*As shown on the electricity account for the mains electricity used at times the PV panels were not producing (night, overcast conditions, or when our draw exceeds our generation). Note, however, that as we export more solar power into the grid than we extract, the panels could be considered to offset the entirety of our power carbon footprint.

The Meeting House uses power over the entire 24 hour perod, and solar energy is only produced in daylight hours. Even so, the table above shows a reduction in our draw from the grid of over 25% compared to 2007 and a large export to the grid that occurs during the daytime when there is little draw on power.

Most night-time power uses such as lights have already been converted to low energy globes, so items with a steady draw are the probable cause of the resistant grid draw. As the HWS is only switched on "on demand" the most likely appliance to further reduce grid draw would the the refrigerator. This will be replaced with a more energy efficient model when it reaches the end of its life.
