The big problem is, it's 15watts in full, direct sunlight. How many hours
of full, direct sunlight do you actually get in the average week? Without
being there to reposition the collector.

Take it to the bank that in the real world, the average output will be more
like 1/4 amp than 1 amp. Then try to figure out how much of that $150 price
tag the end result is really worth.
