Weather wasn't all that bad yesterday, he said; writing retrospectively.
PV cells got Battery up to 100%, for however short time 3rd day running - BUT - you can see what a wet Dandelion Clock looks like after night's rain and an hour or so's Sunshine?

Today, on the other hand it is, as a deceased mate of mine was wont to say, "rainning PISSistantly", with, at almost 11:00, marginally in excess of 0.3kW generated and the Battery has been @ ≈ 40% since about 05:00, when it had slowly dropped from ≈ 65%.
