Segondè efikasite ak fyab nan modil fotovoltaik pandan sik lavi a se de konotasyon enpòtan nan bon jan kalite a nan jenerasyon pouvwa fotovoltaik. Pou yon tan long, Trina Solar te kòmanse soti nan sous la nan bon jan kalite a nan modil fotovoltaik - materyèl kle, pran durability nan anviwònman an nan materyèl kòm objè a evalyasyon, chwazi materyèl ak transmisyon segondè, segondè rezistans ak segondè rezistans move tan, ak peye atansyon sou pèfòmans nan modil fotovoltaik nan tout sitiyasyon an sik lavi.
01
Riban fotovoltaik
Fotovoltaik Welding Strip
Riban fotovoltaik (ribbon fèblan -kouvwi kòb kwiv mete): Li se sitou divize an teren entèkoneksyon ak teren otobis. Bann entèkonekte yo sitou itilize nan koneksyon ki genyen ant selil fotovoltaik modil pou fè elektrisite ak kolekte aktyèl selilè; andedan bwat junction la.
Rezistans teren soude: Li se sitou detèmine pa gwosè a nan teren an soude tèt li ak materyèl la nan substra an kwiv.
Echèk akòz riban:
①Virtual soldering and over-soldering: Too low soldering temperature, uneven application of flux and many other reasons can lead to false soldering, while too high soldering temperature or too long soldering time can lead to over-soldering. False welding will cause the welding tape to separate from the cell during the actual use of the module, and the power of the module will be attenuated.
② Welding ribbon offset: Due to the abnormal positioning of the welding machine, the contact between the welding ribbon and the battery area is reduced, and delamination, power attenuation and other phenomena occur. With the increase of the busbars of the battery, the width (diameter) of the welding strip is getting narrower and narrower, which requires higher positioning accuracy of the welding machine.
02
Bwat Junction
Bwat Junction fotovoltaik
Fonksyon bwat junction la: li enstale sou modil fotovoltaik la pou transmèt aktyèl la. Pandan itilizasyon nòmal, li gen pwoteksyon apwopriye pou anpeche enfliyans nan anviwònman ekstèn ak domaj posib ki te koze pa manyen kò a ap viv andedan bwat la junction.
Kondisyon pèfòmans: Pandan ke gen bon pèfòmans elektrik, konsepsyon ak gwosè bwat junction la dwe satisfè kondisyon anviwònman an itilize, tankou: elektrik, mekanik, rezistans chalè, rezistans korozyon ak rezistans move tan. An menm tan an, li pa dwe lakòz domaj nan itilizatè yo ak anviwònman an.
Bwat junction entelijan: sikwi entèn nan bwat junction modil tradisyonèl la konpoze de ba otobis ak dyod, epi pa gen okenn lòt konpozan elektwonik tankou tablo sikwi elektwonik. Suivi MPPT nan sistèm fotovoltaik reyalize pa varyateur oswa kontwolè. Eleman entelijan an se ke tablo sikwi enprime oswa konpozan elektwonik ki gen rapò yo entegre nan eleman an ak entegre andedan bwat la junction pou reyalize eleman -optimize nivo, deteksyon ak kontwòl. Eleman entelijan pèmèt tranzisyon an soti nan kontwòl pasif a aktif.

ankadreman alyaj aliminyòm
ankadreman alyaj aliminyòm
Wòl nan ankadreman an aliminyòm: Premyèman, pwoteje kwen an nan glas la; Dezyèmman, alyaj aliminyòm konbine avèk jèl silica ranfòse pèfòmans sele modil la; Twazyèmman, amelyore anpil fòs mekanik an jeneral nan modil la; Katriyèm, fasilite enstalasyon an ak transpò nan modil la; Katriyèm, pote modil la Konpayi asirans lyen ak bracket la ka reyalize pi bon kapasite chaj anti-nan fikse, soti nan fikse inite a entegrasyon, amelyore kapasite mekanik sistèm estasyon elektrik la.
A pwezan, rechèch sou karakteristik aliminyòm branka pou pote materyèl 6063-T5 ak 6005-T6: T5 repwezante solisyon tretman plis enkonplè atifisyèl vieillissement / T6 repwezante solisyon tretman plis nèt sou tout pwen atifisyèl moun ki aje.
①Solid solution treatment: It refers to the heat treatment process in which the alloy is heated to a high temperature single-phase region and maintained at a constant temperature, so that the excess phase is fully dissolved into the solid solution and then rapidly cooled to obtain a supersaturated solid solution.
②Incomplete artificial aging: Use a relatively low aging temperature or a short holding time to obtain excellent comprehensive mechanical properties, that is, to obtain relatively high strength, good plasticity and toughness, but the corrosion resistance may be relatively low.
③Complete artificial aging: Using a higher aging temperature and a longer holding time, the maximum hardness and the highest tensile strength are obtained, but the elongation is low.
Nan pwosesis pwodiksyon an, alyaj aliminyòm kalite T6 a fòme pa extrusion tanperati ki wo, ak eta a atifisyèl aje apre tretman chalè solisyon (trempe) se refwadisman dlo, pandan y ap alyaj aliminyòm kalite T5 a refwadi pandan pwosesis la fòme extrusion tanperati ki wo, ak Lè sa a, atifisyèlman ki gen laj se lè refwadisman. Konpare ak de metòd refwadisman yo, dite pwofil la apre refwadisman dlo T6 yo pral pi wo, men plastisit ak severite pwofil la pral afekte.
At present, my country's photovoltaic industry ranks among the top in the world in terms of manufacturing scale, industrialization technology level, application market expansion, and industrial system construction. However, the photovoltaic industry is developing rapidly, especially the technological progress is extremely rapid, and the industry is in a period of rapid change. High-quality auxiliary materials for photovoltaic modules are an important guarantee for the high efficiency and reliability of modules, and should be paid more attention by the industry. At the same time, how to achieve high efficiency and low cost on the premise of ensuring the life and reliability of photovoltaic modules, and the cost reduction and efficiency increase of auxiliary materials are also crucial.
