ME PĒHEA TE PŪNGAO RĀ O TE TAUPOKI? HE AHA NGĀ PAINGA O TE PŪNGAO HAU?

Ahakoa te mahana o te ao me te parahanga o te hau, kua kaha te tautoko a te kāwanatanga i te whanaketanga o te umanga whakaputa hiko o te rā i runga i te tuanui. He maha ngā kamupene, ngā umanga me ngā tāngata takitahi kua tīmata ki te tāuta i ngā taputapu whakaputa hiko o te rā ki runga i te tuanui.

Kāore he here ā-whenua mō ngā rauemi pūngao o te rā, he whānui te horapa, ā, kāore e pau. Nō reira, ki te whakaritea ki ētahi atu hangarau whakaputa hiko hou (whakaputa hiko hau me te whakaputa hiko koiora, me ētahi atu), ko te whakaputa hiko photovoltaic o te tuanui he hangarau whakaputa hiko pūngao whakahou me ngā āhuatanga tino pai mō te whanaketanga pumau. Ko ōna painga matua e whai ake nei:

1. Kāore e pau, kāore e memeha ngā rauemi pūngao o te rā. Ko te pūngao o te rā e whiti ana ki te whenua e 6,000 ngā wā nui atu i te pūngao e pau ana i te tangata i tēnei wā. Hei tāpiri, he whānui te horapa o te pūngao o te rā ki te whenua, ā, ka taea anake te whakamahi i ngā pūnaha whakaputa hiko photovoltaic ki ngā wāhi e mārama ana, ā, kāore e herea e ngā āhuatanga pēnei i te rohe me te teitei.

2. Kei ngā wāhi katoa ngā rauemi pūngao rā, ā, ka taea te tuku hiko ki ngā wāhi tata. Kāore e hiahiatia he kawe tawhiti, ka ārai i te ngaronga o te pūngao hiko i hangaia e ngā raina tuku tawhiti, ā, ka penapena hoki i ngā utu tuku hiko. Ka whakaratohia hoki e tēnei he whakaritenga mō te whakamahere whānui me te tono o ngā pūnaha whakaputa hiko rā ā-whare i te rohe hauauru he uaua te tuku hiko.

3. He māmā noa te tukanga whakawhiti pūngao o te whakaputa hiko o te rā i runga i te tuanui. He whakawhiti tika mai i ngā photon ki ngā irahiko. Kāore he tukanga matua (pēnei i te whakawhiti pūngao wera ki te pūngao miihini, te whakawhiti pūngao miihini ki te pūngao hikohiko, me ētahi atu) me te mahi miihini, ā, kāore he kakahu miihini. E ai ki te tātaritanga thermodynamic, he nui te whai huatanga o te whakaputa hiko photovoltaic, tae atu ki te 80% neke atu, ā, he nui te pūmanawa mō te whanaketanga hangarau.

4. Kāore te whakaputa hiko o te rā i runga i te tuanui e whakamahi wahie, kāore e tuku i ngā matū tae atu ki ngā hau kati kōtuhi me ētahi atu hau para, kāore e whakapoke i te hau, kāore e whakaputa haruru, he pai ki te taiao, ā, e kore e pāngia e ngā raruraru hiko, e te mākete wahie tonu rānei. Ko te ohorere he momo pūngao hou e tino matomato ana, e pai ana hoki ki te taiao.

5. Kāore he hiahia mō te wai whakamatao i te tukanga whakaputa hiko o te rā i runga i te tuanui, ā, ka taea te tāuta ki te koraha ururua me te kore wai. Ka taea hoki te hono ngāwari i te whakaputa hiko photovoltaic ki ngā whare hei hanga i tētahi pūnaha whakaputa hiko whare photovoltaic whakauru, e kore e hiahiatia he whenua motuhake hei noho, ā, ka taea te penapena rauemi utu nui o te papaanga.

6. Kāore he wāhanga tuku miihini o te whakaputa hiko o te rā i runga i te tuanui, he māmā noa te whakahaere me te tiaki, ā, he pumau, he pono hoki te whakahaere. Ka taea e te pūnaha whakaputa hiko photovoltaic te whakaputa hiko mā te whakamahi i ngā wāhanga pūtau rā anake, ā, nā te whānui o te whakamahi i te hangarau whakahaere hohe, ka taea te noho kore tiaki, ā, he iti te utu tiaki.

7. He pumau, he pono hoki te mahi a te whakaputa hiko o te rā i runga i te tuanui, ā, neke atu i te 30 tau te roa o te ora mahi. Ka taea e te roa o te ora mahi a ngā pūtau hiko silicon tioata te eke ki te 20 ki te 35 tau. I roto i te pūnaha whakaputa hiko photovoltaic, mena he tika te hoahoa me te āhua, ka roa hoki te ora o te pākahiko. Tae atu ki te 10 ki te 15 tau.
