August 2013 Reports

26 August 2013: Weather continues to be warm and dry, so different from a year ago.
  • House annual 5,407, biennial 5,223 kWh. 
  • GSHP annual 3,420, biennial 3,206 kWh, triennial 3,243 kWh. No change.... steady... 
  • PV annual 3,133, biennial 3,093 kWh, triennial 3,176 kWh. Slowly improving change.... 
  • Sunbox annual 3,120, biennial 2,839 kWh. Sunbox energy capture still improving, I wonder what the new top line will be. It is the combined figure for the two sunboxes, and does not include the tubes. 
  • Ground Temperature 13.5ºC. This seems to be a consistent summer temperature. 
12 August 2013: The nights are getting cooler and we have had hints of Autumn already! It's been a good summer though, compared with 2012. The days have been a mixture of overcast with sunny spells, but not much rain.

  • House annual 5,417, biennial 5,210 kWh. No change..... 
  • GSHP annual 3,427, biennial 3,202 kWh, triennial 3,244 kWh. No change.... steady... 
  • PV annual 3,102, biennial 3,096 kWh, triennial 3,166 kWh. No change.... steady... 
  • Sunbox annual 3,024, biennial 2,789 kWh. Sunbox energy capture is improving (with the help of the ETFE front panels), it has now gone past the magic 3,000kWh point! 
  • Ground Temperature 13.6ºC. This seems to be consistent temperature, there's been no significant withdrawal from the borehole store, but there must be some diffusion of the energy outwards.... until the heating season starts!
