Jan 14th - Perfect Day

January 14th was a near perfect day weather wise and was my most productive day to date with 11.3 kWh generated. Clearly this will get surpassed later in the year, but it's quite impressive for January, when an average of less than 3.5 kWh is predicted.

The detailed plot for the day (below) is almost perfectly smooth, with just a couple of dips, so I suspect this is about as good as it can get for January. The early bias on the chart show the impact of being SSE facing, but it's hardly a major problem. I think the slow pick-up at the beginning of the day and the early and late dips are caused by trees on the horizon. Although I don't suffer from shading on the panels, I do have a broken horizon with lots of trees in the distance. Hence why the plot isn't exactly smooth. As the sun rises higher in the sky these will cease to be a problem, so it's not something I should worry about - not that I can do much about it anyhow.
