Ukuthotywa okunokubakho okubangelwayo (PID) kuthwaxe ishishini lelanga ukusukela kwimvelaphi yalo.Le nto yenzeka xa i-high-voltage DC icala leprojekthi yelanga lifakwe ecaleni kwezinye izixhobo ezinombane owahlukileyo.Umahluko unokubangela ukufuduka kwesodium, apho ii-electron zivalelwe kwimodyuli yeglasi yokuphunyuka kunye nokukhawulezisa ukuthotywa kwemodyuli.
"Obo bukhulu budala buqhuba le ndlela yokuziphatha ye-PID, ukuba iimodyuli okanye i-elektroniki ayenzelwanga ngendlela ethile yokunciphisa oku," utshilo uSteven Marsh, umlawuli omkhulu wetekhnoloji kunye noyilo kumphuhlisi omkhulu we-Origis Energy.
Iimodyuli zefilimu encinci zichaphazeleka ngakumbi kwi-PID ngenxa yamandla ombane aphezulu kunye nokwenza izinto eziphathekayo, kodwa iipaneli ze-silicon zekristale zikwasemngciphekweni. ukuba kukho naziphi na iziphene kwiiwafers.I-Developer Silicon Ranch ibeka phambili umsebenzi wokuchasana ne-PID kwii-inverters zentambo kuzo zombini iindidi zeeprojekthi.
“Zenziwe zahluka, kodwa ziyafanagukhathazeke ukuba umyili elanga kufuneka abe, nto leyo obu buthathaka ezincinane kwiiiphaneli zelanga, uyazilinda ngokuchasene neempawu ezichasene ne-PID kwindawo yakhoii-inverters, "Utshilo uNick de Vries, i-SVP yezobuchwepheshe kunye nolawulo lwe-asethi kwi-Silicon Ranch.
Xa iteknoloji yephaneli entsha iphuma, ihlala ithatha ixesha ukulola imveliso ukunciphisa umngcipheko we-PID.Iimodeli zangaphambili zeglasi-kwiglasi yeemodyuli ze-bifacial zinemiba nge-PID, kodwa abavelisi baye benza umtsi ukusukela ngoko, utshilo uMarsh.
“[I-PID] ibuya amaxesha ngamaxesha njengoko itekhnoloji iguquka, ngenxa yokuba intsha kakhulu kwaye iyavela.Yimeko enzima kakhulu ekufuneka iimodyuli zidlule kuyo,” utshilo.
Ii-inverters ezisembindini zilubhejo olukhuselekileyo lokuphepha i-PID.Ziquka i-transformers eyakhelwe-ngaphakathi esekelwe kakubi, ihlukanisa i-DC kunye ne-AC amacala enkqubo.
Kodwa njengoko ii-inverters zentambo ezingenasiguquli zisanda ukusasazwa kwiiprojekthi ezinkulu zokulula kwazo i-O&M, kunye neepaneli zefilim ezincinci kwaye ngenye indlela, abanini beprojekthi ngoku kufuneka bathathele ingqalelo ukuncitshiswa kwePID.
"Kukho iindlela ezimbalwa eziphambili onokuthi ufikelele kwi-galvanic yedwa, kwaye i-transformer yenye yazo.Ukwenza olo tshintsho lungabinaguquli ngelishwa kudala lo mba, ”utshilo uMarsh."Uluhlu lwe-PV luya kugqiba ukudada, kwaye ngokuqhelekileyo oko kuthetha ukuba malunga nesiqingatha seemodyuli kuyo yonke inkqubo baya kuba necala elibi elinxulumene nomhlaba."
Iindlela ezimbalwa zingasetyenziselwa ukunceda ukuphepha i-PID kwii-inverters zentambo ezingenakuguqulwa.Abafaki bangongeza i-transformer yodwa esekelwe phantsi okanye bacolise i-step-up transformer kwicala le-AC.Kwaye abavelisi ngoku bongeza i-hardware ekhethekileyo kunye nesoftware kwii-inverters zentambo ukulwa ne-PID.
UMarsh uthe kukho iindidi ezimbini zokunciphisa i-PID kumtyaii-inverters- iindlela ezisebenzayo zokulwa ne-PID kunye neendlela zokubuyisela i-PID.I-anti-PID esebenzayo kunye nezisombululo zesoftware zithatha icala le-DC lenkqubo kwaye zinyuse amandla ombane ukuze zonke iimodyuli zibe ngaphezulu komhlaba.Ngakolunye uhlangothi, iindlela zokubuyisela i-PID zisebenza ebusuku ukuhlehlisa i-PID eqokelelwe emini.Nangona kunjalo, umenzi wefilimu encinci ye-First Solar ithi iimodyuli zayo ziphendula ngokufanelekileyo ekusebenzeni okuchasene ne-PID endaweni yokubuyisela i-PID.
