Control of Water Pumping System Based On Floating Photovoltaic System with a Solar Tracking Control

This paper presents a solar tracking control of a floating photovoltaic system using a submerged water pumping system. Addressing the issues of limited space and overall efficiency represents a significant challenge in the realm of renewable energy, particularly in the context of photovoltaic systems. The floating solar tracking system offers a viable solution to enhance both surface and efficiency. To feed efficiently the system where the light intensity is higher and energy is in the form of Direct Current, tracking is the alignment of the solar panel so that it is always perpendicular to the sun beams. Thus, this work is divided into two parts; Based on submerged pumping systems, the floating solar tracking system is modeled and controlled. The practical application of our work’s experimental model is covered in the second section. The use of a photovoltaic panel coupled to a DC-DC Boost converter powering the two submerged pumps allowed us to implement the concept of floating solar panels with the pumping solar tracker. To indicate the direction of sun radiation, these pumps are coupled to the L298d circuit and controlled by an Arduino mega.
