroller based system for maximum power point tracking (MPPT) was designed and analyzed. The system was based on positioning the PV panel perpendicular to the solar irradiation. Photosensors were used to measure the difference of solar radiation intensity among three planes. The tracking system used an 8051 microcontroller to control a stepper motor which rotated the panel towards the plane with highest radiation intensity. The MPPT system was found to be 25.9% more effective in capturing solar power than a fixed panel with the same rating. This system would be useful to increase the power output of currently operating solar panels with minor modifications in mounting. Bangladesh J. Sci. Ind.

Abstract:
<p>Power output from a small solar panel can be affected by its power consumption when it consumes power from the solar panel. There has been a lack of proper research and experiment in the use of small solar panel with tracking systems. Its significance was detailed in this paper where the voltage output are compared with those which were externally powered. The solar trackers and a microcontroller have been designed and fabricated for this research. Due to the use of the tracking system (single axis and dual axis), the power consumption varies from one to another and its effect on the voltage output. Several experiments have been conducted and it was concluded that small solar panels are not efficient enough to utilize with tracking capabilities due to an increase in power consumption. The externally powered system was found to generate 18% more output compared to a selfsustaining system and that the increase in average power consumptions compared to a fixed panel were 31.7% and 82.5% for single-axis and dualaxis tracker respectively. A concrete evidence was made that utilizing solar tracking capabilities for low power rated solar panel is unfeasible.</p>

The sun tracking system that lets Parabolic Dish or PV panel orthogonal to the sun radiation during the day, can raise the concentrated sun radiation by up to 40%. The fixed Parabolic Dish cannot generally track the sun trajectory, also the single-axis tracking system can follow the sun in the horizontal direction (azimuth angle), while the two-axis tracker tracks the sun path in both azimuth and altitude angles. Dual axis automated control tracking system, which tracks the sun in two planes (azimuth and altitude) to move a Concentrated Parabolic Dish system to the direction of ray diffusion of sun radiation is studied and designed. The designed tracking system constructed of microcontroller or programmable logic control (PLC) with a digital program that operates sun tracker using driver, gear box to control the angular speed and mechanical torque, supports and mountings. Two steeper motors are modelled to guide the parabolic dish panel perpendicular to the sun's beam. In the present study, simulation scheme of two axis sun tracking system has been developed by operating under Matlab/Simulink. The program models and studies the effectiveness of overall system. The designed tracker has been studied with real data of sun trajectory angles (azimuth and altitude) as well as a Direct Normal Irradiation (DNI) to improve the effectiveness of parabolic dish panel by adding the tracking features to those systems according to the present site.©2019.

Abstract:
Recently, photovoltaic (PV) generation is becoming increasingly popular in industrial applications. As a renewable and alternative source of energy they feature superior characteristics such as being clean and silent along with less maintenance problems compared to other sources of the energy. In PV generation, employing a Maximum Power Point Tracking (MPPT) method is essential to obtain the maximum available solar energy. Among several proposed MPPT techniques, the Perturbation and Observation (P&O) and Model Predictive Control (MPC) methods are adopted in this work. The components of the MPPT control system which are P&O and MPC algorithms, PV module and high gain DC-DC boost converter are simulated in MATLAB Simulink. They are evaluated theoretically under rapidly and slowly changing of solar irradiation and temperature and their performance is shown by the simulation results, finally a comprehensive comparison is presented.

