Abstract
For years, solar energy has been a subject of study for electricity generation as an alternative power source. The main objective of this project is to carry out a comparative analysis of the production of electrical energy between fixed photovoltaic panels and those with tracking systems on one axis. Three solar modules were designed and built with the same technical characteristics but different solar tracking systems; Single-axis tracking systems will use tracking systems by astronomical programming and light tracking by LDR sensors. Current, voltage and temperature sensors were implemented along with software capable of obtaining the characteristic curves of the production behaviour in each prototype. The data processing, as well as the management of I/O signals coming from the different electronic components associated with the operation of each system, are governed by an Arduino mega board linked to an Ethernet module to be able to observe the curves of production from a website, all operating automatically. Therefore, we determined that the PV system by astronomical programming is the most convenient, due to its lower energy consumption when correcting the panel's position.
