    OBJECT OF THE INVENTION
    The present invention relates to a solar tracker consisting of multiple rows of photovoltaic panels, each row comprising a single solar tracking axis, which presents the novelty, in front of solar trackers of this type, of comprising a structural configuration adaptable to Irregular orographic surfaces of the land on which it sits, without additional structures being necessary and without generating additional costs.
    Different types of solar trackers are known in the state of the art, among which are double-axis solar trackers to permanently orient the solar panels perpendicular to the sun and thus obtain maximum energy collection, but that does not compensate for the increase of cost on the obtained yield and also, with the objective of maximizing the double axis follower, the surface to be controlled is usually relatively large, from several tens of square meters to almost 100 m2. This implies that the wind-resistant surface is very large, which forces the structure to be oversized in order to provide it with the necessary resistance that supports not only the force of the wind, but also the turning moments that result from the asymmetries in the distribution of pressures, which also forces an oversize of the actuators to be able to control the positioning of the set.
    Since the surface is usually relatively large, in order to be able to orient it conveniently, the pillars must have a certain height, which implies difficulties in the assembly of each of the followers, in addition to assuming a clear visual impact.
    The arrangement of panels in single-pole structures makes it difficult to apply control algorithms to reduce the impact of shadows cast by nearby structures, which implies a greater separation between followers.



    This distance between followers to avoid shading each other implies less use of the land, in relation to installed power per square meter.
    On the other hand, this type of single-pole double-axis followers mounted on a single pillar, requires in the assembly process an important degree of specialization of both labor and machinery, which implies an additional cost of materials and time, resulting in A clearly higher cost.
    On the other hand, the so-called solar trackers of a single axis with solar tracking to a horizontal axis, which seek to obtain a good energy collection with a simpler assembly, and a decrease in manufacturing, installation and maintenance costs compared to the previous ones, include multiple rows of solar panels arranged in parallel supported on a horizontal structure actuated in rotation to swing the solar panels and orient them towards the sun. These solar followers, in turn, can be subdivided into two large groups. On the one hand there would be the followers of a single actuator for the set of axles, which have an excessively rigid structure and are for e II or very sensitive to the forces transmitted by the wind, aggravating this problem of stiffness by increasing the number and length of rows of plates. This rigidity of the structure and the excessive space occupied by this type of solar trackers, makes it difficult to install it on terrains with irregular surfaces. But in addition, to ensure that this type of solar trackers can withstand the actions of wind and other adverse environmental conditions, concrete foundations, such as shoes, or piles, are usually used, considerably increasing the cost of installing the solar tracker.
    On the other hand, there would be the solar trackers of a single axis with tracking in the East-West direction but with movement caused by several actuators, one for each row of solar panels of the follower. In this case, the different rows of solar panels that make up this solar tracker are not linked together, but each row acts independently through a linear actuator, which causes the axis of the row of solar panels that make up the axis to rotate. Solar Tracker.
    In both cases, to achieve an adaptability to the ground in the event of possible deviations from it in the North-South direction, it is currently achieved by increasing costs by having to increase parts in the follower configuration such as hinges, additional legs, and subjecting the structure to stresses, since the center of gravity is displaced with respect to the center of rotation.
    It is therefore necessary to have a solar tracker with a structural configuration that allows compensating the irregularities of the land in the North-South direction and that attenuates the loads that the structure must bear due to external actions with a minimum increase in cost, this being the object of the present invention. Accordingly, the present invention proposes a single-axis solar tracker with an structural configuration advantageously suitable for settling on uneven surface terrain, and this is achieved thanks to the novel incorporation of an adaptive ball of a high density polyethylene material. In addition to contributing to lower maintenance, it is of great stability since the center of gravity is not deviated from the axis of rotation.
    The advantages offered by the present invention over known solar trackers are the following:
    Perfect adaptability of the solar tracker both to the dimensions of theterrain as to its irregularities.Minimum civil works.Increase in the profitability of projects due to a decrease inthe cost.Fully scalable, from small installations to severalmegawattsMinimum amount of moving parts.Due to its low height (less than 2 meters) it generates a minimum ofenvironmental impact.
    Maintenance is reduced to the revision of the motor-actuator assemblylinear.In the event that the linear motor-actuator assembly is damaged,responsible for the movement of the follower, the system can continueproducing electricity as if it were a fixed structure system.Absence of vertical profiles due to double use of the pieces offastening of the photovoltaic panels to the structure.Totally resizable.
    BACKGROUND OF THE INVENTION
    Although no invention has been found identical to the solar tracker adaptable to irregular lands object of the present invention, we present below found documents that reflect the state of the art related to it.
    Thus, document ES1061033U refers to a solar tracker for photovoltaic panels, in which the panel is rotatable with respect to an axis parallel to the polar axis NS of the earth, comprising a geared motor that imparts a speed of 15 ° / h to the panel, in such a way that the panel follows the sun throughout the day. In comparison with the proposed invention, the rotation is only of a panel, not of an axis acting on a row of solar panels or panels.
    Document ES2253099A 1 proposes a solar tracker of the type that through systems that follow the path of the sun is used to improve the production of photovoltaic panels, capturing the maximum radiation of solar energy for as long as possible, being constituted so that in its upper part the photovoltaic panels are placed in rows arranged separately at different levels and on two slopes, favoring their ventilation, and allowing the expansion of the frame; each panel being supported by two fork-shaped pieces to which it is tied by four clamps, screwed to the panel frame which are in turn welded to a support pipe and spaced apart from each other depending on the width of the panel and the screw tightening, forming, the support pipes with their corresponding forks each of the mentioned rows of solar tracker panels. In this case, the rigidity of the tweezers and forks prevents the settlement of the solar tracker on uneven surface soils as the invention object of the present specification does, through the adaptive ball joint of high density polyethylene that it proposes as a novelty.
    Conclusions: As can be seen from the research carried out, none of the documents found solves the problems raised as the proposed invention does.
    DESCRIPTION OF THE INVENTION
    The solar tracker adaptable to irregular terrain object of the present invention is constituted from a structural configuration advantageously adaptable to the irregular surface lands on which it sits, by incorporating in its perpendicular joints an adaptive ball joint of a high polyethylene material density that in addition to contributing to lower maintenance, is at the same time of great stability.
    Said solar tracker is constituted by multiple rows of independent solar panels, each row being supported by a horizontal structure of a single axis on which it pivots to track the sun, and lacking said structure of additional vertical profiles, since the same system The central clamping of the module confers vertical stability, resulting in less rigid structure and a decrease in costs.
    In each of said axes said solar tracker has a linear rotation actuator that causes the pivoting of all the solar panels of each row. Said actuator is attached to the structure by means of a crank-crank transmission system in which a motor acts as a connecting rod and the crank consists of a piece of galvanized steel coupled to the single axle In order to compensate for the irregularities of the ground where said follower sits solar, the single axis of each row of solar panels is divided into five semi-axes assembled together by means of articulated adaptive ball joints. The whole of the solar tracker is supported on a variable height support legs that are directly driven to the ground or in case of difficulties due to the constitution of the ground, screwed to a ground penetration system, both systems being capable of being regulated in height to also be able to adapt to the soil surface. The photovoltaic modules that make up the solar panels are arranged and retained by means of aluminum sub-profiles, which have height supplements to reach the minimum height required to overcome said adaptive ball joint.
    The adaptive kneecap consists of two key concentric parts: an outer hollow spherical body that houses a second concentric spherical body with the previous one and on which it slides and said body is crossed by the single axis itself. Said adaptive ball joint is executed in a high hardness plastic material such as high density polyethylene.
