New Prototype of Photovoltaic Solar Tracker Based on Arduino

Abstract

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.

Optimization of light-dependent resistor sensor for the application of solar energy tracking system

“…So captured power is increased include and exclude cloud effects, sunrise and sunset. Existing sun-pointing sensors with tracking control parameters used in solar tracking applications [2] such as photosensitive sensor is operated with differences of currents of photodetector [3], four quadrant LDRs are isolating the light from each LDR and sun position is measured by resistance sensitive comparison method [4], optimal azimuth and tilt angles of the sun measurement based on brightness and shade of the sun [5], measurement of the sun position using difference of voltages by means of comparator with four quadrant LDR [6], a design consists of two photodiodes and a metal wall creates light, shadow and differences of currents [7], four monolithic photodiodes with a transimpedence amplifier are used to measure elevation angle of the sun based on difference in voltage of the photodiodes [8], maximum light detection sensor applied in solar energy generation [9], and power of photo-diode sensor [10].…”

Desenvolvimento De Um Protótipo De Rastreador Solar De Baixo Custo Utilizando a Plataforma Arduino

“…Por sua vez, os rastreadores solares agem para que os painéis mantenham essa posição em relação à radiação solar. São chamados sistemas automatizados e movimentam os painéis em conformidade com o movimento do sol, resultando num máximo aproveitamento de energia solar [1]. [2], classifica os rastreadores solares em duas categorias: passivos e ativos.…”

Design and Control of a Permanent Magnet RotLin Motor for New Foldable Photovoltaic Units

“…Traditionally, mechanical trackers for photovoltaic applications are complex and the entire volumes of mechanical trackers are relatively large and cumbersome. A mechanical tracking system is investigated for the photovoltaic device [19] by using mechanical transmission. To reduce the number of tracking motors and the whole weight of the tracking systems, the integrated design of the motor is useful for improving the performance of the power generation system by eliminating gearboxes.…”
