Ive been living a nightmare solar install that has lasted 2 years.
The current setup....
Distance from pump to panel is probably 100 linear feet and 50 Feet of head (3rd story roof).
Pump is making a very loud noise and suspect the bearings are going. Basically can't sit outside with the pump on. The pump is 3/4 hp which I suspect is underpowered but water does make it through the loop.
The main issue is that the solar panels don't drain down. So the water super heats and is impacting the pipe. My controller is goldline.
I saw on the pentair controller user guide that the recommend a drain on the feed side after the diverter specifically for metal arrays but can't see why a PVC array wouldn't benefit but I'm not sure the goldline computer can control that. They also put their vacuum break at the top of the array, mine is about 10 feet up the feed side. Lastly the pentair 3way diverter has a built in check valve which is a great idea, not sure if I can use that valve within my system and with my goldline actuator.
Thoughts, ideas?
