Our SDHW installation didn’t go operational until January 2011. We have a poor site for solar, especially winter solar. In January, the SDHW panel doesn’t see sun until 11:30 AM, and it’s in shade again by 3:00 PM. Even so, in January and February we made hot water any day that the sun was out. Proceeding into March, we’re beginning to make all the hot water we need even on days with light clouds. Can’t wait for April and May!
