Hello funsters. Plan to put solar on the van next year, limited space due to 3 x skylights. Space available is approx. 2 off 1400x850mm and 1 off 1400x650mm (approx because I don't have a ladder long enough to get right up there ) Anyone know an easy way to identify panels by physical dimensions other than trawling websites looking for (often hidden, sometimes non-existent) product specs?
