Feed-in tariffs have proven to be an effective instrument in supporting renewable energies. As a result of the dynamic price trend of photovoltaics, the actual number of systems installed has repeatedly exceeded initial government targets. Therefore, the support for new solar power installations by the German Renewable Energy Sources Act (EEG) has been adjusted several times. Based on the experiences with these adjustments, DIW Berlin analyzed how feed-in tariffs can also be used to meet specific installation targets. For photovoltaic (PV) systems of up to 30 kW, a model analysis indicates that a bimonthly adjustment of the tariffs for new systems, on the basis of installation volume, is a more effective instrument for achieving targets than the biannual mechanism employed to date.
