He aha te pūnaha rokiroki pūngao photovoltaic?
Ko te pūnaha rokiroki pūngao photovoltaic he huinga taputapu me te hangarau e huri ana i te pūngao o te rā hei pūngao hiko hei whakarato i ngā taputapu o te whare, me te pupuri anō i te toenga mō te whakamahi i te pō, i te kore rānei o te hiko.
He aha te mea, ā, he aha ngā wāhanga matua?
1. Mērā photovoltaic: he maha ngā mērā photovoltaic (e mōhiotia ana ko ngā panera solar) e hopu ana i te hihi o te rā, e huri ana hei iahiko tika.
2. Whatanga, taputapu me ngā taura: whakamahia hei whakatika i ngā panera rā me te kawe i te mana DC kua whakaputaina ki te inverter.
3. Ngā kaitahuri (ngā kaitahuri hono-pūnaha me ngā kaitahuri kore-pūnaha): Ka hangaia te mana aukume whakawhiti (AC) mā te huri i te mana aukume tika (DC) e whakaputaina ana e ngā panera rā, ā, ka rongoatia te mana taikaha ki roto i tētahi pūnaha rokiroki pūngao, ka taea hoki te hono atu ki te pūnahi tāone.
4. Ngā taputapu rokiroki pūngao: Ko te tikanga e pā ana ki ngā pākahiko, pērā i ngā pākahiko lithium me ētahi atu momo pākahiko, e penapena ana i te hiko i hangaia e te pūngao o te rā kāore e whakamahia tonutia mā te inverter hei whakamahi i muri mai.
5. EMS me te BMS: Ko te EMS te pūnaha e aroturuki ana, e whakahaere ana hoki i te mahi a te pūnaha katoa kia pai ai te mahi me te haumaru o ngā wāhanga katoa. Ko te BMS te pūnaha whakahaere o te pākahiko rokiroki, e arotau ana, e whakahaere ana hoki i te utu me te tukunga o te pākahiko.
6. Pouaka whakakotahitanga: tae atu ki ngā momo taputapu tiaki me ngā pana katoa, pērā i te tiaki ngaru (tiaki uira) i waenganui o te inverter urunga rā, ngā fiusi, ngā whati ara iahiko DC, ngā whati ara iahiko whakauru whaipainga, ngā whati ara iahiko putanga tuku hiko korekore me ētahi atu.
Te pānga photovoltaic, me pēhea te tiki hiko mai i te pūngao o te rā
1. Te mimiti o ngā photon: Ina pā te rā (tae atu ki ētahi atu pūtake mārama) ki te rauemi (silicon) o te panera rā, ka mimitihia te kaha o ngā photon e te rauemi semiconductor.
2. Te whakaohooho i ngā irahiko: Mā te pūngao photon kua mimitihia ka peke ngā irahiko i roto i te haurua-ā-ira mai i te awhi valence ki te awhi kawe, ka huri i a rātou mai i te āhua here ki te āhua kore utu.
3. Te whakaputanga o ngā takirua irahiko-pōha: Ina whakaohokia te irahiko ki roto i te awhi arataki, ka waiho he kōhao i roto i te awhi valence. Ka hangaia e tēnei irahiko me te kōhao he takirua irahiko-pōhao.
4. Te whakatū i tētahi mara hiko: Kei roto i ngā rauemi photovoltaic ngā rohe momo-P me te momo-N, ā, i te hononga o ēnei rohe e rua (arā, te hononga PN), ka hangaia he mara hiko ā-roto.
5. Te whakahaere i te rere o ngā irahiko: Ka akiakihia e tēnei papa hiko ā-roto ngā irahiko kore utu kia neke ki te rohe momo-N me ngā kōhao kia neke ki te rohe momo-P, ā, ka hangaia he iahiko e tēnei nekehanga.
6. Te kohikohi i te iahiko: Mā te inverter, ka hurihia tēnei iahiko hei hiko AC, DC rānei, ka rongoatia ki te pūnaha rokiroki pūngao mō te whakamahinga i muri mai.
Te mahi a ngā kaitahuri hono-pūnaha me ngā kaitahuri kore-pūnaha me ō rātou momo mahi
1. Ka hurihia e te kaitahuri hono-pūnaha te mana DC i hangaia e ngā panera rā ki te ngaohiko pahi e tika ana mō te kaitahuri mā te kōwae MPPT, kātahi ka hurihia hei mana AC mā ngā wāhanga hiko hei tuku taputapu whare, ā, ki te nui te mana, ka hurihia ki te ngaohiko ōrite ki te pūnaha rokiroki ka utua ki te pūnaha rokiroki hei tārua, ā, ki te nui te mana, ka hurihia ka whakauruhia ki te pūnahi hiko.
2. Kei ngā pūnaha rokiroki pūngao PV ngā aratau whakaputa-ake me te whakapau-ake, ngā aratau heu-piki me te whakakī-awaawa, me ngā aratau matua-pūhiko.
Aratau whakaputa-ā-koe me te whakamahi-ā-koe: ka hurihia te hiko e hangaia ana e ngā panera rā hei iahiko whakawhiti (AC) ka tukuna tika ki ngā taputapu o te whare, ko te toenga ka utaina ki te pūnaha rokiroki; ki te kore e ranea te iahiko e hangaia ana e ngā panera rā hei whakamahi mā ngā taputapu o te whare, ka whakakīia anō mā te whakamahi i te whatunga hiko o te tāone.
Aratau Heu Tihi me te Whakakī Awaawa: I te wā iti kua whakaritea, ka hurihia te mana AC mai i te whatunga tāone hei mana DC ka utaina ki te pūnaha rokiroki pūngao; i te wā tihi kua whakaritea, ka hurihia te mana DC i roto i te pūnaha rokiroki pūngao hei mana AC hei tuku ki ngā taputapu whare; ki te kore e ranea te mana pākahiko, ka tāpirihia e te whatunga tāone.
Aratau Matua Pūhiko: Ahakoa te āhua o te āhuatanga, me whakarite tuatahi kei te kī tonu te mana o te pūnaha rokiroki hiko. Ina whakaputahia he hiko nui ake e te pūngao o te rā, ka hurihia tika hei hiko AC mō te whakamahi pākahiko kāinga, ā, ina whakakāhia te mahi hononga whatunga, ka tāpirihia te toenga ki te whatunga tāone.
Me pēhea te hoahoa me te tatau i te maha o ngā panera rā W hei tāuta
Paewhiri rā: LESSO 550W
Rahi: L 2278 x 1134mm tata ki te 2.6 putu tapawha.
Taumaha: 28kg
Mana: 550W
Tātai tātai horahanga:
Tuhipoka: Tautokohia ngā panera rā i raro i te 7KW
Te mana katoa o te papa rā: 550W * 12 = 6.6KW
Te horahanga o te tuanui e hiahiatia ana: 12 x 2.6 putu tapawha = 31.2 putu tapawha.
Te tātaitanga o te whakaputa hiko o ia rā:
Hei tauira, ko Wenzhou, Haina, ko te rā tino pai ko te 3.77 hāora, ko te whakaputa hiko mō ia watt i te tau ko te 1.088KWH, ko te whakamahinga whai hua o ia tau ko te 1087.08 hāora. Koki tāutanga: 18 nekehanga.
Te whakaputa hiko tino kaha o ia rā = 6.6KW x 3.77H = 24.88KWH
Te whakaputa hiko ā-tau = 6.6KW x 1087.08H = 7174.728KWH
