nesmail2 years ago000Does this require direct sunlight exposure to charge? Can this run only on battery supply?ariovillars2 years ago • purchased this product000purchased this product Helpful answerHi, we installed it and we have very little direct sunlight but it works perfectly. Commentthomashuwyler2 years ago • purchased this product000purchased this productI use it in a place with approximatly 2 hrs. of direct sunlight exposure. Since it does not switch on often, it's enough for charging. I don't know, if it works on battery supply. Comment
