Detailed description of the invention
This utility model described further below.In the following paragraphs, the different aspect of embodiment is defined in more detail.
The each side so limited can combine with any other a aspect or many aspects, not can be combined.Especially
It is it is considered to be preferred or favourable any feature can one or more with other be considered as preferred or favourable spy
Levy combination.
In description of the present utility model, it is to be understood that term " front ", " back side ", "up" and "down" etc. indicate
Orientation or position relationship be based on orientation shown in the drawings or position relationship, be for only for ease of description this utility model, and
Be not instruction or hint indication device must have specific orientation, with specific azimuth configuration and operation, therefore can not manage
Solve as the restriction to this utility model protection domain.
Coating the self-cleaning coat impact on output to reduce the sensitive surface at photovoltaic module, this utility model provides
A kind of photovoltaic module, the sensitive surface of this photovoltaic module is partially coated with super-hydrophilic coating 1.When running into rainy day, rain is dropped in
Moisture film can be extended to rapidly during the surface of super-hydrophilic coating 1, the dirts such as the dust on photovoltaic module surface be floated, and then is easier to
Washed away by rainwater.
Compared with the mode coating self-cleaning coat in prior art on whole sensitive surface, in this utility model embodiment
Super-hydrophilic coating coated area on sensitive surface has reduced, it is possible to reduce super-hydrophilic coating is to the reflection of sunlight and suction
Receive, thus reduce the power loss of photovoltaic module.Space can also be left, after reducing life-time service for the thermal expansion of super-hydrophilic coating
The probability of coating be full of cracks.The usage amount of coating can also be reduced, thus the production reducing the photovoltaic module with self-cleaning function becomes
This.It addition, embodiment of the present utility model uses super-hydrophilic coating as self-cleaning coat, it is possible to solve to use super-hydrophobic coat meeting
The problem being affected self-cleaning effect by contact angle hysteresis.
In one arranges form, super-hydrophilic coating 1 is applied to banded structure, and banding that is such as continuous or that be interrupted is tied
Structure, the track of every super-hydrophilic coating 1 can also be straight line or curve.And the super-hydrophilic coating 1 of banded structure can coat
In the optional position of sensitive surface, can coat one or more of in band according to the position that practical situation is easier to accumulation at dirt
The super-hydrophilic coating 1 of shape structure.If only one super-hydrophilic coating 1 of coating, then can be located at each position of photovoltaic module sensitive surface
Put, such as, along the edge coating of sensitive surface, be coated in sensitive surface being parallel to edge or mode angled with edge
Region, centre.If coating a plurality of super-hydrophilic coating 1, then can be set to a plurality of super-hydrophilic coating 1 to be parallel to each other or intersect
Form, it is possible to the position flexible combination cleaned as required arranges super-hydrophilic coating 1.
In these arrange form, the edge coating super-hydrophilic coating 1 at the sensitive surface of photovoltaic module is preferred scheme,
Such as it is coated in the A limit of sensitive surface, B limit, C limit or D limit.Can avoid sunlight transmitance is impacted as far as possible, can be by
The impact of output power of photovoltaic module is down to minimum by super-hydrophilic coating 1.It addition, in terms of thermal expansion, if at photovoltaic module
Whole sensitive surface uniformly coat, self-cleaning coat does not has overdose space to surrounding thermal expansion, and long-term work is at the bigger ring of the temperature difference
Border easily causes be full of cracks, and on the edge of sensitive surface, only coats the super-hydrophilic coating 1 of banded structure, due to super-hydrophilic coating
1 area is less, and length-width ratio is relatively big, spatial margin when expanding will be made relatively big, thus reduce the possibility that be full of cracks occurs
Property.
It is highly preferred that super-hydrophilic coating 1 is along the minor face coating of the sensitive surface of photovoltaic module, such as, it is coated in the A of sensitive surface
Limit or C limit.This embodiment is compared with the mode coated on the long limit of sensitive surface, it is possible to further reduce super hydrophilic coating
Usage amount, thus save material, and the area of super-hydrophilic coating 1 can also be reduced further, thus increase super-hydrophilic coating 1
Surplus during raw expansion so that anti-crazing effect is more preferable.
After photovoltaic module is installed at a certain angle in practice, rosette 2 is normally at overhead remote position, liftoff
Nearer position, face is due to affected by gravity, it will usually assemble thicker dust, and compared with higher position, it is more difficult to
Cleaning, thus photovoltaic module away from rosette 2 minor face coat super coat be the form that preferably selects, can be by photovoltaic group
The dirts such as the dust of the adjacent edges that part is the nearest float, and make cleaning more thorough, thus reduce cleaning difficulty.
In another kind arranges form, super-hydrophilic coating 1 is applied to thin grating structure, thin grid at the sensitive surface of photovoltaic module
Shape structure is that a plurality of fine rule is arranged in the way of being parallel to each other or be vertical, the cleaning effect that can reach as required in practice
Distance between each bar grid line is selected.This kind of embodiment can cover area bigger on photovoltaic module sensitive surface, from
And the most whole sensitive surface is cleaned.
In another kind arranges form, at least some of adjacent cell piece along photovoltaic module of super-hydrophilic coating
Adjoiner is arranged.This arranges the power that the existence of self-cleaning coat can be made to affect photovoltaic module as little as possible.
For the various embodiments described above, it is preferable that super-hydrophilic coating 1 can be by spraying or the side smeared by fiber cloth
Formula coats.And, the mode of the coating super-hydrophilic coating 1 that this utility model is given both had gone for general components, i.e. arranged
There is polyvinyl fluoride composite membrane (TPT) backboard and have the photovoltaic module of frame, it is also possible to being applicable to be provided with back-panel glass and boundless
The photovoltaic module of frame.Wherein, solar double-glass assemblies designs for Rimless, it is easier to coating super-hydrophilic coating 1, thus is more suitable for by being coated with
Cover super-hydrophilic coating 1 to reach the effect of clean surfaces, super-hydrophilic coating 1 is coated on sensitive surface minor face lower edge, can try one's best
Avoid the dirts such as dust in the accumulation of photovoltaic module lower limb, during rainy day, fall near solar double-glass assemblies sensitive surface lower limb
Dust is easier to be floated wash away, thus reaches the effect of clean surfaces.
