The Sun is out in west Scotland with a vengeance and the units are clocking up with gusto. It's been gladdening to see generation return to high levels and there ought to be no impediment to exceeding my target amount. With the current sunny weather, the panels have been achieving over 19 units a day.
A week ago, I had a visit from the chap who installed the system. I pointed out a long flow of bird pooh that had run halfway down one of the panels and up he went to clean it off. Apparently, tests done by his colleagues showed that even small areas of shading have a profound effect on the entire string of cells. Since they are connected in series, the shaded cell acts like a resistor and impedes the flow of power. He gave the panels a quick once-over while he was up.
Now to the figures.
My annual average is 7.02 units, having passed the 6.79 figure required to hit target a week ago. 30-day average is a healthy 12.19 units. Here's the graph that covers the life of the panels.
To see better the recent improvements, here's the last two months. Remember, red is the 30-day average and yellow is the overall average.
