Solar Concentrator System with Automatic Tracking System
Žák, Martin ; Sumec, Stanislav (referee) ; Baxant, Petr (advisor)
This master’s thesis is focused on current possibilities of solar energy utilization – especially on concentrating solar power systems – and their optimization using solar tracking systems to maximize energy gain. The thesis also deals with solar position algorithm and offers an Arduino based automatic dual axis solar tracker design which provides various solar devices the ability to pivot using stepper motors, DC motors or servos. The motion might be driven by calculated solar position or by actual illuminance.

Positioner for Solar Panel with Power Efficiency Optimizing
Kreysa, Karel ; Punčochář, Josef (referee) ; Šebesta, Jiří (advisor)
This thesis is focused on design and prototyping of solar panel position control system for an obtaining of the maxima renewable energy from sun. In this thesis, various ways of solar panel positioning are considered and analyzed. Consequently, a construction arrangement of the positioner is presented. It is mechanically adapted to obtain the maximum efficiency in typical environment corresponding with the Central European geographical latitude. Different methods of sun monitoring are considered and analyzed. On the basis of this analysis, a proper prototype of sun monitor for exact positioning with disturbance filtering has been constructed. Following part of work is devoted to stable, fully automated, control subsystem for reliable functionality of solar system. A suitable microprocessor with a robust firmware has been implemented to this control unit. Finally, system parameters measurement and closing analysis of gained renewable energy and backflow computation is presented in the end of this diploma thesis.

Photovoltaic battery charger with sun tracking
Knob, Martin ; Frýza, Tomáš (referee) ; Kufa, Jan (advisor)
This thesis describes the design of photovoltaic battery charger. The charger can tracking the Sun and tilt the panel in azimuth and elevation. The device includes an MPPT regulator to optimise the energy produced by the photovoltaic cell from the Sun. This photovoltaic charger is designed to charge Li-Ion batteries and includes appropriate charging and protection circuits. The charger is energy self-sufficient, which means that it does not need an additional power source. Another purpose of this device is to measure electrical quantities. The device sends the measured data wirelessly via Wifi.
