Empirical Data: TOPCon, nui nui modules, string inverters, a flat one-axis trackers hoʻoikaika pono i ka mana o ka ʻōnaehana!

E hoʻomaka ana mai 2022, ua loaʻa ka nui o nā ʻenehana n-type a me nā ʻenehana module mai nā ʻoihana hoʻopukapuka mana, me ka piʻi mau ʻana o kā lākou mākeke. I ka makahiki 2023, e like me nā helu mai Sobey Consulting, ʻoi aku ka nui o ke kūʻai ʻana o nā ʻenehana n-type i ka hapa nui o nā ʻoihana photovoltaic alakaʻi ma mua o 30%, me kekahi mau ʻoihana i ʻoi aku ma mua o 60%. Eia kekahi, ʻaʻole liʻiliʻi ma mua o 15 mau ʻoihana photovoltaic i hoʻonohonoho pono i ka pahuhopu o "ʻoi aku ma mua o ka 60% kūʻai kūʻai no nā huahana n-type e 2024".

Ma ke ʻano o nā ala ʻenehana, ʻo ka koho no ka hapa nui o nā ʻoihana he n-type TOPCon, ʻoiai ua koho kekahi i nā n-type HJT a i ʻole BC ʻenehana ʻenehana. ʻO wai ka ʻenehana ʻenehana a me ke ʻano o ka hui pū ʻana e hiki ke lawe mai i ka pono o ka hana mana kiʻekiʻe, ʻoi aku ka mana o ka mana, a me nā kumukūʻai uila haʻahaʻa? ʻAʻole pili kēia i nā hoʻoholo hoʻokele waiwai o nā ʻoihana akā pili pū kekahi i nā koho o nā ʻoihana hoʻopukapuka mana i ka wā o ke kaʻina koho.

Ma Malaki 28, ua hoʻokuʻu ka National Photovoltaic and Energy Storage Demonstration Platform (Daqing Base) i nā hopena ʻikepili no ka makahiki 2023, me ka manaʻo e hōʻike i ka hana o nā mea like ʻole, nā hale, a me nā huahana ʻenehana ma lalo o nā kaiapuni hana maoli. Hāʻawi kēia i ke kākoʻo ʻikepili a me ke alakaʻi ʻana i ka ʻoihana no ka hoʻolaha ʻana a me ka hoʻohana ʻana i nā ʻenehana hou, nā huahana hou, a me nā mea hou, no laila e hoʻomaʻamaʻa i ka hoʻololi ʻana a me ka hoʻonui ʻana i nā huahana.

Ua kuhikuhi ʻo Xie Xiaoping, ka luna o ke komite hoʻonaʻauao o ke kahua, i ka hōʻike:

ʻO nā ʻano meteorological a me ka irradiation:

ʻOi aku ka haʻahaʻa o ka irradiation ma 2023 ma mua o ka manawa like i ka makahiki 2022, me nā ʻaoʻao ākea a me nā ʻaoʻao inclined (45 °) e ʻike ana i ka emi ʻana o 4%; ʻOi aku ka lōʻihi o ka manawa hana makahiki ma lalo o ka haʻahaʻa haʻahaʻa, me nā hana ma lalo o 400W/m² he 53% o ka manawa; ʻO ka hoʻomālamalama ʻana i ka ʻaoʻao hope o ka makahiki he 19%, a ʻo ka irradiation hope (45°) he 14%, ʻo ia ka mea like me 2022.

ʻAno module:

ʻIkepili Kūikawā

n-type high-efficiency modules i oi aku ka mana o ka mana, e like me ke au i ka makahiki 2022. Ma ke ano o ka hana mana no ka megawatt, TOPCon a me IBC he 2.87% a me ka 1.71% kiekie mamua o PERC; ʻO nā modula nui-nui loaʻa ka mana o ka mana, me ka ʻokoʻa nui loa o ka hana mana ma kahi o 2.8%; aia nā ʻokoʻa i ka mana maikaʻi o ke kaʻina hana module ma waena o nā mea hana, e alakaʻi ana i nā ʻokoʻa nui i ka hana mana o nā modules. ʻO ka ʻokoʻa o ka mana ma waena o ka ʻenehana like mai nā mea hana like ʻole hiki ke like me 1.63%; ʻO ka hapa nui o nā kumukūʻai hoʻohaʻahaʻa i hoʻokō i ka "Specifications for the Photovoltaic Manufacturing Industry (2021 Edition)", akā ua ʻoi aku kekahi i nā koi maʻamau; ua emi iho ka helu degradation o n-type high-efficiency modules, me TOPCon degrading ma waena o 1.57-2.51%, IBC degrading ma waena o 0.89-1.35%, PERC degrading ma waena o 1.54-4.01%, a me HJT degrading a hiki i 8.82% ma muli o ka instability o ka ʻenehana amorphous.

