I want to add 3 more 4 X 12 panels to the other side of my roof. My house faces North / South. The existing 3- 4 X 12 panels are on the east side of the roof with the header running parallel with the peak. How would I run the water flow if I add panels to the other side of the roof? Should I turn the panels and run them left to right rather than up and down? That seams to me to be the easiest way to run the water evenly threw the system. Also I have a tile roof if that makes a difference. I could use all the help I can get. Thanks
