Resumen

The agricultural sector is constantly evolving and agrovoltaic aim to address challenges such as climate change and water scarcity. The aim of this study was to design a pilot system to evaluate the effect of solar panel shading at two angles of inclination (10ºand 50º) on the growth and production of radish crops during winter and spring. The crop used commercial seeds planted in 1 m3 pots with a substrate of sand, field soil and peat. Plant growth was analysed under the shade of solar panels compared to a control group without shade. In addition, soil characteristics such as moisture, NPK content, electrical conductivity and pH were monitored using IoT technology for real-time tracking during the 40-day development period. Morphological parameters such as plant height, leaf area, bulb mass and root length were assessed. The results showed that the group exposed to a 10ºtilt angle had better plant growth, increased leaf area and higher productivity in both winter and spring. It was found that the 10ºangle resulted in lower water loss compared to both the control group and the group exposed to 50º. Regarding energy production, it was observed that the solar panels inclined at 10ºreached peak production, generating 1.016 kWh, surpassing the group exposed at 50º, which generated 0.805 kWh.
