Solar panel installation question

[tphaggerty]

Bought one of those Sungrabbers for my brother in law. It does have the disc. Basically, it turns the 2 x 20 into a 1 X 40, the water goes in the input, goes up HALF the tubing to the other pipe, comes back down the other HALF and exits at the output. If you want to put more than one, it makes sense to bring and input to EACH panel (otherwise, if you go input->output->input->output, you are just creating a HUGE series panel and that is going to restrict your flow and make the panel less effiecient).

What does the disc look like? I could not see anything. If I hold the header up to the light it looks like a straight through tube. Perhaps they sent me the wrong item? In any case the way I have it now I am flowing water down the length of one panel into the far end of the other and back up to the top where I take it off to the pool. IF there is a disc it is not doing anything as the panels are realatively cool the entire length. When I did it as they suggest the first panel stayed hot and the second was cool - so I know that was not good.

heads up, one of our panels had been prepped backwards at the factory (the wrong ends had lables for inlet, outlet - so it was basically upside down) We turned it around and it worked fine.

I bought a couple of those sungrabbers but have not installed them yet. I have a IGP with spill over spa and was not 100% sure how I wanted to plumb it. How did you guys plumb yours?

[NWMNMom]

We have a diverter system and plumbed all of ours so that it runs from diverter to a central pvc that Ys off to simultaneous INs and a simultaneous OUT that runs back to the diverter and return. We have ours mounted on a rack system that stands upright on the north side of our pool as we have no left over southern exposure between the pool and the woods.

take encaps off, look though each header, the one you can look through gets the caps (where the water makes a u turn), the one you can't look through gets the input/output connectors.

If you do connect more than 2 units, it is beneficial to remove the baffles (some units allow for that) in the input/output ends of all, install the input connector there and a cap, install the other cap at the far end, with the output connector, feed into the next etc.

I looked through both ends and can see clear daylight through both ends, so I can only conclude the panels don't have the discs they talked about. Anyway, I just came in from repiping the sytem. I have the two panels next to each other with a flexible connector tying them together at both ends. I am feeding water into one tied header and withdrawing from the tied heater at the other end. Seems to be working quite well this way.
