In a new report (PDF in German), the German edition of Photon forecasts growth of 3 to 4 gigawatts of photovoltaics next year in the country despite all the talk about falling rates. If that figure holds true, photovoltaics will come close to making up two percent of Germany's electricity supply next year.
Photon puts the newly installed capacity for 2008 at 1.93 gigawatts. Starting in 2009, we will have official figures from Germany's Network Agency, which began keeping a registry of grid-connected PV systems on January 1. A few years ago, Photon began collecting these statistics itself (collated from grid operators) because no figures were officially collected.
There is one really nice statistic in the article: Bavaria was the first German state with approximately one solar module per capita on the average (188 watts per person) -- and that was in 2008.
