Agreed,
Actual usable current for this size solar panel is actually much less than the 0.2 amps. It cannot supply enough power to run a pump directly but could be used to recharge a small battery during daylight hours. The biggest problem is the 12 volts AC for the pump. I would bet that the pump is likely a 12 volt DC pump with some diodes internal to allow it to be connected to a 12 volt AC lighting system. Of course the only way to tell for sure would be to open the pump and I am not recommending that. Warranties get voided that way. If the pump was a DC pump, then bypassing the diodes would get you a simple solution to part of the problem.
