I-Potential induced degradation (PID) ihlasele imboni yelanga kusukela imvelaphi yayo.Lokhu kwenzeka lapho uhlangothi lwe-DC olunamandla kagesi elanga lufakwe eduze kwezinye izinto ezisetshenziswayo ezinama-voltage ahlukile.Umehluko ungabangela ukufuduka kwe-sodium, lapho ama-electron avalelwe kumojuli yengilazi yokuphunyuka futhi asheshise ukuwohloka kwemojuli.
"Lobo bukhulu obukhulu bemvelo buqhuba lokhu kuziphatha kwe-PID, uma amamojula noma amandla kagesi aklanyelwe ngendlela ethile ukunciphisa lokhu," kusho uSteven Marsh, umqondisi omkhulu wezobuchwepheshe kanye nokuklama kunjiniyela omkhulu we-Origis Energy.
Amamojula amafilimu azacile angenwa kalula yi-PID ngenxa yamandla kagesi aphezulu kanye nokwakheka kwezinto ezibonakalayo, kodwa amaphaneli e-silicon ecwebezelayo nawo asengozini. uma kukhona amaphutha kuma-wafers.I-Developer Silicon Ranch ibeka phambili ukusebenza kwe-anti-PID kuma-inverter ezintambo kuzo zombili izinhlobo zamaphrojekthi.
“Zenziwe zahluka, kodwa ziyafanagukhathazeke ukuthi umklami welanga kufanele abe, okuyilezi buthakathaka ezincane kuamaphaneli elanga, uyaziqapha ngezinto ezilwa ne-PID kweyakhoama-inverters,” kusho u-Nick de Vries, i-SVP yezobuchwepheshe nokuphathwa kwempahla eSilicon Ranch.
Uma ubuchwepheshe obusha bephaneli buphuma, ngokuvamile kuthatha isikhathi ukucija umkhiqizo ukuze kuncishiswe ubungozi be-PID.Amamodeli wakuqala wamamojula we-bifacial glass-on-glass ayenezinkinga nge-PID, kodwa abakhiqizi benze izinyathelo kusukela lapho, kusho uMarsh.
“[I-PID] ibuya ngezikhathi ezithile njengoba ubuchwepheshe buthuthuka, ngenxa nje yokuthi busha kakhulu futhi buyathuthuka.Kuyisimo esinzima kakhulu okumele sidlule kuso amamojula,” kusho yena.
Ama-inverters amaphakathi awukubheja okuphephile kokugwema i-PID.Zihlanganisa ama-transformer akhelwe ngaphakathi anesisekelo esibi, ahlukanisa izinhlangothi ze-DC ne-AC zohlelo.
Kepha njengoba ama-inverter ezintambo ezingenawo amandla esetshenziswa ngokuya kusetshenziswa kumaphrojekthi amakhulu ukuze kube lula kwawo kwe-O&M, anamaphaneli amafilimu amancane nokunye, abanikazi bephrojekthi manje kufanele bacabangele ukuncishiswa kwe-PID.
"Kunezindlela ezimbalwa ezibalulekile ongathola ngazo ukuhlukaniswa kwe-galvanic, futhi i-transformer ingenye yazo.Ukwenza lolo shintsho lube yi-transformer ngeshwa kudala leyo nkinga,” kusho uMarsh."Uhlu lwe-PV luzogcina luntanta, futhi ngokuvamile lokho kusho ukuthi cishe uhhafu wamamojula ohlelweni lonke uzothola ukuchema okungalungile okuhlobene nomhlabathi."
Izindlela ezimbalwa zingasetshenziswa ukusiza ukugwema i-PID kuma-inverter ezintambo ezingenasici.Izifaki zingangeza isiguquli sokuhlukanisa esisekelwe phansi noma basilise isiguquli esikhuphukela phezulu ngasohlangothini lwe-AC.Futhi abakhiqizi manje sebengeza ihadiwe ekhethekile nesoftware kuma-inverters ezintambo ukulwa ne-PID.
UMarsh uthe kunezigaba ezimbili zokunciphisa i-PID ochungechungeniama-inverters- Izindlela ezisebenzayo zokulwa ne-PID kanye nezindlela zokuthola kabusha ze-PID.Izingxenyekazi zekhompuyutha ezisebenzayo ezilwa ne-PID nezixazululo zesofthiwe zithatha uhlangothi lwe-DC lwesistimu futhi zikhuphule amandla kagesi ukuze wonke amamojula abe ngaphezu komhlabathi.Ngakolunye uhlangothi, izindlela zokubuyisela i-PID zisebenza ebusuku ukuze zihlehlise i-PID eqoqwe emini.Kodwa-ke, umkhiqizi wefilimu emincane i-First Solar uthi amamojula ayo asabela kahle ekusebenzeni okusebenzayo kwe-anti-PID kunokutholwa kwe-PID.
