This paper presents a smart dual-axis solar tracking system, its architecture includes sensors, embedded controllers, AC motors, Integrated electric putter design biaxial institutions, and the GSM automatic report of fault notification, to achieve autonomous tracking solar track system and adjust the solar panels to reach the maximum smooth by tracking the solar azimuth angle and elevation angle, and ensure that the solar panels with the sun to maintain the vertical in any time and any place, thus achieving the best power efficiency. This system proposed a dual-axis design, and an embedded controller used as the main system controller to detect voltage difference and determine the solar azimuth angle with four groups of CDS as a sensing element. To lock the sun, the solar panels be perpendicular via the moving of AC motor (EW) and motorized faders (north-south). The control system software using C language can be extremely fast and accurate tracking of the solar angle, and dual-axis operation with recovery mode to save the power loss. Finally, we have the actual analysis and verification of benefit of power generation in this paper, from this experimental results, we can verify the integration of build dual-axis solar tracking system and solar power system have promoted 30% generating power capacity more than fixed solar power system and has low failure rate. It can improve the problem of traditional tracking system reliability and greatly enhance the usefulness of this system.

The capability of photovoltaic (PV) panel to generate energy approximately follows the intensity of the sunlight on the panel. A dual-axis solar programmable logical controller (PLC) based automatic tracking system and its supervisory and control system was designed and implemented in this paper. The proposed automatic tracking system controls elevation and orientation angles of solar panels such that the panels always maintain perpendicular to the sunlight. The measured variables of our automatic solar tracking system were compared with those of a fixed-angle PV system. The results indicated that the automatic solar tracking system is low-cost, reliable and efficient. As a result of the experiment, the electricity generated by the proposed tracking system has an overall increase of about 8%similar to 25% more than the fix-angle PV system.

The main goal of increasing the efficiency is to get the maximum power from the solar panel. The project is to design and implementation simple and cheap price solar tracker system with two axes (azimuth angle as well as altitude angle) using Light Dependent Resistor (LDR) with real dimensions the project composed of solar panel, two-motor satellite dish and ball-joint, LDR sensor module and an electronic circuit. This project is compared with fixed solar panel and the results showed that solar tracker more output power than fixed solar panel. The project is divided into two parts;hardware and electronic. Hardware part generally composed of solar panel, two-DC motors with gearbox and LDR sensor module. Second part is electronic circuit. In this work sensing of the sun position carried out in two stages, first stage or direct sensing performed via set of LDR sensors as output tuning to trims the azimuth and altitude angles. second stage, when the weather is cloudy, dusty or rain, the tracking system will stop so the system stay in the position of the sun without move but according to Kelly cosine relation the power will decrease according to Iraq - Baghdad city weather because we have about 10-15 rainy days that every day have (2-4) hours have cloudy and rain. The energy extracted from photovoltaic (PV) or any solar collector depends on solar irradiance. For maximum extraction of energy from the sun, the solar collector panel should always be normal to the incident radiation solar trackers moves the solar collector to follow the sun path and keeps the orientation of the solar collector at an optimal tilt angle. solar tracking system improves substantially the energy efficiency of photovoltaic (PV) panel. In this paper, an automatic dual axis solar tracking system is designed and developed using Light Dependent Resistor (LDR) and DC motors on a mechanical structure with gear arrangement.

The main goal of this project is to design a very precise solar tracker. The project is divided into two parts;hardware and software. Hardware part generally composed of solar panel, two-DC motors with gearbox, LDR sensor module and electronic circuit. Software part represents the thinking behavior of the system, that is how the system acting under several weather conditions. In this work sensing of the sun position carried out in two stages primary and secondary. Primary stage or indirect sensing performed via sun-earth relationship as a coarse adjustment and second stage or direct sensing performed via set of LDR sensors as output tuning to trims the azimuth and altitude angles. If the weather is cloudy or dusty, the tracking system uses primary stage or sun-earth geometrical relationships only to identify the location of the sun;so the system tracks the position of the sun regardless the weather condition. The energy extracted from photovoltaic (PV) or any solar collector depends on solar irradiance. For maximum extraction of energy from the sun, the solar collector panel should always be normal to the incident radiation solar trackers moves the solar collector to follow the sun path and keeps the orientation of the solar collector at an optimal tilt angle. solar tracking system improves substantially the energy efficiency of photovoltaic (PV) panel. In this paper, an automatic dual axis solar tracking system is designed and developed using Light Dependent Resistor (LDR) and DC motors on a mechanical structure with gear arrangement. Two-axis solar tracking (azimuth angle as well as altitude angle) is implemented through Arduino UNO controller based on Sun-Earth Geometry. The results indicated that the automatic solar tracking system is more reliable and efficient than fixed one.

The use of solar energy has become more prevalent as years passed by. Nowadays, installations of photovoltaic modules are done in residential households to help the consumers to save energy and cut expenses. This study aims to design a smart net metering controller for a dual axis photovoltaic system with energy management capabilities. Using a smart controller which is responsible for the dual-axis solar tracking system that rotates from the x and y axis through detection of light using four light dependent resistors (LDR) to locate the position where the sunlight is more extensive for greater solar power generation. It is also responsible for the energy management system which displays the voltage, current and power on a graphical user interface (GUI) and the data that was measured is transferred wirelessly through a Bluetooth device.

The main aim of the present work is to enhance the efficiency of a PV operated solar pump by effective design of VFD and tracking system;To achieve this, various components inside a Variable Frequency Drive (VFD) are studied and analyzed, thereby performing few modifications like changing normal DC bus conductor into a foiled conductor, regulating output voltage coming from VFD by using voltage regulator, made sure VFD is placed very close to motor to reduce the conductor length and increasing the grade of cables;for solar PV panels, instead of static structures holding the panels, we used automatic tacking structures. A prototype of 2 kWp grid-interactive SPV system integrated with 1.5 HP single phase pump was installed at Tribi systems Private Limited, Bengaluru in order to study solar power plants, analyze the performance and utility of VFD systems. The efficiency of the systems is studied by use of VFD with varying parameters, use of automatic solar structures and identified ways or areas to reduce the power losses which in turn could increase the efficiency of the system. By employing a dual-axis solar tracking system coupled to a low power micro controller and a low power low torque actuator, the model meets the desired capabilities of producing as much output power as possible while still being affordable to consumers. This system is adaptable to meet the needs of small-scale power production as well as the needs of a large-scale solar farm. (C) 2019 Elsevier Ltd. All rights reserved.
