Quyosh batareyasi, shuningdek,"fotovoltaik hujayra" yoki"quyosh chipi", yorug'lik energiyasini elektr energiyasiga aylantiradigan nozik yarim o'tkazgichli varaqdir. Ammo bunday yoriqlar juda mo'rt va agar ular elektr energiyasini ishlab chiqarish uchun to'g'ridan-to'g'ri dalaga joylashtirilsa, u albatta ishlamaydi. Shuning uchun, uni ishlatishdan oldin uni himoya qilish va quyosh paneli ichiga o'rash uchun boshqa materiallar kerak bo'ladi. Shunday qilib, bugun'ga quyosh panelining tarkibiy qismlarini ko'rib chiqaylik:
1. Solar cells are the core components, which are divided into polycrystalline silicon and monocrystalline silicon cells. Cells are generally relatively small, with two sizes of 125mm and 156mm. It is rectangular, and the cells are closely arranged in series. Usually a panel has 72 or 64 cells.
2. Photovoltaic glass is also called "photoelectric glass", which is a tempered subway glass with very good light transmittance and high hardness. It can adapt to a large temperature difference between day and night and harsh weather conditions. It is covered on the battery sheet to protect the battery sheet.
3. EVA film, the cell is very fragile, the photovoltaic glass cannot be directly attached to it, and the EVA film is required to play a bonding role in the middle. Similarly, there is also an EVA film between the battery board and the backplane to play a bonding role. The light transmittance of EVA film is also very good, but it will turn yellow after contact with air, which will affect the power generation efficiency, so the technical requirements for packaging are very high.
4. Fotovoltaik orqa panel, orqa panel ham hujayralarni himoya qilishda rol o'ynaydi va orqa panel muhrlangan, izolyatsiyalangan, suv o'tkazmaydigan va qarishga qarshi bo'lishi kerak. Material odatda TPT yoki TPE materialidir. Umuman olganda, orqa panelning ishlash muddati shisha va alyuminiy ramkaga qaraganda qisqaroq, ammo u odatda 25 yilga etishi mumkin. Ikki oynali modul ham mavjud, orqa plita ham temperli shishadan qilingan. Ushbu ikki oynali quyosh paneli yaxshi yorug'lik o'tkazuvchanligiga va yuqori energiya ishlab chiqarish samaradorligiga ega.
5. Quyosh alyuminiy ramkasi, quyosh ramkasi alyuminiy qotishmasidan qilingan va uning kuchi va korroziyaga chidamliligi juda yaxshi. U butun panelni qo'llab-quvvatlash va himoya qilish rolini o'ynashi mumkin. Va quyosh panelini o'rnatish teshigi ham ramkada bo'lib, ramka orqali fotovoltaik tayanchga ulanadi.
6. Aloqa qutisi butun batareya platasining energiya ishlab chiqarish tizimini himoya qiladi. Bu joriy uzatish stantsiyasiga teng. Batareyada qisqa tutashuv mavjud bo'lganda, ulanish qutisi qisqa tutashuvli batareya simini avtomatik ravishda uzib qo'yadi.
7. Silika jeli, silika jeli quyosh panelining chetini va quyosh ramkasini, paneli va birlashma qutisini yopish uchun ishlatiladigan juda yaxshi muhrlangan materialdir. Bizning quyosh ramkasining tirqishi kabi ishlab chiqilgan to'lib toshgan truba silikonning to'lib ketishining oldini olish uchun mo'ljallangan.
