Description
Technical field
The utility model is related to technical field of solar, more particularly to a kind of solar energy knapsack.
Background technology
With fossil energy peter out and carbon emission caused by greenhouse effects it is increasingly severe, development and application can
Regeneration clean energy resource has become the common recognition of modern social development.Solar energy is inexhaustible, the nexhaustible cleaning energy of the mankind
Source, therefore, the photovoltaic products based on solar cell just constantly enter in the life of people.Many solar power stations are
Or it is under construction, the photovoltaic module based on roof solar cell panel, which have also been obtained, to be widely applied.But in addition,
Photovoltaic products are also no generally to be used in daily life by people.
In fact, photovoltaic products have universal purposes, especially out of doors.For example, solar recharging knapsack is exactly a kind of
The product of green energy conservation.But it often requires that not easily broken and light weight flexible thin-film solar cell piece makes component, and
Polysilicon and monocrystaline silicon solar cell piece are due to its rigidity and the property of easy fragmentation, while the encapsulation of component uses glass again
Glass, causes product heavy, although thus its efficiently, stably, cheaply and ample supply and prompt delivery, be not suitable for solar energy knapsack etc. just
Take the application of formula product.But the current price of flexible thin-film solar subassembly product is higher and lacks the stable source of goods, greatly limits
Their applications in these outdoor portable products are made.
But this has no effect on a series of relevant portable lights that photovoltaic products are expedited the emergence of due to its market potential value
Lie prostrate products application patented technology and some come into the product in market.For example, one, U.S. production CIGS fexible films
The listed company Ascent Solar of solar cell, its flexible solar charge prepd EnerPlex brands are successfully squeezed into
The maximum mobile phone providers Verizon in U.S. supply chain, income is also from 1,000,000 dollars of 2012 within two years
5,000,000 dollars in 2014 are increased, but are deducted after cost and operation consumption, its net income is but from the loss two of 2012
1009000000 dollars increase 2014 5,001,000,000 dollars of loss, the also interior slump in the previous year of its company's value of stocks
85%.The basic reason for this phenomenon occur is that production marketing price is far below cost, so as to be absorbed in, production is more, and loss is got over
The vicious circle of weight.In Chinese market, similar charger product such as solar energy knapsack charger and charging bag etc. can also be bought,
But these products overwhelming majority is based on fexible film component.Crystal silicon product thick and heavy collapsible charging clip for whole rigidity；Or
Person opens a slight glass window on knapsack, but because its area is too small without use value.Due to the fexible film sun
Can the current market price of battery be far above crystal-silicon battery slice, and the source of goods is unstable and make the price superelevation of these products so that
Lack the market competitiveness.
The patent of China and countries in the world, document and disclosed information retrieval are found, such as solar energy knapsack, it is most of
Patent of invention or utility model relate only to the product of generalities, such as using cell panel, do not describe but which kind of cell panel and its
Construction is with making, and in terms of its product, can only be flexible thin-film solar component undoubtedly.It is related to component and its making individually.
Application number CN201520192601.7 Chinese utility model patent discloses a kind of solar energy knapsack, and utility model explanation is used
Be flexible solar battery.Application number CN201520227147.4 Chinese patent has used convex lens in its solar energy knapsack
Mirror optically focused, though cell piece photoelectric conversion efficiency can be improved, not only cost is high, also greatly increases weight.
At present, only only a few prior art has used crystal-silicon battery slice as solar energy knapsack, such as Application No.
Disclose a kind of multifunctional intelligent solar energy knapsack in CN201120329024.3 Chinese utility model patent, but from its
Visible in accompanying drawing, the utility model is not knapsack but back of the body case, huge and heavy, poor for applicability.
In summary, the product that either in the market has occurred, or the prior art disclosed in patent, using knapsack as
The Portable photovoltaic product of representative is substantially to be developed based on flexible thin-film solar component.Their not only prices, electricity
Pond piece also lacks stable sources of supply.And crystal-silicon battery slice is although cheap, performance is stable, photoelectric transformation efficiency is high and market is supplied
Should abundance, but due to the too limitation such as again after not bent, frangible, glass-encapsulated itself, be not suitable for the application of portable product.
The invention provides a kind of practicable crystal-silicon battery slice method for packing, the material of rigidity and light weight is employed as the back of the body
Plate, panel is made with reference to waterproof membrane, so that the assembly quality after crystal-silicon battery slice encapsulation is light and not easily broken.Inventor is to envelope
Blade assembly after dress carries out some stress and impact test shows, as long as without destruction deliberately, it is used in the present invention
Crystal-silicon battery slice is not allowed fragile.Simultaneously by the connection in series-parallel connection between different size crystal-silicon battery slices, the present invention can be city
Field, which is provided, possesses the cheap and good-quality portable type solar energy product of high-conversion rate.
