I am just about finished with my solar panel install. I will post final pics when im doing but I just wanted to make sure this VRV is installed correctly. How long does it take to drain the panels after I shut off? I noticed after a few minutes there was still water in the panels. Im not sure if they were draining or not. Is there a way to tell? After about 10-15 mins I took the black cap off and push down on the valve and water shot out. I assume it takes sometime to drain?
Sorry the pics is sideways!
