Kev kov yeej ib nrab ntxoov ntxoo nrog ib nrab -Cell Lightweight Solar Panels
Overcoming ib feem Shading thiab Load txwv: Engineering Guide rau Ib nrab -Cell Lightweight Solar Panels
Cov lus qhia kev qhia rau ib nrab -cell lightweight solar panels. Kawm paub yuav ua li cas bypass diode topology, duab ntxoov ntxoo kam rau ua, thiab qis -load mounting optimize coj mus muag PV LCOE.
Kev Ntsuas Kev Ntsuas: Circuit Topology thiab Duab Ntxoo Tolerance Dynamics
Ib nrab shading ntawm kev lag luam rooftops ncaj qha induces localized power mismatch, hotspot txaus ntshai, thiab system efficiency degradation. Standard tag nrho- cell modules txuas nrog hauv series raug kev txom nyem lub zog poob thaum duab ntxoov ntxoo npog ib lub xov tooj, raws li tam sim no ntws hla tag nrho cov hlua yog txwv los ntawm qhov qis tshaj - ua wafer.
Ib nrab - cell lightweight PV modules hais txog qhov kev txwv no los ntawm kev faib lub xov tooj ntawm tes ntev raws li thawj axis, txo qhov tam sim no (I) los ntawm 50% thaum tuav qhov sib npaug (V). Vim hais tias sab hauv resistive zog poob yog xam siv Ppoob = I2R, txo qhov tam sim no sab hauv los ntawm ib nrab txiav thermal kuj poob los ntawm 75%.
Txoj kev sib cais-kev sib tshuam architecture faib cov module rau hauv sab sauv thiab sab qis- cov hlua xaim nyob rau hauv parallel. Nyob rau hauv ib nrab shading tej yam kev mob:
Kev rho tawm tam sim no:Thaum tus qauv kab rov tav duab ntxoov ntxoo cuam tshuam rau qis dua ib nrab ntawm lub module, kev sib xyaw bypass diodes tam sim no nyob ib ncig ntawm cov cuam tshuam sub- hlua.
Nruam tiam:Lub unshaded sab saum toj tswj tuav 50% lub zog tso zis, whereas ib tug pa module nyob rau hauv zoo tib yam tej yam kev mob collapses kiag li.
Kub Kev tswj hwm:Kev ua haujlwm qis dua (4℃txog 6℃txo qis piv rau tag nrho-cov chav nyob ntawm tes) txo qhov kub ntawm- qhov chaw tsim, tiv thaiv cov txheej EVA / POE polymer txheej los ntawm thermal degradation thiab delamination.
Tsawg- lub teeb ua tau zoo yog txhim kho los ntawm kev sib cais- cov txheej txheem ntawm tes laser txiav uas nthuav tawm cov npoo ntawm tes, ua kom cov hluav taws xob sib txawv thaum sawv ntxov, yav tav su, thiab huab cua.
