Projektvorbereitung und -abwicklung des Bund-Länder-1000-Dächer-Photovoltaik-Programms

The report summarizes the present state of the 1000-Roof-Photovoltaic-Programme (sponsered by the BMFT and the Federal States) in the five new German Federal states. After some starting problems the programme is well accepted also in East Germany now, especially in Brandenburg, Saxony and Thuringia. Statistical data are given on the siutation in the single states.
Some operation results are discussed in more detail. A final yield of 2 kWh/kWp.a seems to be possible, at least in the region of Saxony. The share of the direct used solar energy by the plant owner strongly depends on the individual energy consumption and on the season. During the winter only a share of 10 % is realistic, but in summer the value can reach 50 % or more. The average performance ratio of several systems is estimated to 68 %.
