Description
Technical field
The invention belongs to solar energy photovoltaic system, be particularly useful for two-sided photovoltaic solar system, belong to a kind of photovoltaic auxiliary system that strengthens the double-sided solar battery generating efficiency to strengthen its generating efficiency.
Background technology
Photovoltaic technology is expected to instead main force's energy of traditional energy as a kind of emerging energy technology.At present, its key technical problem that need solve is to reduce cost and improve generating efficiency.To these two the not only independent but also technical problems that are mutually related, scientific and technological circle have provided numerous improvement schemes, wherein for improving the generating efficiency aspect, the transformation efficiency that its scheme of paying close attention to emphatically is to improve solar cell with improve it and receive optical efficiency.Receive optical efficiency for raising; Concentrate on again and pay close attention to two aspects of light-receiving area that receive light rate and increase solar cell that improve unit are; Various double-sided solar batteries; Like HIT solar cell, two-side film membrane solar cell etc., on raising solar cell light-receiving area, have fabulous effect, almost the light-receiving area with solar cell on the unit are is doubled.Yet owing to can not let two faces of photovoltaic module accept the sunlight of vertical irradiation simultaneously, shady face is limited to the contribution of light income.
Receive the light rate to increase its generating efficiency for what improve the solar cell photovoltaic assembly, concentrating solar battery has adopted the way of converging ray, in order to increase the optical efficiency that receives on the unit are.The present technique scheme combines these two kinds of technical thought, designs a kind of auxiliary system that can be applied on the common double-sided solar battery photovoltaic array.
Summary of the invention
Goal of the invention: the present invention is directed to existing double-sided solar battery, receive the not enough problem of light rate, on the basis of existing technology, provide a kind of simple and effective way, can increase substantially the generating efficiency of double-sided solar battery to its shady face.
Technical scheme: the present technique scheme comprises optical system, support system: be provided with the composite type bar shaped lens that are positioned at the photovoltaic module both sides in the said optical system, be used to change the light angle of assembly two side positions; Be provided with the reflecting element that is positioned at the photovoltaic module shady face in the said optical system, be used to receive light that composite type reflection from lens comes and it is reflexed to the shady face of said photovoltaic module.
Wherein said composite type bar shaped lens sensitive surface is convex lens, can receive the incident ray of the wide-angle of trying one's best and make its convergence; Its installation site is a little more than the photovoltaic module plane.
Wherein said composite type bar shaped lens shady face is concavees lens, the converging ray that receives is reflected on the said shady face reflecting element of both sides.
Wherein said composite type bar shaped lens are made up of glass, transparent plastic and transparent polymer material etc.
The wherein said photovoltaic module both sides that place can be both sides up and down, also can be for the left and right sides or be side up and down simultaneously.
One of them preferred version is level crossing or level crossing combination for the reflecting element over against the photovoltaic element shady face.
Wherein another preferred version is a concave mirror for the reflecting element over against the photovoltaic module shady face.
One of them preferred version is that said reflecting element is produced by plated films such as glass or plastics.
Wherein another preferred version is that said reflecting element is made up of with the frame setting fexible film plating reflective film
Wherein said support system is a mechanical support, in order to the design angle and the height of fixing each optical element.
Useful achievement:,, make its shady face will be well below the front to the contribution of energy output because its shady face light income is not enough for double-sided solar battery.With the HIT battery, horizontal positioned, its generating efficiency receives light to improve 10% than single face, and heavily fortified point is directly placed, and its generating efficiency improves 34%.Adopt after the system of present technique scheme; Can be with the sunlight of sensitive surface directive photovoltaic module both sides; Make it to inject the shady face of double-sided solar battery photovoltaic module through changing its light path by the concavees lens disperse function again after the convergence of convex lens earlier, receive optical efficiency thereby improve it through reflecting element.Because reflecting element can adopt the optical element with certain converging action, so the luminous intensity that receives of its shady face can be greater than the front, correspondingly, its generating efficiency also can be higher.
Because the sensitive surface of bar shaped compound lens is convex lens in this programme; Can accept sunlight than polarizers of big angle scope; The sunlight that is parallel to photovoltaic array even also can get into shady face through superrefraction, so effective generating dutation of shady face is better than the front in this programme.
Simultaneously and since the light that the backside reflection element can be returned the shady face reflection of glass surface once more the reflected back shady face be used, this sunken light action can further improve the utilance of light, increases generating efficiency.
