Pulatifomu yapadera yoyenda ya granite yamakina owotcherera chingwe cha photovoltaic: 0.5μm/chaka chokhazikika chokhazikika. Kodi mungachepetse bwanji mtengo pa ola la kilowatt? ku

ku
Pampikisano woopsa wa "grid parity" mumakampani a photovoltaic, kukhathamiritsa kwa mtengo wa ola lililonse la kilowatt-ola lamagetsi kumakhudzana ndi mpikisano waukulu wamakampani. Monga chida chofunikira popanga ma module a solar cell, kulondola kwa nsanja yosunthika ya makina opangira chingwe cha photovoltaic kumakhudza mwachindunji momwe kuwotcherera ndi magwiridwe antchito. Pulatifomu ya granite yoperekedwa ku makina owotcherera zingwe za photovoltaic, yokhala ndi kukhazikika kwake kopitilira 0.5μm/chaka, imapereka chithandizo chaukadaulo chochepetsera mtengo pa ola la kilowati kuchokera ku miyeso ingapo. ku
Kukhazikika kwakukulu kumatsimikizira kuwotcherera kulondola komanso kumachepetsa zinyalala zakuthupi
Pa chingwe kuwotcherera ndondomeko ya maselo photovoltaic, kupatuka mu malo kuwotcherera kungayambitse osauka interconnection wa maselo, potero zimakhudza mphamvu m'badwo Mwachangu wa zigawo ndi ngakhale kupanga zosalongosoka mankhwala. Pulatifomu yoyenda yachikhalidwe imakonda kupindika chifukwa cha zinthu monga kusintha kwa kutentha kwa chilengedwe komanso kugwedezeka kwamakina, zomwe zimapangitsa kuti pakhale kusinthika kwa malo owotcherera. Coefficient of thermal extension of the granite sports platform is only (4-8) × 10⁻⁶/℃. Kuphatikizidwa ndi kapangidwe kake kakang'ono komanso kofananako, kukhazikika kwapakati kwa 0.5μm/chaka kumatha kukwaniritsidwa. ku
Kutenga 1GW photovoltaic module kupanga mzere monga chitsanzo, ngati wamba zoyenda nsanja anatengera, kupatuka kwa malo kuwotcherera chifukwa mapindikidwe dimensional kuposa 0.1mm, zomwe zingachititse kuwotcherera chilema cha maselo dzuwa kukwera kwa 3%. Mukamagwiritsa ntchito nsanja zamasewera a granite, chiwopsezo cha kuwotcherera chikhoza kuwongoleredwa mkati mwa 0.5%. Pakuchepetsa kulikonse kwa 1% pamlingo wopunduka, maselo a batri opitilira yuan miliyoni akhoza kupulumutsidwa chaka chilichonse, kutsitsa mwachindunji mtengo wopangira zida ndikuyala maziko otsika mtengo pa ola la kilowatt. ku

Chepetsani kuchuluka kwa kukonza zida ndikuwongolera magwiridwe antchito
Pulatifomu yosasunthika yosasunthika imapangitsa kuti zida zopatsirana ziziyenda mwachangu komanso kuchepa kwa malo chifukwa chakupindika pakagwiritsidwe ntchito kwanthawi yayitali, motero pamafunika kuwongolera ndi kukonza zida pafupipafupi. Mapulatifomu a masewera a granite, ndi kukhazikika kwawo kwakukulu, amatha kuchepetsa zochitika za mavuto oterowo. ku
Chifukwa cha mawonekedwe ake ang'onoang'ono a 0.5μm pachaka, kuchuluka kwa mavalidwe azinthu zazikulu monga njira yopatsira ndi sensa yamakina a makina owotcherera zingwe kumachepetsedwa kwambiri. Malinga ndi muyeso weniweni wa bizinesi ina yopanga photovoltaic, mutatengera nsanja yoyenda ya granite, kuwongolera makina opangira chingwe kumakulitsidwa kuchokera kamodzi pamwezi mpaka kamodzi kotala, ndipo nthawi yokonza imodzi yafupikitsidwanso kuchokera maola 8 mpaka maola atatu. Kuchepetsa kachulukidwe ka kukonza zida kumatanthawuza kuti kupanga bwino kwambiri komanso kutsika kwa zida zogwiritsira ntchito ndi kukonza ndalama. Kutengera mzere wopanga wokhala ndi mphamvu yapachaka ya 500MW, imatha kukulitsa nthawi yopangira bwino pafupifupi maola 200 chaka chilichonse, kupanga ma module a photovoltaic opitilira yuan miliyoni 5, ndikuchepetsa kwambiri mtengo pa ola la kilowatt. ku
