rmanfredini Thetruth is almost that it is a solar panel of 150W/square meter, but it is not one square meter. In the specs is written clearly that: Output: 12V 2000ma so only 24W or 36 at 18V. Considering actual efficiency of solar panels no solar panel of 55cm x 55cm can output 150W Medium solar radiation on the earth is about 1400W/square meter. Best efficiency solar panels have 20% conversion ratio, so about 200-280w / square meter depending on your area. For a solar panel of 1/4 square meter having an output power of 150W would mean to have an efficiency of 40-60%. That is a dream. Do not stop reading at the title, read also the description....

rmanfredini Sorryyou were not cheeted you are unable to read descriptions and you stop only to the title: In the specs is written clearly that: Output: 12V 1200ma so only 14W or 21 at 18V. Considering actual efficiency of solar panels no solar panel of 55cm x 24cm can output 100W. Medium solar radiation on the earth is about 1400W/square meter. Best efficiency solar panels have 20% conversion ratio, so about 200-280w / square meter depending on your area. For a solar panel of 1/8 square meter having an output power of 100W would mean to have an efficiency of 60-80 %. That is a dream. Do not stop reading at the title, next time read also the description (max peak power 30W)

I feel cheeted, i Ordered 2 Panels, Only one set of kabels succers carabiners etc. was includet and the worst is, that the pannel do not produce 100 W peek but only a max output of about 35 W in max bright sunlight. So what Do you plan to do for compensation. To sent 60 % of the Money back would Do or sent waterprof Pannels with a real 100 W peek. I will wait a max of 5 Days for a sufficient answer.
