I te pikinga ake o te urunga mai o te whakaputanga pūngao hou, kua noho te whanaketanga o te rokiroki pūngao roa hei ia o te ao, ā, ko ngā huarahi hangarau mō te rokiroki pūngao roa tauine nui ko te rokiroki papu, te rokiroki tote wera rewa, te rokiroki au wai, te rokiroki hau kōpeke, me te rokiroki hauwai i roto i ngā wāhanga e rima. I tēnei wā, ko te whakamahinga rokiroki papu te mea tino pakari, engari ko ngā painga o te rokiroki pūngao hau kōpeke he tauine nui, he pai te mahi, he iti te utu, he tiaki taiao me te ma, ā, ka taea te whakakore i ngā here whenua, e tumanakohia ana ka waiho hei tāpiritanga ki te rokiroki papu.
Ko te rokiroki pūngao hau kōpeke he rokiroki pūngao roa, ka taea te whakamahi mō te wā roa neke atu i te 4 hāora, ngā rā rānei, ngā marama o te huringa utu me te tukunga o te pūnaha rokiroki pūngao, ā, he painga nui tēnei mō te whakahaere i ngā piki me ngā heke o te whakaputanga pūngao hou.
E ai ki te kaiwhakahaere o te pokapū rangahau me te whanaketanga rokiroki pūngao o te Whare Wānanga Pūtaiao Hainamana, a XuYuJie, i roto i te whakataki, ko te pūnaha hiko o tō tātou whenua he momo pūngao hou hei pūnaha hiko matua i te heke mai, ā, ko te mana hau, te whakaputa hiko photovoltaic me ētahi atu whakaputa hiko pūngao whakahou ka rerekē haere, ka mutu, ka tūpono te urunga nui ki te whatunga hiko. I tēnei wā, ko te hiahia mō te pūnaha rokiroki pūngao hei rauemi whakahaere ngāwari hei whakahaere i te pūnaha hiko. Ko te rokiroki pūngao hau kōpeke he mea nui.
"Ehara i te mea hou te hangarau rokiroki pūngao hau kōpeke, kua roa te hangarau rokiroki pūngao hau kōpeke tuku iho e whakamahia ana i Tiamana, i te Hononga o Amerika, engari ko te hangarau rokiroki pūngao hau kōpeke tuku iho e whakawhirinaki ana ki ngā wahie pūmua, te hiahia mō ngā ana taiao nui, te iti o te pai o te rokiroki pūngao me ētahi atu take, he iti tonu te whakatairanga nui." I kī a Xu Yujie ko te pūnaha rokiroki pūngao hau kōpeke matatau o Haina ka hangarua i te wera kōpeke, kāore e whakamahi i ngā wahie pūmua, ā, ka taea te whakamahi i roto i ngā momo āhua pēnei i ngā taputapu rokiroki i runga ake i te whenua, ngā rūma horihori me ngā ana taiao i raro i te whenua hei hanga rūma rokiroki. Hei tāpiri, ka tino whakapai ake te pūnaha i te pai o te rokiroki pūngao.
I tēnei wā, mā te whakamahi i te hangarau rokiroki pūngao hau kōpeke matatau 100 MW, kua hangaia e Haina te teihana hiko whakaaturanga rokiroki pūngao hau kōpeke matatau 100 MW o te ao tuatahi, ā, kua honoa angitu ki te whatunga hiko hei whakaputa hiko. Kei Zhangbei County, Hebei Province te teihana hiko, ā, koia te kaupapa i hangaia ai, i whakahaerehia ai hoki e te ao, ko te mahi nui rawa atu me te pai rawa atu o te tipu hiko rokiroki pūngao hau kōpeke hou. Ka taea e ia te whakaputa hiko tae atu ki te 132 miriona kWh ia tau, e whakarato ana i te tiakitanga hiko teitei mō te 50,000 kaiwhakamahi. I taua wā anō, ka taea e ia te penapena i te 42,000 tāne o te waro paerewa me te whakaiti i te 109,000 tāne o ngā tukunga hauhā ia tau.
He aha ngā painga o te rokiroki pūngao hau kōpeke i runga i ētahi atu momo rokiroki pūngao hou? I te nuinga, ka taea te whakarāpopoto he haumaru, he roa te ora, ā, he kaha te pahū. Tuatahi, he tino haumaru te rokiroki pūngao hau kōpeke. Hei tauira, ko te kaupapa rokiroki pūngao waro hauhā wai hei tauira, nā te mea he tino ngāwari te waimeha o te waro hauhā, nō reira he torutoru noa ngā megapascal o te pēhanga e hiahiatia ana mō te rokiroki, kāore e manukanuka ki te rokiroki hau pēhanga teitei i puta mai i te tūponotanga huna, i te wa ano kāore te waro hauhā i te paitini, kāore e mura, ā, he pahū, he tino pai te haumaru o ia anō. Hei tāpiri, nā te mea he taputapu miihini katoa, ka taea e te roanga o te ora o ngā pūnaha rokiroki pūngao hau kōpeke te eke ki te 30-50 tau i raro i te tiaki noa. "Ko te rokiroki pūngao hau kōpeke he tukanga ā-tinana e ahu mai ana i te huringa wera, he painga ā-taiao mō te haumaru me te whakahekenga mahi, ā, e kiia ana ko tētahi o ngā hangarau rokiroki pūngao nui rawa atu e tino whai hua ana." I runga i ēnei painga, kua kī a Chen Haisheng, he kairangahau i te Institute of Engineering Thermophysics o te Chinese Academy of Sciences, he mea nui rawa te whakamahinga o te hangarau rokiroki pūngao hau kōpeke, ā, he nui te tono a te mākete mō te whakatutuki i ngā whāinga rautaki waro-rua o te whenua me te whakapai ake i te taiao tūturu.
He mea tika kia whakahuatia ko te pahūtanga pūngao o te hau kōpeke he kaha te rokiroki pūngao. Ka taea e tēnei te mahi tika i roto i ētahi tono motuhake. Hei tauira, mō ngā miihini tīhiera e whakamahia ana i roto i ngā kaipuke nui, ko te hau kōpeke ka rongoatia i roto i te tāke pēhanga, ā, ka mahi tika ki te piston mā roto i te takirere tīmatanga motuhake hei huri i te porowhita i mua i te tīmatanga o te werohanga wahie. He iti ake te iti o tēnei whakaritenga, he iti ake te utu i te motuka tīmatanga hiko o te rahi kotahi, ā, ka taea te whakarato i ngā pahūtanga mana tino teitei e tika ana me te kore e utaina he kawenga nui ki runga i te pūnaha whakaputa me te tohatoha o te kaipuke.
Mō ngā pūnaha rokiroki pūngao hau kōpeke, kei te whakapakari ake a Haina i ngā whakaaturanga me ngā tono nui, kei te kohikohi wheako ki te hoahoa me te hanga hangarau, me te whakawhanake i tētahi mekameka ahumahi kua oti me te pakari hei tere ake i te hanganga me te tono.
