Abstract
The utility model provides a photovoltaic assembly with a large light collection area, comprising a framework, a glass plate and a back plate both mounted on the framework, and a plurality of solar cells mounted on the back plate, characterized in that the back plate at gaps between any two adjacent solar cells is provided with a plurality of protruding strips, and the framework is provided with a reflection strip higher than the glass plate. The photovoltaic assembly with a large light collection area enables light to be reflected to the glass plate through arranging the reflection strip on the framework, and is provided with the plurality of protruding strips at the gaps between any two adjacent solar cells, thereby reflecting the light radiated to the top of the framework to the solar cells, and expanding the light collection area to the glass plate and the top surface of the whole framework.
Description
Technical field
The utility model relates to solar energy photovoltaic system, particularly, relates to the photovoltaic module of high daylighting area.
Background technology
Along with the high speed development and the suitability for industrialized production degree of global economy are increasingly high, human increasingly high to energy degree of dependence.But the reserves of fossil energy are limited, and energy problem has seriously restricted the whole world and development of regional economy.The burning of fossil energy has simultaneously brought serious environmental problem.Solar energy has caused multinational attention as the green regenerative resource of cleaning, and has dropped into great amount of manpower and material resources are researched and developed.
Single solar battery sheet can only produce about 0.5V voltage, and its voltage is required far below practical application.In order to satisfy the needs of practical application, utilize tin bar that the solar battery sheet series connection is formed an assembly.Therefore the physical location that connects behind the some solar cells its sealing through lead is called as photovoltaic module, and it has certain anticorrosion, windproof, hail suppression, ability such as rainproof.
Owing to mainly be in order to satisfy the series connection electrical relation; Must reserve certain clearance between the solar battery sheet; When cooperating solar tracking system to use, the incidence angle angle of photovoltaic module light that glass plate receives is 90 degree, therefore; Part light meeting vertical irradiation is to the zone of gap between the adjacent solar battery sheet of backboard, and this part light still can be reflected back toward air and can not arrive on the solar battery sheet; And the light that is radiated at the frame upper edge portion also can be reflected back toward air, causes light utilization low.
The utility model content
To defective of the prior art, the purpose of the utility model provides a kind of photovoltaic module of high daylighting area.
An aspect according to the utility model; A kind of photovoltaic module of high daylighting area is provided; Comprise frame, be installed in glass plate and the backboard on the frame and be installed in the multi-disc solar battery sheet on the backboard; It is characterized in that the backboard of gap is provided with some raised items between the adjacent solar battery sheet, said frame is provided with the reflecting strips that is higher than said glass plate.
Preferably, the cross section of said raised item becomes isosceles triangle.
Preferably, the cross section of the said reflecting strips triangle that meets at right angles.
Preferably, the material of said raised item is an insulating material, and the surface of said raised item is provided with the reflector.
Preferably, said reflector is a metal coating.
Preferably, said reflector is coated with insulating barrier.
Preferably, said raised item and said backboard are an integral body.
Preferably, between solar battery sheet and the frame, solar battery sheet and conflux between the band and conflux between band and the frame any or appoint a plurality of gaps to be provided with some raised items.
The utility model is through being provided with reflecting strips on frame; Light is reflexed to glass plate; And the gap is provided with some raised items between the adjacent solar battery sheet; Thereby the light that shines the frame top is originally reflexed on the solar battery sheet, daylighting area is expanded to the end face of glass plate and whole frame.
Description of drawings
Through reading the detailed description of non-limiting example being done with reference to following accompanying drawing, it is more obvious that the other features, objects and advantages of the utility model will become:
Fig. 1 illustrates the structural representation of photovoltaic module of the prior art;
Fig. 2 illustrates the structural representation according to the photovoltaic module of the high daylighting area of the utility model.
Embodiment
Fig. 2 illustrates the structural representation according to the photovoltaic module of the high daylighting area of the utility model.Particularly; The photovoltaic module of the high daylighting area that provides according to the utility model; Comprise frame 5, be installed in glass plate 1 and the backboard 3 on the frame 5 and be installed in the multi-disc solar battery sheet 2 on the backboard 3; The backboard at 20 places, space is provided with some raised items 10 between the adjacent solar battery sheet, and said frame 5 is provided with the reflecting strips 9 that is higher than said glass plate 1.As shown in Figure 2, the cross section of said raised item 10 becomes isosceles triangle, the cross section of said reflecting strips 9 triangle that meets at right angles.
More particularly, in a preference, the material of said raised item 10 is an insulating material, with said backboard be an integral body, the surface of said raised item 10 is provided with the reflector, wherein, said reflector can be metal coating; Further preferably, said reflector is coated with insulating barrier.
As shown in Figure 1, in the prior art, light is 90 degree by the incidence angle angle of air exposure to said frame 5, so this part light will be reflected back toward in the air.And in the utility model; As shown in Figure 2; Light can shine directly into said solar battery sheet through said glass plate 1 then and perhaps after the reflection of said raised item and glass plate lower surface, shine on the said solar battery sheet by on air exposure to the inclined-plane of said reflecting strips 9.Therefore, the utility model has been realized the utilization to frame end face place light, has improved the utilance of light.
Further; Between solar battery sheet 2 and the frame 5, solar battery sheet 2 and conflux between the band and the band that confluxes is provided with some said convexities with gap between the frame 5, the feasible like this light that shines these gaps shines on the said solar battery sheet after said glass plate reflects once more.
More than the specific embodiment of the utility model is described.It will be appreciated that the utility model is not limited to above-mentioned specific implementations, those skilled in the art can make various distortion or modification within the scope of the claims, and this does not influence the flesh and blood of the utility model.
