Introduction to Distributed Photovoltaic Power Generation

Ke kumu o ka hana mana photovoltaic :

E noho ana ka mana o ka solar photovoltaic i kahi noho koʻikoʻi i ka hoʻohana ʻana i ka ikehu o ka honua i ke kenekulia 21, ʻaʻole wale e pani i kekahi mau kumu ikehu maʻamau, akā e lilo pū i ke kino nui o ka hoʻolako ʻana i ka ikehu o ka honua.

ʻO ka ikehu hou e manaʻo ʻia e ʻoi aku ma mua o 30% o ka hui pū ʻana o ka ikehu e 2030, ʻoiai ʻo ka mana photovoltaic solar e ʻoi aku ma mua o 10% o ka lako uila holoʻokoʻa o ka honua; I ka makahiki 2040, e ʻoi aku ka nui o ka ikehu hou ma mua o 50% o ka nui o ka ikehu, a ʻo ka mana photovoltaic solar e helu ʻia ma mua o ka 20B keneta; ʻO ka ikehu hou e ʻoi aku ma mua o 80% o ka hoʻolālā ikehu, a ʻoi aku ka mana o ka lā ma mua o 60%.

Ua lawa kēia mau helu e hōʻike i nā manaʻo hoʻomohala o ka ʻoihana photovoltaic solar a me kona kūlana koʻikoʻi koʻikoʻi i ka māla ikehu.

ʻO ke kumu o ka hana mana photovoltaic:

ʻO ke kelepona Photovoltaic kahi mea semiconductor me nā hiʻohiʻona hoʻololi māmā-i-electricity, e hoʻohuli pololei ana i ka ikehu pāhawewe o ka lā i ke au pololei, a ʻo ia ka ʻāpana kumu o ka hana mana photovoltaic.

Hoʻokumu ʻia nā hiʻohiʻona uila kūikawā o nā cell photovoltaic i ka doping o kekahi mau mea (e like me ka phosphorus a i ʻole boron) i loko o ka silika crystalline.

Ma lalo o ka lā, hiki ke hana ʻia nā uku manuahi i nā semiconductor me nā waiwai uila kūikawā, Ke neʻe nei kēia mau uku manuahi a hōʻiliʻili i ke kuhikuhi ʻana, a laila e hana ana i ka mana electromotive ma nā ʻaoʻao ʻelua, a me ka hoʻoulu ʻana i ka manawa ke pani ʻia nā ʻaoʻao ʻelua me kahi conductor.

ʻO ke ʻano o ka hana mana photovoltaic :

ʻO ka ʻōnaehana hana mana photovoltaic i puʻunaue ʻia me kahi pūʻulu photovoltaic square (kahi photovoltaic square array i haku ʻia me nā modula photovoltaic i hoʻohui ʻia i ka series a me ka like), photovoltaic inverters, photovoltaic kākoʻo, photovoltaic grid-connected boxs, controller (koho), pākaukau (koho), AC a me DC nā kelepona a me nā mea e kūʻai aku ai i ka mokuʻāina. a me ka uku uku uila.

Nā pōmaikaʻi o ka hana mana photovoltaic:

1. ʻAʻole pau ka ikehu o ka lā, Eia kekahi, ua laha nui ʻia ka ikehu o ka lā ma ka honua, a hiki ke hoʻohana ʻia nā ʻōnaehana hana mana PV ma nā wahi a pau e loaʻa ai ka mālamalama, me ke kaohi ʻole ʻia e nā kumu e like me ka honua a me ke kiʻekiʻe.

2.Photovoltaic power generation 'a'ole ho'ohana i ka wahie, 'a'ole ho'oku'u i kekahi mea, e like me nā kinoea hale ho'oma'ama'a a me nā mea 'ē a'e, 'a'ohe haumia o ka ea, 'a'ohe wala'au, aloha i ke kaiapuni, 'A'ole i 'ike 'ia i nā ha'alulu i ho'okumu 'ia e nā pilikia o ka ikehu a i 'ole ka wahie market instability.

3. ʻO ka hana mana Photovoltaic me ka ʻole o nā ʻāpana hoʻoili mechanical, ʻO ka hana maʻalahi a me ka mālama ʻana, ka hana paʻa a hilinaʻi.

4. Ke hana paʻa a hilinaʻi ka ʻōnaehana photovoltaic power generation, Long service life, Crystalline silicon solar cell hiki ke lōʻihi e like me 20-35 mau makahiki.