ʻAno Inverter:

Ua kūlike nā mana o ka mana o nā mea hoʻohuli ʻenehana like ʻole i nā makahiki ʻelua i hala iho nei, me nā mea hoʻohuli kaula e hoʻohua i ka mana kiʻekiʻe loa, ʻo ia ka 1.04% a me 2.33% kiʻekiʻe ma mua o nā inverters kikowaena a puʻunaue ʻia, kēlā me kēia; ʻO ka pono maoli o nā ʻenehana like ʻole a me nā mea hoʻohuli mea hana ma kahi o 98.45%, me ka IGBT home a me nā mea hoʻohuli IGBT i lawe ʻia me ka ʻokoʻa kūpono o loko o 0.01% ma lalo o nā ukana like ʻole.

ʻAno kākoʻo:

Loaʻa i nā kākoʻo hoʻokolo ka mana kūpono loa. Hoʻohālikelike ʻia i nā kākoʻo paʻa, kākoʻo ka ʻimi ʻana i nā axis ʻelua i ka hoʻonui ʻia ʻana o ka mana e 26.52%, kākoʻo kū hoʻokahi-axis i kākoʻo ʻia e 19.37%, kākoʻo i ka axis hoʻokahi e 19.36%, paʻa hoʻokahi-axis (me ka 10 ° tilt) e 15.77%, nā kākoʻo omni-directional e 12.26%, a me nā kākoʻo hiki ke hoʻoponopono ʻia e 4.41%. ʻO ka hana mana o nā ʻano kākoʻo like ʻole i hoʻopilikia nui ʻia e ke kau.

ʻAno ʻōnaehana Photovoltaic:

ʻO nā ʻano hoʻolālā hoʻolālā ʻekolu me ka mana kiʻekiʻe loa, ʻo ia nā trackers dual-axis + bifacial modules + string inverters, flat single-axis (me ka 10 ° tilt) kākoʻo + bifacial modules + string inverters, a me nā kākoʻo inclined single-axis + modules bifacial + mea hoʻohuli kaula.

Ma muli o nā hopena ʻikepili ma luna, ua hana ʻo Xie Xiaoping i kekahi mau manaʻo, me ka hoʻomaikaʻi ʻana i ka pololei o ka wanana mana photovoltaic, ka hoʻonui ʻana i ka helu o nā modules i kahi kaula e hoʻonui ai i ka hana ʻana o nā mea hana, e hoʻolaha ana i nā trackers pākahi pākahi me ka tilt i ke anuanu kiʻekiʻe-latitude. nā ʻāpana wela, ka hoʻomaikaʻi ʻana i nā mea hoʻopaʻa a me nā kaʻina hana o nā pūnae Heterojunction, e hoʻonui ana i nā ʻāpana helu no ka hana mana o ka ʻōnaehana bifacial module, a me ka hoʻomaikaʻi ʻana i ka hoʻolālā a me nā hoʻolālā hana o nā keʻena mālama photovoltaic.

Ua hoʻolauna ʻia ua hoʻolālā ka National Photovoltaic and Energy Storage Demonstration Platform (Daqing Base) ma kahi o 640 mau papahana hoʻokolohua i ka wā "Hoʻolālā ʻumikumamāhā ʻelima makahiki", me ka liʻiliʻi o 100 mau papahana i kēlā me kēia makahiki, e unuhi ana i kahi pālākiō ma kahi o 1050MW. Ua kūkulu piha ʻia ka papa ʻelua o ka waihona ma Iune 2023, me nā hoʻolālā no ka mana hana piha i Malaki 2024, a ua hoʻomaka ke kolu o ke kūkulu ʻana i ʻAukake 2023, me ka hoʻopau ʻana o ke kahua paʻa a me ka mana hana piha i hoʻolālā ʻia e ka hopena o 2024.
