Isengezo: Ukuvela Kwebhokisi Le-Solar PV Junction

Amabhokisi e-Solar PV junction ahlala egcina umsebenzi ofanayo, kodwa manje njengoba amandla okukhipha amandla kanye ne-voltage yamapaneli elanga akhula, ibhokisi lokuhlanganisa ilanga kufanele lithuthukise ikhono lokuvikela amandla.

"Indima evamile yebhokisi le-junction ihlala ifana, kodwa amamojula e-PV aba namandla ngokwengeziwe," kusho uBrian Mills, uMphathi Womkhiqizo we-PV waseNyakatho Melika e-Stäubli Electrical Connectors.“Njengoba amamojula e-PV ethola umphumela ophezulu nangaphezulu, lawo ma-bypass diode kufanele enze umsebenzi owengeziwe.Indlela abamunca ngayo amandla iwukuqeda ukushisa, ngakho lokhu kushisa okuvela kuma-diode kufanele kubhekwane nakho.”

Amaswishi e-bypass apholile ashintsha ama-diode endabuko kwamanye amabhokisi okuhlangana kwe-PV ukuze kuncishiswe ukushisa okweqile okukhiqizwa ukuphuma kwemojula ye-PV ephezulu.Uma iphaneli yelanga enomthunzi ifuna ukuchitha amandla ngokwemvelo, ama-diode avamile avimbela lokho kungenzeki, kodwa akhiqize ukushisa kule nqubo.Iswishi epholile ye-bypass isebenza njengeswishi yokuvula/ukuvala, ivula isifunda lapho iphaneli yelanga izama ukumunca amandla, ivimbela ukunqwabelana kokushisa.

"Ama-Bypass diode ubuchwepheshe bama-1950s," kusho uMills.“Ziqinile futhi zithembekile, kodwa indaba yokushisa ibilokhu iwuhlupho.”Amaswishi e-cool bypass axazulula le nkinga yokushisa, kodwa abiza kakhulu kunama-diode, futhi wonke umuntu ufuna amamojula we-solar PV ashibhe ngangokunokwenzeka.

Ukuze bathole inqwaba yemali yabo, abanikazi abaningi besistimu ye-PV baphendukela kumaphaneli elanga akabili.Nakuba ugesi ukhiqizwa ngaphambili nangemuva kwephaneli yelanga, amandla asengafakwa ngebhokisi lokuhlangana.Abakhiqizi bebhokisi le-PV junction kuye kwadingeka basungule ngemiklamo yabo.

"Kuphaneli yelanga ye-bifacial, kufanele ubeke ibhokisi le-PV junction onqenqemeni lapho ungenza khona isiqiniseko sokuthi ingemuva alinawo umthunzi," kusho uRosenkranz.“Emaphethelweni, ibhokisi lokuhlangana ngeke lisaba unxande, kufanele libe lincane.”

Ukuxhumana kwe-TE kunikeza amabhokisi amathathu amancane e-SOLARLOK PV Edge junction amamojula e-PV e-bifacial, elinye ngalinye kwesokunxele, maphakathi, nangaphezulu kwesokudla semojuli, empeleni asebenza injongo efanayo njengebhokisi elikhulu elingunxande.I-Stäubli ithuthukisa ibhokisi lokuhlangana le-PV ukuze libekwe eceleni komkhawulo wamamojula anobuso obubili.

Ukuduma okusheshayo kwamamojula e-PV e-bifacial kusho ukuthi imiklamo yebhokisi le-PV junction kufanele ithuthukiswe ngesikhathi esifushane.Okunye ukubuyekezwa okungazelelwe kumasistimu elanga ahlanganisa ukuvala shaqa okusheshayo kanye nezici ezihlukahlukene zeleveli yezingxenye ezidingwa yi-National Electrical Code, namabhokisi okuhlangana kwe-PV nawo kufanele aqhubeke.

Ibhokisi le-Stäubli's PV-JB/MF multifunction junction lenziwa ngendlela oyifisayo ngefomethi evulekile, ngakho-ke lingalungela noma yiziphi izibuyekezo ezizayo, okuhlanganisa zonke izilungiseleli noma ama-micro-inverter, uma izingxenye zawo ze-elekthronikhi ziba zincane ngokwanele.

I-TE Connectivity isanda kwethula ibhokisi le-smart PV junction elihlanganisa amabhodi esekethe aphrintiwe ngokwezifiso (ama-PCB) abe yizixazululo zephaneli yelanga ngokuqapha, ukwenza kahle kanye nekhono lokuvala shaqa ngokushesha.

Abakhiqizi bebhokisi le-PV junction nabo bacabanga ukwengeza ubuchwepheshe be-inverter kumamodeli wabo wesikhathi esizayo.Amabhokisi okuhlangana anganakiwe adonsa ukunakwa okwengeziwe.
