Island systems / Stand alone systems

Photovoltaic plants called stand alone systems, which are not connected to the public electricity grid. The produced power is stored in accumulators as direct current. This kind of the photovoltaic plants is suitable for the power supply of unexplored or from electricity grid cut off regions (mountains, rural areas, developing countries). In developing countries the influence of the photovoltaic plants grows, since the power supply can be guaranteed, without waiting for the development of electricity grid and the infrastructure.
