Photovoltaic system for RAPS applications
 Nevoral, Miroslav ; Bača, Petr (referee) ; Křivík, Petr (advisor)
The beginning of this work presents the basic principles of photovoltaic cells, their advantages and disadvantages. There is also an overview of photovoltaic systems. The next part takes a closer look on lead-acid accumulators followed by a practical part regarding the measurement of VA characteristics. The main goal of this work is to assemble an experimental PV system. It will consist of a PV module, an accumulator (consisting of two cells connected in series and producing an overall voltage of 5V) and of a variable load (assembled from nineteen resistors with resistance varying from tens to hundreds of Ohms). This system is connected to a computer that runs the control software which was created using the VEEPro 8.0 simulation environment. The measurements can be taken in two ways. Either the operator can select the load resistor combinations manually, or the operator only launches the measurement and the load is selected automatically by the software. This way we obtain an automatized workplace for measuring VA characteristics of photovoltaic panels.
