Energy and economic analysis of the use of photovoltaic in energy systems

Energy policy of Poland in a balanced way has to provide security of energy supply, increase the use of its own resources and promote the sustainable development of different electricity generation technologies. The established aims of climate and energy policy will be difficult to achieve without efficient technologies based on distributed generation. In this context, the importance of the development and use of photovoltaic systems is growing. Photovoltaics is one of the most promising technologies and the possibilities of its use in various scale energy systems make it an effective and safe source of energy and an important part of a stable and independent energy mix in the future.
