“…This system has been field tested for five days in cloudy winter (end of July and early August 2012), the result is quite good with the total tracker consumption with both motors operating at 67.8 mA. Thus, in such weather conditions there is a relative surplus of 38.98% [24].…”

This paper presents the use of sunlight trackers to increase the efficiency of solar panels. The sunlight tracking is done by passive and active tracking method with one or two axis. The active trackers use an electrical motor as a driver and can be controlled by a microcontroller or a programable logic controller (PLC) according to the direction of sunlight. The use of this controller in sunlight tracking system performed in real time or periodically. The position of the sun as a controller input can be obtained based on azimuth angle and solar elevation angle or by direct measurement using sensors. From the discussion is obtained an increase of efficiency of 29.37% in avarage using the active tracker.

“…There are many methods of sun-tracking that have been proposed to facilitate the tracking of the sun's position with a high degree of accuracy [13]- [16]. The panels can absorb the maximum energy in the noontime, where the rise of the sun is at zenith and the values of the solar radiation are maximum.…”

Pumping water is one of the most popular technologies of solar energy for irrigation or drinking water supply. Its performance depends on the characteristics of the site (sunlight, ambient temperature, geographical obstacles), on the performance of the modules, as well as, on the characteristics of other equipment (converter and pump). The optimal sizing of a photovoltaic water pumping system makes it possible to guarantee the satisfaction of the water demand throughout the irrigation period and to model the electrical energy needs to supply the pump to irrigate the crops and water livestock. This paper proposed a novel algorithm for dimensioning the elements of an autonomous photovoltaic system equipped with irrigation water storage. The proposed algorithm determines the optimal surface area of the photovoltaic modules and the electrical power necessary to satisfy the water requirement for irrigation in the observed time. The results obtained from the proposed algorithm for optimal sizing are compared to calculation scenarios to show better results. A case study from the Fez-Meknes region in Morocco has been selected for applying the optimal sizing algorithm.

“…Tracking in closed loop is more effective as it uses various active sensors responsible for receiving signals of solar radiation, such as light-dependent resistance (LDR) or charge-coupled device (CCD), and moreover, it has a feedback to the controller that allows constantly orienting the panel making the most of its effectiveness [20,21]. At the moment, when an error signal previously calibrated coming from the control system is produced, the motors are activated and the surface of the panel is redirected [22,23].…”

Abstract:The global increase in energy demand and exponential exhaustion of fossil recourses has favored the development of new systems of electricity production. Photovoltaic solar energy is undoubtedly one that has the highest application in housings, due to its simplicity and easy implementation. In this work, a new prototype of photovoltaic solar tracker with Arduino platform was developed. Feedback control system that allows carrying out solar tracking with two axes using a stepper motor and linear actuator was established through an electronic circuit based on photodiodes. Moreover, real construction of the prototype was carried out, where the effectiveness of the design and its capacity to draw a maximum benefit of an incident radiation can be observed, placing the panel perpendicularly to the received energy and improving its performance for its application in future installations in housings. Results obtained from the comparison between the developed prototype and a static panel oriented according to the latitude of the area, show about 18% energy gain.
