Utilization of renewable energy sources tends to increase due to growing global power demand, reducing cost of renewable technologies, diminishing fossil fuel supplies and the increasing awareness of environmental protection. Solar energy is harnessed using a range of technologies, out of which photovoltaics is an emerging field of application. Solar cells convert the energy of light into electricity by the photovoltaic effect. The efficiency of a solar module can be increased by the installation of a solar tracker system.
The aim of this project is to introduce the theory and working principle of photovoltaic cells, PV systems and solar tracking mechanisms. Required functions of a dual-axis solar tracker system capable of providing power for a device with low energy demand (e.g. portable radio or emergency light) will be determined. The mechatronics model of the system will be created which is followed by electrical, structural and algorithm design. A prototype of the designed system will be realized by means of mounting structure manufacturing, component selection, electronic assembling and software implementation to a microcontroller.
The system will be tested, the design process and realization evaluated and further development possibilities will be proposed.
