Potential Induced Degradation (PID) yasokoneza makampani oyendera dzuwa kuyambira pomwe idayamba.Izi zimachitika pomwe mbali yamagetsi yamagetsi yamagetsi yamagetsi yamphamvu kwambiri ya DC imayikidwa pafupi ndi zida zina zokhala ndi magetsi osiyanasiyana.Kusiyanaku kungayambitse kusamuka kwa sodium, pomwe ma electron omwe amatsekeredwa mugalasi ya module yothawa ndikufulumizitsa kuwonongeka kwa module.
"Kukula kwakukulu kumeneku kumayendetsa khalidwe la PID, ngati ma modules kapena magetsi a magetsi sanapangidwe m'njira yochepetsera izi," anatero Steven Marsh, mkulu wa teknoloji ndi mapangidwe a Origis Energy.
Ma module amakanema amatha kutengeka mosavuta ndi PID chifukwa champhamvu kwambiri yamagetsi komanso mapangidwe azinthu, koma mapanelo a crystalline silicon nawonso ali pachiwopsezo. ngati pali zolakwika m'mipando.Wopanga Silicon Ranch amaika patsogolo magwiridwe antchito a anti-PID kwa ma inverters a zingwe pamitundu yonse iwiri yama projekiti.
"Amapangidwa mosiyana, koma ndi gawo lomwelognkhawa kuti mlengi dzuwa ayenera kukhala, amene ndi zofooka zazing'ono izi mumapanelo a dzuwa, mumapewa ndi zotsutsana ndi PID m'moyo wanuma inverters, "Anatero Nick de Vries, SVP wa teknoloji ndi kasamalidwe ka katundu ku Silicon Ranch.
Ukadaulo watsopano ukatuluka, nthawi zambiri zimatenga nthawi kuti ziwongolere malondawo kuti muchepetse chiopsezo cha PID.Zitsanzo zoyambirira za magalasi a galasi pagalasi anali ndi vuto ndi PID, koma opanga apita patsogolo kuyambira pamenepo, Marsh adatero.
"[PID] imabweranso nthawi ndi nthawi pomwe ukadaulo ukusintha, chifukwa ndi chatsopano komanso chikusintha.Ndizovuta kwambiri zomwe ma modules ayenera kudutsamo, "adatero.
Ma inverters apakati ndi kubetcha kotetezeka popewa PID.Amaphatikizapo zosinthira zomangidwa zomwe zili ndi maziko olakwika, kupatula mbali za DC ndi AC zadongosolo.
Koma monga ma inverter opanda zingwe akuchulukirachulukira kuma projekiti akuluakulu chifukwa cha kuphweka kwawo kwa O&M, okhala ndi mapanelo amafilimu opyapyala ndipo mwanjira ina, eni mapulojekiti tsopano akuyenera kuganizira za kuchepetsa PID.
"Pali njira zingapo zofunika zomwe mungakwaniritsire kudzipatula kwa galvanic, ndipo chosinthira ndi chimodzi mwazo.Kupanga kusinthaku kukhala kosasinthika mwatsoka kumabweretsa vuto, "adatero Marsh."Mndandanda wa PV udzatha kuyandama, ndipo nthawi zambiri zomwe zikutanthauza kuti pafupifupi theka la ma module amachitidwe onse amakumana ndi tsankho losagwirizana ndi nthaka."
Njira zingapo zitha kugwiritsidwa ntchito kuthandiza kupewa PID mu ma inverters opanda zingwe.Oyika amatha kuwonjezera chosinthira chokhazikika chodzipatula kapena kuyika chosinthira chokwera kumbali ya AC.Ndipo opanga tsopano akuwonjezera zida zapadera ndi mapulogalamu kuti azimitsa ma inverters kuti amenyane ndi PID.
