    The invention relates to a system for combining agricultural activities with the generation of solar energy.
    The environment is changing and in particular the temperature will rise. The consumption of fossil fuels contributes to both environmental pollution and the rise in temperature. To counter this as much as possible, an increasing shift is being made to generating energy in other ways, and in particular by using solar panels to generate solar energy. Solar parks with large numbers of solar panels are increasingly being built and planned. The disadvantage of solar parks is that the surfaces covered by solar panels are often only suitable for the generation of solar energy. The land on which the solar parks are built should be relatively cheap, which means that the solar parks should either be placed on otherwise relatively useless land, such as desert areas, or that land previously used for agricultural purposes should be sacrificed to it.
    “Relatively useless soil” can certainly be useful, for example because it concerns a specific nature area with specific flora and fauna or because it is useful for recreational purposes. Such "useless" land is normally far from inhabited areas, so maintenance of the solar park and / or transport of the generated solar energy can be costly.
    An alternative is to place the solar park relatively close to inhabited areas, but this often means that scarce agricultural land close to inhabited areas must be withdrawn from food production. If one wants to switch to more production of vegetable products in particular with shorter supply lines to the consumer, this is a negative development.
    Installations are known which attempt to meet these drawbacks. For example, it is known to keep animals, such as chickens, under solar panels. However, the soil under the solar panels becomes unusable over time.
    Dual-use solar parks are known under the name “Agri-Voltaic systems”: “Agri” for “agriculture” and “Voltaic” for the generation of solar energy.
    Such an installation is known from, for example
    Indian Farming 68 (01): 20-23; January 2018; Agri-voltaic system: crop production and photovoltaic-based electricity generation from a single land unit by P. Santral, RK Singh2, HM Meena, R. N Kum, describing an installation that consists of rows of angled solar panels standing on poles and are oriented obliquely to the sun, with crops that require a relatively large amount of water being grown between the rows of solar panels. This concerns agriculture in a semi-arid area and the solar panels are used to collect rainwater. Under the solar panels, crops can be grown that thrive in dry conditions.
    Another installation is known from, among other things, the Sun-Agri project, in which an installation on poles on which solar panels have been installed, at a few meters above agricultural land. The position of the solar panels in relation to the incident sun can be changed to control the amount of sunlight that falls on the plants. The poles are so high that agricultural implements can drive under them.
    This is a complicated system that can easily be damaged in the event of a storm, a thunderstorm or an agricultural vehicle colliding with a pole.
    It is an object of the invention to provide a simple and robust system for combining agricultural activities and solar energy generation.
    To this end, the system comprises mobile carriers for solar panels, movable along, on or over rails, the distance between the rails being preferably more than 4 meters, which carriers comprise a roof construction, the ridge of the roof construction being between 1 and 2 meters. above the ground, the side edges of the roof construction are between 5 and 50 cm above the ground, and on either side of the ridge a number of rows of solar panels are placed on the roofs, preferably the transparency of the solar panels varies from row to row , preferably increases from the side edges to the ridge and the system includes fixed collection means for collecting solar energy generated by the solar panels and means for connecting the mobile carriers to the collection means.
    In use, the mobile carriers can easily be moved over the rails.
    The distance between the rails is preferably so great that agricultural vehicles can work the soil. The roof construction can be placed with the ridge facing south. The sun then moves over the solar panels during the day. A variation of the transparency of the solar panels from row to row creates a variation of the light intensity on the ground. This makes it possible to grow different crops, or the same crop but at different stages of development, next to each other under the carrier. Preferably, the transparency of the solar panels increases from the side edges to the ridge. The light intensity under the roof construction is then highest below the ridge, plants will grow fastest where there is the most room for growth.
    Harvesting products can be done simply by driving away the mobile carriers. During the period when there is little or no sunlight, the mobile carriers can be taken to a storage facility, which greatly reduces the risk of damage from winter storms. Due to the relatively low ridge height, the visual interference with the view is minimal. The hood construction is a simple and robust construction, well resistant to storms and storms and very stable. Moving the mobile carriers can be done manually by means of pushing, as well as pulled by a vehicle or with the aid of an integrated motor.
