Akoranga Take: Pūnaha Paewhiri Rā 80kW i te UK

Papamuri Take

E ai ki te kōrero i mua ake nei, kei a mātou tētahi kiritaki i te UK e nui ana te hiko e pau ana i tana wheketere tāonga. I tēnei wā, kua whai pūnaha papa rā 40kw e hono ana ki te whatunga hiko te kiritaki, engari kāore anō kia tutuki i te 300kwh hiko e pau ana i ia rā. Nō reira, me whakarato mātou i te otinga pai rawa atu ki a ia. I runga i te āhuatanga o te kiritaki i tēnei wā, i hangaia e mātou he otinga pūnaha ranu hau 140kw. Heoi, nā ngā ture ā-rohe me ngā herenga o te taiao tāutanga i te papa (400 mita pūrua), me whai otinga pūnaha papa rā parakore te kiritaki hei huarahi kē atu.

Tuhituhi

I runga anō i te whakaahuatanga o mua, i te mea ko te hohonutanga o te tukunga o te pākahiko pēhanga-tiketike 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.

Inaianei kei te kiritaki te 400 mita pūrua o te wāhi e wātea ana mō te tāuta i ngā panera rā. I te nuinga o te wā, ka taea te tāuta i te 40 kW o ngā panera rā ki runga i te 400 mita pūrua. Nō reira, ko te tapeke o te urunga o te rā he 80 kW. I roto i ngā āhuatanga pai o te rā, ko te whakaputa hiko o ia rā he tata ki te 320 kW, ko te tikanga he rawaka tonu mō te kawenga o ia rā. Kei te whiriwhiri tonu mātou i te kaitahuri Solis S6-EH3P (75-125)K10-NV-YD-H mō tēnei kaupapa. He tino māmā tēnei kaupapa. Ka taea e mātou te tatau i te wā whakahokinga moni mā te whakataurite i te whakaputa hiko me te whakamahinga hiko.

Tātaitanga Wā Whakahoki Pūtea

Tuatahi, ka tatauhia e mātou te whakamahinga hiko a te kiritaki. E 250 pea ngā rā mahi i roto i te tau, ā, ko te whakamahinga hiko o ia rā mahi he 300 kWh. Nō reira, ko te hiahia hiko ā-tau he 75,000 kWh. Ahakoa e whakaputa ana te pūnaha panera rā 80 kW i te UK i te nuinga o te wā i te 35,000 kWh o te hiko, me hoko mai te toenga hiko 40,000 kWh mai i te whatunga hiko i te pō.

E ai ki ngā rangahau ipurangi, ko te utu hiko mō te wā tino pīki ko te 23.22p/kWh, ā, ko te utu mō te wā kore pīki ko te 11.74p/kWh. Ko te rerekētanga i waenga i ngā utu arumoni mō te wā pīki me te wā kore pīki ko te 11.48p/kWh.

I runga i tēnei, ka taea te tatau i ngā penapena ā-tau penei:

35,000kWh (whakaputa hiko o te rā) × 23.22p/kWh = 812,700p

40,000kWh (hokonga whatunga i te tere kore-pīki) × 11.74p/kWh = 469,600p

Te tapeke o te utu hiko ā-tau me te kore he pūngao rā: 75,000kWh × 23.22p/kWh = 1,741,500p

Te tapeke o te utu ā-tau me te hoko pūngao rā me te hoko i waho o te wā pīki: 469,600p

Ngā penapena ā-tau = 1,741,500p – 469600p = 1271900P (16800$)

Mā te utu tāutanga, ka taea e tātou te tatau i te wā hokinga mai o te haumitanga o tēnei kaupapa pūnaha panera rā. Ko te wā hokinga mai o tēnei kaupapa me 6-8 tau.
