Design of an Internet of Things Environment Based on Hysteresis Control in a Photovoltaic Panel Controller for the Massive Use of Solar Electric Energy in Urban Areas

Abstract

A controller of photovoltaic panels was designed to take advantage of solar electric power, facilitate and promote its use in urban areas; the controller connects with a server to send data of its status and also request important information that will change the hysteresis that helps its autonomy and efficiency, the information that server provides is based on a statistical analysis, the variables analyzed are the voltage on the photovoltaic panel that is directly proportional to the radiation of the sun and the battery voltage that is directly proportional to the amount of energy stored; the data is obtained from other controllers who also communicate to server, acting as sample collectors; this is how the Internet of things environment is formed, a large network formed by controllers that collaborate with each other. In the most basic form of the controller, it works by managing the solar electric energy, determines when solar electric power is supplied to the load and when to switch a circuit to provide power from the conventional electric grid.
