RETRACTED ARTICLE: IOT based statistical performance improvement technique on the power output of photovoltaic system

Abstract

Green electricity gains emphasis not only due to technological progress but also because of deployment of non-renewable energy resources and abundant of renewable energy resources. Global demand for the power increasing yearly is met with the help of green energy. The sources which paved the way for green power generation are solar, wind, tidal etc. The parameters of green power generation to be monitored becomes essential to enhance the power output. Without human interaction there is a simple and easy way for monitoring the parameters, with the help of Internet of Things (IOT). Among available resources PV (Photovoltaic) plant generation is advantageous among all other resources because of easy installation and power production. PV plants of MW capacity are sometimes installed in very remote locations. Interfacing the plant using internet helps to monitor and evaluate the performance of PV arrays continuously. Performance impairment could be due to several factors like drop in efficiency, hotspots, manufacturing defects, insufficient insolation, shadow, orientation of panels, soiling etc. Quality control and good engineering practice helps in overcoming most of these factors. Soiling or accumulation of dust is one important factor which requires frequent attention as dust accumulation will hinder the light reaching the solar panels. PV panel orientation varies throughout the dawn and based on geographical location tilt angle varies throughout the year. For curtailment in losses due to orientation, tilt angle, accumulation of dust, an integrated smart system with wireless technology is proposed in this paper.
