Mā te hangarau rokiroki pūngao ka āwhina i ngā kaupapa photovoltaic (PV) ki te whakaiti i te whakaiti hiko, ā, ka whakarite kia whakauruhia ngā pūnaha PV ki te whatunga whānui. I roto i ngā hangarau rokiroki pūngao kua pakari me ngā hangarau arumoni o nāianei, he pai te rokiroki pūngao hikohiko hei whakauru ki ngā kaupapa PV nā te mea kāore e pāngia e ngā āhuatanga taiao, he tere te urupare, he roa hoki te ora o te huringa.
I. Pūnaha Whakaatahiko
Ko te whakaputa hiko photovoltaic, e mōhiotia ana ko te whakaputa hiko photovoltaic solar, he hangarau e huri ana i te pūngao mārama ki te pūngao hiko mā te whakamahi i te pānga photoelectric i te atanga semiconductor. E toru ngā wāhanga matua: ngā panera solar (ngā kōwae PV), ngā kaiwhakahaere, me ngā inverters.
Ka taea te wehewehe i ngā teihana hiko photovoltaic kia rua ngā wāhanga i runga i te whakaritenga o ngā wāhanga: ngā teihana hiko PV pokapū me ngā teihana hiko PV tohatoha.
Ngā Teihana Hiko PV Matua: He teihana hiko PV nui ēnei e hangaia ana i ngā wāhi whānui pēnei i ngā koraha, me te hiko e whakaputaina ana e whakauru tika ana ki te whatunga tūmatanui, ā, e hono ana ki te pūnaha tuku hiko-teitei hei tuku kawenga tawhiti. He mea noa ēnei i ngā rohe pēnei i a Qinghai, Ningxia, Gansu, me Xinjiang.
Ngā Teihana Hiko PV Tohatoha: Ka hangaia, ka whakahaerehia hoki ēnei i runga i te whenua o te kaiwhakamahi, i te taha rānei, ko te nuinga hei whakamahi māna ake me te hiko tāpiri ka tukuna ki te whatunga hiko. Ko te tikanga ka whakamahia e rātou ngā tuanui, ngā taunga waka, me ētahi atu wāhi tohatoha hei hanga teihana hiko PV, ā, he mea noa i te Tonga me te Raki o Haina. I mua, i pāngia te whanaketanga o te PV tohatoha e ngā wero nā te whakaurunga ki te whakahaere tauine. Heoi, i noho hei kaupapa wera i roto i te umanga nā te kaupapa here "whakamātautau tohatoha katoa o te rohe".
II. Ngā Tikanga Whakauru o ngā Pūnaha Rokiroki Pūngao
E rua ngā huarahi hangarau ka taea e ngā teihana hiko PV te whakamahi: te whakaurunga pokapū taha-AC me te whakaurunga tohatoha taha-DC.
Whakaurunga Pokapū taha-AC:
I tēnei huarahi, ka whakanohoia te kete pākahiko rokiroki pūngao ki waenganui i te teihana whakakaha/teihana pana o te teihana hiko. Ka hurihia te mana DC ka whakakahangia i mua i te hono atu ki te pahi AC o te teihana whakakaha, me te whakahaere i ngā whakawhiti mana i waenga i te pūnaha rokiroki pūngao me te pūnaha hiko mā te tuku. Me whirihora tēnei tikanga i ngā PCS (Pūnaha Whakawhiti Mana) maha mō te mahi whakarara me te tāpiri i ngā whakawhiti whakakaha me ngā taputapu tohatoha.
Whakaurunga Tohatoha taha-DC:
Ka tohatohahia e tēnei tikanga ngā waeine rokiroki pūngao puta noa i ngā momo huinga iti PV, me ia huinga iti he taputapu rokiroki pūngao anō kei roto, ko te nuinga he inverter PV, he transformer whakanui, he kōwae DC/DC, me te pākahiko rokiroki. I roto i tēnei kaupapa rokiroki pūngao tohatoha, ka taea e te whakawhitiwhiti kōrero i waenga i te kōwae DC/DC me te inverter PV te whakangawari i te putanga hiko, engari kāore e taea te penapena i te hiko tāpiri i te taha AC. Hei whakatutuki i te rere o te hiko e rua-ahu, me whakakapi te inverter PV kotahi-ahu ki te PCS e rua-ahu.
Mō ngā teihana hiko PV o nāianei, he iti ngā herenga o te tikanga whakauru tohatoha taha-DC nā te iti o te wāhi hei whakatakotoranga taputapu me ngā whakarerekētanga nui o ngā waea hiko, e hiahiatia ana he motu hiko roa mō te whakahou, ā, ka nui ake ngā utu.
Mā te whakamahi i ngā pūnaha rokiroki pūngao hikohiko ki ngā kaupapa PV ka whakarite i te kounga me te hototahi o te whatunga hiko o te hiko pūngao ma, ka tutuki ai ngā whakaritenga rokiroki pūngao ā-ture e ngā kamupene whatunga hiko. Ka arohia hoki te take o te whakaiti i te iti o te hiko, ā, ka whakaitihia te moumou rauemi.