Abavelisi abambalwa be-inverter kwimarike ngoku baquka i-hardware ye-anti-PID kunye ne-software ehamba kunye nokukhusela ekuthotyweni, okanye ukuthengisa izixhobo ezahlukeneyo ukwenza imisebenzi yokukhusela.Ngokomzekelo, i-CPS yaseMelika inikezela i-CPS Energy Balancer, ngelixa i-Sungrow yakha i-hardware ye-anti-PID kwi-SG125HV yayo kunye ne-SG250HX inverters yentambo.U-Sungrow waqala ukubonelela ngee-inverters ze-anti-PID malunga ne-2018.
"Kwakukho imibuzo malunga namazinga okuthotywa kweepaneli ngokubanzi ngelo xesha, ngoko ke saphuhlisa isisombululo," watsho uDaniel Friberg, umlawuli wemveliso kunye nobunjineli e-Sungrow.
I-Yaskawa Solectria isandula ukubhengeza inguqulelo echasene ne-PID ye-XGI 1500-250 yomtya wokuguqula umtya olungiselelwe ukusebenza kunye neemodyuli zefilimu yokuQala yeSolar.
"Oko kuthatha utshintsho oluncinci lwangaphakathi kwi-inverter.Ayisiyonto inkulu, kodwa ifuna ixesha lobunjineli kunye nohlaziyo loluhlu lwemodeli entsha kolu ngcelele, ke siphakathi kokungqina oko kwilebhu, utshilo uMiles Russell, umlawuli wemveliso. ulawulo eYaskawa Solectria Solar.
Zombini i-Solectria kunye ne-First Solar zenza iimveliso zabo e-United States, zinika abafakeli ukubhanqa okulula ukufezekisa iinjongo zenkuthazo zasekhaya ezibandakanyiweyo kwi-IRA.Kodwa baxoxa ngokunciphisa i-PID kakuhle ngaphambi kokuba i-IRA ibhalwe.
"Siqale obo budlelwane kwiminyaka emibini edlulileyo, kunye nenjongo nje kwinqanaba lobugcisa ukufikelela kwimveliso ehambelana ngokulula nemveliso yethu," utshilo u-Alex Kamerer, umphathi weprojekthi kwi-First Solar."Sithatha inyathelo elongezelelweyo lokuqinisekisa ukuba siyahambelana nababoneleli benkqubo yethu, enceda abathengi bethu."
Nangona abavelisi abaninzi be-inverter beqala ukubandakanya imisebenzi ye-anti-PID kwii-inverters zentambo njengoko iteknoloji isanda kusetyenziswa kwiiprojekthi ezinkulu, iinjineli ngamanye amaxesha kufuneka zigrumbe amaphepha edatha ukujonga amandla emveliso ye-anti-PID, ngokutsho kwe-Origis's Marsh.
“Sifumanisa ukuba kukho iinketho ezimbalwa phaya, kwaye ayingomqhubi omkhulu kwindleko yokuqala ye-inverter,” utshilo.“Nangona kunjalo, ezi azifane zibhengezwe kakhulu kwi-inverter, mhlawumbi ngenxa yokuba isihloko sinobugcisa kakhulu, okanye [kuba] i-PID ngokwayo inzima ukuyibona ebaleni.Ke ngokuqinisekileyo sibona ezinye ii-inverters ezingenasiguquli eziza ngaphandle kwalo msebenzi. ”
Kodwa ukunciphisa i-PID kuya kubaluleka ngakumbi njengoko iinkampani zelanga ngoku zinenketho yokuthatha irhafu yerhafu yemveliso (PTC) kwi-IRA.Ukugcina ukuthotywa kuqwalaselwe ukuze iimodyuli zivelise amandla aphezulu ixesha elide kangangoko kunokwenzeka kuya kubaluleka kwisiqinisekiso setyala lerhafu.
"Ndicinga ukuba ukuqonda ngokubanzi imboni malunga nezinto kwi-PID mhlawumbi yintoni ekufuneka inyuse - imfundo malunga namaxesha apho iimodyuli zakho zinokuthambekela kwi-PID, kunye neendlela zokubona," utshilo uMarsh.
