A record month that is going to be hard to beat! 78.7% above expected levels for December, which is less remarkable than it sounds if you'd seen the mild weather we had.
In fact, I would have preferred a less efficient solar month in exchange for some proper crisp, snowy Christmas weather!
One thing we did get a lot of was extremely high winds. So much so that I did sometimes check all the panels were still in place. So far though all seems well - we really are very exposed to gale force winds here, so hopefully that will help reassure other solar PV owners worried about the effect of high winds.
Our total output was less than November, but we are still regularly generating around 1,800W.
Last month I wondered if December would see us hit our yearly target four months early, but it wasn't to be - we were 99.8% of the way there though - so close! You can see our yearly graph here.
In the graph below, the yellow line indicates the average level we needed to reach each day (2.49kWh) in order to meet the predicted monthly total. The blue line shows the average level we actually reached (4.45kWh).
