After confusing several of you and certainly myself, I grabbed an old electric bill to determine our actual usage. Now, I don't have any clue how to translate this usage in the necessary size for a solar array. Here's what my bill indicates as my usage: May 2006: 1117kWh Daily average looks like it peaked in winter at about 42kWh per day. So, what does this mean for a solar system? Any help would be greatly appreciated. Thanks!
