Since there is nothing to complain about. Once these lights abkriegen even a little sun, this place going on in the dark and exhibit great endurance. I have set up my a week ago (ie in mid-March) and the panel receives from only a very short direct sun. Nevertheless the lamps until late at night! When exactly this up, I can not say I was not yet so long awake. Only so much, yesterday it was half 2 and the things shone still (albeit a bit weaker).
However, one must say that the last days have been very sunny and beautiful. It looks like rain after a week remains to be seen. I'll be the day in any case a few order me about it.
