It's easy to say add another panel but for some of us it isn't quite that simple.
My roof is maxed out without racking to avoid obstacles with the fourth panel. I wouldn't get much out of a fourth panel except for a hot controller as it would be over paneling most of the time. So after racking the panels and replacing the controller, I'd need to find a match to my high voltage panels or risk confusing the controller. Were I not able to find a match, I'd have to buy a new set. Might as well upgrade to the next size up since I racked them, right.
So after a small fortune and a lot of effort, I could go from 750w to over 1700w and avoid tilting. :)
