Description

Solar tracker for equipment guidance solar energy production.

Object of the invention

The present invention, as its own title indicates refers to a solar tracker that has its application in the orientation of a panel of photovoltaic panels, ensuring that make a lateral and inclination turn so that said panel is perpendicular to the sun during the day, regardless of time of day and day of the year in question.

Background of the invention

Current energy production equipment solar, which mount photovoltaic panels on a panel whose maximum energy collection occurs when perpendicular to the solar rays, move in two axes, one of vertical rotation and another that varies its angular position to achieve optimal orientation regardless of the season of the year in which we let's find, since it is well known that the sun not only modifies its height depending on the time of day but it also does seasonally In document ES-1050814 describes a solar tracker that presents a platform or lane circular and a mechanism to vary the angle of each of the plates located in a panel. For its part the document ES-1044310 describes a two-axis follower, the rotation is also done by rotating the panel support post around a circular lane and angular variation by means of a hinge through which the panel is fixed to the post. In both cases the means that control these movements are not controlled by any photosensor device, thereby they only work by approximation and logically unless modify the sequence manually there will be sensitive differences after a few months of operation.

To solve this problem they have devised optical sensors, such as the one described in the document ES-PO484740, which includes as elements of aiming, acting on each of the two existing axes, solar cells positioned in pairs inside and in the outside of a cavity giving each of these sensors a signal of aiming error. The document ES-P488887 also describes its similar system since it places four sensors in two perpendicular diameters of the flat bottom of a cylinder hole.

Description of the invention

The follower object of the present invention assemble two axes of rotation on a large mono-pole height, whose movement is done by two independent moto-reducers, controlled by a sensor located on the panel itself.

The control electronics include a micro controller that allows to force orientations in position of verticality, to clean it or to prevent snow accumulation on the panel, horizontally to protect it from acts vandal or strong side wind. This micro controller includes an operating algorithm that at dusk guides the eastbound panel waiting for the morning setting the position on based on the conditions of the previous days.

Said micro-controller electronic determines the position you must have at all times to be placed perpendicular to the sun through a sensor, located on the panel, formed by three detectors sensitive to the solar radiation, separated by two partitions that form a "T" with bright faces, all protected inside a tube of crystal, determining with the two sensors separated by the frame from the "T" side orientation or from which side the light comes and with the one behind the previous two the degree of inclination, so that they all receive equal radiation intensity when perpendicular to the sun.

The solar panel also has a anemometer with whose indications the micro-controller, if speeds are exceeded  Presets orient the profile panel to the wind direction or puts it horizontal.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, with character Illustrative and not limiting, the following has been represented:

Figure 1 shows an elevation view back of a panel provided with the follower object of this model.

Figure 2 shows a profile view of the front panel

Figure 3 represents a cross section of the base sensor of the operation of this tracker.

Preferred Embodiment of the Invention

As can be seen in the figures referenced the solar tracker for guidance of equipment solar energy production object of this model comprises a single high-rise post (2), on which a panel of photovoltaic panels (1); subsequently presents two axes of rotation that move by means of motor-reducers (3-4) that independently control the angle that the panel (1) forms laterally and the inclination of the same, commanded by a micro-controller electronic, which determines the position you should have in everything time to stand perpendicular to the sun using a sensor (5), located on the panel (1).

Said sensor (5) is formed by three detectors (6-7-8) sensitive to solar radiation, separated by two partitions (9-10) that form a "T" with bright faces, all protected Inside a glass tube. The two side sensors (6-7) determine the lateral orientation from which the light comes, while the sensor (8) located behind the two previous ones allow to determine the degree of inclination, of so that when the panel (1) is perpendicular to the sun all of them They receive radiations of equal intensity.

The solar panel (1) also has a anemometer with whose indications the micro-controller, if speeds are exceeded  Presets orient the profile panel to the wind direction or puts it horizontal. In the same way said micro-controller allows forcing positions of the fully vertical panel, to clean it or to prevent accumulation of snow on the panel and horizontal, to protect it from acts vandal or strong side wind. This micro-controller includes an algorithm of operation that at dusk orients the panel to the east in morning wait setting position based on conditions from the previous days.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not involve an alteration of the essential features of the invention claimed in continuation:
