Definitions
- This disclosure relates to the field of agrivoltaics.
- Agrivoltaics or “Agri-PV” is a field that combines agriculture and photovoltaic electricity production on a common surface. The principle is to install photovoltaic panels on an agricultural production area capable of artificially creating shade and shelter and at the same time producing electricity.
- a first known water distributor is in the form of a pierced gutter.
- the gutter has a concave upper surface forming a channel for the flow of collected rainwater.
- a disadvantage of such a gutter is that it tends to concentrate the collected rainwater along a central line at the bottom of the concave surface. The collected water tends to fall into holes arranged along this central line.
- crops located under the gutter are only irrigated in a restricted area. The concentration of rainwater in this restricted area can result in the formation of a cavity in the ground through erosion. Such erosion is harmful to crops.
- a second known water distributor has a flat surface inclined relative to the ground ending in a rectilinear edge.
- the rainwater collected by the second distributor is conveyed through the flat surface to the free edge.
- rainwater falling from the straight edge can only reach a relatively small straight area. Due to potential surface imperfections or the presence of residual dust on the flat surface, rainwater flowing over the flat surface may tend to concentrate, so that rainwater may only reach a restricted portion of the free edge.
- One aim of the invention is to propose an agrivoltaic system which irrigates crops while limiting soil erosion.
- a distributor for collecting rainwater having previously flowed onto the photovoltaic panel having a free edge and a surface ending with the free edge, the distributor being suitable for being placed in a position of use in which the free edge overhangs a ground, and in which the surface is inclined relative to the ground to convey the collected rainwater to the free edge, in which the distributor defines a plurality of channels on the surface to distribute the water from rain collected towards different portions of the free edge, and in that a projection of the free edge on the ground is non-rectilinear, when the distributor is in the position of use.
- the different channels have the effect of distributing rainwater in a controlled manner over the entire length of the free edge.
- the fact that the projection of the free edge on the ground is non-rectilinear in the position of use has the effect of allowing raindrops falling from the free edge to reach an area of the ground extending in two mutually orthogonal directions whose area is greater than that which would be obtained with a free edge whose projection on the ground is rectilinear. Therefore, the water is distributed evenly on the ground. Crops growing on this soil are therefore better irrigated and the formation of cavities in the soil through erosion is limited.
- the proposed system may also include the following features, taken alone or in combination whenever such a combination makes sense.
- the free edge is zig-zag.
- At least two of the channels have different lengths.
- the channels are straight.
- the channels are parallel.
- the free edge is under the photovoltaic panel in the position of use.
- the system comprising a second photovoltaic panel, and the free edge is located under the second photovoltaic panel in the position of use.
- the distributor comprises a polycarbonate plate, the channels being formed in the plate.
- the surface is flat.
- the surface is inclined at an angle between 5 and 50 degrees relative to the ground in the position of use.
- Figure 1 is a schematic longitudinal sectional view of a system according to one embodiment.
- Figure 3 is a cross-sectional view of the distributor of Figure 2.
- Figure 4 is a partial top view of a distributor surface, according to one embodiment.
- a system 1 comprises a photovoltaic panel 2 and a rainwater distributor 4.
- the photovoltaic panel 2 known in itself, has the function of converting light energy into electrical energy.
- the system comprises a structure (not illustrated) on which the photovoltaic panel 2 is mounted, this structure being suitable for being placed on a ground.
- the photovoltaic panel 2 has a receiving surface 6 for receiving sunlight, the energy of which can be converted into electrical energy.
- the receiving surface 6 is flat, for example rectangular in shape.
- the system 1 is shown in a position of use. In this position of use, the system 1 is placed or fixed on a floor, such that the panel photovoltaic 2 is located at a distance from the ground, with the receiving surface 6 inclined relative to the ground and oriented towards the sky.
- the photovoltaic panel 2 is preferably mobile in rotation relative to the structure, such that the angle of inclination of the receiving surface relative to the ground can vary.
- the photovoltaic panel 2 is fixed relative to the structure (and therefore relative to the ground).
- the receiving surface 6 has a free edge 8.
- the free edge 8 is for example rectilinear when the receiving surface is rectangular. This free edge 8 is an edge of the receiving surface 6 which is closest to the distributor 4 (and to the ground in the position of use of the system). When rainwater flows onto the receiving surface 6, this water is directed by gravity towards the free edge 8, and it is from this free edge 8 that the water falls towards the ground.