    Preferably, the distance between the rails is less than 14 meters. With a greater distance, the weight of the construction and / or the ridge height becomes too great. More preferably, the distance is less than 10 meters.
    The ridge height is preferably 1 to 2 meters. The sides are preferably between 5 and 50 cm above the ground. Too low to the ground creates the risk that the edges will collide with stones when the carrier is moved. This clearance is therefore preferably at least 5 cm. More preferably, the sides are at least 10 cm above the ground. If the edges are too high above the ground and the construction should be done heavier. The distance from the edge to the ground is therefore preferably less than 50 cm.
    The ridge height is preferably less than 1.80 meters.
    There may be 3 or 4 rows of solar panels on either side of the ridge.
    Preferably, the support includes a sprinkler installation for spraying the crops under the hood structure.
    These and further aspects of the invention are described and illustrated below with reference to the drawing:
    In the drawing: Figure 1 shows an exemplary embodiment of a carrier on rails for a system according to the invention. Figure 2 a further embodiment of a system according to the invention, Figure 3 a further embodiment of a system according to the invention. Figure 4 a further embodiment of a system according to the invention, Figures 5a and 5b a further embodiment of a system according to the invention, Figure 6 a further embodiment of the system according to the invention, Figures 7 to 9 embodiments with more solar panels per row Figures 10 to 12 further embodiments of a system according to the invention. Figures 13 and 14 show a further example of the invention.
    The figures are not drawn to scale, identical parts are generally indicated with the same reference numerals. Figure 1 shows a mobile carrier 1 for solar panels 2, movable along, on or over rails 3. The distance (d) between the rails is preferably between 4 and 14 meters. The distance is preferably more than 4 meters so that the soil can be worked with agricultural vehicles. The distance is preferably less than 14 meters. The carrier 1 contains a hood structure 4. The ridge 5 of the hood construction 4 is spaced a distance h1 between | and 2 is above the ground. The side edges 6 of the roof construction 4 are located between 5 and 50 cm above the ground. On either side of the ridge 4, a number of rows of solar panels 2 are placed on the roofs, whereby the transparency of the solar panels increases from the side edges to the ridge. Preferably, when using 3 solar panels, the transparency from the edge to the ridge 1 is NON-transmissive (transparency less than 5%) -row 2 20-25% transmissive, row 3 40-45% light transmission. Figure 2 shows an embodiment of a system according to the invention. Herein, collection means 7 are shown for collecting solar energy generated by the solar panels, in this case piles 7. The collection means 7 can also be integrated in the rails or attached to the rails. Also shown are connecting means 8 for connecting the solar panels to the collection means for supplying the generated energy. The collection means can supply the generated energy to, for example, the electricity network or to a storage medium. A crop 9 is also shown in this figure 2.
    Figure 3 shows a further embodiment of or before the invention. Means are provided for lifting the solar panels, in this case the middle solar panels on one side, so that an air gap is created between solar panels through which warm air can escape. This can influence the microclimate under the roof construction.
    Figure 4 shows an exemplary embodiment in which the carrier is provided with a spraying installation 11. In the system, all carriers can be provided with a spraying installation or a part of the carriers. The sprinkler installation can be supplied with energy from the solar panels.
    Figures 5a and 5b show an embodiment in which the carrier is provided with a fourth row of solar panels 2a protruding on one side over the ridge or above the ridge. The protruding panel in the fourth row can be mounted on both the left and right, depending on, for example, position in relation to the sun or the most common wind direction. Preferably, this row has the same or a higher transparency than the third row of solar panels.
    Figure 6 shows an embodiment with 4 rows of solar panels on either side of the ridge.