Abstract:
Mestrado em Engenharia Eletrónica e Telecomunicações
In the last few years we have witnessed the growth in the awareness relative to the effects of the climate change and global warming in the human life. The effects of extreme weather phenomenons are becoming more devastating. However we have also seen an increase in the consumer awareness relatively to the sources of the energy that they use. There is also an increase in the awareness from the power suppliers about the energy sources that they provide to their costumers. Nations that some years ago stood almost alone in defiance of the Kyoto protocol are now implementing programs that aim the reduction of carbon dioxide emissions to the atmosphere, namely the United States of America. With this objective, the investment in cleaner energy sources has increased considerably, both in research and in the creation of huge solar/eolian parks capable of producing large amounts of energy. However the prohibitive prices of the solar panels or of the solar trackers impedes the consumer of getting the return of the investment in a satisfactory time reducing the adherence to this kind of solutions. With this problem in our minds, the objective of this master dissertation is to aim for a reduction in the associated cost of the solar tracker solution by implementing new hardware and software capable of performing satisfactorily while being cheaper than the commercial solutions available. This aims to ally the bigger efficiency of the solar tracker solution (two axis) with a new control method free of proprietary solutions that do not increase value, only burden the consumer and thus halting the adoption of this kind of technology.
Nos últimos anos assistimos ao crescimento da preocupação relativa _as alterações climáticas e o seu impacto na vida humana. Assistimos cada vez mais a fenómenos climáticos extremos cujos efeitos são cada vez mais destrutivos e devastadores. No entanto existe uma maior consciencialização por parte dos consumidores sobre as fontes energéticas da energia que utilizam. Existe também uma maior consciencialização por parte das empresas energéticas sobre a origem das fontes energéticas que providenciam aos seus clientes. Assistimos ainda a nações que até há alguns anos se mostravam extremamente céticas acerca da influência humana nas alterações climáticas a criarem programas de redução das emissões de CO2 para a atmosfera, nomeadamente os Estados Unidos da América. Com este objectivo o investimento em energias limpas/renováveis aumentou consideravelmente, tanto na investigação como na criação de grandes parques solares e/ou éolicos. No entanto, o preço proibitivo dos painéis fotovoltaicos ou dos seguidores solares impede os consumidores de conseguirem um retorno do investimento num tempo aceitável, fazendo com que a adesão destes não seja tão grande como poderia ser possível e desejável. É com o objectivo de reduzir o custo associado aos paineis fotovoltaícos e a sua consequente democratização que esta dissertação de mestrado foi executada, aliando o maior rendimento dado pelo seguidores solares de dois eixos a um novo método de controlo livre de soluções proprietárias que não acrescentam valor e apenas oneram os consumidores.

The purpose of this thesis is to design an active solar panel dual-axis suntracking system with maximum power point tracking fuzzy controller. The tracking system tracks the maximum solar power point no matter what the environmental condition it is and orients the solar panel toward the Sun to enhance the efficiency of thephotovoltaic generation system. First, the operating points of the PV panel are adjusted by a boost converter. The PV voltage and current are measured in real time, and used to estimate the system parameters in the power-voltage polynomial equation and to identify the maximum power. Meanwhile, four light sensors sense one current respectively, which represent the illumination at the time. Inputting the maximum power and four currents to the two fuzzy controllers for dual-axis tracking system, the rotated angles will be got to make the mechanism rotate to the appropriate position. Through the sun tracking method, the PV panel will face the Sun directly at all time. Finally, the simulation results using Matlab verify the effectiveness of the proposed controller.

This study has developed two-axis solar tracking system with horizontally moving base, which can accommodate vehicle motion or avoid obstructing shadow and achieve better power generation efficiency. The system receives inputs from four photo resistor sensors to determine the general direction of the sun and drives two DC motors, one for azimuth angle and the other for elevation angle, to track the solar motion and keep the solar panel, which is setting on the tracking mechanism, facing toward the sun. Two micro-processors are used to control the system and transfer system data to a monitoring PC. The control law for both motors is a simple position control in sequential adjustments with azimuth angle first and elevation angle later. Presently, most solar panels made from crystalline silicon and used by general public do not require very high pointing accuracy to convert rated solar energy to electricity. The proposed design shall be a convenient and economical solution to easily gain more conversion from sun light to electricity for the same or similar type of solar panels. Also, the moving base provide one more degree of freedom to avoid blocking element in the sky or a test bed to exam the efficacy of the two-axis tracking system on large surface moving vehicles, such as ships or desert travelers. Experimental results are included to show the functions of the system, which indicate the proposed simple structure can achieve good tracking performance. Key words: two-axis solar tracking system, azimuth angle and elevation angle, moving base, micro-processors, crystalline silicon solar panels.

