Very few panel vans have the width to take it squarely between the rails. Where it does fit — a coachbuilt motorhome, a horsebox, a shed or a ground frame — 21.5% efficiency means you get more watts from the same area than anything else here.\u003c\/p\u003e\u003ch3\u003eCurrent is the design constraint\u003c\/h3\u003e\u003cp\u003eAt 11.76A operating current, two in parallel is over 23A and the cable needs to be sized for it. Two in series is a much better arrangement at this power level: 68V, half the current, thinner cable — provided the controller's input ceiling allows it.
