Geração fotovoltaica mais eficiente com técnicas de arrefecimento

Various factors hinder the performance of photovoltaic modules, including shading, dirt, temperature, intensity of sunlight, among others. Considering the natural heating that modules undergo throughout the day and the efficiency losses as a result, the use of cooling techniques becomes a viable option with great potential to minimize losses. In this context, the main objective of this study was to develop a simple yet efficient standard control and monitoring system for a photovoltaic power plant that allows cooling of the modules using water, aiming to increase output power, efficiency, and lifespan through a remote channel. The system was tested and evaluated in the city of Teresina, in the state of Piauí. And the experimental result revealed that with the cooling system under the module's surface, the temperature could be reduced by up to 19-21°C, resulting in an efficiency improvement of approximately 10% in energy generation.
