The technology of photovoltaic has been identified in Europe as a major source of electric power generation for the future, but the still high costs of this technology require subsidies to boost photovoltaic electricity generation. In Austria, Germany, France and the United Kingdom support schemes, based on feed in tariffs, have been introduced to reach this target. But which business models are adequate to increase the share of photovoltaic power generation and how do the national supporting schemes affect these business models? And what will happen, when supporting schemes are fading out? To evaluate appropriate business models in the four countries, the structure of the national schemes will be identified and feasible business models will be introduced, taking size and location of the photovoltaic power plants into consideration. In France and Austria the 100% feed into the grid business models is at the moment the best solution. In Germany partial self consumptions could offer better results and in the United Kingdom self consumption is superior to 100% feed into the grid. Nevertheless all business models are still depending on the national supporting schemes. In the future business models under absence of supporting schemes will be possible, when the initial invest for photovoltaic power plants will decrease significantly and the lifetime of the plants could be extended to a range of 40 years.
