雙玻光伏組件介紹
About double glazing panel
交大光谷雙玻光伏組件,是指由兩片玻璃和太陽能電池片組成複合層,電池片之間由導線串、並聯彙集到引線端所形成的光伏電池組件。
The
utility model relates to a double glass photovoltaic component, which is acomposite layer composed of two pieces of glass and a solar battery sheet,wherein, the photovoltaic cells are formed by the connection of the wires in
series and in parallel to the lead end of the battery.雙玻光伏建築可以分為BIPV、BAPV兩種形式。BIPV(光伏建築一體化)是說,光伏組件作為建築的構件,是建築的一部分。它的特點是,除了要滿足組件的性能要求以外,還要防火,並滿足建築力學、熱舒適、採光、隔音等的一些建築要求。BAPV指的是光伏組件作為建築的一個附件,這一塊就相對比較簡單,只要滿足光伏組件的一些性能要求就可以。當然,它要跟建築結合,所以也要做一些防火的測試。
Dual
glass photovoltaic architecture can be divided into two forms: BIPV and BAPV.BIPV (photovoltaic building integration) is that photovoltaic components asbuilding components, is part of the building. It is characterized by, inaddition to meeting the performance requirements of components, but also fireprotection, and meet construction mechanics, thermal comfort, lighting, soundinsulation and other architectural requirements. BAPV refers to the PV modulesas an annex to the building, this piece is relatively simple, as long as the
photovoltaic components meet some of the performance requirements can be. Ofcourse, it should be combined with the building, so it is necessary to do somefire prevention tests.交大光谷雙玻組件可以做成各種顏色。其次,它可以擴展多種形式,可以加工成中通的結構來隔熱,或者隔雜訊,還可以做成各種透光率,滿足建築的採光要求。再次,它結構對稱。這個特點可以說是光伏組件的特點。比如說,承受靜態載荷之後,電力片可以做到無隱裂。因為晶體硅電池有一個最大的缺點就是非常脆,很容易發生破碎。
但在對稱結構當中,它承受外力的時候,可以做到不會破碎,在這種載荷之後,它功率衰減非常小。這個跟它的力學對稱結構是相關的。它在冷熱循環中功率衰減也非常小。
The double glass component can be made
into various colors. Secondly, it can be extended in many forms, and can beprocessed into a medium to pass structure to insulate the heat or noise. It canalso be made into all kinds of light transmittance to meet the lighting
requirements of the building. Once again, it is structurally symmetrical. Thisfeature can be said to be the characteristics of PV modules. For example, afterthe static load is applied, the power slice can be cracked free. Becausecrystalline silicon cells have one of the biggest drawbacks is very brittle,very prone to fragmentation.But in a symmetrical structure, when it
is subjected to external forces, it can not be broken, and after such a load,its power attenuation is very small. This is related to its mechanicalsymmetric structure. It also has very little power attenuation in the hot andcold cycles.
在BAPV形式中,它附著在傾斜的屋面的形式,通常是作為建築的附件,會增加建築的負荷能力。它的哪些特點比較適合在BAPV上應用呢?第一,它外表面都是玻璃結構。玻璃結構抗紫外能力非常強,防火等級也比較高,可以很輕鬆地做到1500伏的系統電壓。當然,如果你是用1000伏的電壓的話,代表了它的絕緣性能非常好,它的安全性會更高。即便是老化之後的玻璃,絕緣性也非常好。第二,它沒有金屬邊框,相對普通組件來說,它省去了接地的操作,這樣可以避免PID(電位誘發衰減)現象的產生。當然,我們如果說能夠把水膜去掉,能夠把在迴路過程中的任何一個點打斷,同樣也不會有PID產生。
沒有邊框後,組件的工作溫度會變低。同時,它還能防止灰塵的積攢。第三個特點還是結構對稱,對於組件來說依然是在載荷之後電力片無引力,功率衰減小,TC循環過程中功率分解小。
In the form of BAPV, it is attached to an inclined roofing form, usually
as an attachment to the building, which increases the load capacity of the building.What are its features suitable for use on BAPV? First, it has a glass structureon its outer surface. The structure of glass is very resistant to UV, and thefire rating is relatively high. It can easily achieve the system voltage of1500 volts. Of course, if you are using 1000 volts of voltage, it stands forits very good insulation performance, and its security will be higher. Even
after aging, the insulation of the glass is very good. Second, it does not havea metal frame, and it eliminates grounding operations relative to the ordinarycomponents, thus avoiding the generation of PID (potential inducedattenuation). Of course, if we say that we can remove the water film andinterrupt any point in the loop process, there will be no PID.Without a border, the components operating temperature will be low. At
the same time, it can prevent dust accumulation. The third feature isstructural symmetry. For the component, it is still in the load, the powersheet has no attraction, the power attenuation is small, and the powerdecomposition in the TC cycle is small.
