Overview:
Monthly energy production in 2018 (kWh/kWp)
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 opened the AC breaker which in turn prevented the inverter from connecting to the grid. The breaker was manually closed on July 12th 2011 (unfortunately losing 39 days)
Monthly energy production in 2012
Comment: the datalogger probably had an issue, as the total yield in 2012 must be similar to that of 2011, as indicated by the grid operator's measurements
