Tātaitai Penapena Panara Rā

Ka rerekē ngā utu pūnaha papa hūhū rā i Aotearoa e ai ki te rahinga pūnaha, waitohu, uaua o te tūtūnga, me te wāhi. I te tau 2024–25, ko tētahi pūnaha noho 6 kW noa (tōtika mō tētahi kāinga NZ toharite) ka utu tata $12,000–18,000 ka tūtūhia katoa, tae atu ki ngā papa, hurumahi huri, tauranga, me ngā mahi. Ko ngā pūnaha iti ake 3 kW ka tīmata tata $7,000–9,000, ā ko ngā pūnaha nui ake 10 kW mō ngā kāinga kaihokohiko nui, mō ērā e tāpiri ana i tētahi pūkaha hiko rānei ka utu $20,000–35,000. Ka tāpiri te rokiroki pūkaha (hei tauira, tētahi Tesla Powerwall 10 kWh, ōrite rānei) $12,000–20,000. Ko ngā waitohu matua (SunPower, Panasonic) he utu nui ake engari he hāpai tino roa. Ka tūtohuhia ngā utu maha mai i ngā mema Solar Energy Association of New Zealand (SEANZ). Kāore he āwhina kāwanatanga ā-motu mō ngā papa hūhū rā i Aotearoa i te tau 2025.

Ko te wā whakahoki utu mō ngā papa hūhū rā i Aotearoa noa i waenga 7 ki te 12 tau, e ai ki te utu pūnaha, te kaihokohia hiko kāinga, te māramarama rā ā-rohe, me te rēti hokohoko i whiwhi mō ngā hiko i hua kawe. Ko tētahi pūnaha 6 kW utu $15,000 ka tūtūhia i tētahi kāinga Tāmaki Makaurau toharite e whanake ana i te 8,000 kWh/tau ka tiaki tata $2,800–3,200/tau i ngā pire hiko (i te 35 heneti/kWh kaihokohia ake), e homai ana i tētahi whakahoki utu tata 5–6 tau mō ngā āhuatanga pai rawa. Heoi anō, ko ngā kāinga ka noho kē i ngā hāora ao me te hua kawe i te nuinga o ngā whanakehanga ka iti ake ngā tiaki. Ka whakataro anō ngā wā whakahoki utu i ngā rere rā iti o raro o Te Waipounamu. Ka nui ake te utu tōmua ki te tāpiri rokiroki pūkaha engari ka pai ake te kaihokohia ake ki te 80–90%. Ko ngā wā ora pūnaha o 25+ tau ko te nuinga o ngā kainoho kāinga ka ea ngā tiaki nui roa.

Kāore i Aotearoa tētahi kaupeka net metering ā-motu ōkawa. Engari, ko ngā kāinga he papa hūhū rā ō rātou e hua kawe ana i ngā hiko toenga ki te whatunga, ka whiwhi i tētahi rēti 'hokohoko' (ka kīia anō ko tētahi tāke tuku hiko rā, credit hua kawe rānei) mai i tō rātou kaiwhakarato hiko. He rerekē ngā rēti hokohoko mā te kaiwhakarato, kāore anō i whakaritea ōkawatia. Ka rere ināianei mai i te tata 8 ki te 17 heneti ia kWh — he tino iti ake i te rēti hoko kaihoko o te 30–38 heneti/kWh. Nā tēnei tikanga, he uara nui ake rawa te kaihokohia ake o ngā hiko rā (whakamahi i ōu whanakehanga i a koe e whanake ana) i te hua kawe. Ka homai e ētahi kaiwhakarato (hei tauira, Meridian, Contact, Flick) ngā rēti hokohoko teitei ake, ngā rēti rerekē-wā rānei hei ākiaki i ngā hūhū rā. Heoi anō, kāore he tāke tuku hiko ā-motu i whakaaetia e ngā ture i Aotearoa. Mā ngā rokiroki pūkaha e āwhina ki te neke i ngā whanakehanga ki ngā wā taumaha ahiahi, e whakanuia ana i te kaihokohia ake. Puna: Electricity Authority (ea.govt.nz); SEANZ (seanz.org.nz).

I te tau 2025, kāore he āwhina kāwanatanga ā-motu, ākiaki tāke rānei ōkawa mō te tūtūnga papa hūhū rā noho i Aotearoa, ā he ruarua anō ngā mana kāwanatanga ā-rohe (kaunihera) e hoatu ana i ngā ākiakinga pūtea tōtika. Heoi anō, ko ētahi kaunihera kua whakauru i ngā hōtaka toitūtanga me ngā kōwhiringa pūtea rēti-iti. Hei tauira, ko ētahi kaunihera kua hoatu i ngā pūtea i pūteahia mā ngā rēti (ōrite ki ngā kaupeka Property Assessed Clean Energy i tāwāhi), e āheitia ana ngā kainoho kāinga ki te whakahoki i ngā utu tūtūnga papa hūhū rā mā ō rātou rēti i roto i te wā. Ā, ko ētahi kamupene raina me ngā kaiwhakarato hiko ka hoatu i ngā whakaheke utu, ākiakinga rānei. Ka pūtea te hōtaka Warmer Kiwi Homes a te kāwanatanga o Aotearoa i ngā perehitanga whare me ngā whakamahana (tae atu ki ngā pāmu mahana) mō ngā kāinga e tika ana engari kāore e āraihia ana ngā papa hūhū rā. Me rapu ngā kainoho kāinga ki tō rātou kaunihera ā-rohe me tō rātou kaiwhakarato hiko mō ngā ākiakinga ā-rohe o nāianei. Puna: SEANZ (seanz.org.nz); EECA Energywise (energywise.govt.nz).
