Kedu ihe bụ sistemụ nchekwa ike fotovoltaic?
Sistemụ nchekwa ike fotovoltaic bụ ngwakọta nke akụrụngwa na teknụzụ nke na-agbanwe ike anyanwụ ka ọ bụrụ ike eletriki iji nye ngwa ụlọ ebe a na-echekwa ihe fọdụrụ maka ojiji n'abalị ma ọ bụ na enweghị ike ọrụ.
Gịnị bụ ya, kedukwa ihe ndị bụ isi mejupụtara ya?
1. Modulu fotovoltaic: nwere ọtụtụ modulu fotovoltaic (a makwaara dị ka panel anyanwụ) nke na-ahụ maka ijide ìhè anyanwụ ma gbanwee ya ka ọ bụrụ ọkụ kpọmkwem.
2. Ebe a na-adọba ụgbọala, ihe mgbakwunye na eriri: eji arụ ọrụ iji dozie panel anyanwụ ma bufee ike DC emepụtara na inverter.
3. Inverters (njikọ grid na nke na-anaghị ejikọta grid): A na-emepụta ike mgbanwe (AC) site na ịtụgharị ike kpọmkwem (DC) nke panel anyanwụ na-emepụta, ma chekwaa ike karịrị akarị na sistemụ nchekwa ike, nke enwere ike ijikọ na grid obodo.
4. Ngwaọrụ nchekwa ike: A na-ezo aka na batrị, dịka batrị lithium na ụdị batrị ndị ọzọ, nke na-echekwa ọkụ eletrik nke ike anyanwụ na-emepụta nke a na-ejighị ya ozugbo site na inverter maka ojiji ọzọ.
5. EMS na BMS: EMS bụ sistemụ nke na-enyocha ma na-achịkwa ọrụ nke sistemụ ahụ dum iji hụ na akụkụ niile na-arụ ọrụ nke ọma na n'enweghị nsogbu. BMS bụ sistemụ njikwa nke batrị nchekwa, na-emeziwanye ma na-achịkwa chaja na mwepụ nke batrị ahụ.
6. Igbe njikọta: gụnyere ụdị ngwa nchekwa na swiitị niile, dịka nchekwa mmụba (mkpuchi àmụ̀mà) n'etiti inverter ohere anyanwụ, fuse, ihe mgbawa sekit DC, ihe mgbawa sekit ntinye ọrụ, ihe mgbawa sekit mmepụta nke na-anaghị akwụsị akwụsị na ihe ndị ọzọ.
Mmetụta fotovoltaic, otu esi enweta ọkụ eletrik site na ike anyanwụ
1. Mmịpụta nke foton: Mgbe ìhè anyanwụ (gụnyere isi iyi ọkụ ndị ọzọ) rutere ihe (silikọn) nke panel anyanwụ, ihe semiconductor na-amịkọrọ ike nke foton.
2. Mkpali nke elektrọn: Ike foton a na-amịkọrọ na-eme ka elektrọn dị na semiconductor wụlie elu site na eriri valence gaa na eriri conduction, na-agbanwe ha site na steeti ejiri aka kee gaa na steeti nwere onwe.
3. Mmepụta nke ụzọ abụọ nke oghere elektrọn: Mgbe elektrọn na-akpali akpali n'ime eriri conduction, ọ na-ahapụ oghere n'ime eriri valence. Elektrọn na oghere a na-etolite ụzọ abụọ nke oghere elektrọn.
4. Ịmepụta ebe ọkụ eletrik: Mpaghara ụdị P na ụdị N na-adịkarị na ihe ọkụ eletrik, na njikọ nke mpaghara abụọ a (ya bụ, njikọ PN), a na-emepụta ebe ọkụ eletrik dị n'ime.
5. Na-akpali usoro elektrọn: Ọdụ eletrik dị n'ime a na-akpali elektrọn ndị a na-enweghị ihe ọ bụla ịga n'akụkụ ụdị N na oghere ndị ahụ iji gaa n'akụkụ ụdị P, mmegharị a na-emepụtakwa ọkụ eletrik.
