“…The results of the current study showed that the potential of the use of trackers associated with photovoltaic panels should be focused on the economic aspect of the investment. In tropical regions with high rain index or cloudiness, the tracking system might not be as efficient as foreseen (Rambhowan & Oree, 2014). More in-depth studies with much more extended duration are necessary in order to be further specific in recommending the proper panels to be used in rural areas of tropical countries.…”

The demand for energy and the pressure for reducing environmental impacts is increasing in developing countries, mainly in agricultural areas. The generation of electricity from photovoltaic panels can be economically and environmentally advantageous as a source of renewable energy and the ability to reach remote consumers. The present study aimed to evaluate the performance of a photovoltaic system equipped with a sun-tracking device, comparing to a fixed panel. The test compared two panels of a photovoltaic cell system, one used a rotation module in two-axis, and the other a fixed one (control), for capturing solar energy throughout the day in a tropical region of Brazil. Solar energy data were obtained in the two photovoltaic panels with data continuously recorded six months, with a weather characteristic of high cloudiness and rainfall indexes. The commissioning of the tested photovoltaic panels was done on bright days. Power results indicated that the two-axis tracker system was useful during the test, presenting an increase of 26% when compared to the fixed panel. It was found that when the cloudiness and the rain index are very high, the sun tracking system might not be as efficient as foreseen. Rainfall and cloudiness index are essential factors for determining the feasibility of using a tracker device in tropical regions.

“…A key disadvantage with solar tracking systems is that the power used by the driving mechanism is often taken away from the output power of the solar panel, decreasing the net energy gain (Rambhowan & Oree, 2014). Therefore, the present study aimed to propose a solar tracker that could be efficiently used in rural areas.…”

“…In modern PV modules, small electronic components are used as a part of the modules and are called bypass diodes. These diodes allow the current of un-shaded cells to be bypassed through shaded cells, usually, every module has two or three bypass diodes [16][17][18].…”

This paper presents the simulation of a dual maximum power point tracker (dual-MPPT) and attempt to get the global maximum power point GMPP under partial shading conditions for a solar photovoltaic module using MATLAB SIMSCAPE. Traditional single MPP trackers are less efficient than dual MPP trackers and have greater sensitivity to partial shading. By using dual MPP trackers, one can get several features such as the possibility of connecting two arrays with different string sizes or different solar azimuths or tilts within high efficiency. This paper focuses on making the photovoltaic system work at maximum possible power under partial shading condition by using dual MPP trackers to achieve the convergence toward the global maximum power point GMPP.

“…A dual-axis solar tracking device was structured utilizing an LDR sensor, DC motors and a microcontroller to make it equipped for the uninterruptible supply of electricity for rural applications [13]. A research team presented a noble design for tracking mechanisms using a three-fold strategy and found that the tracking system shows a power output conversion efficiency of 43.6 % in comparison to fixed-panel [14]. A fixed panel system is less efficient in comparison to a moveable tracking system is the fact it does not rotate as a result at times they are unable to capture the maximum intensity of sunlight.…”

Solar energy is one of the most effective resources because of its cheap source and its reliability to sustain. The best way to attain the maximum possible efficiency from solar panels is to use tracking devices. Solar tracking will contribute significantly to increasing the efficiency of energy collection from the PV panels. Trackers can either be the single-or dual-axis. In this work, we have presented the designing and performance analysis of the dual-axis solar tracking system in comparison to the fixed panel system. We have determined the output power generated by a dual-axis solar tracking system is more than the fixed panel system. The outcome of the dual-axis solar tracking system has been analyzed and compared with the fixed panel system has been highlighted and it has shown better performance in terms of voltage, current, power and battery charging capabilities. Dual-axis trackers give more energy as it tracks sunlight in both the direction. Hence it is more efficient than fixed panel.
