Solar panels – six months in

Following on from the first quarterly report I’ve moved the boundaries slightly so roughly longest day to shortest day gives us 1,125 kWh – this compares with our estimated generation of 2,300 kWh which it has to be said is a pretty good estimate so far.

A rough calculation seems to indicate that our comsumption is down by around 2kWh per day in the period September to December which seems quite good (11 to 9)
