Photovoltaic facility

1. A photovoltaic facility comprising a solar tracker and at least one square or rectangular photovoltaic panel mounted on said solar tracker, the photovoltaic panel comprising two opposite horizontal edges, the solar tracker enabling the inclination of the photovoltaic panel to be varied with respect to the horizontal, so that the two horizontal edges of the photovoltaic panel are always horizontal whatever the inclination of said photovoltaic panel, wherein the photovoltaic facility comprises at least one gutter for recovering rainwater, wherein the gutter comprises a first longitudinal rim and a second longitudinal rim, wherein the gutter is mounted along one of the two horizontal edges of the photovoltaic panel using at least two anchoring devices, to which the gutter is suspended, so that the gutter can oscillate under the action of the weight of the gutter, about a horizontal axis of rotation, so as to remain horizontal, or substantially horizontal, whatever the inclination of said photovoltaic panel, wherein each anchoring device comprises:

a support provided with a horizontal pivot and a fastening device on said photovoltaic panel,

a first suspension cable provided with a first end and a second end, the first end of the first suspension cable being fastened to the first longitudinal rim of the gutter,

a second suspension cable provided with a first end and a second end, the first end of the second suspension cable being fastened to the second longitudinal rim of the gutter,

the second end of the first suspension cable and the second end of the second suspension cable being fastened to the horizontal pivot either directly or by a third suspension cable which connects the horizontal pivot to a connection point of the second end of the first cable and of the second end of the second cable,

and wherein the at least two anchoring devices are mounted on the photovoltaic panel so that the respective pivots of the anchoring devices are coaxial and define said horizontal axis of rotation.

2. The photovoltaic facility according to claim 1 , wherein the fastening device comprises a clamp which enables the horizontal edge of the photovoltaic panel to be clamped.

3. The photovoltaic facility according to claim 1 , wherein the horizontal pivot is a rotary damper pivot.

4. The photovoltaic facility according to claim 1 , wherein the photovoltaic panel comprises two opposite lateral edges, perpendicular to the horizontal edges,

wherein the support has an L-shape with a first arm and a second arm,

wherein the horizontal pivot is fastened to a free end of the first arm and perpendicularly thereto,

and wherein the fastening device is fastened to a free end of the second arm, so that the support is fastened on the photovoltaic panel using the fastening device, so that the second arm extends in a direction which is parallel to the lateral edge of the photovoltaic panel and so that the pivot is horizontal.

5. The photovoltaic facility according to claim 4 , wherein the length of the second arm is such that the horizontal edge of the photovoltaic panel is located above the second longitudinal rim of the gutter when said photovoltaic panel is horizontal.

6. The photovoltaic facility according to claim 1 , wherein the gutter has two ends and wherein the photovoltaic facility comprises two anchoring devices which are fastened respectively to the two ends of the gutter.

7. The photovoltaic facility according to claim 1 , wherein the gutter has a bottom and at least one drain orifice in the bottom, the drain orifice being provided with a drain connector wherein the photovoltaic facility comprises at least one rainwater storage tank and at least one flexible pipe connecting said drain connector of said gutter to the storage tank.

8. The photovoltaic facility according to claim 1 , wherein the gutter is pierced by a plurality of spray holes.

9. The photovoltaic facility according to claim 8 , wherein the spray holes are closed by valves.
