It gives About 1W power
Voltage is good for charging mobile phones
It's not 200 mA. Short circuit is 180mA and looks like nominal current is about 150-160 mA. When I charge my phone directly current is 130-150 mA.
When it gets hot (10 minutes on strong sunlight) the current degrades to half - about 100 mA short circuit and 80 mA when charging my GSM.
It's a bit expensive. 3W panel costs about $7-$10 per watt. I found 10W panel for $48 ($4.80 per watt).
It needs good cooling if you are gonna use it whole day.
