Lower Austria wants to give impulses for the development and installation of photovoltaic. On the one hand to be react on the actual energy situation (climate change, shortage of resources and cost development). Another important point is to look at possible job-effects of an "new" fast growing technology. The Country has inquired whether a master thesis can show different subsidy systems and associated effects for Lower Austrians workplace should be estimated. A moderate development scenario 20% of the whole electricity consumption in the year 2050 is the guideline for the comparison. Out of this scenario 3 different subsidy systems were calculated - a pure feed in tariff system, a mixed system out of feed in tariffs and direct investments and a pure direct investment schema. To estimate the forecasting of the value of PV electricity 3 different variants were made. The experiences of the German EEG (job development, and costs for the state) were integrated and compared with the actual situation in Austria and Lower Austria. The results show that to bring a "new" and fast learning Technology foreward the pure Feed in Tariff system is the best. And to bring stability in a fast growing market the subsidy system had to be stable and predictable. This system is useful to make in a national act and not on country level. The possibilities to subsidies the PV sector for Lower Austria could be trough simple, focused additional funding (lighthouse projects, GIPV-systems, demonstration and research plants, subsidies for education).
