Compared to existing technology, the beneficial effects of the present invention is:
(1) solar panel provided by the present invention, changes 5 layers of cumbersome design of traditional solar panels, takes
Brand-new material and design, finished-product volume is little, light-duty small and exquisite, is convenient for carrying, can be as the charger carried with, practicality
By force, there is commercial value well.
(2) solar panel provided by the present invention, tens layer materials are arranged in order according to the order set, various
Material can ideally combine.As the ETFE film of protective layer, it is top protection layer, waterproof, ageing-resistant, it is possible to prevent product from rolling over
Disconnected, and play the effect of optically focused, anti-scratch.Further, between the cell piece of laid out in parallel, EPE positioning strip it is provided with, because
During pressing under air bag, the temperature of EVA film is higher, and now EVA film meeting deliquescing also has certain adhesion, and air bag continues
Continuous lower pressure-volume easily causes the displacement of cell piece, and cell piece can be played positioning action well by EPE positioning strip；Additionally, EPE is fixed
Position bar is white, whole product can be played certain decoration function.Additionally, be additionally provided with substrate layer, substrate layer plays decoration
Effect so that product is elegant in appearance.Furthermore, it being provided with the first supporting layer, material is selected from epoxy plate, and epoxy plate has certain hard
Degree, can play support and act on so that product is difficult to be damaged, fracture above each layer.Meanwhile, the second support it is additionally provided with
Layer, material also has certain hardness selected from TPT, TPT, can provide to product and support further.Finally, using 420D nylon as
Base material, as surface treatment, feel is fine, and product plays decoration protective effect.
(3) solar panel provided by the present invention, solaode chip module have employed the monocrystal silicon of 20 string sheets
Sheet, the open-circuit voltage of assembly itself is 10V, by manostat 10V can be converted into 5V, the effect playing voltage stabilizing of manostat,
Photovoltaic module can be controlled the mobile devices such as mobile phone are effectively charged.
(4) solar panel provided by the present invention, the performance of whole product all can be impacted by the thickness of each layer,
Directly affect the experience effect of product.The thickness of every layer of material, is all to have passed through repeated multiple times experiment proportioning out.As
Really the thickness of material is blocked up, the first cell piece group in parallel and the second cell piece group not foldable, if the thickness of material is the thinnest,
Then folded portion is easy to wrinkling.Oneth EVA film layers is set to an EVA film, and its thickness is 0.35mm, so can
Ensure cohesive, the most do not affect light transmission.And the 2nd EVA film layers, the 3rd EVA film layers, the 4th EVA film layers and the 5th
EVA film layers all includes two EVA films, and the thickness of EVA film is disposed as 0.35mm, it is ensured that cohesive so that each
Layer material associativity is good.
(5) preparation technology of solar panel provided by the present invention, the design parameter of each step, be all through
Repeated tests draws, the molding to product is most important.Such as, pressurization is divided into pressurization for the first time and second time pressurization,
And twice pressurization and lamination are provided with different pressure, pressure mainly have impact on the conjugation of multilayer material, and different pressures
Intensity values must in order, and otherwise product there will be the formation unfavorable condition such as bubble, bad, the air spots of feel.And at lamination
Process, temperature is set as 142 ± 5 DEG C, and temperature is too high, can cause the damage of integral material, and temperature is too low, can cause multilayer material
Conjugation inadequate.

5) lamination, upper chamber pressure is set as 0kPa, and keeps 540 ± 50s, and meanwhile, lower room keeps evacuation state；Lamination
Temperature is set as 142 ± 5 DEG C；
6) under, room continues to keep evacuation, and set of time is 20 ± 5s；
7) under, room is inflated, and the time is set as 50 ± 5s；
After above-mentioned steps, i.e. obtain described solar panel.
The solar panel now obtained is not punch and the assembly of trimming, so that product is convenient for carrying and more
Add attractive in appearance, this solar panel can be put into default laser cutting machine and cut, ensure during cutting not damage battery
Sheet 31 and described interconnector.As in figure 2 it is shown, installing hole 120 can be cut out in the four of this solar panel corner, permissible
Installing hole 120 wears lanyard, to facilitate the hook of solar panel；And it is possible in the first cell piece group and second
Modification hole 130 is set between in cell piece group, to facilitate the folding of product, also makes product more attractive in appearance.
The preparation technology of the solar panel that the embodiment of the present invention is provided, the design parameter of each step, be all
Drawing through repeated tests, the molding to product is most important.Such as, pressurization is divided into pressurization for the first time and second time to add
Pressing, and twice pressurization and lamination are provided with different pressure, pressure mainly have impact on the conjugation of multilayer material, and different
Pressure values must in order, and otherwise product there will be the formation unfavorable condition such as bubble, bad, the air spots of feel.And at layer
Pressing through journey, temperature is set as 142 ± 5 DEG C, and temperature is too high, can cause the damage of integral material, and temperature is too low, can cause multilamellar material
The conjugation of material is inadequate.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection domain of the claims in the present invention
Within.
