He ngoikore te kaha ā-ringa o te pūtau hiko hiko tioata, ā, he ngāwari ki te pakaru. Ka āta waikura te hikohiko e te makuku me ngā hau waikura i te rangi, ā, ka kore e taea te tu atu i ngā āhuatanga mahi uaua i te rangi tuwhera. Nā tēnei take, ka tākaihia ngā pūtau hiko hiko e te karāhe photovoltaic mā te EVA me te papa o muri. Ko te karāhe photovoltaic i roto i ngā kōwae photovoltaic hei tiaki i te pākahiko mai i te wai me te hau e memeha ana, hei aukati i te hāora hei ārai i te waikura, te ātete ki te pāmahana teitei me te iti, te pai o te whakamarumaru me te ātete ki te koroheketanga. Ko te karāhe photovoltaic he momo karāhe silicate he iti te ihirangi rino, e mōhiotia ana ko te karāhe whakairo ultra-mā.
He rerekē te karāhe photovoltaic e whakamahia ana i roto i te pūtau silicon tioata i te karāhe pōrewarewa. He hiako te mata o runga o te karāhe photovoltaic, ā, he uaua ki te mārama te whiti tika ki te mata o te kōwae ki te whakaputa whakaata ā-whatu. He whakairo te mata o raro, ka taea te whakanui ake i te kaha piri ki te kiriata EVA.
Ngā wāhanga matua o te karāhe photovoltaic
Ko ngā rauemi mata matua o te karāhe photovoltaic ko te onepu quartz, te pungarehu houra, te kōhatu, te dolomite, te konutai nitrate, te tote glauber, te konutai pyroantimonate, te konumohe hauwai, me ētahi atu. Ko te onepu quartz te nuinga o te mahi a te tinana hanganga whatunga, ko te horopeta te nuinga o te wāhanga karāhe, ko te pungarehu houra te nuinga e whakamahia ana hei whakarato i te konutai waikura, ko te nuinga hei whakaiti i te pāmahana rewa o te karāhe; ko te mahi matua a te kōhatu ko te whakarite i te matotoru o te karāhe ki te uara tika, kia tutuki ai te wā whakahāngai karāhe i ngā whakaritenga o te whakahāngai, ko te tote glauber te nuinga e whakamahia ana hei whakamārama, hei whakakore i ngā mirumiru i roto i te karāhe, hei whakarato i te whakawhiti karāhe.
Te ōwehenga kai rauemi mata o te karaihe photovoltaic
Ko te tikanga o te whakarite i te karāhe photovoltaic he tikanga tātaitai, ā, ka taea te wehewehe i te tukanga whakaputa kia rua ngā wāhanga: te whakaputa pepa me te tukatuka hohonu. Ko te nuinga o te mahi whakaputa taketake ko te puranga, te rewa, te tātaitai, te whakamahana me te tapahi. Tata ki te 1100 ℃ i roto i te tukanga hurihuri, ka hurihia te karāhe rewa, ka hurihia, ka whakamataohia e ngā roera tātaitai, kia tae ki tētahi tere ki tētahi matotoru, ki tētahi whānui, ki tētahi tauira, mā roto i te karāhe o te tere o te 91.5%. I muri i te whakamahana, ka hangaia he pihi ahotea pumau mō te karāhe, kia whai kaha, kia kore e pakaru, kia pai ai te tapahi, te tukatuka karāhe. He mea tika kia tohuhia he rerekētanga i waenga i te raina whakaputa o te karāhe whakairo photovoltaic me te karāhe mānu.
Ko te tukanga tukatuka hohonu te tikanga he paninga karāhe taketake me te whakapakeke, ko te paninga he whakapai ake i te whakawhiti o te karāhe photovoltaic, ko te whakapakeke he whakanui ake i ngā āhuatanga miihini o te karāhe, ko te kaha piko o te karāhe whakapakeke he 3-5 ngā wā i te karāhe noa, ko te kaha pānga he 5-10 ngā wā i te karāhe noa, ka whakapai ake i te kaha engari ka whakapai ake hoki i te haumaru.
