Looks good, but parameters not as described. on midday fully sunny day. i can measure only 21 volt and 0.3-0.4 amps. so its only 8 watt panells. i will test more to see if its gets better results.

Less power output than advertised. They should cost less. The plastic bends and gets deformed if you put it in direct sunlight in hot places like the car dashboard. It wont work on really hot days like 35 deg celcius or more.