Abakhiqizi abambalwa abaguqula izintambo emakethe manje bahlanganisa izingxenyekazi zekhompiyutha ezilwa ne-PID kanye nesofthiwe ehambisana nayo ukuze bavikeleke ekonakalisweni, noma bathengise izesekeli ezihlukene ukuze benze imisebenzi yokuvikela.Isibonelo, i-CPS America inikeza i-CPS Energy Balancer, kuyilapho i-Sungrow yakha ihadiwe ye-anti-PID kuma-inverter ayo e-SG125HV kanye ne-SG250HX.I-Sungrow iqale ukunikeza ama-anti-PID string inverters cishe ngo-2018.
"Kwakunemibuzo mayelana namazinga okuwohloka kwamaphaneli ngokujwayelekile ngaleso sikhathi, ngakho-ke sathuthukisa isisombululo," kusho uDaniel Friberg, umqondisi wemikhiqizo nobunjiniyela e-Sungrow.
I-Yaskawa Solectria isanda kumemezela inguqulo ye-anti-PID yochungechunge lwayo lwe-XGI 1500-250 inverter eklanyelwe ukusebenza namamojula wefilimu encane ye-First Solar.
“Lokho kuthatha izinguquko ezincane ezimbalwa zangaphakathi ku-inverter.Akuyona into enkulu, kodwa idinga isikhathi esithile sobunjiniyela kanye nokubuyekezwa kohlu lwemodeli ethile entsha kulolu chungechunge, ngakho-ke siphakathi kokufakazela lokho endaweni, ”kusho uMiles Russell, umqondisi womkhiqizo. ukuphathwa e-Yaskawa Solectria Solar.
Kokubili i-Solectria ne-First Solar zenza imikhiqizo yazo e-United States, inikeze abafaki ukubhanqa okulula ukuze bafinyelele imigomo yesikhuthazo sokuqukethwe kwasekhaya efakwe ku-IRA.Kodwa baxoxisane kahle ngokuncishiswa kwe-PID ngaphambi kokuba i-IRA ibhalwe.
“Saqala lobo budlelwano eminyakeni emibili edlule, sinomgomo osezingeni eliphezulu ukuze sithole umkhiqizo ohambisana kalula nomkhiqizo wethu,” kusho u-Alex Kamerer, umphathi wephrojekthi kwa-First Solar."Sithatha leso sinyathelo esengeziwe sokuqinisekisa ukuthi siyasebenzisana nabahlinzeki besistimu yethu, okuzuzisa amakhasimende ethu."
Yize abakhiqizi abaningi be-inverter sebeqala ukufaka imisebenzi elwa ne-PID kuma-inverter ezintambo njengoba ubuchwepheshe busetshenziswa ngokuya kumaphrojekthi amakhulu, onjiniyela kwesinye isikhathi kusadingeka bambe amashidi edatha ukuze bahlole amandla omkhiqizo wokulwa ne-PID, ngokusho kwe-Origis's Marsh.
"Sithola ukuthi kunezinketho ezimbalwa laphaya, futhi aziwona umshayeli omkhulu ezindlekweni zokuqala ze-inverter," esho.“Kodwa-ke, lezi azijwayele ukudalulwa kakhulu ngezici ze-inverter, mhlawumbe ngenxa yokuthi isihloko sinobuchwepheshe kakhulu, noma [ngoba] i-PID ngokwayo inzima kakhulu ukuyibona ensimini.Ngakho-ke siyawabona ama-inverter angenawo ama-transformer aza ngaphandle kwalo msebenzi. ”
Kodwa ukunciphisa i-PID kuzoba okubaluleke nakakhulu njengoba izinkampani zesola manje zinenketho yokuthatha ikhredithi yentela yokukhiqiza (PTC) ku-IRA.Ukugcina ukonakala ukuze amamojula akhiqize amandla amakhulu isikhathi eside ngangokunokwenzeka kuzobaluleka ekuqinisekeni kwekhredithi yentela.
"Ngicabanga ukuthi ukuqonda kabanzi kwemboni yezici ze-PID cishe yilokho okudingeka kwandiswe - imfundo mayelana nezikhathi lapho amamojula akho angase athambekele ku-PID, kanye nezindlela zokubona," kusho uMarsh.
