Solar module frames having water drain

1. A frame for a solar module, wherein the frame comprises a plurality of aluminium extruded profiles, which form the sides of the frame and which are connected to one another at the corners thereof, wherein at least one aluminium extruded profile comprises at least one hollow chamber, wherein the frame comprises corner elements, wherein at least one corner element comprises a discharge opening, and the discharge opening is connected to a hollow chamber of at least one adjacent aluminium extruded profile, wherein the hollow chamber is subdivided into two areas by means of at least one inwardly protruding ledge-shaped wall, wherein the first area is larger and is adapted to receive a connector on face side and the second area of the hollow chamber is smaller and serves as a water drainage channel, and the first area and second area are connected to one another over the entire length of the aluminium extruded profile, wherein the aluminium extruded profiles are electrically connected by means of the electrically conductive connectors.

2. The frame according to claim 1 , wherein the connectors can be pressed in a force-fit manner into open face sides of the aluminium extruded profiles.

3. The frame according to claim 1 , wherein connectors comprise ribs which are adapted to be inserted into the face sides, and are adapted to press with their ends against inner wall of the aluminium extruded profiles.

4. The frame according to claim 1 , wherein connectors are extruded profiles cut to length, and comprise aluminium.

5. The frame according to claim 1 , wherein a corner element can be attached to a connector, can be slid on or attached by means of a snap-in or snap-fit connection.

6. The frame according to claim 1 , wherein a corner element comprises two sides which are arranged perpendicular to one another and which are arranged parallel to the face sides of the aluminium extruded profiles and abut on these in assembled state.

7. The frame according to claim 1 , wherein corner element, with its visible outer walls, adjoins in alignment the outer walls of adjacent aluminium extruded profiles.

8. The frame according to claim 1 , wherein the corner element comprises three outer walls adjoining one another forming a corner, and from the corner projecting parts comprising walls that protrude inwardly and emanate from at least two of the outer walls, wherein the corner element can be attached to the connector, by sliding onto at least two ribs of the connector.

9. The frame according to claim 1 , wherein the water drainage channel is connected to an area of the corner element, wherein a lower wall section forms the discharge opening.

10. The frame according to claim 1 , wherein the aluminium extruded profiles comprise a channel, which is open to the interior of the frame, for gripping around the border of solar modules.

11. The frame according to claim 1 , wherein the corner element comprises a front wall which, together with a wall, which is parallel to it, and side walls, forms a reception space for corner of a solar module.

12. The frame according to claim 1 , wherein the corner element is manufactured from aluminium or plastic.

13. The frame according to claim 1 , wherein the connector comprises a recess for screwing in a screw for equipotential bonding, wherein the recess is formed during the extruding process.

14. The frame according to claim 13 , wherein the recess extends in the longitudinal extent of the connector, which is cut to length and formed as an extruded profile, in such a way that the screw axis of the screw for equipotential bonding runs parallel to the normal surface of the frame and securely holds the connector in the vertical direction.
