Ok so i purchased a sunheater brand solar array. The instructions show a horizontal install. Would it be more efficient to install the panels vertically?

Ok, sorry, the original post made no mention of a roof install. Then I agree, there will be little difference in efficiency.FamilyGuy said:*clarification by vertical or horizontal i refer to accross the roof from side to side or down the roof from bottom to top*
