NOVELTY - The solar panel comprises a support layer, a first intermediate layer, a solar cell (4), a second intermediate layer, a front pane (6), a first edge reinforcing layer, a second edge reinforcing layer (7.2), a terminal housing (20), and two collecting conductors (21.1, 21.2). The conductors connect the solar cell to the terminal housing in an electrically conducting manner. The support layer has a projection that projects over a periphery of the front pane. The first edge reinforcing layer is arranged above the projection, and has a cut-out section.    USE - The solar panel is useful in a metal flat roof with a roof pitch of 5-8.8% of a building or a land or water vehicle (all claimed).    ADVANTAGE - The stable and light-weight solar panel exhibits high radiant efficiency and improved performance.    DETAILED DESCRIPTION - The solar panel comprises a support layer, a first intermediate layer, a solar cell (4), a second intermediate layer, a front pane (6), a first edge reinforcing layer, a second edge reinforcing layer (7.2), a terminal housing (20), and two collecting conductors (21.1, 21.2). The conductors connect the solar cell to the terminal housing in an electrically conducting manner. The support layer has a projection that projects over a periphery of the front pane. The first edge reinforcing layer is arranged above the projection, and has a cut-out section. The second edge reinforcing layer is arranged above the first edge reinforcing layer, and has an opening. The collecting conductors are located in the cut-out section and in the opening. The second edge reinforcing layer covers an edge region of the front plate of 1-2 cm, and comprises a drain trough at an outside of the solar panel. The drain trough connects an inner side and an outer side of the second edge reinforcing layer, and has a width of 2-4 mm. The solar cell is a monocrystalline or polycrystalline solar cell, and contains a tandem cell with a crystalline solar cell. The front pane has a thermally tempered or pre-stressed glass having a thickness of 0.9-2.8 mm. The support layer has a first thermal expansion coefficient, and comprises a glass-fiber reinforced plastic with the first thermal expansion coefficient of 7.3-35x 10-6/K. The front pane has a second thermal expansion coefficient. A difference between the first thermal expansion coefficient and the second thermal expansion coefficient is less than or equal to 17%. INDEPENDENT CLAIMS are included for:    (1) a flat roof; and    (2) a process for producing a solar panel.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a solar panel.
