Ib lo lus nug tseem ceeb hauv photovoltaic (PV) module tsim yog seb texturedPrismatic / Matt (PM) qauv iavcompromises mechanical kev ntseeg tau piv rau duntab iavntawm tib lub thickness. Thaum cov kev hloov pauv ntawm qhov chaw microscopic qhia txog qhov sib txawv me me ntawm cov iav raw, thermal ua thiab polymer encapsulation kom ntseeg tau tias muaj kev ncaj ncees sib npaug hauv qhov tiag - ntiaj teb hnub ci kev teeb tsa.
1. Raw Glass State: Stress Distribution vs. Micro-Valleys
Kev ntsuas ob hom iav hauv lawv cov nqaij nyoos, un{0}}tempered xeev qhia txog qhov sib txawv ntawm lub cev tseem ceeb:
Float Glass:Muaj ob lub tiaj tiaj, tsis sib xws. Sab nraud dabtsi yog khoov quab yuam faib tusyees thoob plaws qhov chaw, yielding ib tug ntau dua raw flexural zog pib nyob rau hauv lub chaw soj nstuam.
Patterned iav:Nta microscopic nto geometry (prism / matt ridges). Cov hauv paus ntawm cov micro- qauv tsimmicro- havuas ua raws li cov ntsiab lus kev ntxhov siab me me hauv qab lub cev hnyav heev.
2. Kev sib npaug ntawm cov qauv kev ua haujlwm: Tempering & Lamination
Raw iav yeej tsis siv ncaj qha rau hauv PV modules. Cov txheej txheem tsim qauv qauv tshem tawm qhov sib txawv ntawm lub zog rawg los ntawm ob theem tseem ceeb:
Thermal Tempering:Ob hom iav tau txais lub cev tempering los qhia cov txheej txheem siab compressive ntawm cov iav nto. Cov txheej txheem no ua rau muaj kev cuam tshuam tag nrho thiab khoov tsis kam exponentially piv rau cov iav nyoos.
Polymer Encapsulation (EVA / POE):Thaum lub sij hawm module lamination nyob rau hauv tshav kub thiab siab, polymer encapsulant films (EVA los yog POE) yaj thiab ntws mus rau hauv txhua txhua microscopic kab noj hniav ntawm cov qauv iav. Qhov no kaw cov micro-kwj hav thiab tsim cov qauv sib xyaw ua ke, faib cov khoom siv hluav taws xob sab nraud kom sib npaug thoob plaws lub rooj sib txoos.
3. Tiag -Lub Ntiaj Teb Module Test & IEC Standards
Thaum sib dhos ua tiav PV modules thiab raug kuaj xyuas raws li tus qauvTS EN 61215cov lus qhia:
Static Cua Load (2400 Pa):Ob qho tib si tempered patterned iav thiab ntab iav hla nrog sib npaug ntawm cov txheej txheem margins.
Heavy Snow Load (5400 Pa):Ob hom iav ua kom pom qhov sib npaug ntawm qhov siab ntawm qhov hnyav yam tsis muaj kev tawg.
Hail Impact Resistance:Ob leeg tiv taus cov dej khov nab kuab- kev sim pob cuam tshuam (25 hli txoj kab uas hla ntawm 23 m / s) ntseeg tau.
Technical Summary
Raw Flexural Strength (Un-tempered): Float Glass yog siab dua me ntsisvim tsis sib xws ntawm kev ntxhov siab; Patterned iav muaj cov ntsiab lus kev ntxhov siab me me ntawm cov qauv hauv paus.
Tempered & Laminated Reliability: Equal Performance.Encapsulants sau micro-grooves thiab faib cov khoom sib npaug thoob plaws txheej txheej.
Mechanical Standard Ua raws (IEC 61215): Ib yam.Ob leeg ntseeg tau tiv taus 5400 Pa daus load thiab 2400 Pa cua load xeem.
Zuag qhia tag nrho Engineering tus nqi:Vim cov iav qauv muab ib+1.5% mus rau 2.0% optical zog nceyam tsis muaj kev xyiv fab tiag tiag - lub ntiaj teb durability, nws tseem yog cov txheej txheem cov khoom siv rau siab - kev ua haujlwm hnub ci modules.
