I always thought that on cloudy days, the solar system would be ineffective. I was wrong about that. The REC panels we have are actually very good when it comes to low light production.
The two images posted show the sky and the production stats taken today, 5-18-2021, about 2:30 PM. We are in between rain deluges, with clouds lingering overhead and no site of the sun at all today. These two images will tell you that your solar system does not just go to sleep when the sun goes away.
