Energy prices are increasing all the time. Further worldwide supplies of fossil fuels are decreased. These supplies will be exhausted in the future. Therefore, it is necessary to find new energy sources. The direct transformation of solar energy into electrical energy through the use of photovoltaic cells is one of the possibilities. The aim of this paper is to illustrate the working principle of the photovoltaic system FVS 2001E that is located on an external wall of a building of Tomas Bata University in Zlín.
Solar energy belongs to clean renewable energy sources. There are a lot of transformation methods of solar energy into another kind of energy. The direct transformation of solar energy into electrical energy by means of photovoltaic cells is one of the possibilities. The aim of this paper is to describe single types of photovoltaic systems and possibilities of their applications. and Solární energie patří mezi čisté obnovitelné zdroje energie. Existuje mnoho způsobů transformace solární energie na jiný druh energie. Jednou z možností je přímá přeměna solární energie na elektrickou energii pomocí fotovoltaických článků. Předmětem tohoto příspěvku je popis jednotlivých typů fotovoltaických systémů a možnosti jejich aplikací.
