Power supplies for remote houses without a grid connection represent a very attractive market for photovoltaics. Even in highly industrialised countries there are many inhabited houses which are not connected to the grid (10,000 estimated in Germany, about 300,000 throughout Europe). For these buildings, the cost usually rules out a grid connection. Up to now, the only option available for the residents was the installation of a diesel generator with a high pollution level and a discontinuous power supply. Environmentally acceptable photovoltaic AC systems can now be constructed, using a special inverter recently developed at the Fraunhofer Institute for Solar Energy Systems (ISE). The quality of the alternating current is identical to that supplied by public utilities. The high efficiency value of the inverter, which is maintained even for very low partial loads, allows the inverter to operate continuously without reducing the system efficiency.
