The invention relates to a method of producing a solar panel curved in two directions. A problem occurs when solar cells are laminated (attached) to a curved surface (such as the—transparent—roof of a car) that is, at least locally, curved in two directions. Solar cells can bend in one direction (following a cylindrical surface), but to a much smaller degree in two directions. The invention solves this problem by subdividing the multitude of solar cells () in subgroups (L,R,L,R,L,R,L,R), each subgroup associated with an area of the curved surface (). By choosing these subgroups such, that almost no curvature occurs in one direction, the solar cells can be bend in the perpendicular direction. To optimize the efficiency further solar cells are used where anode and cathode are positioned at one side (the side opposite to the photosensitive side), enabling flexible foil to be used for the interconnection of the solar cells in a subgroup.
