Piki ake ki enei whakahaerenga Creative Commons: Pūputu rā (Photovoltaic cell) Ko ngā pūputu rā, e mōhio ana he pūputu photovoltaic (PV), he mea pai nui rawa te hanga nei hei āwhina i a tātou ki te whakamahi i te waiora o te rā. Nō reira, nui ngā pūputu nei, inahea ka whakaiti i a tātou moni whakaeke ēnei, ā, ka tiaki hoki i tō tātou taiao. Enei āhuatanga e whakaatu ana i te mea e hiahiatia ana e ngā pūputu nei, ā, he nui ngā take e pa ana ki tēnā!
Ae, he aha nga pai o nga paerahi ra? He whakamahia nui rawa he mea kua taea hoki te whakaorangorango i te utu whakamahi mateika. I te wa e whakamahi ana tatou i nga paerahi ra ki te hanga rangi, kaore e tere nei te utu mo nga uara mahana penei i te para, ko te kauri. Ko tenei hei whakangungu moni moku, ahakoa kei te awhina hoki i te whenua.
Ko ngā pānui rā he nui ngā pūmau hauora, nā te mea he pai noa iho ki te whenua. Kaore i whakawhanake i ngā hau kino e āhei ana ki te whakaputu i te hāpori i te wā e whakamahi ana i ngā pānui rā. Ko tēnei kei te whakihiihi ki te whakapai i tō tātou whenua hei oranga mō ngā pepeke katoa e tae mai nei.
Te uru whakaata hei tūmomo pai mō te waihanga. E hīkohia ana e mātou i te wā e uta nei, kāore i te whakamutu i a rātou i te waihanga. Ko te waihanga mai i te rā he waihanga whakaoranga, ko tēnā kaore e whakamutunga. Ko tēnei te take i te mea he pai rawa ngā paepae uru whakaata hei hanga i ā mātou whare, kura me ngā pakihi.
Ko ngā paepae uru whakaata e kite ana i te uru o te rā, ka whakawhiti ki te hiko. I te waehanga o te uru whakaata i te uru rā, ka puta he hiko nui e taea ana te whakahaere i ngā māngaro me ngā whakahoahoa. Ko tēnei te mahi e mōhiotia ai hei whakawhiti hiko, ko tērā te take i te mea ka whakaputa i te hiko i ngā paepae uru whakaata.
He mea hou kei runga i ngā paepae uru whakaata, kāore i te mea iti te tirotiro. I te waenga o te whakatū, ka puta he hiko i ēnei tau katoa, kāore i te mōhio nui. Nō reira, he mōhio nui, he rangatira ngā paepae uru whakaata hei tūmomo waihanga mō ngā whare me ngā pakihi.
Te whitiwhiti ki te waiora rā he whakamahinga nui hei whai wāhi i te mana motuhake ēnei. Āe mea kia horoia te ēnei i ngā pūputu rā, kaore tātou e hīkoi ana ki runga i ngā whenua o era atu i te ao hei whakahokia mai i te papa (oil) rānei ko te coal. Kei tātou te mana ki te hanga i tōna ēnei pai nei i roto i ō tātou whare anō, he pai nui ai mō tā tātou ahurea, ā, ka taea e tātou te whakarite i tētahi wā kia ora.
Nau mai ki DHC, te tohu tuatahi mō ngā rangapū hau rā whakamahia! Tēnā tā matou mahi hei whakamārama i ngā whakaaetanga hou me ngā pūtake hou, ā, ina whai kē, he pūhanga hau, he pāne tāwhiti, he pouaka lifepo4, ānei.
