Description
Technical field
The utility model relates to a kind of solar-energy photo-voltaic cell electricity generation system, especially a kind of electricity generation system that strengthens solar-energy photo-voltaic cell generating output and reduce the solar-energy photo-voltaic cell usage quantity.
Background technology
Existing solar-energy photo-voltaic cell electricity generation system is to be formed by solar-energy photo-voltaic cell silicon chip and polymethyl methacrylate lamination.Wherein solar-energy photo-voltaic cell is generally traditional dull and stereotyped fixed solar photovoltaic cell panel, and its watch crystal is by polymethyl methacrylate with solar-energy photo-voltaic cell sheet contact laminating together.In actual applications, this design can't be avoided " tropical island effect ".After " tropical island effect " is meant and drops on the photovoltaic cell surface by other opaque extinction objects such as fallen leaves, birds droppings, under strong sunshine, form hot spot and then damage the effect of solar-energy photo-voltaic cell conductive mesh.Because each solar-energy photo-voltaic cell sheet series connection back forms an integral body and carries out lamination and encapsulation again in the plate type solar photovoltaic cell component, thereby the local damage meeting of " tropical island effect " single solar-energy photo-voltaic cell sheet of being caused causes scrapping of monoblock unit.Solar-energy photo-voltaic cell was not scrapped, and " tropical island effect " also can influence the average life span of solar-energy photo-voltaic cell sheet greatly.Data are reported according to statistics, and " tropical island effect " makes be reduced by at least 10% the actual life of plate type solar photovoltaic cell component.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that above prior art exists, and a kind of solar-energy photo-voltaic cell electricity generation system that can prevent that above-mentioned " tropical island effect " takes place is provided, and this system can increase light intensity, overcome the low defective of solar radiation energy-flux density, thereby obtain more electric energy output, reduce and use expensive solar-energy photo-voltaic cell and cost of electricity-generating.
In order to realize above-mentioned purpose, can adopt following technical scheme: the solar photovoltaic cell concentrating generating system of this programme is the same with prior art, comprise solar-energy photo-voltaic cell, its improvement is also to comprise a solar-energy light collector, and this beam condensing unit comprises:
A support, this support comprise a following square frame, above the framework of a polygon-octagonal, be fixed with a pole respectively at each angle point place of this octagonal framework, the lower end and the square frame of this pole are fixed together;
The safety glass of a slice high transmission rate be fixed on support above; Eight speculums are separately fixed between two poles of above-mentioned support side and form an octahedra speculum;
One with big square solar-energy photo-voltaic cell such as square frame be fixed on this square frame above.
Above-mentioned solar-energy photo-voltaic cell can be selected a block length and the wide square solar-energy photo-voltaic cell that is respectively 12.5 centimetres for use.The upper surface of solar-energy photo-voltaic cell to the distance of cradle top surface is preferably 25-28 centimetres.The safety glass of high transmission rate can be selected polymethyl methacrylate.
The beneficial effects of the utility model are:
1, with the solar-energy photo-voltaic cell of same quantity, reality can be exported electric weight increases by 4 times.Because the glass of one deck high transmission rate is arranged above each beam condensing unit, with the solar-energy photo-voltaic cell sheet suitable distance is arranged, this structure has fundamentally been eliminated the condition that " tropical island effect " forms.Therefore, the utility model prolongs 10% at least than flat board in actual applications fixed actual life, and will bring the greater power generation amount longer useful life, thereby brings bigger economic benefit.
2, the utility model has been considered the various abominable bad border that may run in the practical application influence to system reliability especially, the impact that causes as hail, stone, sand and dust etc." safety glass " that the designer selects for use a kind of special process to make is encapsulated in the surface of each beam condensing unit; guarantee that this beam condensing unit is under the most serious impact; watch crystal only be the cracking and not broken, thereby guarantee that photovoltaic cell all is subjected to good protection under worst environmental condition.What is particularly worth mentioning is that with common tempering glassy phase ratio, " safety glass " of this special process not only cost is cheap but also have a high transmission rate.Therefore, native system has the stronger impact resistance that is enough to resist various adverse circumstances.
3, native system is made up of the beam condensing unit that a common photovoltaic cell and octahedra speculum surround.The effect of octahedral beam condensing unit is, sunlight is folding and gather together by the method for plane reflection, forms 4 times sun light intensity and impinges upon equably on the photovoltaic cell bottom the beam condensing unit.For example under a sunlight intense irradiation peak power only then to bring up to 4 times for the actual power of each photovoltaic cell of 2.2W be about 8.8W, so can reduce cost of electricity-generating about 50%, reduce by the 70% present use that still belongs to the photovoltaic cell of highly energy-consuming in manufacturing process, high pollution.
In order to make the utility model be convenient to understand, it is described further below by drawings and Examples with more clear.
