Solar Tracking

Nowadays, renewable energy such as solar power has become important for electricity generation, and solar power systems have been installed in homes. Furthermore, solar tracking systems are being continuously improved by researchers around the world, who focus on achieving the best design and thus maximizing the efficiency of the solar power system. In this project, a fuzzy logic controller has been integrated and implemented in a medium-scale solar tracking system to achieve the best real-time orientation of a solar PV panel toward the sun. This project utilized dual-axis solar tracking with a fuzzy logic intelligent method. The hardware system consists of an Arduino UNO microcontroller as the main controller and Light Dependent Resistor (LDR) sensors for sensing the maximum incident intensity of solar irradiance. Initially, two power window motors (one for the horizontal axis and the other for the vertical axis) coordinate and alternately rotate to scan the position of the sun. Since the sun changes its position all the time, the LDR sensors detect its position at five-minute intervals through the level of incident solar irradiance intensity measured by them. The fuzzy logic controller helps the microcontroller to give the best inference concerning the direction to which the solar PV panel should rotate and the position in which it should stay. In conclusion, the solar tracking system delivers high efficiency of output power with a low power intake while it operates.

Panel Surface

Solar Photovoltaic (PV) energy conversion has gained much attention nowadays. The output power of PV panel depends on the condition under which the panel is working, such as solar radiation, ambient temperature, dust, wind speed and humidity. The amount of falling sunlight on the panel surface (i.e., solar radiation) directly affects its output power. In order to maximize the amount of falling sunlight on the panel surface, a solar tracking PV panel system is introduced. This paper describes the design, development and fabrication of the solar PV panel tracking system. The designed solar tracking system is able to track the position of the sun throughout the day, which allows more sunlight falling on the panel surface. The experimental results show that there was an enhancement of up to a 64.72% in the output power of the PV panel with reference to the fixed orientation PV panel. Further, this study also demonstrates that the full load torque of the tracking system would be much higher than the obtained torque, which is required to track the position of the sun. This propounds, that the proposed tracking system can also be used for a higher capacity PV power generation system.

Solar Tracking

The energy extracted from photovoltaic (PV) or solar thermal depends on solar insolation. For the extraction of maximum energy from the sun, the plane of the solar collector should always be normal to the incident radiation. Sun trackers move the solar collector to follow the sun trajectories and keep the orientation of the solar collector at an optimal tilt angle. Energy efficiency of solar PV or solar thermal can be substantially improved using solar tracking system. In this paper, an automatic solar tracking system has been designed and developed using DC motor on a mechanical structure with gear arrangement. The movements of two-axis solar trackers for the elevation and azimuth angles are programmed according to the mathematical calculation by using the Borland C++ Builder. Performance of the proposed system over the important parameter like solar radiation received on the collector, maximum hourly electrical power has been evaluated and compared with those for fixed tilt angle solar collector.

Nowadays, renewable energy is being used increasingly because of the global warming and destruction of the environment. Therefore, the studies are concentrating on gain of maximum power from this energy such as the solar energy. A sun tracker is device which rotates a photovoltaic (PV) panel to the sun to get the maximum power. Disturbances which are originated by passing the clouds are one of great challenges in design of the controller in addition to the losses power due to energy consumption in the motors and lifetime limitation of the sun tracker. In this paper, the neuro-fuzzy controller has been designed and implemented using Field Programmable Gate Array (FPGA) board for dual axis sun tracker based on optical sensors to orient the PV panel by two linear actuators. The experimental results reveal that proposed controller is more robust than fuzzy logic controller and proportional-integral (PI) controller since it has been trained offline using Matlab tool box to overcome those disturbances. The proposed controller can track the sun trajectory effectively, where the experimental results reveal that dual axis sun tracker power can collect 50.6% more daily power than fixed angle panel. Whilst one axis sun tracker power can collect 39.4 % more daily power than fixed angle panel. Hence, dual axis sun tracker can collect 8 % more daily power than one axis sun tracker.

<em>Nowadays solar panel is widely used as an independent power plant, it can be seen the many applications of solar panels on electrical equipment, such as traffic light, general lighting, etc. The energi produced by solar panel is affected by the absorbed sunlight. generally solar panels are implemented statically, this causes the absorption of solar energi is not maximal in the morning and afternoon. To maximize the absorption of sunlight, solar panels must always be facing perpendicular to the position of the sun. Automatic solar tracking system is needed to solve these problems, It is makes solar panels always perpendicular to the sun and can follow the movement of the sun, so that the absorption of solar energi is more leverage. The results of the test show the use of automatic tracking system to get the maximum absorption of solar energi indicated by a more stable voltage output,and the power generated is greater than using a static solar panel. Automatic Sun Tracking System (ASTS) increase the average power up to ± 39-41 watt / day with the efficiency of ASTS 81.66% on PV panel 50 WP.</em>

This work focuses on the performance evaluation of a Standalone Solar Photovoltaic (PV) system for electricity generation in an estate requiring a daily power consumption of 50KW. This was achieved through a solar tracker software/hardware – embedded programme control system. A programmable microcontroller (PIC16F877A), light detection sensors (CDS NORP 12), motor driver IC (L293D), power relays (NTE-R22-5) and a dc gear motor with linear actuator (HARL-3618) were used. MikroC Pro compiler from Mikro Electroniker was used to programme the PIC16F877A. A fixed PV panel of same size was placed side by side and tested with the solar tracking system. The test results obtained showed that the solar tracking system produced 14.3W at 8:00am, increases to a maximum of 25.83W at 1:00pm and decreased to 16.28W at 6:00pm while the fixed PV panel produced 5W at 8:00am, increased to a maximum of 25.62W at 1:00pm and decreased to 10.6W at 6:00pm. These results gave the solar tracking system an efficiency increase of 33 percent over the fixed system. The designed system installed in residential homes has capacity to guarantee sustainable, durable and improved power supply.
