Pūnaha Pane Rā Kāinga: Te Hurihanga mai i te "Rārangi Hiko" ki te "Whakawātea i te Kaha"

I waenganui i te nuinga o ngā utu hiko kua piki haere i te ao, kei te māmātia e te whānau te rā he kāri hiko rā ki te kāinga hei "kōpaki hiko". Kāore anō pea i te huri i te hiko mai i te "utu takitahi" ki te "whakaputanga ake", engari hoki kei te whakapūmahara i te uara i runga i te 25 tau.

Pēhea te Māmātia i te Whare e te Whare Kaihiko Rā?

Ko te 5kW tūmatanui pūnaha huringa rākau mō te kāinga , i tētahi wāhi e whā haora te rā e tū nei he tino āhua, e 6,000-8,000 kWh te hiko e hāngai ai i te tau—e 70%-90% pea te hiko e herea ana i te tau ki te whānau.

Ko te mea anō hoki he pai ake te "utu hiko kua tohua": ina heke te nui ake o te hiko i te huihuinga o te whānau, ka taea te whakaputu i te hiko ki te tūāhonui, me te hoko anō e te kamupene hiko i te utu takitahi. Ko te tikanga, ko ētahi whānau e hāngai hiko mō te whakamahinga ake i te whānau, me te whiwhi hoki i te moni e hoko ana i te hiko kua tohua.

He nui ngā tautohe mō te utu tīmatanga teitei, engari he rerekē ngā kaupapa tāwhiwhi o ngā whenua ki te ao, e whakaiti nui ai i te kōtaha ki te whakauru i te paparorohiko awhārangi kāore he rerekē.

Ngā āhuatanga hei whai mōhio mō te hoahoa i te pūnaha hiko awhārangi

Ko te DHC tētahi kaihuinga o ngā whakautu kotahi-kiru māuiui ki te tau pōwhara maha i te ahumahi hiko whakarewa. Kei te hoahoa mātāturingia ngā whakautu mā ō mātou kiritaki, ka tirohia ngā āhuatanga katoa o pūnaha hiko solar .

1. Whai mōhio ki te wāhi e whakamahia ai te pūnaha hiko awhārangi me ngā tikanga awhārangi o te takiwā;

2. Whai mōhio ki te kaha o te pāpaku e mana ai te pūnaha;

3. Ko te totohu o waho o te pūnaha, me te āhua o te hiko DC, AC rānei e whakamahia ana;

4. Te maha o ngā haora e hāia ai te pūnaha i ia rā;

5. E hia ngā rā e hāia ai te pūnaha hiko awhārangi i te wā o ngā rā ua, ngā rā kapua kāore he rā;

6. Whai mōhio ki te momo pāpaku: he aha ko te pāpaku tīpure, te pāpaku whakakaha, te pāpaku whakarewa rānei, me te kaha o te wehenga tuatahi.

7. Whai mātāpuna ki te wāhi e hiahia ana te kiritaki ki te whakauru: whenua, te takotoranga o runga ki te whare rānei. Mēnā kei te takotoranga o runga ki te whare te whakauru, whai mātāpuna ki te kaha o te pātō.

Ko te Painga ki te Taiao: Te Whakaparea i te Whenua

Ko tētahi punaha 5kW e taea te whakaiti i ngā whakaputanga CO2 ki te 5 tōne i ia tau, e ōrite ana ki:

Whakaiti i te taraiwa waka ki te 12,000 kīromita;

Te tarukawa e 200 rakau;

Whakaparea i te 25,000 rītia wai māori (te whakamahinga wai mō te hāngai hiko hiko).

Mā te whiriwhiri i te punaha paparorohiko mārō whare e whakaiti i te utu mōu whānau, ā, ka tautoko hoki ki te whakamarumaru i te taiao. Mēnā he pāpaku ki a koe, whakapā atu ki a mātou ināianei kia whiwhi koe i tētahi whakatakotoranga kore utu.
