Yunanengji Quyosh panellari, fotoelektr panellari sifatida ham tanilgan, bir nechta quyosh batareyasi modullaridan yig‘iladi. There are many types of photovoltaic panels, the most common and most commonly used are: monocrystalline silicon panels.
The performance parameters of monocrystalline silicon solar cells are relatively stable, and they have the highest photoelectric conversion efficiency among all types of panels. The monocrystalline silicon in the panels is generally encapsulated with tempered glass and waterproof resin, which makes it have a long service life and is suitable for use in southern areas with more rainy days and relatively insufficient sunlight.
The production process of amorphous silicon panels is simple, the consumption of silicon materials is very small, and it can also generate electricity under weak light conditions, which is suitable for use in areas with insufficient outdoor sunlight. In rural areas, quyosh ko'cha chiroqlari uzoq xizmat ko'rish muddatiga ega, va kelajakda ko'p muammolarni kamaytirishi mumkin, parvarishsiz. Quyosh panellari quyosh ko'cha chiroqlarining asosiy tarkibiy qismlari. Kunduzi, Quyosh panellari quyosh nurini yutadi, quyosh energiyasini elektr energiyasiga aylantiradi, va uni energiya saqlash qurilmalarida saqlaydi. Kechasi, energiya saqlash moslamasidagi elektr energiyasi avtomatik ravishda yorug'lik energiyasiga aylantiriladi.
Fotovoltaik modullarning hayoti ularning elektr ishlab chiqarish samaradorligi bilan belgilanadi, PN birikma bog'lanish darajasi va kremniy gofretlarning tozaligi bir xil yorug'lik ostida quyosh paneli elektr ishlab chiqarish zichligini belgilaydi. Vaqt o'tishi bilan, PN birikmasi buzilishda davom etadi, shuning uchun samaradorlik pasayishda davom etadi. Konvertatsiya samaradorligi yuqori 90% keyin 16 yil, va u taxminan tushadi 85% keyin 25 yil, so the life of the photovoltaic module is basically more than 20 yil.
The hot spot effect refers to the fact that in a normally working battery module, at a certain moment, a single cell is blocked by a small object, resulting in a decrease in the current that this single cell can generate. The single cell in the battery module can be regarded as a P-N junction structure similar to a diode structure. When the current that the blocked single cell can generate is less than the current of the circuit, this single cell has a negative voltage and becomes a load.
The hot spot effect is also closely related to the production process of battery components. Due to defects in the production level, the internal resistance of the single battery is often uneven. Ichki qarshiligi notekis bo‘lgan batareya uyalari issiq nuqta hodisasiga moyil. Issiq nuqta effekti batareya uyalariga juda zararli. Eng kamida, batareya yadro yonadi, va eng yomoni, butun batareya komponenti yonadi.