The traditional solar power system is installed by focus sun in fixed angle. It will not trace sun moving track. But, the output power of solar panel is affected by the angle and the strength of sun shine. And the traditional solar power system not always get the upright angle of input sun shine. So the absorbed energy is limited. To increase the power absorbed by solar panel as maximum, we need to use sun focus and tracking system to improve the power generation efficency. This paper is focusing on how to improving power generation efficiency by implementing 2-axises auto sun tracking system. The sun focus system mentioned in this paper is using image sensor device to detect the sun current location by projection method and using DSP to process the image get by image sensor and calculate the angle for motor to rotate to the right angle of X-axis and Y-axis. In this way, the solar panel will always focus the sun and thus achieve a real time sun focus system. Image sensor device is like human eyes to get the image of outside world and DSP is like the human brain to think and judge the information. So by using the DSP equipped with the Image sensor component, we can get the real time sun movement and location more precisely. And, by using projection method, we can prevent over exposure cause by sun light shining on the image sensor directly and the angle extension got is better, too. And, In this paper, by using the recycled material in our daily life. So this implementation is both good to environment protection and meet the goal of CO2 reduction and green design.

Environmental consciousness is on the rise in the world nowadays. Most of the buildings are closely related to the concept of energy-saving and environmental protection. Owing to Taiwan is surrounded by the sea with plenty of sunshine, hence it becomes a geographically strategy location for the development of solar energy recently. The trend is leading traditional industries toward new goals, i.e., environmental friendly and energy-saving and minimizing the impact of environmental degradation, so the next generation can enjoy a good quality of life. The aims of this research are to promote the use of solar photovoltaic (PV) under different environments and conditions. Besides that, it emphasizes on reduction environment pollution. In order to address the research gaps, the research constructs a 0.63kW floating solar PV system and subsequently investigates its practicality. Number of considerations is emphasized while designing the system. Among them are (1) the solar PV module is made from double-layered glass which aims to reduce the impact on the ecology, (2) the floating platform is designed in hull shapes, (3) the design is based on modular-based concept with quick and easy to assemble and disassemble. The floating platform consists of forward section (or fore) and the rear section (or aft) of a floating platform. The solar PV system does not use any petrochemical and hence carbon dioxide issue can be avoided. The use of solar photovoltaic is better than the diesel power generator as it achieves environmental protection, quiet and comfortable life, and can reduce the Earth's climate continues to deteriorate. The proposed PV floating platforms are made from zero pollution materials which can be recycled. Besides that, other advantages of floating platforms are quick to assemble, high structural stability, easy to install solar PV modules and etc. In order to prove the practicality and stability of the proposed solar PV system, real time power generation is collected by micro inverter which acts as a data acquisition system and subsequently the signal is transferred and stored in cloud storage system through WI-FI.

The performance and cost-effectiveness of photovoltaic cells depends greatly on the intensity of solar radiation to which they are exposed. Integrating a solar tracking system to the photovoltaic cell panel provides a way to improve the efficiencies of the solar energy system. Designing such an interdisciplinary system requires the mechatronic approach, through which the subsystems and their interfacings relating to the electrical, electronic, mechanical, structural, and control are integrated with multiple functionality and intelligent engineering realized in the microprocessor/controller operations and the controlled mechanisms. This chapter presents a case study of mechatronic system design and prototyping of a two-axis solar tracking system ST100 utilizing microcontroller OOPic.

Abstract:
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.

