He aha ka manaʻo ke lohe ʻoe e pili ana i ka ʻenehana pākaukau BC?
No nā mea he nui, "kiʻekiʻe kiʻekiʻe a me ka mana kiʻekiʻe" nā manaʻo mua. ʻOiaʻiʻo i kēia, ke kaena nei nā mea BC i ka hana hoʻololi kiʻekiʻe loa ma waena o nā ʻāpana pili kilika a pau, me ka hoʻonohonoho ʻana i nā moʻolelo honua. Eia nō naʻe, ʻike pū ʻia nā hopohopo e like me ka "haʻahaʻa bifacial ratio". Manaʻo ka ʻoihana i nā ʻāpana BC ʻoi aku ka maikaʻi akā me ka ratio bifacial haʻahaʻa, ʻoi aku ka maikaʻi no ka hoʻokumu ʻana i ka mana unilateral, e hoʻohilahila ai i kekahi mau papahana no ka makaʻu e hōʻemi i ka hana mana holoʻokoʻa.
Eia naʻe, he mea nui e ʻike i nā holomua koʻikoʻi. ʻO ka mea mua, ua hiki i ka hoʻomaikaʻi ʻana i ka ʻenehana kaʻina hana i hiki i nā ʻāpana pākaukau BC ke hoʻokō i nā ratio hope o 60% a ʻoi aku paha, e pani ana i ke āpau me nā ʻenehana ʻē aʻe. Eia kekahi, ʻaʻole ʻike nā papahana photovoltaic āpau ma mua o ka piʻi ʻana o 15% o ka hanauna hope; ʻike ka nui ma lalo o 5%, emi ka hopena ma mua o ka manaʻo. ʻOiai ka mana haʻahaʻa haʻahaʻa hope, ʻoi aku ka nui o nā loaʻa ma mua-sidepower ma mua o ka uku. No nā hale i like ka nui, hiki i nā ʻāpana pākaukau ʻelua ʻaoʻao BC ke hoʻonui i ka uila. Manaʻo ka poʻe loea o ka ʻoihana e nānā hou aku i nā pilikia e like me ka hoʻohaʻahaʻa ʻana i ka mana, ka pōʻino, a me ka hōʻiliʻili ʻana o ka lepo ma luna o nā ʻili, hiki ke hoʻopilikia nui i ka hana mana.
Ma ka China (Shandong) New Energy and Energy Storage Application Expo, ua hana ko Longi Green Energy i ka hopena koʻikoʻi me ka hoʻokuʻu ʻia ʻana o kāna mau modula aniani pālua Hi-MO X6 i hoʻolālā ʻia e kū i ka haʻahaʻa a me ka wela, e hāʻawi ana i nā koho hou aʻe i ka mākeke a hoʻonui. hiki i nā ʻōnaehana photovoltaic ke hoʻololi i nā aniau paʻakikī. ʻO Niu Yanyan, ka pelekikena o Longi Green Energy's Distributed Business ma Kina, ua hoʻokūpaʻa i ka manaʻo o ka hui e hōʻemi i nā pilikia kūpono no nā mea kūʻai aku, no ka mea, he waiwai nui nā hoʻokomo photovoltaic. ʻO nā pilikia e pili ana me nā wahi haʻahaʻa a me ka wela, i hoʻohaʻahaʻa pinepine ʻia, hiki ke alakaʻi i ka electrode corrosion i nā modula ma lalo o ke kiʻekiʻe o ka mahana a me ka haʻahaʻa, e hoʻoulu ai i ka PID attenuation a hoʻopilikia i ka mana o ke ola o nā modules.
Hōʻike ka ʻikepili a ka National Energy Administration e like me ka hopena o 2023, ua hōʻea ka kumulative photovoltaic installations ma Kina ma kahi o 609GW, me kahi kokoke i 60% aia ma kahakai, kokoke i ke kai, a i ʻole nā wahi humid e like me Kina Hema a me Kina Hema. I nā hiʻohiʻona i hoʻokaʻawale ʻia, ʻo ka hoʻokomo ʻana i nā wahi humid a hiki i ka 77.6%. ʻO ka nānā ʻole ʻana i ka pale ʻana o nā modules i ka haʻahaʻa a me ka wela, e ʻae ana i ka mahu wai a me ka noe paʻakai e hoʻopau iā lākou, hiki ke hoʻohaʻahaʻa loa i ka hana ʻana o nā modula photovoltaic i nā makahiki, e hōʻemi ana i nā hoʻihoʻi i manaʻo ʻia o nā mea hoʻopukapuka. No ka hoʻoponopono ʻana i kēia pilikia ʻoihana, ua hoʻomohala ʻo Longi i ka hi-MO X6 pālua-aniani humidity a me ka wela-pale modules, e hoʻokō i kahi holomua piha mai ka hoʻokumu ʻana o ke kelepona a hiki i ka hoʻopili ʻana, e hōʻoiaʻiʻo ana i ka hana pono a me ka hilinaʻi ʻana i nā kūlana haʻahaʻa a wela, e like me ka Niu. ʻO Yanyan.
