Sunny February

20 Feb 2012: If there is no more sun this month, we will still have overtaken the total for February 2011. The annual total is at an all time record of 3,413.5 kWh, which is remarkable considering that there are no moving parts or tuneable parts - and the panels have relied on rainwater self cleaning well into their third year of operation.
   The one-day PV capture of 11.1 kWh was remarkable for a February day, and the Sunbox also did very well to get 16 kWh because it was cold and the GSHP was busy working - demanding heat - it had so much solar energy from above that it only used 14.7 kWh on a day which started with freezing temperatures.
