Abstract

The utility model belongs to the technical field of the photovoltaic new forms of energy and specifically relates to a can cushion sedimentary photovoltaic module of bottom dust is related to. Under the prerequisite that does not change the photovoltaic module waterproof construction, increase abouts 5cm with the length of subassembly apron (1) and backplate (2) on original basis, with waterproof adhesive with crystal silicon cell piece (3) seal up fix lap (1) and backplate (2) middle, follow under crystal silicon cell piece (3) and subassembly lower frame (4) between reserve the about 5cm of a channel width buffer area (5). To lap (1), backplate (2) and crystal silicon cell piece (3) bind as an organic wholely through hot pressing to reach isolated water and atmospheric mesh. Consolidating with aluminum alloy frame (4) at the edge all around at the subassembly, cohering intensity between as banding adhesive reinforcing frame and subassembly with silica gel, the edge of while to the subassembly seals. Dispose the subassembly at last and to the terminal box of outer joint, just so formed can cushion sedimentary photovoltaic module of bottom dust.

Description

A kind of photovoltaic module of available buffer bottom dust deposition
Technical field
This utility model relates to Photovoltaic new energy field, especially relates to the photovoltaic group of a kind of available buffer bottom dust deposition Part.
Background technology
At present, the roof distributed photovoltaic that the solar photovoltaic generation system using BAPV to install on existing building is installed Project development is rapid.Photovoltaic module fills towards Nanan with certain inclination angle and azimuth, in order to receive the most sufficient solar radiation. In the operation management of distributed photovoltaic project, the author finds, owing to distributed photovoltaic installation of project capacity is less, and geographical position Dispersion, it is contemplated that Cost Problems, the manual cleaning of the assembly often frequency that works is relatively low such as the first quarter once.Make at rainwater and gravity Under with, the dust stratification on assembly cover plate can be gradually to congregate.The requirement to prevent internal circuit of photovoltaic module self structure is intake, limit Frame design must be slightly above and nested cover plate plane, thus dust also functions to certain barrier effect.Dust between the O&M cycle The grey dust lane of the widest about 5cm can be formed, due to edge and lower frame distance under crystalline silicon battery plate at cover plate bottom deposit Less about 1cm, the solar radiation that ash dust lane can block crystalline silicon battery plate and cause it to receive reduces.Locally dust stratification can be big Big reduction monoblock unit is so that the generating efficiency of whole photovoltaic group string, and long-time local shades blocks and results even in local temperature Too high, form the hot spot of unrepairable, have a strong impact on the service life of photovoltaic module.
Utility model content
For the problem overcoming dust to deposit at component bottom, it is ensured that between labor cleaning's cycle, photovoltaic module is safe efficient Running, this utility model provides the photovoltaic module of a kind of available buffer bottom dust deposition.
This utility model solve its technical problem be the technical scheme is that do not changing photovoltaic module integral waterproofing knot On the premise of structure, extend component bottom cover plate and the size of backboard so that under crystalline silicon battery plate along and assembly lower frame it Between form the buffer area of one section wide about 5cm and can determine the width of buffer area according to practical situation.Thus constitute one The photovoltaic module of available buffer bottom dust deposition.
The beneficial effects of the utility model are: use the photovoltaic module of this kind of available buffer bottom dust deposition, buffer area Be downwardly inclined installation, dust assemble downwards after can temporary deposition in buffer area, it is to avoid crystalline silicon battery plate is received the sun Radiation can produce impact and the formation of local shadow occlusion.In each O&M cycle, operation maintenance personnel can be to buffer area deposition Dust carries out concentrating cleaning, thus ensure that the safe efficient operation of photovoltaic module.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further illustrated.
Fig. 1 is the photovoltaic module schematic diagram of a kind of available buffer bottom dust deposition, and Fig. 2 is its profile.
Fig. 1, in 2,1. cover plate, 2. backboard, 3. crystalline silicon battery plate, 4. module frame, 5. buffer area.
Detailed description of the invention
Fig. 1, in 2, on the premise of not changing photovoltaic module waterproof construction, by the length of assembly cover plate 1 and backboard 2 former Increase about 5cm on the basis of having, with waterproof adhesive, crystalline silicon battery plate 3 sealing is fixed in the middle of cover plate 1 and backboard 2, at crystalline substance The buffer area 5 of wide about 5cm together with reserving between 3 times edges of body silicon cell and the lower edge of module frame 4.By cover plate 1, backboard 2 It is integrated, to reach the purpose of exclusion of water and air by hot pressing bonding with crystalline silicon battery plate 3.At assembly edge aluminum Alloy frame 4 is reinforced, and strengthens the bond strength between frame and assembly with silica gel as edge sealing adhesive, simultaneously to assembly Edge seal.The rosette that last configuration component externally connects, thus constitutes available buffer bottom dust deposition Photovoltaic module.

Claims (2)

1. available buffer bottom dust deposition a photovoltaic module, have cover plate (1), backboard (2), crystalline silicon battery plate (3) and Module frame (4), it is characterised in that crystalline silicon battery plate (3) is to be sealed in cover plate (1) and backboard (2) with waterproof adhesive Between, photovoltaic module edge is reinforced by module frame (4) and is sealed;On the lower edge of crystalline silicon battery plate (3) and assembly limit There is between the lower edge of frame (4) buffer area (5) that width is 5cm.
