E hono ana ngā paerewa ra o te rā ki ngā mea nui mō ngā whare me te taiao. He iti noa iho ngā tangata e hiahia ana ki te hoko i ngā ara hei whakaiti i te nui o te ēneiti i whakamahi, me te whakaiti i te moni. Ka āhei ngā paerewa nei ki te hanga ēneiti horoiwai, ā, ka taea hoki te whakangungu i te mate huringa āhuarangi.
Hei whakarerekē, ka hurihia te mā whakaata ki te waiora. Ko tēnei e pā ana i te āhuatanga e mōhiotia nei hei ‘photovoltaic effect’. I te waehanga o te mā ki ngā paepae, ka whakaputu mai i te waiora kahurangi e taea ana te whakamahi hei orohanga i ngā mea kei roto i tō whare. Ko tēnei he mea nui no he mea koia e mahi ai ngā tangata ki te whakaputa i ō rātou waiora aoao, me te whakaiti i te whakamahi i ngā puna kore-tirohanga, pērā i ngā momo paeroa.
Ki te whakatūwhera koe i ngā rau marama, ka taea e koe te iti i ngā utu waihanga. Tiakina ngā moni mō ngā pūtea marama, nā tō koe whakahoahoa i ō rāpunga waihanga mai i te rā. Ko tēnei e whai take ana kia whai koe i te moni i roto i ngā tau e whai ake nei, ā, he pai hoki tēnei mō te ao nā te mea ka noho wehe i ngā kaiwaimarie.
Te mea hē ki te riro anō, ko ngā rau marama kaore i aua he maha ngā mahi tirotiro. Ki muri i te whakatūwhera, ka noho waiaroa ake te tirotiro. E taea ana e ngā rau marama, me te whāwhā ā-pori me ngā mahi tirotiro itiiti, ki te noho i waenganui i ngā tekau tau, tuku atu he waihanga tūpuhi, tūroro, me te waiariki hei whakamahere haere tonu mō tō whare.
Ā, ko te mea hē hoki, ka whai take ake ngā rau marama i te uara o tō whare. Kei te hiahia tēnā iwi e hokona ana i ngā whare kia whakapā kētia e rātou ngā moni mo ngā whare kua puta mai i mua me ngā rau marama. Nā tēnei, ko ngā rau marama he whiwhinga pai mō te tūroa. Ki te whakatūwhera koe, kaore pea koe i whakaae i a koe anake, engari heoi, ka whakaae anō koe i te whenua (me ngā uri whakatupu).
Ka pai ki te whakamahere i te wā e kī ai ngā pūtaiwhenua nei, ka hanga rātau he huringa ā-mahi e wehe ana i te paerewa ki tētahi kauhau. Ka whakawehi te kauhau i te huringa torotika (DC) i hangaia e ngā paerewa nei ki te huringa whakaputa (AC), e taea ana te whakamahi i roto i tō whare. Ka tukuna te huringa AC ki tō pāmuha ā-āhuatanga, kei reira ka taea te whakahaere i ō mīhini.
Ka mohio ai ngā tangata whenua i te mea e āhei ai te whakamahi i ngā paerewa ra o te rā hei whakamohio i ngā whakatau pūkenga mō te ēneiti. E āhei ana ngā paerewa ra o te rā ki te whakamahi i te ēneiti me te tiaki i te whenua i te wā e hanga ai ngā uara ēneiti hou, ka tuhituhia mai i tēnei taonga nui ki te rōpū 'Lets-Read-and-Find-Out'.
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.
