Definitions
- the invention relates to a method of aligning a set of solar modules of a solar tracker.
- a solar tracker is composed of several solar modules forming a set.
- Each solar module has a solar radiation processing element, such as an oltaic photo panel, a mirror, etc., mounted movably on a base of the solar module to be able to follow the movement of the Sun. If the solar module is a one-axis, the solar tracking motion is azimuthal. If the solar module is a two-axis, the solar tracking motion is double, azimuth and zenith. Two adjacent solar modules of this set are connected to each other by means of connection and transmission of a solar tracking motion. These connection and transmission means are generally control rods for connecting and transmitting a movement between two solar modules of a set forming a solar tracker.
- the solar tracker comprises motorization means for performing the solar tracking movement of all the solar modules of the solar tracker.
- the motorization means comprising an electric motor, are located in the center of all the solar modules of the solar track between two adjacent solar modules of this assembly.
- the solar tracking movement comprises, as previously indicated, a so-called azimuthal movement and / or a so-called zenith movement, depending on the type of the solar tracker, one-axis or two-axis.
- each axis comprises a motorization means that can be independent of that of the other axis.
- An object of the invention is to provide a method of aligning a set of solar modules of a solar tracker for aligning each of the solar modules precisely facing the sun using the only drive means per axis and control rods for transmitting the movement to the different solar modules on this axis.
- a method of aligning a set of solar modules of a solar tracker comprising connection means and transmission of a solar tracking movement of a solar module of the set of solar modules to an adjacent solar module of the set of solar modules, the method comprising an iterative loop comprising, for a current iteration, steps of: a) disconnection of adjacent solar modules from a aligned subset of solar modules from a previous iteration;
- the alignment method according to the invention has at least one of the following additional characteristics the method comprises an initialization step prior to any iteration of the iterative loop in which the aligned subset of solar modules comprises only one of the solar modules of the set of solar modules of the solar follower;
- the aligned subset of solar modules comprises means for motorization of solar modules connected to at least one of the solar modules of the aligned subset of solar modules;
- step c) is carried out by the motorization means of solar modules;
- step c) the orientation is performed as a function of an alignment shift between the reference solar module for the current iteration and the solar module belonging to the aligned subset of solar modules and adjacent to the reference solar module for the current iteration;
- the method comprises a preliminary step of determining for each of the solar modules of the set of solar modules of the solar tracker an optimal position with respect to the Sun, the solar modules being connected to each other by the connection and transmission means;
- the alignment offset is determined from the optimal position of the reference solar module for the current iteration and the adjacent solar module belonging to the aligned subset of solar modules.
- FIG. 1 schematically illustrates a solar tracker comprising a set of six solar modules interconnected by control rods and intended to be aligned with the alignment method according to the invention
- FIGS. 2 to 6 are schematic views illustrating successive iterations of an iterative loop of the alignment method according to the invention applied to the alignment of the solar modules of the solar tracker of FIG. 1.
- the solar module 30 is connected to the solar module 40 using a set of control rods 37,74.
- Motorization means 70 of the solar follower 1 are here located between the solar modules 30 and 40, the set of control rods 37 connecting the motorization means 70 to the solar module 30 while the set of control rods 74 connects the motorization means 70 with the solar module 40.
- a single axis is represented by all the control rods 12,23,37,74,45,56 and are motorized by the drive means 70.
- this set of control rods / motorization means is doubled, so as to have a set of control rods / motorization means for each of the axes.
- the first azimuthal axis is controlled by a first set of control rods / motorization means as previously described, and the second zenithal axis is controlled by a second set control rods / motorization means identical to that previously described.
- this is described for a single set of control rods / motorization means, this can be transposed to two sets of control rods / motorization means by performing the steps concerning this set of control rods / means of motorization concomitantly with the two sets.
- this applies mutatis mutandis to a multi-axis follower.
- the different solar modules 10 to 60 are mounted in a position and a random alignment with respect to each other.
