We haven't even had our solar array active on the farm for a full year yet and we're still learning a great deal about it.
For example, we've learned that even on cloudy days, solar panels are usually able to pull at least a little bit of power out of the highly filtered sun. It takes a truly heavy cloud cover, with no breaks to shut them all the way down. On the other hand, we have seen no evidence that a full moon provides anything that registers as power production - despite the fact that a couple of sources make claims that this is possible.
Above is a graph showing the production for the past week, including today so far. Yesterday, April 4, was very nearly a perfect day. However, you might notice (click to see the bigger view of this picture) a couple of notches in the curve. These are points where a high cloud floated by and briefly obstructed the sun - even if only partially. April 3, on the other hand, was pretty cloudy all day long.
But, March 30? That was a perfect day. And, it looks like today is on the way to trying to reach that same goal.
I guess we'll have to get the camera out today as well. Let's see if we can capture another perfect day.
