I have purchased 2 of the 4x20 above ground panels and I am getting ready to install them, I have a question. I read everywhere that it is best to run them parallel, however they have the disc in them that makes you have to run them in series. I sent a quetion in to sungrabber about removing the disc and they said if I did it would void the warranty. Has anybody removed the disk? Would you be more concerned with plumbing them for efficiency or would you be more concerned with the warranty? If you did remove the disc what is the best way to acomplish this?