    In summary, the invention can be described as follows: A system for combining agricultural activities with the generation of solar energy comprises mobile carriers (1) for solar panels (2), movable along, on or over rails (3), whereby the distance (d) located between the rails is preferably more than 4 meters, which supports contain a roof construction (4), the ridge (5) of the roof construction being between 1 and 2 meters above the ground, the side edges (6) of the roof construction are located between 5 and 50 cm above the ground, and on either side of the ridge a number of rows of solar panels are placed on the roofs, whereby the transparency of the solar panels preferably shows a variation. For example and preferably the transparency of the solar panels increases from the side edges to the ridge and the system includes fixed collection means (7) for collecting solar energy generated by the solar panels and means (8) for connecting the mobile carriers ( 1) with the collection means (7). In the context of the invention, “variation” is understood to mean not only a non-monotonically increasing transparency from the ground to the ridge, but also, for example, an alternation in the transparency whereby the solar panels placed closest to the ground have a lower transparency than the row above, the row above it has the same transparency as the second row, and the top row has a lower transparency than the second row.
    It will be clear that many variations are possible within the scope of the invention and that the invention is not limited to the examples given above. In the figures, the carriers are for instance provided with solar panels with a length more or less equal to the length of the carrier. This cannot be construed as a limitation. In the figures, each row contains a panel. A row can contain more than 1, for example 2 or more, for example 6-8 panels. Preferably, each row contains 4 or more solar panels. Figures 7 to 9 show such embodiments. The number of rows can be 3, 4, 5 or higher.
    The frame can for instance be movable automatically by means of an electric motor. This can be especially useful for long systems. Figures 10 and 11 show systems arranged at different locations. This can be advantageously used for plants such as potatoes. These need sunlight and cannot grow completely in the dark. To solve this, an electric motor is preferably added which moves the frame slowly during the day to give the plants, for example, 3 hours of shade per day and sunlight for the rest of the day. Preferably a very long frame is then used, as can be seen in figures 10 and 11. In this embodiment, use is made of a long system frame, for example 12 to 24 meters in length, and for example 8 to 14 meters in width, which slowly moves over field moves as shown schematically in Figures 10 and 11.
    Preferably, the height relative to the rails of the panels is adjustable, as can be seen in figure 12. To this end, in this preferred embodiment, the system is provided with means 12 for adjusting the height of the panels relative to the rails. This can be done with the aid of an electric motor as shown in figure 12. In this way the amount of draft can be regulated, so that the soil of the plants can be heated or cooled depending on the crop that is under the panels. In this way it is also possible to raise the panels further as the plants themselves grow and become taller. These panels can then be moved with the growth of the plants. This is especially useful for taller crops, and the frame can be adjusted accordingly. The system can be provided with one or more sensors and a control to raise or lower the panels based on the deflection of the sensor or sensors. The sensor can for instance be a temperature sensor in which the height is set as a function of the temperature, the sensor can also measure the height of the plants and automatically adjust the height of the panels as the plants grow larger. Other sensors such as a brightness sensor or a humidity sensor can also be used. The deflection of the sensors can alternatively or also be used to control the movement of the system over the rails, for example the speed at which the system moves over the rails.
    In the embodiments described above, the transparency of the solar panels on the frame varies. In other embodiments, use is made of non-translucent panels.
    This can be used on fallow land and / or for some crops that require little or no light (e.g. white asparagus), for such crops the black, i.e. no or hardly any light-transmitting panels can then be applied. This embodiment is for use on fallow land and for crops that need to be protected by blocking sunlight.
    A further example of a system according to the invention is shown in figures 13 and 14. In this example, the system comprises posts 13 on which rails 3 are arranged. The roof construction contains wheels that can run in the rails 3, an example of this is shown in figure 14.
    In this example, the rail has a slot on the side in which the wheels of the roof structure roll. It is noted that in this example a system can also be used in which the piles 13 contain rollers and the roof construction rails. This is nothing but the mechanical reversal of the rails-plus-wheels system of the system shown in figure
    14. In that case the roof construction comprises the rails over or along which the roof construction can be moved. The wheels or rollers are then located on or on the posts. In this example, the side edges can be higher than 50 cm, for example between 50 and 100 cm above the ground. The invention also relates to a carrier evidently for use in a system according to the invention.
    The invention also relates to the use of the system according to the invention for growing an agricultural product and generating solar energy.
    The invention also relates, inter alia, to the use of the opaque panel system for growing asparagus and generating solar energy.
