Got the power bill for December, and it was almost as much as the summer bills. I think some of it has to do that it has been cloudy like 50% of the time, and I have had to kick on my water heater, since the solar part doesn't really work with the clouds. But also we have been keeping the house at 74 which might be a little too warm, so we have dropped it to 71. I notice the difference, but I just started to put on pants and that seems to do the trick. Also a shirt, and I am good to go. Hopefully this helps, or it is to the 60's we go....
I am a true Arizonan, and I don't think I could handle the house in the 60's
