He Akoranga Take mō tētahi Otinga Pūnaha Ranu Hau 140kW i te UK

Te Papamuri me ngā Whakaritenga a te Kaihoko:

Nō te UK te kiritaki, ā, ko ia te rangatira o tētahi kamupene tāonga whare. He nui rawa te hiko e pau ana i tana wheketere, e 300 kwh te hiko e pau ana i ia rā. I tēnei wā, kua whai pūnaha papa rā 40kw te kiritaki e hono ana ki te whatunga hiko, engari e mārama ana kāore e taea e tēnei te whakatutuki i te hiahia hiko a te kiritaki. Ko te whakaaro o nāianei o te kiritaki ko te tāuta i ngā tāhū hau, ngā papa rā, me ngā pākahiko rokiroki hiko hei hanga i tētahi pūnaha ranu hau, ka taea te whakaputa hiko-ā-koe me te whakamahi-ā-koe mō te nuinga o te wā. Ahakoa i ngā wā ua roa, ka taea hoki te whakamahi i te hiko whatunga hiko i te pō mō te hiko iti ake te utu me te tuku hiko i te awatea.

Tuhituhi

Tuatahi, i tirohia e mātou te tere o te hau o te kiritaki i te teitei o te 15 mita. Ko te tere hau toharite o te kiritaki he 6.5 m/s, he tino pai mō ngā tāpine hau. Ko te tikanga o tēnei ka taea e mātou te whakahaere i te mana katoa. Nō reira, ka tūtohu mātou kia whakamahia he pūnaha hau ranu pūngao rā. Ko te 20kW Tāwhana hau DK e matapaetia ana ka whakaputahia e ia neke atu i te 150 kWh ia rā. Mā te whakatau tata, ko te pūnaha whakaputa hiko 40kw o nāianei o te kiritaki e whakaputa ana i te 35000kwh o te hiko ia tau. Nō reira, ko te whakaputa hiko o ia rā he tata ki te 95kwh. He aha i iti ai? Nā te mea i te UK, ka ua mō te 150 rā ia tau, ā, kāore e ranea te whakaputa hiko o ia rā. Nō reira, me matapakihia tēnei āhuatanga. Mēnā he tāwhana hau 20kw kei te wātea, ā, he nui te hihi o te rā, i roto i te wā mahi 8-hāora i te awatea, e matapaetia ana ka whakaratohia e te tāwhana hau me ngā panera rā 40kw te 170kwh o te kaha. Ka taea te tiki i te toenga o te 130kwh o te āputa kaha mai i ngā pākahiko, i te whatunga hiko rānei. Mēnā ka ua, kāore e taea e ngā panera rā 40kw te whakarato kaha. Ka taea e te tāwhana hau te whakarato i te 40kwh o te kaha i roto i te 8 hāora, nō reira me tiki tonu te 260kwh o te kaha mai i ngā pākahiko, i te whatunga hiko rānei. Mena he āhuatanga motuhake o te ua me te kore hau, ka puta katoa te 300kwh o te pūngao mai i ngā pākahiko, i te whatunga hiko rānei.

I te mea ko te hohonutanga o te tukunga o te pākahiko pēhanga-teitei he 95%, me 315 kWh te iti rawa o te kaha o te pākahiko. Kua whakamahere kē te kaihoko ki te hoko i ngā huinga pākahiko lithium 240 kWh e rua, nō reira he rawaka tēnei kaha o te pākahiko. Kātahi ka tatauhia me pēhea te utu katoa i te pākahiko 480 kWh i raro i te tikanga he rā te rā, ā, me whakaiti i te tūponotanga o te hoko hiko mai i te whatunga hiko i te nui e taea ana. Ko te kaha e whakaputaina ana e te tāhū hau i roto i ngā hāora 24 he tata ki te 150 kWh. Nō reira, kei te toe tonu te 330 kWh o te wāhi. Mā te tāpiri i te 300 kWh e pau ana i roto i ngā hāora 8, me 120 kW o ngā panera rā te iti rawa, nō reira me 80 kW anō hoki o ngā panera rā.

Ko te toharite o te hiko e pau ana i te kiritaki i ia rā he 8 hāora me te 300 kWh. Ina whakaarohia ngā āhuatanga pēnei i ngā kawenga hiko, me nui ake te mana o te inverter i te 60 kW.

Whakautu

I muri i te tātaritanga i runga ake nei, ko tā mātou mahere tuatahi he whakamahi i te 140kw hokomo where raaki he tāwhana hau DK 20kw, me ngā panera rā 120kw, ngā pākahiko 240kw e rua, me te inverter S6-EH3P(75-125)K10-NV-YD-H a Solis. E 10 ngā tauranga tāuru MPPT o tēnei inverter, ā, ka taea e te tauranga tāuru kotahi te whakahaere i te tāuru DC 20kw. Nō reira, ka taea hoki te hono tika i tā mātou kaiwhakahaere tāwhana hau ki tēnei inverter.

I tino whakaae te kiritaki ki tēnei otinga mō te pūnaha hau ranu 140kw. Heoi, nā runga i ngā ture ā-rohe me ngā herenga o te wāhi tāutanga, i whakamōhio mai te kiritaki me whai otinga pūnaha photovoltaic parakore anō hoki rātou hei huarahi kē.

I te wāhanga e whai ake nei, ka taea e tātou te whakahaere i ngā tātaitanga mō tētahi pūnaha papa rā parakore.