- the alignment method according to the invention will determine the optimum position with respect to the sun of each of the solar modules of the set of solar modules of solar tracker 1.
- This preliminary step while the solar modules 10, 20, 30, 40, 50, 60 of the solar tracker 1 are connected two by two by the various control rods 12,23,37,74,45,56, regardless of the relative position of the solar modules 10, 20, 30, 40, 50, 60 at that time.
- several methods exist to achieve this preliminary step.
- a first method consists in that the drive means 70 are actuated so that the first solar module among the six solar modules 10, 20, 30, 40, 50, 60 of the solar tracker 1 is oriented optimally vis-à-vis -vis the sun.
- the motorization means 70 are accelerated or decelerated as appropriate.
- its azimuthal and zenith positions in the context of a two-axis solar tracker are recorded and associated with a survey time, and thus at a corresponding Sun position. Then, iteratively, the previous operations are redone for each of the other five solar modules of the solar tracker.
- a second method is to use a compensation device (not shown) located within each solar module of the solar tracker, compensation device through which the control bar orients the solar module.
- This compensation device which is actuated either manually or automatically, makes it possible to introduce an offset between the control bar actuating the solar module and the actual orientation of the latter. This offset is recorded for each solar module of the solar tracker. From the set of offset data obtained during this step of detecting the optimum position of each of the solar modules with respect to the sun, it is possible to calculate the orientation or alignment offset between two adjacent solar modules. of the set of solar modules 10, 20, 30, 40, 50, 60 of the solar tracker 1.
- the first method is purely manual and consists in detecting the best position of each of the solar modules of a set of solar modules of a solar tracker by means of a visual check on the solar radiation treatment element forming part of the solar module considered. .
- a third method consists in using solar collectors positioned on or in the vicinity of the solar radiation treatment element or by using the solar radiation processing element itself as a sensor. This method is similar to the first purely manual method previously described. The optimum position with respect to the sun of the solar module is given when a maximum power is measured at the output of the sensor or sensors associated with the solar radiation treatment element considered. This method can be semi-automatic by coupling a control system of the drive means 70 to the sensor (s) used for the detection of the position.
- the first step of the iterative loop concerns the disconnection of the aligned subset of solar modules of solar modules adjacent to this subset by removing the control rods connecting these modules. said solar modules adjacent to the aligned subset of solar modules.
- the aligned subset of solar modules comprises only the solar module 40 and the drive means 70, that is to say during the first iteration of the iterative loop of the alignment method according to the invention, the control rods 45 and 37 are removed to disconnect the solar modules adjacent to this aligned subset of solar modules that are the solar modules 50 and 30.
- the solar tracker 1 is in a configuration in which the new aligned subset of modules
- the solar module comprises the solar module 40 and the solar module 50 which are perfectly aligned with one another and connected to each other.
- the solar module 30 is then integrated with a new aligned subset of solar modules comprising the solar modules 30, 40, 50 and 60 as well as the drive means 70.
- the new aligned subset of solar modules has four solar modules, a number that is different from that of six solar modules of solar tracker solar module assembly 1. Therefore, a fifth iteration of the solar module Iterative loop is performed under the same conditions as before.
- the reference module for this fifth iteration is the solar module 20 whose control rods 23 connecting it to the solar module 30 are removed.
- the solar module 30 is aligned with the solar module 20 by means of the motorization means 70, which implies the identical orientation of the solar modules 40, 50 and 60 with respect to this solar module 20.
- connection bars 12 are reinstalled, reconnecting the solar module 10 to the solar module 20 and creating a new aligned subset of solar modules, this time including the six solar modules of the solar module assembly of the solar module.
- solar follower 1 as shown in Figure 6.
- the solar modules of the solar tracker 1 having been perfectly aligned with each other, the alignment method according to the invention ends.
- the order in which the different solar modules have been successively integrated is purely illustrative and can to be different.
- the order may be:
- the alignment and iteration order of the iterative loop of the alignment method according to the invention. invention can be:
