Deal in Germany sets 52GW cap on PV support

 The news from Germany puts an interesting cap on PV levels eligible for feed-in tariffs: first the news, then the math:

Germany sets 52GW cap on PV support as FIT deal is reached -Recharge
Picture from source article
German legislators have hammered out a compromise deal over cuts to the nation’s support regime for PV installations – which will now end altogether once 52GW of capacity is in place.

As well as setting the 52GW "absolute upper limit" for support – roughly twice the figure currently in place in Germany – the agreement maintains an annual growth target corridor of 2.5GW-3.5GW. The country installed 7.5GW in 2011 alone.
The entire article can be read at Recharge: The Global Source for Renewable Energy News

The math:
At a 10% annual capacity factor the 52GW would produce ~45.5TWh of electricity, which is ~8.5% of Germany's annual demand.  This ignores that combined with other renewables (wind); the output from wind and solar will increasingly be more than the grid can handle, and will have to be curtailed.

Solar will therefore be held to replacing only 25% of the nuclear capacity that the Energiewende requires replacing.
More information on the new FIT rules is at the German Energy Blog, including:
The Bundesrat also informs that the government pledged to set up a new support programme providing loans at reduced rates of interest for decentralised storage facilities. To this end the government reportedly wants to provide funds of EUR 50 million as of 1 January. Besides, the government seems to have announced to raise funding for research into regenerative energy systems, application-oriented photovoltaic systems and production technologies considerably. The pledges have been made in a statement for the minutes, and are not part of the formal compromise of the Mediation Committee, the Bundesrat points out.
The full text of the compromise is available here. The compromise proposal is on the agenda of the Bundestag for 28 June 2012.
