|9.6 kWh in a single February day!|
However, we have the odd statistic that the GSHP consumption exceeded the House consumption, an unusual event that only occurs on days which are very cold, but have high sunshine, enough PV to wipe out the consumption of the house. The GSHP exceeded 30 kWh in a day, the first time since December 2010 (I left the heating on, even when we went out for the afternoon).
The perfect bell curve above is slightly biased towards the morning, because of the easterly orientation of the PV panels. The PV annual has tipped over the 3,400 mark which is odd, because they cannot be tuned like the Heat Pump, they either work or they don't. It shows that we have had statistically a lot more sun that in the previous two years.