6. Ịnakọta ọkụ eletrik: Site na inverter, a na-agbanwe ọkụ eletrik a ka ọ bụrụ ọkụ eletrik AC ma ọ bụ DC ma chekwaa ya na sistemụ nchekwa ike maka ojiji ọzọ.
Otu inverters ejikọrọ na grid na-arụ ọrụ na ụzọ ha si arụ ọrụ
1. Inverter ejikọrọ na grid na-agbanwe ike DC nke panel anyanwụ na-emepụta ka ọ bụrụ voltaji bọs kwesịrị ekwesị maka inverter site na modulu MPPT, wee gbanwee ya ka ọ bụrụ ike AC site na ihe eletrọnịkị iji nye ngwa ụlọ, ọ bụrụkwa na enwere ike karịrị akarị, a ga-agbanwe ya ka ọ bụrụ otu voltaji ahụ dị ka nke sistemụ nchekwa ma chajịa ya na sistemụ nchekwa maka nkwado ndabere, ọ bụrụkwa na enwere ike karịrị akarị, a ga-atụgharị ya ma tinye ya na grid ike.
2. Sistemụ nchekwa ike PV nwere ụdị mmepụta onwe onye na nke oriri onwe onye, ụdị ịkpụcha elu na ụdị ijupụta ndagwurugwu, yana ụdị nchekwa batrị.
Nhazi onwe na iji onwe onye: a na-agbanwe ọkụ eletrik nke panel anyanwụ na-emepụta ka ọ bụrụ ọkụ eletrik alternating (AC) ma nye ya ozugbo na ngwa ụlọ, ebe a na-etinye ihe karịrị ya na sistemụ nchekwa; ọ bụrụ na ọkụ eletrik nke panel anyanwụ na-emepụta ezughị iji ngwa ụlọ, a na-eji grid ike obodo eme ihe.
Ụdị Ịkpụcha Elu na Njupụta Ndagwurugwu: N'oge a kara aka, a ga-agbanwe ike AC sitere na grid obodo ka ọ bụrụ ike DC ma chajịa ya na sistemụ nchekwa ike; n'oge a kara aka, a ga-agbanwe ike DC dị na sistemụ nchekwa ike ka ọ bụrụ ike AC ka e wee nye ya ngwa ụlọ; ọ bụrụ na ike batrị ezughi oke, grid obodo ga-agbakwunye ya.
Ụdị Nkwanye Elu Batrị: N'agbanyeghị ihe ọ dị, buru ụzọ hụ na ike nke sistemụ nchekwa ike zuru oke, mgbe ike anyanwụ na-emepụta ike karịa, a ga-agbanwe ya ozugbo ka ọ bụrụ ike AC maka iji batrị n'ụlọ, mgbe agbanyere ọrụ njikọ grid, a ga-agbakwunye ihe karịrị na grid obodo.
Otu esi emepụta ma gbakọọ ọnụọgụ panel anyanwụ W ị ga-etinye
Ogwe anyanwụ: LESSO 550W
Nha: L 2278 x 1134mm ihe dị ka 2.6 sq. ft.
Ibu: 28kg
Ike: 550W
Usoro ngụkọ mpaghara:
Rịba ama: Kwado panel anyanwụ dị n'okpuru 7KW
Ike zuru oke nke panel anyanwụ: 550W*12=6.6KW
Ebe elu ụlọ dị mkpa: 12 x 2.6 sq. ft. = 31.2 sq. ft.
Ngụkọta mmepụta ike kwa ụbọchị:
Were Wenzhou, China dịka ọmụmaatụ, oke anwụ na-acha awa 3.77, kwa watt kwa afọ mmepụta ike 1.088KWH, ojiji dị irè kwa afọ awa 1087.08 Akụkụ ntinye: ogo 18
Ike kachasị elu kwa ụbọchị = 6.6KW x 3.77H = 24.88KWH
Mmepụta ike kwa afọ = 6.6KW x 1087.08H = 7174.728KWH