在沒有邊框之後,它的工作溫度較常規的組件會低2~5攝氏度,發電量高1%~2%,原因是常規組件鋁合金邊框內部不利於空氣的對流。沒有邊框之後,對流就會明顯加強,造成組件的溫度下降。當組件和屋頂安裝的距離非常近的時候,對流是更差,所以雙玻組件更適合在斜面屋頂上安裝,在這種情況下,它溫度的降低會體現的更加明顯。
舉一個例子,比如有人踩在雙玻組件上,電池片本身是有彎曲的,但是電池片本身的程度沒有變化。所以說,電池片又承受了這樣一個拉伸和壓縮的力,尤其是在拉伸的過程中,電池片非常容易產生引力。這對於TC循環過程中的道理來說是一樣的。
TC代表的是熱脹冷縮、溫度循環,材料也會發生膨脹和收縮。對於力學的對稱結構來說,對電池片的影響就非常小。我們在實驗室對雙玻組件做了一些老化的測試,有高溫高濕、冷熱循環、PID、紫外線,試驗中的條件都是2倍於IEC的標準,UV的話可能就是6倍了。實驗之後,雙玻組件的功率衰減值為2%,尤其是PID,基本上小於1%。基於測試的結果,雙玻組件的功率質保是30年,並且從第二年開始每年的功率衰減不大於0.5%,而常規組件的則分別是25年和0.7%。
After no borders, its operating temperature is 2~5 degrees Celsius lower
than the conventional components, generating 1%~2% higher, due to the fact thatthe aluminum alloy frame inside the conventional components is not conducive toconvection in the air. Without the bezel, the convection will be significantlyenhanced, causing the component to drop in temperature. Convection is worsewhen the component is close to the roof, so the double glazing is more suitable
for mounting on the sloping roof, in which case the temperature drop willmanifest itself more clearly.For example, for example, if someone is stepping on a double glass
component, the battery itself is bent, but the extent of the battery itself hasnot changed. So, the battery also bears such a tensile and compressive force,especially in the process of stretching, the battery piece is very easy togenerate gravity. This is the same thing for the TC process.TC stands for expansion, contraction, temperature cycling, and expansion
and contraction of materials. For the symmetrical structure of mechanics, the effecton the battery is very small. We have done some aging tests on double glass
components in the laboratory. We have high temperature, high humidity, hot andcold cycles, PID and UV. The conditions in the test are 2 times the standard ofIEC, and UV may be 6 times that. After the experiment, the power attenuationvalue of the double glass component is 2%, especially PID, basically less than1%. Based on the test results, the power rating of the dual glass component is30 years, and the annual power attenuation is not greater than 0.5% from secondyears, while the conventional components are 25 and 0.7% respectively.1. 交大光谷雙玻組件(BIPV—光伏建築一體化)結合鋼結構和建築特點,靈活,易安裝,是上海交谷太陽能科技有限公司研究開發的重點和強勢產品,實現了建築美觀和環保發電雙重功效的美譽。
