| My solar output from my thin film dropped to just over 1 hour full output per day average for December 2007. Even though we are 43 degrees north I got a whole lot more last winter. I looked at this http://www.weatherunderground.com/history/airport/KDLL/2007/12/15/MonthlyHistory.html
and it kind of shows why I had little output. We also had about 36 inches of snow in December so of the 5 days with sun there was usually 6 inches or more of snow and ice on the panels for at least part of the day. |
