This year i will be adding a 2 2X20 solar panels to my pool, as well as redoing the whole equipment pad. My origanal plan was to have a 3 way valve to direct the flow either direct to return line, or loop through panels first.
I just received the panels and while reading the instructions it says they work best at 1-4gpm flow. So now my question is can i stick with origanal plan and divert all flow through panels (at best i belive max is 30gpm) or should i just divert a portion of the flow, if its just a portion can i just turn the 3way a little to acheive this? Would a check valve be needed to make the flow accually go through panels?
My origanal plan did not include a check valve, the panels will be rack mounted next to the pool, on the ground.
