A friend just posted a link to a site that everyone who wants effective energy decision making should bookmark. It is titled Performance of Photovoltaics (PV) in Germany.
The site includes animation features that illustrate the modeled output of solar installations over the course of each day. The model used should provide a reasonably good match with actual output; it is based on reported production from a sample of installations spread around the country that represent 13% of all installed systems. (You can find out the details of the model by clicking on the link titled “Our Data Calculation Model” on the solar performance website.)
I did a quick scan through the month of January 2013. So far, the absolute peak performance was 5.7 GWe on January 12. Throughout the month, most days peaked at less than 2.5 GWe. This peak is coming from an installed base of 32 GWe spread throughout the country.
Here is a representative sample of the informative pictures you can discover. It shows the absolute maximum output from January 19, 2013 as 0.9 GWe at noon.
