Nowadays renewable energy sources are becoming more and more important in the consumption of electricity. Due to the European Union regulations, member states are obliged to decrease the ratio of fossil fuels in their energy sector while aiming to use „green” energy sources.
The aim of my thesis is to review the legal situation about the feed-in of household photovoltaic (PV) system to the electrical grid. In addition, I will examine the reasons why the domestic spread of PV systems has failed to reach the same extent, as in Germany, and I will make suggestion to promote developments in Hungary. Furthermore, I am going to work out a general method to assess the return on investment of PV systems, which has not been available before.
In the further sections, the following topics will be presented: basic principles of PV and its types, EU energy policy, legal background about the feed-in of small scale PV to the grid in Hungary and Germany, the similarities and differences in the financial support system in the two countries, and proposals to improve that system in Hungary.
