Abstract

The utility model discloses a novel photovoltaic assembly which includes a bottom plate, a solar cell slice, a panel, and an outer frame which is clamped on the periphery. The panel side of the frame is provided with drainage grooves. Because the panel side of the frame is provided with the drainage grooves, the novel photovoltaic assembly can discharge the rainwater on the panel, and at the same time, take away partial dust, so the manual cleaning maintenance frequency is reduced, the manual cleaning maintenance becomes convenient, the heat spot effect is avoided, the stable operation of the photovoltaic assembly is guaranteed, and the failure rate is reduced.

Description

A kind of novel photovoltaic module

Technical field

The utility model relates to field of solar thermal power generation, especially a kind of photovoltaic module.

Background technology

Because solar panel generally is installed in the open air; Especially solar panel with respect to ground elevation hour; Be easy to pile up dust in panel and outside framework junction, outside framework is tight a little more than encapsulating around panel outer surface and the outside framework in addition, is not easy to rainwater and flows away and take away dust; Dust accretions seriously can block battery sheet light-receiving area, and then causes hot spot effect to damage solar panel.So-called hot spot effect is exactly under certain condition, and the solar module that is blocked in a certain series arm will be taken as load consumption, and other have the energy that solar module produced of illumination, and the solar module that is blocked will generate heat this moment.

For the solar panel operate as normal and avoid hot spot effect must carry out regular artificial clean and maintenance.

Summary of the invention

To the deficiency of prior art, the technical problem that the utility model will solve provides a kind of rainwater and part dust and reduce the novel photovoltaic module of artificial clean and maintenance frequency of can flowing away automatically.

In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of novel photovoltaic module; Comprise base plate, solar battery sheet, panel and cutting ferrule from the bottom up successively in housing all around, said housing is provided with rhone in panel one side.

As the improvement to rhone, said rhone is to comprise the bottom and the perforation groove of two side, and the upper surface of the flanging band of the said panel of casing pressure is concordant on said bottom and the said housing.

As the improvement of a kind of novel photovoltaic module of the utility model, said housing comprises two long margin frames and two the minor face frames that are oppositely arranged respectively, and said rhone is located on the said long margin frame.

As the further improvement of a kind of novel photovoltaic module of the utility model, said rhone is located at the end of said long margin frame, and a said bottom and a sidewall are located on the long margin frame, and another sidewall is the end face that docks with said long margin frame on the said minor face frame.

As the further improvement of a kind of novel photovoltaic module of the utility model, the said sidewall of being located at long margin frame is a curved wall.

As the further improvement of a kind of novel photovoltaic module of the utility model, said rhone is located at the both ends of a said long margin frame.

As the further improvement of a kind of novel photovoltaic module of the utility model, said rhone is located at the both ends of two said long margin frames respectively.

With respect to prior art, the beneficial effect of the utility model is: through the rhone that housing is provided with in panel one side, automatically the rainwater on the photovoltaic module panel is drained and take away the part dust simultaneously; Reduce artificial clean and maintenance frequency and convenient artificial clean and maintenance; Avoid hot spot effect, improved the stable operation of photovoltaic module, reduced failure rate.

Fig. 2 is the side structure sketch map of a kind of novel photovoltaic module of the utility model.

Among the figure, 1 is panel; 2 is housing;

3 is rhone; 21 is long margin frame;

22 is the minor face frame; 23 are the flanging band;

31 is the bottom; 32 is the first side wall;

33 is second sidewall.

Embodiment

Further specify the embodiment of the utility model below in conjunction with accompanying drawing.

See also shown in Fig. 1 and Fig. 2; The utility model photovoltaic module comprises base plate (not shown), solar battery sheet (not shown), panel 1 and cutting ferrule from top to bottom successively in housing 2 all around, and said housing 2 is provided with rhone 3 in panel 1 one sides.

Said rhone 3 can be one-body molded with housing 2, also can machine-shaping on housing.

The rhone 3 that a kind of novel photovoltaic module of the utility model is provided with in panel 1 one sides through housing 2 is drained the rainwater on the photovoltaic module panel automatically and is taken away the part dust simultaneously; Reduce artificial clean and maintenance frequency and convenient artificial clean and maintenance; Avoid hot spot effect, improved the stable operation of photovoltaic module, reduced failure rate.

Said rhone 3 is the perforation groove that comprises bottom 31 and two side (the first side wall 32, second sidewall 33); The upper surface of the flanging band 23 of the said panel 1 of casing pressure is concordant on said bottom 31 and the said housing 2, guarantees that rainwater and dust can not infilter photovoltaic module when draining smoothly the inside damages solar panel.

Further, said housing 2 comprises two long margin frames 21 and two the minor face frames 22 that are oppositely arranged respectively, and said rhone 3 is located on the said long margin frame 21.Photovoltaic module is generally with the placement that is close to the ground of one of them long margin frame, and rhone 3 is provided with on the frame 21 on the scene, is more conducive to rainwater and dust is discharged swimmingly.

More preferably, said rhone 3 is located at the end of said long margin frame 2, and said bottom 31 is located on the long margin frame with the first side wall 32, and second sidewall 33 is the end face that docks with said long margin frame on the said minor face frame 22.Make things convenient for the rhone moulding and be beneficial to rainwater and discharge along the bight of photovoltaic module.

More preferably, the said the first side wall 32 of being located at long margin frame 21 is curved wall, avoids machining stress to concentrate when guaranteeing long margin frame intensity.

More preferably, said rhone is located at the both ends of a said long margin frame, accelerates the discharge of rainwater and dust.

More preferably, said rhone is located at the both ends of two said long margin frames respectively, all guarantees rainwater and the smooth and easy discharge of dust no matter the photovoltaic module long margin frame is installed with pasting ground installation or the subsides of minor face frame.

The above disclosed preferred embodiment that is merely the utility model can not limit the interest field of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
