Did the return from our bike ride on Easter Sunday in the pouring rain, though no head wind. Felt quite good oddly enough to be out in the rain. Sun came out in the afternoon for a bit.
Strangely, my wife has several solar lights in the flower pots on the balcony. We have had quite a few sunny days, but they have not charged.
After the driving rain in the morning and then the sun, they were all on last night. Perhaps they to have heeded the wetness and changed over to rain charging!
