The shorter days are starting to show up on our daily Kilowatt collecting. In June we were getting 105 to 116 Kilowatts per sunny day. Now in November, shorter days but the nice blue sunny sky we have had these last few days, has moved the Kilowatts to 60 - 65 KW per day. Which is still very good. That is twice what a normal house in the upper Midwest would use (30 kw per day).
November and December are usually the cloudiest months of the year. So we are happy to be experiencing the sunshine. You can see in the pics here how the snow affected my garage and solar ground mount.
Here I have the solar panels at the winter angle of about 61 degrees for our Latitude. At this steep angle, unless it is a very sticky snowfall, I do not think the snow can stick to the panels at all.
Here are our solar numbers for October. 1.41 MegaWatts or 1410 Kilowatts.
