The German government Monday passed a bill that foresees further reductions of subsidies for electricity produced by photovoltaic solar energy--such as rooftop facilities--depending on the amount of generation capacity added each year.

However, a one-off cut to solar energy subsidies that Environment Minister Norbert Roettgen last week said was being considered by the government, and that was included in a draft of the bill dated May 30, was deleted without replacement.

According to the bill, published on the website of the Environment Ministry after a cabinet meeting earlier Monday, the government decided to maintain its system of reducing solar subsidies by a base rate of 9% each year. This base will continue to be complemented by a variable percentage rate, depending on the how much new generation capacity is installed.

On top of the subsidy cuts at the beginning of each year, the government intends to cap financial support further for solar facilities that are newly installed in the second half of each year--again depending on how much capacity has been added previously.

Roettgen's proposal to reduce solar subsidies by a further 6% in a one-off cut effective March 2012 has been scrapped, according to the bill.

Germany promotes photovoltaic solar energy facilities--mostly rooftop installations--through feed-in rates that guarantee minimum prices for the electricity they generate. Effectively, electricity consumers are paying for subsidizing renewable energies.
