Hi all. Need some help see what you think.
Ok, i've set up some solar panels to heat pool water, through water polypropilene collectors, in two rows because of roof shape. Water comes out at 32ºc wich is fine, but the fact is I have no idea what pressure I am working at and if all panels are being efficiently used.
I was considering placing two valves and pressure gouges at the exits of each set of panels (A and B), so that I can control more what is happening.
Any thoughts ??

I would put balancing valves on the outlets and fiddle with them. generally, slowing the flow is going to get you hotter outlet temp but with diminishing returns the slower you go. also, watch the amp draw on the pump as you restrict the water flow so it doesnt get too high
Thnx. That's the idea. The gauges would just be extras to know exact pressures.

Why is the bottom row getting hotter than the top row?

As a pool guy, I think running a heater during a summer day is a horrible idea. You are just going to waste chemicals and cause algae. What is your climate and what kind of temperatures do you experience during the day?

Pool guy not trying to make customers waste money on unnecessary chemicals and tat.

No reason really.. I just used photoshop and it came out that way. Technically they should both be identical unless working at different water pressures.

I live in the mountanous region so normal pool water temperature during summer is around 23ºc (= 73), which is ok for dinving and swimming a bit, but actually too cold for kids to stay in and play.
For this, you need to bring temperature up at least to 28ºc/82F or else they simply don't use the pool. Temperature drop quite a lot dunting the night.
Indeed, bringing temperature up means more chemicals and risks of algae, but it's either that or nothing.
