Definitions
- the present invention relates to an automatic method of orienting a solar panel and a device for orienting a solar panel, that is to say an orientation device operating according to such a method.
- the invention also relates to a solar energy conversion system comprising such a device for orienting a solar panel device and a solar panel device.
- Orientation devices can be classified into two categories:
- the so-called active orientation devices that is to say using an external energy, including electrical energy, to allow the system to track the course of the sun. These guidance devices often use stepper motors to move the solar panels.
- the so-called passive orientation devices that is to say not using any external energy source to allow the solar panels to be held and oriented so that they are positioned at least substantially perpendicular to the radius of the sun.
- the energy consumed by an active orientation device is low compared to the amount of energy converted by the solar panels that the orientation device is intended to orient.
- the energy consumed by an active orientation device is no longer negligible compared to the amount of energy converted by the solar panels that the orientation device is intended to guide and in particular, is not negligible compared to the energy savings provided by the orientation device with respect to a fixed solar panel system.
- passive orientation devices are of interest.
- Passive orientation devices are already known.
- a first orientation device two identical cylinders and subjected to the same pressure are arranged on each side of a solar panel and at the same distance from the center of rotation of this solar panel. They are filled with a fluid having a low boiling temperature.
- the device also provides caches arranged judiciously so that if the sun's rays are not perpendicular to the surface of the solar panel, the radiation reaches mainly one of the two cylinders, which causes in the latter the boiling of the fluid and a transfer of fluid from one cylinder to another. It follows that the respective weights of the two cylinders are no longer the same, and that the solar panel tilts accordingly.
- the orientation device does not withstand external elements such as gusts of wind, because its balance around the ideal position is precarious and because the efforts it puts into play are weak vis-à-vis the efforts produced by a gust of wind for example;

- a liquid fills a chamber which is connected to a jack. The expansion of the liquid is used to move the cylinder rod and, as a result, to move the solar panels.
- the orientation of the solar panels is a function of the temperature of the liquid and not necessarily a function of the orientation of the solar rays.
- the chamber is not exposed to the sun's rays and the temperature of the liquid depends only on the temperature of the ambient air. It follows that the sun's rays are not necessarily perpendicular to the solar panels in this first part of the day.

- the solar rays can not have a constant incidence compared to the solar panels during this second part of the day and that the solar rays are not therefore perpendicular to the solar panels.
- the ambient temperature necessarily has an influence on the orientation of the solar panels. Therefore, if, under certain conditions, the sun's rays are perpendicular to the solar panels, under the same conditions, but with a different ambient temperature, the solar rays will not be perpendicular to the solar panels.
