The panel we initially appeared solid processed. Stable and strong material pushbuttons protect cells in transit. However erschnien me illogical that the module is functioning when it is upside down on a 14Watt LED spotlight, but not in direct Mittagsssone. Even with various mobile phones of different companies is purely could not be reached, a shop with natural light, while everything worked out perfectly on the radiator.
But since then the specification unfortunately does not correspond, I can not recommend more money in hand to take and use solar panels in higher price categories.
