Operational characteristics of photovoltaic systems

Current efforts to open up the practical education to broad group of interested students, leads to still greater development of so called virtual laboratories. E-learning is becoming an important part of teaching at universities. The paper describes one of the developed laboratory exercises, which was created with the intention of remote access. It is a photovoltaic system with the accumulation of power, where the students can simulate various operating conditions. The idea creates a virtual laboratory tasks have established according to the actual situation in the development of energy systems with renewable energy sources which is currently in the spotlight. Czech Republic is no exception in this regard. Dynamic changes which happened in legislation concerning photovoltaic systems opened up the possibility of increased development of hybrid energy systems.