- the function of the distributor 4 is to collect the rainwater having previously flowed onto the photovoltaic panel 2, when the system is in the use position, and to distribute it to different areas of the ground.
- distributor 4 When system 1 is in the use position, distributor 4 is arranged between photovoltaic panel 2 and the ground. Furthermore, the distributor is located under the photovoltaic panel 2, so as to be able to irrigate plants which are located under the photovoltaic panel 2.
- the distributor 4 comprises a first wall 10 having a first upper surface 12 and a first lower surface 14 opposite the first lower surface.
- the first upper surface 12 When the system is in the use position, the first upper surface 12 is oriented towards the photovoltaic panel 2, and inclined relative to the ground, while the lower surface 14 faces the ground. Furthermore, in this position, the upstream part is at a higher altitude than the downstream part. In this position, when rainwater flows onto the first upper surface 12, this water is directed by gravity towards the first free edge 16, and it is from this first free edge 16 that the water then falls. below distributor 4 towards the S ground.
- the second wall 18 has a second lower surface 20, and a second upper surface 22 opposite the second lower surface.
- the second wall 18 also has a second free edge 24 connecting the first lower surface 20 to the first upper surface 22.
- the distributor 4 comprises a plurality of partitions 26 connecting the first wall 10 to the second wall 18, so as to divide the flow space into a plurality of separate channels 28. More precisely, each partition 26 extends from the downstream part of the first upper surface 12 to the second lower surface 20.
- Figure 3 shows an exemplary embodiment in which the number of partitions 26 is equal to five, so as to delimit four distinct channels 28. It is understood that this is only an example: the number of channels and of partitions may be different.
- the partitions 26 are parallel. Thus, the average directions of water flow in the different channels 28 are parallel.
- each channel 28 is formed by a portion of the first upper surface 12 extending between two adjacent partitions 26, in the downstream part.
- each channel outlet 28 constitutes a portion of the exit zone of the space, and is delimited by a specific portion of the first free edge 16. In this way, the channels 28 distribute rainwater coming from from the photovoltaic panel 2 towards these different portions of the free edge 16.
- each channel 28 can have a rectangular section (as shown in Figure 3), or even square.
- each channel 28 has a width of 10 millimeters and a height of 10 millimeters.
- the wall 10 and the partitions 26 can constitute different parts of a polycarbonate plate.
- the channels 28 are formed inside this plate.
- the second wall 18 can also be part of this plate.
- the second wall 18 is made of aluminum.
- the free edge 16 is not rectilinear (in particular in the plane of the first upper surface 12). Consequently, the projection of this free edge 16 on the ground is not rectilinear either.
- the free edge 16 comprises points which occupy different positions along an axis parallel to an average direction of water flow on the first upper surface 12.
- Figure 4 shows two dotted arrows showing the trajectory followed by water flowing in a first channel and a second channel, both delimited by the distributor 4.
- the first channel has a first length and ends with a first portion of the free edge 16.
- the second channel shown in right of the first channel in Figure 4, has a second length greater than the first length, and ends with a second portion of the free edge 16 different from the first portion.
- the second portion of the free edge 12 is further downstream than the first portion of the free edge 12.
- At least two of the channels of the distributor 8 have different lengths.
- the free edge 16 has a zig-zag shape, that is to say it comprises convex and concave portions arranged alternately.
- this shape is sawtooth, that is to say that the free edge 16 is made up of rectilinear segments.
- the zig-zag shape could be all or part curved, for example sinusoidal.
- a level line of the upper surface 12 (represented in Figure 4 by a horizontal line), that is to say a line having a constant altitude relative to the ground.
- the level line is a projection of the free edge 8 of the photovoltaic panel 2 on the upper surface 12.
- first drop of water is routed through the first channel (following the dotted arrow on the left in Figure 4), that a second drop of water is routed through the second channel (following the dotted arrow dotted to the right in Figure 4), after these two drops of water have left the level line at the same time.
- the first drop reaches the first portion of the free edge 16 before the second drop of water reaches the second portion of the free edge 16.
- the first drop of water will reach a first area of the ground and the second drop water will reach a second zone of the ground located further than the first zone, if we place our in the direction of flow of the drops.
