Ko ngā kōwae ngāwari, he hua hou i roto i te umanga photovoltaic solar (PV), kua kukume i te hiahia whānui o te mākete mō ō rātou āhuatanga mama, whai hua, me te ngāwari ki te tāuta. Heoi, i te whanaketanga o te hangarau, ka piki haere te rahi o ngā kōwae ngāwari, ka puta he tautohetohe whānui i roto i te umanga: ko te nui ake ko te pai ake? Ka whakaatuhia e tēnei tuhinga he rangahau hōhonu mō tēnei kaupapa, e whakaatu ana i ngā painga me ngā ngoikoretanga o ngā wāhanga ngāwari rahi nui, kia noho hei tohutoro whai hua mō te whanaketanga o te umanga.
Tuatahi, ko ngā painga o te rahi nui e whakanui ana i te whai huatanga o te whakaputa hiko.
Tuatahi, ko ngā wāhanga ngāwari rahi nui ka whakarato i ngā painga nui mō te pai o te whakaputa hiko. Mā te horahanga nui ake ka taea e te wāhanga te mimiti i te hihi o te rā, ka whakarei ake i te pai o te hurihanga hiko whakaahua. Hei tāpiri, ka whakawhāitihia e ngā wāhanga rahi nui te tawhiti i waenga i ngā wāhanga, ka whakaiti i te ngaronga mārama me te whakarei ake i te pai o te whakaputa hiko katoa.
Heoi, he mea nui kia mōhiotia kāore ngā kōwae rahi e whakarato i ngā hua pai rawa atu i ngā wā katoa. Hei tauira, kāore pea ngā kōwae rahi e kaha ki te whakamahi i ō rātou kaha whakaputa hiko whai hua i roto i ngā taiao iti te mārama. Hei tāpiri, kāore pea ngā kōwae rahi e kaha ki te urutau ki te taiao papa i ngā wā he iti te wāhi tāutanga.
Tuarua, te tātaritanga utu-painga; kāore pea e tika te rahi nui.
He nui ake ngā utu hanga me te kawe o ngā waeine ngāwari rahi nui ina whakaritea ki ō rātou painga. Nā te rahi nui ake, he nui ake ngā rauemi me ngā taputapu e hiahiatia ana mō ngā wāhanga i te wā o te tukanga hanga, engari he arai anō mō te kawe. Tērā pea ka nui ake ngā utu hanga mō ngā wāhanga rahi nui i ēnei āhuatanga, ka pā ki tō rātou whakataetae mākete.
Hei tāpiritanga, tera pea ka nui ake ngā utu tāutanga me te tiaki a ngā kaiwhakamahi mutunga mō ngā wāhanga nunui. Ko ngā huihuinga nunui e hiahia ana ki te nui ake o ngā tāngata me ngā taputapu i te wā tāutanga nā te taumaha me te rahinga. Mō te tiaki, tera pea ka uaua ake te whakahou me te whakakapi i ngā wāhanga nunui.
Tuatoru, me whai whakaaro ki te horopaki tono; me whakarite te rahi.
He whānuitia ngā whakamahinga o ngā kōwae ngāwari, tae atu ki ngā pūnaha PV tohatoha, ngā teihana hiko whenua nunui, me te whakaurunga whare, me ētahi atu. He rerekē ngā rahi o ngā wāhanga e hiahiatia ana mō ngā momo whakamahinga rerekē.
He pai ake pea ngā kōwae iti ake i roto i ngā pūnaha hiko pūngao rā kua marara noa atu nā te iti o te wāhi tāutanga. Ka taea e rātou te urutau ki ngā momo hanganga tuanui me ngā tikanga tāutanga, ka whakaiti i ngā utu tāutanga. Ka taea e ngā kōwae rahi i roto i ngā tipu hiko whenua nui te whakaiti i te tawhiti o ngā kōwae me te whakanui ake i te pai o te whakaputa hiko katoa.
Mō te whakaurunga o te whare, me rite te rahi me te āhua o ngā kōwae ngawari ki te hanganga tonu. Nō reira, i te wā e whiriwhiri ana i ngā rahi o ngā wāhanga, he mea nui kia whakaarohia te momo hoahoa me te hoahoa whānui o te pūnaha rā.
Tuawhā, i te whanaketanga o te hangarau, ka huri te ngāwari hei huarahi hou.
Ahakoa ngā painga o ngā wāhanga māmā me ngā wāhanga ngāwari nui i ētahi wā, nā te whanaketanga o te hangarau PV, kua noho te ngāwari hei huarahi hou mō te whanaketanga ahumahi. He ngāwari ake te urutau me te ngāwari o ngā wāhanga PV ngāwari, ā, he pai ake mō ngā tautuhinga uaua me ngā āhuatanga tāutanga.
Ka piki haere tonu ngā wāhi tono o te hangarau PV ngāwari i a ia e whakapai ake ana, e pakeke haere ana. I taua wā anō, ka whakawhānuihia te rahi o ngā kōwae PV ngāwari, ka whakawhaiarohia hoki kia rite ki ngā hiahia o ngā kaihoko rerekē.
Hei whakarāpopototanga, kāore te rahi o ngā kōwae ngāwari e whakapai ake i te pikinga o te rahi. I te whakatau i te rahi o te kōwae, me whai whakaaro ki ētahi āhuatanga, tae atu ki te whai huatanga o te whakaputa hiko, te whai huatanga o te utu, ngā āhuatanga tono, me ngā au whanaketanga hangarau. Mā te tātari tika me te aromatawai i ngā paearu maha ka taea e tātou te whiriwhiri i te rahi tino tika o ngā kōwae mārama me ngā kōwae ngāwari hei whai wāhi ki te tipu o te rāngai pūngao hou o te rā.
