Hey all...I've been tinkering for the last few days with solar after managing to pickup most of the essentials here and there over the last few weeks at a pretty minimal cost. I got a nice pump (brand spanking new) for $20 from a garage sale (1/2 horse, so I'm not running my 1 HP main pump just for the solar), and the rest amounted to a DIY project...one which is so embarassing in some regards that I don't even want to post the details at the moment.
I've got probably $80 invested in it all, though...so if the experiment fails, well, I've still got a $200 pump that I paid $20 for and all the other plumbing etc to use with a better system.
I've plumbed the system in so that it's drawing off my skimmer and returns to a dedicated return line which is temporarily just draped across the deck at the moment at the opposite side of the pool.
Can someone crunch my numbers and tell me if my numbers make this worthwhile, or a waste?
Current input temperature of the system (measured electronically right at the input) is 82F.
Current output of the system (measured electronically right at the output pipe) is 86F.
GPH through the system measured at roughly 360 GPH.
This is with the collector in almost direct sun at pretty much the perfect angle.
I've been watching the temp probes for about an hour and those figures have been pretty constant.
So...wise solar guys, school me please.
(Edit: Adjusted in/out readings, figures just changed in the last 10 minutes, solar blanket is also doing it's thing, but both temps went up exactly 1 degree so it's still consistent with the solar collection..)
