Ko ngā pūnaha PV pūngao rā motuhake, e mōhiotia ana ko ngā pūnaha kore-pūnaha, he pūnaha whakaputa hiko motuhake i hangaia mō ngā wāhi tūmatanui kāore he urunga atu ki te whatunga hiko. Ko te whāinga o ēnei pūnaha he whakaoti i ngā take tuku hiko i ngā rohe kore-pūnaha. Ka pāngia tō rātou pono e ngā āhuatanga o te rangi, ngā tono kawenga, me ētahi atu āhuatanga. Hei whakarei ake i te pumau, ka tāpirihia he taputapu rokiroki me te whakahaere pūngao.
Te Whakarōpūtanga o ngā Pūnaha PV Rā Tūkotahi
Ko ngā pūnaha hiko pūngao rā motuhake he mea hanga mai i ngā panera rā, ngā kaiwhakahaere, me ngā pākahiko. Mō ngā kawenga AC, me whai pūngao whakawhiti. Ka taea te whakarōpū i ēnei pūnaha ki ngā momo matua e rua: ngā pūnaha hiko pūngao rā DC me ngā pūnaha hiko pūngao rā AC.
1. Ngā Pūnaha PV Rā DC
(1) Ngā Pūnaha PV Rā DC Kāore he Pūhiko
Ka whakakaha tika ēnei pūnaha i ngā kawenga DC i te awatea ina wātea te rā. Ka honoa tika ngā panera rā ki ngā kawenga, ka kore e hiahiatia he kaiwhakahaere, he rokiroki pūngao rānei. Ka whakapai ake tēnei tatūnga i te whakamahinga pūngao rā mā te karo i ngā ngaronga o te huringa me te rokiroki pūngao. Ko tētahi whakamahinga noa ko ngā papu wai e whakakahangia ana e te rā.
(2) Ngā Pūnaha PV Rā DC me ngā Pūhiko
Kei roto i ēnei pūnaha ngā panera rā, ngā kaiwhakahaere utu, ngā pākahiko, me ngā kawenga DC. I ngā wā paki, ka tukuna e ngā panera rā te pūngao ki ngā kawenga, ā, ka utua hoki ngā pākahiko i te wā kotahi. I te pō, i te wā kapua rānei, ka tukuna e ngā pākahiko te hiko ki ngā kawenga. Kei roto i ngā tono mai i ngā rama rā iti mō ngā māra rā me ngā rama marae ki ngā otinga nui mō ngā teihana waea mamao, ngā teihana whakawhiti ngaruiti, me te hiko ā-whenua. Me whakamahi ngā pūnaha nui ake i ngā huinga panera rā me ngā pēke pākahiko.
2. Ngā Pūnaha PV Rā AC
(1) Ngā Pūnaha PV Pūngao Ā-Rā AC me te Pūngao Whakaranu
Ki te whakatauritea ki ngā pūnaha DC, ka whakauruhia e ngā pūnaha AC he inverter hei huri i te DC ki te hiko AC, he mea e tika ana mō ngā kawenga AC. Ka taea e ngā pūnaha ranu te tuku hiko ki ngā kawenga AC me DC, ka whakarei ake i te whānui o te whakamahinga.
(2) Ngā Pūnaha PV Rā Tāpiri-Whatunga
Ko te nuinga o ēnei pūnaha e whakawhirinaki ana ki te pūngao o te rā mō te whakaputa hiko, me te whatunga hiko hei puna tāpiri. Ka taea te whakaiti i te rahi o ngā panera me ngā pākahiko o te rā kia pai ai te utu, mā te whakamahi i te pūngao o te rā i ngā rā paki, me te pūngao whatunga hiko i ngā wā kapua. Ka whakaitihia e tēnei huarahi ranu ngā utu haumitanga tuatahi, me te whakatutuki i ngā penapena pūngao me te whakaiti i ngā tukunga. He otinga whakawhiti whai hua tēnei mō te whakamahi i te PV o te rā i ngā rohe he neke atu i te rua hautoru ngā rā paki i ia tau.
Ngā Whakamahinga o ngā Pūnaha PV Rā Tūkotahi
He pai ngā teihana hiko pūngao rā motuhake, e mōhiotia ana ko ngā teihana hiko pūngao rā motuhake, mō ngā kāinga tūmatanui, ngā moutere, me ētahi atu wāhi kāore i te whatunga hiko e nui ana te rā me te nui o te hiahia o te kaiwhakamahi. Ko te nuinga o ēnei pūnaha mai i te maha kirowati ki te tekau kirowati te kaha. Kei roto i ēnei ko ngā rarangi panera pūngao rā, ngā pākahiko, ngā inverters, ngā pūnaha whakahaere pūngao, me ngā whatunga tohatoha hiko.
Ka utua e te pūnaha ngā pākahiko i te awatea, i a ia e tuku hiko ana ki ngā papu wai me ngā taputapu tukatuka mō ngā mahi pēnei i te rokiroki wai me te whakaputa. I te pō, ka tukuna e ngā pākahiko te pūngao mā roto i te inverter hei whakatutuki i ngā tono kawenga. He mea nui te whakahaere tika i te pākahiko, inā koa mō te whakamahinga i te pō, ngā kawenga rānei e peia ana e te motuka me te nui o te kaha e pau ana.
He otinga whai hua, he otinga pumau hoki ngā pūnaha PV pūngao rā motuhake mō te whakatika i te korenga o te hiko i ngā wāhi kāore e whakamahia ana te whatunga hiko, e whakaatu ana i tōna whakamahinga maha me tōna pūmanawa mō ngā tono whānui ake.
