Yesterday, March 3, 2107, was overcast and gray all day long. We even had some light showers. It was probably a worst case day for solar energy generation. Even so, we generated 28 percent of our energy from the sun. This ends. a series of very good days up in the 80 percent range. Our best days are ahead in the months of April and May. My energy efficient window replacement project should be done by then so I am optimistic about how well the system will perform then. The time-lapse for the day reveals some opportunities for generation were available in the morning.
