Abstract:
The sun is part of our life and has an important role because it warms the earth, the water in the oceans evaporates thanks to it, the clouds are directed by air currents determining the rains and maintaining the flow of the rivers. Fortunately, solar energy can be converted into electricity in an environmentally friendly process. Photovoltaic panels are a clean and environmentally friendly source of electricity. Obtaining this energy, however, poses a number of challenges for device and equipment designers. The amount of energy produced by the panel strongly depends on the angle of incidence and the intensity of the light falling on the surface of the cells. This, in turn, leads to instability of the output power parameters, since even shading of a small part of the panel can cause a drastic reduction in efficiency. The elegant solution would be a system of photovoltaic panels that can track the position of the sun for optimized electricity production. In this context, our aim is to design and build a sun tracking system. The experimental photovoltaic system contains the following components: solar panel, panel fixing system, inverter, connectors and cables, the sun-tracking system, mega jade development boards, current measurement and regulation equipment, batteries, etc. Stepper motors, different types of wheels for panel orientation made on ender and Prusa 3D printers, bearings for rotating the rods were used for the sun tracking system. After the experimental device was built, it was tested under relevant conditions. The data provided by the inverter was analyzed in terms of energy produced in relation to weather conditions.
