Solar Panel plumbing and flow rate

[Slachey]

The pump is a 2 hp single speed unit as I mentioned in my post. My plumbing manifold is in a horizontal "H" configuration. On the upper horizontal leg, the flow is from right to left from the filter. In the middle of the leg is the 3-position diverter valve, and to the left is the plumbing to the panels. On the lower horizontal leg the flow is from left to right from the panels and through a "T" section. To the right of the "T", the flow goes back to the pool. The vertical leg between the diverter valve and "T" is the bypass, allowing flow directly back to the pool. I have the diverter valve adjusted so that there is zero flow going through the vertical leg and 100% flow going to the left towards the panels. Location wise, the pump / filter is located directly next to the pool and I have 50' of flex PVC going to and from the 20' long panels.

I should have asked this before but what is the make/model of the pump?

Also, where are the panels installed roof (1 or 2 story) or ground?

Filter pressure with solar on?

I am at the office, so I don't have the details on the pump, but I believe it is a US Motors 2 HP pump. The panels are installed at ground level on a 30 degree rack that I built.

Thanks for your insight on this!

US motors is the motor not the pump. The pump wet end would be made by someone else (Hayward, Pentair, Jandy, Intex, etc).

I will have to check when I get home. I know it is a Columbia 22" sand filter, but I do not recall the pump name on the motor.

Thanks again.

Mas985,

I confirmed that the pump is a Columbia PMX 2HP single speed pump.

Again, thanks for the help.

That is a very low head AG pump so that explains the low PSI rise. It is probably SPL rated (double up rated) so you may need to redirect all the flow through the panels. But what was the filter pressure with all the flow going through the panels?
