A LONG time ago, when I was in college, I worked at the Florida Solar Energy Center testing collector performance. I quickly learned that there is a big difference in the performance of hot water solar collectors. I just went to their site and they have performance ratings on pool solar collectors posted. Looks like most of the pool collectors are about 1000 BTU/Ft2, but there are some that are a lot less. I recommend you check out their site to see if the collector you are considering was tested, and has a rating from the FSEC.
