Analysis of V-A characteristics of the hybrid photovoltaic system

Abstract

The Alternative energy sources become more and more important. The Energy of sun is for sure much more appropriateand ecologic source of power than the fossil fuels. This topic cannot be actual more at least in the Czech Republic and Slovakia alsowhere official authorities refuse to allow connection of new the PV power plants to supply network. This is because PV power plantis unstable source of power and prediction of supplied power amount is problematic. This could lead to overload of a grid or even totalblack out of system. Possible solution is to accumulate electric energy from PV to another form of energy. Possibility of energy storedin hydrogen is presented in this paper.
