Solar Panels (Roof Mount)

[jmcst25]

Thanks --

Question -- I believe that the water is going down the return to fast which is causing the vacuum. Wouldn't the vacuum be greater on the return line? I was thinking I needed to move it down on the supply line where their would be more pressure to keep it closed.

I was also considering putting a ball valve on the return line and restricting return flow to minimize vacuum -- will this work -- or is that a bad idea.

I'm just trying to figure this stuff out. (especially - since I'm paying someone to get up on the roof - I want to get it done as short as possible).

BTW -- tphaggerty -- thanks for all your experiences and recommendations.

I am thinking about getting a system, what kind of increase are you seeing, I have a 18 x 36 in ground.


Thanks

It went from 55 to 76 in 2 days - with air temp > 80 in Western PA. I just installed Saturday. My pool is about the same size as yours.

The install was trickier than I originally thought -- (meaning planning the layout and getting all the right parts).

tphaggerty recommended a site call www.powermat.com to gain an understanding of what is involved -- it is really worth the time to read up on them. I bought from solartrope - before gettting information on that site. Powermat does a much better job explaining things. Next time around -- I'd consider paying a little more for a dealer to install -- but there are no dealers in my area that install solar.

I still have to go up and replace some parts that I did not originally order -- ( I did a make shift fix to split the panels to get them working.) I spoke with the dealer today -- he told me the same fix as tphaggerty did to lower the vacuum on the return line. He said the too much air is a common thing.

Best of luck.