Marsh adati pali magulu awiri a kuchepetsa PID mu chingwema inverters- Njira zothana ndi PID zogwira ntchito komanso njira zochira za PID.Mayankho a anti-PID ndi mapulogalamu a mapulogalamu amatenga mbali ya DC ya dongosolo ndikukweza magetsi kuti ma module onse akhale pamwamba pa nthaka.Kumbali ina, njira zochira za PID zimagwira ntchito usiku kuti zithetse PID yomwe imasonkhanitsidwa masana.Komabe, wopanga filimu yopyapyala Yoyamba Solar akuti ma module ake amayankha bwino pakugwira ntchito kwa anti-PID m'malo mochira PID.
Opanga zingwe zosinthira zingwe pamsika tsopano akuphatikiza zida za anti-PID ndi mapulogalamu otsatizana nawo kuti ateteze ku kuwonongeka, kapena kugulitsa zida zapadera kuti zigwire ntchito zoteteza.Mwachitsanzo, CPS America imapereka CPS Energy Balancer, pamene Sungrow amamanga zida zotsutsana ndi PID muzitsulo zake za SG125HV ndi SG250HX.Sungrow adayamba kupereka ma anti-PID string inverters kuzungulira 2018.
"Panali mafunso okhudza kuwonongeka kwa mapanelo ambiri panthawiyo, kotero tidapanga yankho," atero a Daniel Friberg, director of product and engineering ku Sungrow.
Yaskawa Solectria posachedwapa yalengeza za anti-PID mtundu wa XGI 1500-250 mndandanda wa inverter womwe umapangidwira kugwira ntchito ndi ma module a First Solar woonda-filimu.
"Izi zimatengera kusintha pang'ono mkati mwa inverter.Sichinthu chachikulu, koma pamafunika nthawi yauinjiniya ndikusintha mindandanda yamitundu yatsopano pamndandanda uno, chifukwa chake tili mkati motsimikizira izi mu labu, "atero a Miles Russell, director of product. Management ku Yaskawa Solectria Solar.
Onse a Solectria ndi First Solar amapanga zinthu zawo ku United States, kupatsa oyika njira yosavuta kuti akwaniritse zolinga zapakhomo zomwe zikuphatikizidwa mu IRA.Koma adakambirana za kuchepetsa PID bwino IRA isanalembedwe.
"Tidayamba ubalewu zaka ziwiri zapitazo, ndikungofuna kuti tipeze chinthu chomwe chimagwirizana ndi zomwe timapanga," atero a Alex Kamerer, woyang'anira polojekiti ku First Solar."Timapita patsogolo kuti tiwonetsetse kuti tikugwirizana ndi omwe amapereka makina athu, zomwe zimapindulitsa makasitomala athu."
Ngakhale opanga ma inverter ochulukirapo akuyamba kuphatikizira ntchito zotsutsana ndi PID m'makina osinthira zingwe popeza ukadaulo umagwiritsidwa ntchito kwambiri pama projekiti akuluakulu, mainjiniya nthawi zina amafunikira kukumba m'mapepala a data kuti ayang'ane zomwe anti-PID ali nazo, malinga ndi Origis's Marsh.
"Tapeza kuti pali njira zingapo kunja uko, ndipo sikuti ndizoyendetsa kwambiri pamtengo woyambira wa inverter," adatero."Komabe, izi sizimakonda kufalitsidwa kwambiri ndi ma inverter, mwina chifukwa mutuwo ndi waukadaulo kwambiri, kapena ngakhale [chifukwa] PID yokha ndiyovuta kuizindikira m'munda.Chifukwa chake tikuwona ma inverter opanda ma transformer omwe amabwera popanda ntchitoyi. ”
Koma kuchepetsa PID kuyenera kukhala kofunikira kwambiri popeza makampani oyendera dzuwa tsopano ali ndi mwayi wotenga ngongole yamisonkho (PTC) mu IRA.Kusunga kuwonongeka kotero kuti ma modules apereke mphamvu zambiri kwa nthawi yayitali kungakhale kofunikira pa chitsimikizo cha ngongole ya msonkho.
"Ndikuganiza kuti kukhala ndi chidziwitso chodziwika bwino chamakampani pazinthu za PID ndizomwe ziyenera kuwonjezereka - maphunziro okhudza nthawi zomwe ma modules anu angakhale ovuta ku PID, komanso njira zodziwira," adatero Marsh.