Te rere o te tukanga karāhe photovoltaic
Ko te mahi a te karāhe photovoltaic 02 me whai pai te whakawhiti mārama o te karāhe photovoltaic. I te nuinga o te wā, ko te whakawhiti mārama o te pepa maitai kāore i pania (te awhe roangaru mai i te 380nm ki te 1100nm) he nui ake i te 91%, ko te whakawhiti mārama o te karāhe pania i muri i te tukatuka hohonu ka eke ki te taumata o te 93.5%. Hei tāpiri, me tutuki i te karāhe photovoltaic ētahi ātete huarere me ngā āhuatanga miihini. E ai ki te GB T 30984.1-2015 "karāhe pūngao rā wāhanga 1 karāhe whakairo ultra-ma", ko te mahi iti rawa o te karāhe photovoltaic e whakamahia ana mō ngā kōwae photovoltaic me tutuki i ngā whakaritenga e whai ake nei.
Te umanga karaihe photovoltaic i Haina
He teitei ake ngā arai o te umanga karāhe photovoltaic, he teitei ake te kukū, me kohikohi roa te wheako me te tukanga whakaputa kotahi-mutu mō te whakaputanga, ā, me nui ake te haumitanga tuatahi. Ko te kaha o te oumu karāhe photovoltaic 900 tana/rā me haumitanga tuatahi RMB 9,550 tana o te haumitanga oumu e tata ana ki te 3-400 miriona yuan, ā, he iti ake te utu hanga o te oumu nui i te oumu noa (he iti te whakapaunga pūngao ki te 20%). Nō reira, he mārama te pānga o te umanga karāhe photovoltaic, ā, ko te nui o te hangarau matua rewa kei roto i ngā ringaringa o ngā umanga matua, ko ngā umanga iti me te rahi-waenga kāore i te kaha hangarau me te kaha ōhanga ki te haumi ki te hanganga o te 1000 tana o ngā oumu.
Mai i te wā i pakaru ai a Haina i te paepae hangarau o te hanga karāhe photovoltaic i te tau 2006, kua tere te whanaketanga o te umanga photovoltaic ā-rohe i roto i te iti iho i te 10 tau. Whai muri i te whakawhirinaki katoa ki ngā kawemai, kua riro a Haina hei kaihanga karāhe photovoltaic nui rawa atu o te ao. Neke atu i te 90% o ngā kōwae silicon tioata o te ao e whakamahi ana i te karāhe photovoltaic i hangaia i Haina. Ki te whakatauritea ki ngā umanga o tāwāhi, he mārama ngā painga o te karāhe photovoltaic a Haina i roto i te kounga me te utu. I te Hakihea 2017, e 24 ngā hua karāhe ultra-mā, 40 ngā oumu me te 135 ngā raina whakaputa i Haina, me te katoa o te kaha whakaputa o te 21,290 tana/rā. I tatauhia i runga i te taumata hua toharite o te ahumahi o te 78%, ko te whakaputa ā-rohe o ngā wahi mata karāhe ultra-mā he tata ki te 14,773.20 tana/rā.
Ngā tumanakohanga mākete
Ko te tau 2018 te tau tuatahi mō te whakarewatanga o ngā wāhanga taha-rua, ā, ka tere te pikinga o te wāhi mākete o ngā wāhanga taha-rua, ka akiaki i te hiahia mō te karāhe photovoltaic. E ai ki te tātaitanga, ko te hiahia mō te karāhe photovoltaic kei roto i te ripanga e whai ake nei. I te mea me whakatika matao ētahi oumu karāhe photovoltaic tawhito i te tau 2018, ka iti iho te kaha whakaputa tuturu o te karāhe photovoltaic i te kaha whakaputa ingoa, ā, kei te taurite te tuku me te hiahia mō te karāhe photovoltaic i te tau 2018.
E ai ki ngā hua, mai i te hauwhā tuawhā o te tau 2017, he iti te tono me te tuku o te karaihe photovoltaic. I te tīmatanga o te tau 2018, i raro i te kaupapa o te umanga photovoltaic i te hauwhā tuatahi he wā kore-wā, i te pikinga o te utu o te karaihe photovoltaic, ko te pepa paninga he 31 yuan ia mita tapawha neke atu rānei, ko te utu o te karaihe he 21 yuan ia mita tapawha neke atu rānei, ko te utu o te karāhe he 21 yuan ia mita tapawha neke atu rānei, ko te pikinga o ngā utu ka nui ake te taumata tawhē o te umanga karaihe photovoltaic.
