Data Acquisition System for Solar Panel Analysis

Abstract

This project introduces a data acquisition system for solar panel technologies, mainly for analysis and report purposes. The measured variables are the current and voltage generated by the panel so that the power and voltage curve can be plotted to analyze. The system is made up of two parts, the hardware that will be designed using an Arduino circuit board with a voltage sensor, a current sensor and a temperature sensor that feedback the modeled circuit based on Matlab and Simscape platforms. As an addition to the hardware system, an embedded system is designed using operational amplifiers to simulate a solar panel, this emulation is based on the mathematical model that gives our values for variables generated by solar technologies. For simulation of the modeling and plotting of the generated data, we propose the use of Wahba’s method, for smoothing noisy data using spline function. This model will serve as a research/experimentation tool for technologies that improve the efficiency range of a solar cell.