Abstract:
Abstract Solar trackers make solar panels perpendicular to solar ray to enhance solar power reaping. The relative motion between Sun and Earth has two degrees of freedom. Sun travels from east to west during daytime and also moves north and south due to Earth’s tilt. However, Sun’s daily north-south move is much smaller than its east-west move. Sensor-based solar trackers make solar panels perpendicular to solar ray based on sensor information. Although the existing sensor-based solar trackers increase solar power reaping from solar panels significantly, they also consume considerable power by driving solar trackers. Sensorless solar trackers make solar panels perpendicular to solar ray based on calculated solar location. The performance of sensorless solar trackers is not affected by bad weather. This paper is on sensorless solar trackers. Single-axis solar trackers have one degree of freedom solar tracking motion. They can catch Sun’s daily east-west movement effectively. The Sun’s small north-south movement can be covered for single-axis solar trackers by monthly or seasonal adjustment of their orientations. This research is focused on single-axis sensorless solar trackers that are driven by linear actuators. The advantages of linear actuator driven solar trackers are their self-locking function and high load carrying capacity. Their challenges include limited solar panel motion range, potential interference between an oscillating solar panel and its fixed supporting ground link, and high motor power consumption for solar tracking. The research of this paper is motivated by surmounting the challenges facing sensorless single-axis linear actuator driven solar trackers. In this research, linear actuator driven solar trackers will be designed and analyzed. The models of the designed solar trackers will be developed. The kinematic and dynamic performances of the modeled solar trackers will be analyzed and simulated. The results of this research will provide some guidelines for developing linear actuator driven solar trackers.

Abstract:
Solar trackers are rising in popularity; they benefit a wide range of applications since distributed solar energy generation can reduce electricity costs and support energy independence. In this paper, a simple solar tracking system is introduced. The system is a package unit that can be mounted on any solar panel. The system consists of an electrical motor connected directly to a sliding mass on a linear bearing. The electrical motor is controlled to slide the weight along the shafts in controlled steps. As a result, the photovoltaic panels are rotated automatically under the effect of controlled weight unbalance in fine angle increments to track solar trajectory without the need for traditional complex or costly mechanisms. Two light dependent resistors (LDR) sensors, mounted onto the surface of the solar photovoltaic panel, are exposed to solar irradiance and used to feed signals to a controller. A model of the solar tracking system is developed using ordinary differential equations, and numerically solved by MATLAB/Simulink™. The power consumption and tracking strategy of the proposed tracking system are estimated under realistic operating conditions (e.g. wind and brakes), and the power consumption is compared to the power generated by the photovoltaic panels. Optimum values for the sliding mass are suggested. Two photovoltaic modules are used to calculate the output parameters of the proposed tracking mechanism.

Abstract:
While solar photovoltaic (PV) panels have been used successfully to produce electricity for quite some time, it has been technically difficult to capture their heat because of the large area of a flat-plate photovoltaic panel. Likewise it has been difficult to manufacture solar concentrator systems that are of the same physical scale, about one square meter, as successful commercial flat-plate photovoltaic panels and incorporate them into a commercializable and easily manufactured solar energy system. This paper addresses the two problems by considering the feasibility of a single design of a one square meter plastic nonimaging solar concentrator that focuses sunlight on a heat-capturing, dense array of high-intensity photovoltaic chips. The individual one square meter modules are designed to be mounted on a 2-axis tracking system which could have a double polar-axis support for energy and cost efficiency. When coupled with an existing electronic control, these three components create a commercial-scale solar electricity device that also provides heat in quantities suitable for heating or cooling. Preliminary contacts with electric utilities and commercial/industrial businesses have found interest in procurement of the proposed technology for widespread harvesting and use of solar energy in the US and abroad.

