Overview:

Monthly energy production in 2009


Comment: In April, the datalogger did not work for a few days, Monitoring started mid January

Monthly energy production in 2010


Monthly energy production in 2011


Comment: On June 4th 2011, a thunderstorm triggered the AC circuit breaker which in turn prevented the inverter from working. The breaker was manually reset on July 12th 2011 (unfortunately losing 39 days)