Kūʻē nā modula aniani pālua Hi-MO X6 no ko lākou kūpaʻa maikaʻi ʻana i nā kūlana o ka wā. ʻO ka mea uila uila HPBC, me ka ʻole o ke alumini kala-aluminika, ʻoi aku ka liʻiliʻi i nā hopena electrochemical. Hoʻohui ʻia, hoʻohana nā modules i kahi ʻenehana kiʻiʻoniʻoni POE ʻaoʻao ʻelua, hāʻawi ʻehiku mau manawa i ka pale ʻana o ka makū o EVA, a hoʻohana i ke kolu hoʻopaʻa paʻa kiʻekiʻe no ka hoʻopili ʻana, me ka pale ʻana i ka wai.
Ua hōʻike ʻia nā hopena hōʻike mai ka hui ʻekolu ʻaoʻao DH1000 ma lalo o nā kūlana o 85°ʻO ka mahana a me ka 85% humidity, ʻo 0.89% wale nō ka attenuation o nā modules, ʻoi loa ma lalo o ka IEC (International Electrotechnical Commission) 5% ʻoihana maʻamau. He haʻahaʻa haʻahaʻa loa nā hopena hoʻokolohua PID ma 1.26%, ʻoi aku ka maikaʻi ma mua o nā huahana ʻoihana like. Ua ʻōlelo ʻo Longi e alakaʻi ana nā modules Hi-MO X6 i ka ʻoihana ma ke ʻano o ka attenuation, me 1% wale nō ka hoʻohaʻahaʻa ʻana i ka makahiki mua a me ka helu degradation linear o 0.35% wale nō. Me kahi palapala mana mana 30-makahiki, ua hoʻopaʻa ʻia nā modula e mālama ma luna o 88.85% o ko lākou mana hoʻopuka ma hope o 30 mau makahiki, e pōmaikaʻi ana mai kahi coefficient mahana wela o -0.28%.
No ka hōʻike ʻana i ke kūʻē ʻana o nā modules i ka haʻahaʻa a me ka wela, ua hoʻokomo ʻia nā limahana Longi i kekahi ʻaoʻao o kahi module i loko o ka wai wela ma luna o 60°C i ka wā hōʻike. ʻAʻohe hopena o ka ʻikepili hana, e hōʻike ana i ka ikaika o ka huahana e kūʻē i ka haʻahaʻa a me ka wela me kahi ala pololei. Ua ʻōlelo ʻo Lv Yuan, ka pelekikena o Longi Green Energy Distributed Business Product and Solutions Center, ʻo ka hilinaʻi ka waiwai nui o Longi, ʻo ia ka mea ma mua o nā mea āpau. ʻOiai ʻo ka ʻoihana e hoʻemi wikiwiki i nā kumu kūʻai, mālama ʻo Longi i nā kūlana kiʻekiʻe ma ka mānoanoa wafer silicon, aniani, a me ka maikaʻi o ke kiʻi, e hōʻole ana i ka hoʻololi ʻana i ka palekana no ka hoʻokūkū kumukūʻai.
Ua hōʻike hou aku ʻo Niu Yanyan i ka manaʻo o Longi e kālele ana i ka maikaʻi o ka huahana a me ka lawelawe ma luna o nā kaua kumukūʻai, me ka manaʻoʻiʻo i ka hāʻawi ʻana i ka waiwai i nā mea kūʻai aku. Ua manaʻoʻiʻo ʻo ia e ʻike nā mea kūʻai aku, e helu pono i ka hoʻihoʻi ʻana, e ʻike i ka waiwai i hoʻohui ʻia: hiki ke kūʻai ʻia nā huahana a Longi i 1% kiʻekiʻe, akā hiki ke piʻi i ka loaʻa kālā o ka uila i 10%, kahi helu e mahalo ʻia e kekahi mea hoʻopukapuka.
Ua wānana ʻo Sobey Consulting e hiki i ka makahiki 2024, e hōʻea ana nā mea hoʻokomo photovoltaic i hāʻawi ʻia ma waena o 90-100GW, me kahi mākeke ākea ākea ma waho. ʻO ka Hi-MO X6 pālua-aniani humidity a me ka wela wela, e hāʻawi ana i ka ʻoi aku ka maikaʻi, ka mana, a me ka hoʻohaʻahaʻa haʻahaʻa, e hōʻike i kahi koho maikaʻi no ka ulu ʻana o ka hoʻokūkū ma ka mākeke māhele.
