Assessment of Fluctuations in the Efficiency of Electrical Energy Generation in Standalone Photovoltaic Systems Due to Variations in Ambient and Solar Panel Surface Temperatures in the Historic Center of Popayán City.

Abstract

Global energy demand has led governments to diversify the energy matrix with renewable energies, in addition to integrating technological improvements in existing ones such as photovoltaic solar energy; in this type of energy generation, it has been observed in different studies that There is a significant influence from variations in ambient temperatures and on the surface of the solar panel that directly affect the efficiency in the generation of photovoltaic electrical energy. Therefore, this experimental research proposes to address the efficiency of this type of energy under the environmental temperature conditions in the historic center of Popayán. Due to the few studies on the subject in the region, the present research based on the V-Shape methodology evaluates the different electrical characteristics in polycrystalline solar panels through the development of a hardware component made up of an embedded system and electronic instrumentation and the software component through the development of an application that allows the processing of the information collected to perform calculations on the necessary parameters for subsequent recording and analysis, giving the research a quantitative approach and a descriptive scope.