Wonjezerani moyo wautumiki wa zida ndikuchepetsa ndalama zogulira
Ndalama zogulira zida zopangira photovoltaic ndizokwera, ndipo moyo wautumiki wa zidazo umakhudza mwachindunji kubweza ndalama zamabizinesi. Chifukwa chakusintha kwanthawi yayitali komanso kupunduka kwamapangidwe, nsanja zoyenda wamba nthawi zambiri zimalephera kukwaniritsa zofunikira zopanga mwatsatanetsatane kwazaka zopitilira zisanu. Zotsatira zake, mabizinesi amayenera kusintha zidazo pasadakhale, ndikuwonjezera kukakamiza kwa ndalama zokhazikika. ku
Mapulatifomu a masewera a granite, okhala ndi mphamvu zokhazikika zakuthupi ndi zamankhwala, amatha kukhala olondola kwambiri pakagwiritsidwe ntchito kwanthawi yayitali ndikukulitsa moyo wonse wautumiki wa makina owotcherera zingwe. Deta yochokera kwa wopanga zida zina za photovoltaic zikuwonetsa kuti makina owotcherera a chingwe okhala ndi nsanja ya granite amatha kukhalabe ndi malo olondola olowera mkati mwa ± 0.1mm atatha kugwiritsa ntchito mosalekeza kwa zaka 8, kukwaniritsa zofunikira zopanga zida zapamwamba kwambiri. Mosiyana ndi izi, zida zomwe zimagwiritsa ntchito nsanja zoyenda wamba ziyenera kusinthidwa kapena makina onse asinthidwa pakatha zaka zisanu. Kuwonjezedwa kwa moyo wautumiki wa zida kumathandizira kuti mtengo wokhazikika wabizinesi ugawidwe kwa nthawi yayitali, ndikuchepetsanso kutsika kwa zida pamtengo pa ola la kilowatt. ku
Kuthandizira kupanga zigawo zogwira mtima ndikuwonjezera ndalama zopangira magetsi
Kukhazikika kwapakati pa 0.5μm/chaka kumapereka chitsimikizo kwa makina owotcherera a chingwe cha photovoltaic kuti akwaniritse kuwotcherera kolondola kwambiri, zomwe zimathandiza mabizinesi kupanga ma module a photovoltaic ndikuchita bwino kwambiri. M'malo ogwiritsira ntchito magetsi, zida zogwira ntchito kwambiri zimatha kukwaniritsa mphamvu zopangira mphamvu zambiri komanso kuchepetsa kuchepa kwa mphamvu, motero kumapangitsa kuti ndalama zonse zopangira magetsi zitheke. ku
Mwachitsanzo, ma module okhala ndi magalasi awiri okhala ndi kuwotcherera kolondola kwambiri amatha kuwonjezera mphamvu zamagetsi ndi 3% mpaka 5% poyerekeza ndi ma module wamba. Tengani 100MW photovoltaic power station monga chitsanzo. Pogwiritsa ntchito zigawo zamphamvu kwambiri, zimatha kupanga magetsi owonjezera a 3 mpaka 5 miliyoni kilowatt-maola pachaka. Kuwonjezeka kwa ndalama zopangira magetsi kumatanthauza kuchepetsa mtengo wa kilowatt-ola, kupititsa patsogolo chuma ndi mpikisano wamagetsi a photovoltaic. ku
Pulatifomu ya granite yoperekedwa ku makina owotcherera zingwe za photovoltaic, yokhala ndi kukhazikika kwa 0.5μm/chaka monga phindu lake lalikulu, imachepetsa mtengo wopangira ma module a photovoltaic ndi mtengo pa ola la kilowatt wa malo opangira magetsi kudzera m'njira zingapo monga kuwonetsetsa kuti kuwotcherera molondola, kuchepetsa kukonzanso, kukonza zida, kukulitsa zida zamoyo, kukulitsa zida zamoyo. Amapereka chithandizo cholimba chaukadaulo kwa mafakitale a photovoltaic kuti akwaniritse "grid parity" ndi chitukuko chokhazikika.
