Solar panels allow acquiring energy from the environment which can be stored for Energy Harvesting purposes. The objective of this work is to design, simulate and characterize different configurations in the harvesting stage, constituted by solar panels for energy harvesting systems of low consumption, identifying the most adequate arrangement to achieve the highest amount of energy together with the conversion stage. The methodology used has been design, simulation in Matlab-Simulink software and characterization with mini solar panels. The developed system consists of 3 stages which are: energy harvesting, DC-DC converter, and storage, focusing on the Energy Harvesting stage. The results obtained in simulation of 4.8V and 160 mA, and measurement of 4.60V and 134.5mA show that the mixed configuration is the one that presents better results in both voltage and current, concluding that the simulated and measured values are very close obtaining an error of 0.05% and 0.16% in voltage and current respectively and an output voltage of the converter of up to 26V. Finally, these results are very promising for Energy Harvesting applications. © Published under licence by IOP Publishing Ltd.

In the present work, a monitoring platform is made for an Axial Flow Permanent Magnet (AFPM) Generator without magnetic core, the objective is to permanently monitor the values that come from the generator, where the generator variables have been acquired through an open source development board called Arduino MEGA, which sends the data to a Raspberry PI, where they are displayed and stored so that they can be processed. The variables are displayed using the graphical node-red environment that offers a very eye-catching dashboard, which will be displayed on a 7 in. liquid-crystal display screen. All the data obtained is stored in a database that will allow its use for specific purposes. The monitoring platform has been built with the ability to monitor the speed of the rotors, the voltage and the current of a phase and thus be able to process the total power supplied by the generator. As a result, the monitoring system is a promise component for Pico Hydro power station to control the power all the time provided by the Axial Flow Permanent Magnet Generator. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
