If you did this in the daytime, sun shining, panel cooling off will give you that extra energy.I noticed a few days ago that mine were covered with pollen. I hosed them off, and it removed some of the pollen but not all of it. I've since ordered a 24' solar washing tool from EquipMaxx so I can do a better job. The water running off the panels the first time I hosed them looked like running mustard. I got a couple of hundred watts increase in output afterwards. (PS... the same tool through Amazon is $40 more!)
