I have a refrigerator, but I only plug it in when I am going to be around a lot. It is in a cooler part of the building. By midmorning, the sun is on the array and I can use the computer or watch TV with the surplus energy. Often these demands are offset by incoming solar energy.

Many cloudy days around here are punctuated with bright sun for an hour or so in the midafternoon. That is great timing in my opinion. As evening comes and lights go on, my other electricity use trails off. Most of the time, my batteries are quickly recharged the following day.