Abstract:
The purpose of this paper is to examine the economic benefits of single-axis tracking photovoltaic (PV) power plants for a variety of locations with varying solar resources. Although the photovoltaic industry has been around for decades, the industry has changed dramatically in the past few years. A confluence of overproduction of panels and an economic recession have caused a precipitous drop in panel prices. Additionally, as tracking systems have matured, they have become more acceptable — technically and economically. With all these changes, it is not clear today if and where tracking is appropriate. This paper is to gauge the difference between a tracking and non-tracking configuration of a PV plant. For the purpose of this study, a net 20 MW alternating current (AC) PV plant was assumed to be developed at three different locations: California, Colorado, and New Jersey. The same panel of a moderate efficiency was picked and was used at each site. While a panel is not usually decided before development, a panel of typical characteristics was chosen so that prospective panels’ costs and efficiency could be assessed concerning tracking using a qualitative analysis. Levelized cost of energy (LCOE) of each site was determined using the Life-Cycle Cost Analysis methodology. For fixed mounting structures, the tilt of the panel was optimized based on the respective weather conditions to maximize production. After the tilt was decided, an economic sensitivity study taking shading and land prices into account was used to find the most economical spacing between mounting structures. For tracking, horizontal single axis tracking was assumed, and spacing was optimized as described above. The results of the study show that the benefit of tracking increases with the strength of the solar resource. In Newark, New Jersey, tracking raised the LCOE. In Daggett, California, tracking lowered the LCOE. In Boulder Colorado, the difference in LCOE was not appreciable. The study also showed that the most economical fixed PV power plant used less land on a capacity basis at each site. However, tracking plants, regardless of location or solar resources, produced more energy (kWh) per acre of land and could be described as more efficient on a land use basis.

Abstract:
The diversity of the energy matrix in the world is one of the challenges demanding fornew researches with alternative energy sources to bring exibility and sustainability in their use.According with this panorama, the generation of electric energy with solar photovoltaic systemsemerges as an important goal, and its technology is constantly advancing as an immediatesolution for this quest of diversity. This paper presents a predictive control for a solar trackingalgorithm to be used in single or double axis photovoltaic systems. The main characteristicand contribution of this algorithm represents a functional technological innovation because itdoes not use any sensors to determine the position of the Sun with respect to the panel. Suchalgorithm avoids unnecessary movements in cases of shadows on the panels caused by clouds,or some animal that could interfere on systems using the conventional sensors. The proposedsolar time algorithm was tested and compared with eld values, predicting the correct Sunposition with accuracy of less than 1o. The qualitative and quantitative results presented hereevidenced the real gain of the proposed algorithm-based system without any sensors to increasethe generation gain of photovoltaic power plants.

Abstract:
Now-a-days the field of applied mechanical systems opens new horizons for the use of orientation mechanisms. The opportunity to use mechanisms with a “sustainable purpose” leads to new approaches in the development of renewable energy systems design. The evaluation of the existing products shows that the tracking mechanisms for solar energy conversion systems may improve the efficiency of the solar energy conversion systems up to 30% to 50%. Applications of solar energy for domestic and industrial heating purposes have been becoming very popular. However the effectiveness of presently used fixed flat plate collectors, PV panels and parabolic collector are low due to the moving nature of the energy source. The presents research was carried out in the field of increasing the efficiency of the solar energy received by the solar collectors like PV panels, Flat plate collectors, Cylindrical Parabolic collectors using tracking systems by changing the position of the solar collectors correlated to the sun position for getting maximum radiation use of beam radiation falling on the solar collector. Two main aspects are taken into consideration, one optimizing the interaction between the mechatronic system components by integrating the analog electronic system by using a 555 timer in the mechanical model, and secondly by reducing the cost & time for the design process. The research work was carried out for location in chickballapur district at BGS R&D centre in Karnataka State, India. The results obtained in work is 24% increase in tracking efficiency of experimental model of flat plate collector, 30% increase in tracking efficiency in working model flat plate collector, 39 % increase in tracking efficiency of cylindrical parabolic collector and 36% increases in tracking efficiency of the Photovoltaic panel is found when compared to the non-tracking systems respectively. This paper presents the results of PV panel collector in detail for increasing the efficiency of the PV panel collector by tracking system with comparison of non-tracking system.
