Description
Technical field
The present invention relates to the automated process of solar panel break-in and the deviator of solar panel, the deviator that promptly moves according to the method.The invention still further relates to solar-energy conversion systems, it has this deviator and the solar cell panel assembly of solar cell panel assembly.
Background technology
Energy requirement in the world constantly increases, and one of purpose in recent years is to seek the energy of reliable environmental protection.One of first step is to make such system: it can or convert solar energy to electricity through the photovoltaic solar cell plate, perhaps converts solar energy to heat through solar heat-collection plate.But the installation of this system still cost is high, and In the view of the consumer, productivity is considered to too low sometimes.
According to research, according to the technology of using, this system of traceable sun stands the gain aspect the average productivity ratio between 15% to 30%.For making the system can the sun-tracing stroke, for said system sets deviator or " tracker " device, it be used to make solar panel with position of sun break-in automatically.
Deviator can be classified as two types:
-so-called active deviator, promptly it uses especially electric energy of external energy, in order to can make the system tracks sun.Said deviator often uses stepping motor, so that solar panel moves.
-so-called passive deviator, promptly it does not use any extra power, in order to allow the maintenance solar panel and to make the solar panel break-in, makes solar panel be basically perpendicular to sunray at least and positions.
For mid power and powerful equipment, the energy that the relative deviator of the energy that active deviator consumed is used to make the solar panel of its break-in to change is lower.On the contrary; For low-power equipment; The energy that the energy that active deviator consumed is used to make the solar panel of its break-in to change with respect to deviator; No longer being insignificant, particularly, is not insignificant with respect to deviator with fixed solar cell panel system compares the energy gain that is brought.Under this background, the deviator of passive type has certain superiority.
Known different passive deviator.
In first kind of deviator, two cylinder bodies identical, that bear uniform pressure are arranged on each side of a solar panel, and with the center of rotation of this solar panel at a distance of identical distance.Said cylinder body is filled with to have the fluid of low boiling temperature.Said device also disposes shade in addition; If said shade reasonably is arranged to the surface that sunray is not orthogonal to solar panel; Most of one of two cylinder bodies that arrive of radiation then, this causes in this cylinder body fluid boiling and makes fluid be sent to another cylinder body from a cylinder body.Thus, two cylinder bodies weight separately no longer is identical, solar panel thereby inclination.Although this deviator have some superiority (especially, the performance gain of the solar panel suitable with the performance gain that obtains with active deviator, simple structure with thereby low-cost), it has some maybe very serious defective:
-deviator can not tolerate external factor such as fitful wind because its around balance of ideal position be unsettled and because the active force of its tolerance relatively for example the active force that produces of fitful wind is lower;
-exist to occur around the danger of the phenomenon of ideal position swing: in fact because inertia, solar panel change towards stage the time; Deviator can be crossed ideal position; Then, proofread and correct by counter steering this offside, but can be again surpass desirable towards.Cause dancing thus around ideal position.
Also known a kind of passive deviator from document US 2005/284467, it is used for according to the position of the sun solar panel being turned to.In this deviator, the liquid-filled chamber that is connected in working cylinder.Utilize expansion of liquids, so that the bar of working cylinder moves and thereby solar panel is moved.Therefore, in this deviator, solar panel towards the temperature that depends on liquid, and must not depend on sunray towards.Particularly, in the morning in, said chamber is not shone by sunray, the temperature of liquid only changes with the temperature of surrounding air.Therefore, in the morning, sunray is not necessarily perpendicular to solar panel.Equally, in the morning, said chamber receives the sunray irradiation gradually, thereby said chamber is between the lights than shone by sunray.Therefore, in the morning, sunray can not have constant incidence angle with respect to solar panel, sunray thereby during all the morning not perpendicular to solar panel.In addition, environment temperature must influence solar panel towards.Therefore, if sunray is perpendicular to solar panel under certain conditions, so, under these identical conditions, but with the different environment temperature, sunray can be perpendicular to solar panel.In addition, when device cloud cluster through the time when being left the sun by screening fully, it returns to the position of only being confirmed by environment temperature, this position maybe be from just very far away through preceding position occupied at cloud cluster.
