- Amamojula anezilinganiso eziphezulu zamandla athuthukiswa kumaphrojekthi esikali sosizo agcina izindleko ze-EPC ne-BOS ziphansi
- Izinzuzo zamamojula wamandla aphezulu zibonakala nakakhulu uma usebenzisa ama-inverters ezintambo nama-trackers
- Ubuchwepheshe be-Bifacial buya ngokuya buthandwa ezinhlelweni ezisetshenziswayo futhi ukuletha ama-tracker ekuxubeni sekuzoba yinzuzo enkulu
- Kulesi sigaba esisetshenziswayo sombiko sibale imikhiqizo ecishe ibe ngu-40 evela kubahlinzeki abangu-11 ehlanganisa bonke ubuchwepheshe bamamojula athuthukile.
I-Utility iyigatsha elikhulu kunawo wonke lezinhlelo zokusebenza ze-PV ezinokufakwa kwezinga elikhulu ezifinyelela esikalini se-GW. Lesi sigaba sethu I-TaiyangNews Solar Module Umbiko we-Innovations 2022 uxoxa ngamamojula athuthukisiwe ukuze afakwe phansi. Kumaphrojekthi esikali sosizo, intengo yemojuli ephansi iyisidingo esikhulu. I-metric ye-$/W ibilokhu iwumbandela oyinhloko wokukhetha amamojula esikhathini esidlule. Nokho, ingxenye ihamba kancane kodwa ngokuqinisekile yamukela i-metric ye-LCOE esekelwe ku-$/kWh. Ngakho-ke ngenkathi intengo izohlala igxilile, amandla emojula aphezulu yiwo abalulekile ngokujwayelekile ngokobuchwepheshe. Kunenkolelo ebanzi embonini yokuthi amandla emojula ephezulu asiza ukugcina i-EPC ne-BOS ibiza kancane. Kodwa amandla aphezulu ewodwa awanele. Izinzuzo zokuncishiswa kwezindleko ze-BOS zingabonakala lapho i-voltage yemodyuli igcinwa njalo ngenkathi ikhulisa i-module yamanje ukuze isibalo sezintambo sigcinwe. Ngokulandelayo, lokhu kusiza ukunciphisa izindleko ezihlobene nezingxenye zikagesi. Izinzuzo zamamojula wamandla aphezulu zibonakala nakakhulu uma usebenzisa ama-inverters ezintambo nama-trackers. Usayizi ungesinye isici esibalulekile semojuli lapho usebenzisa ama-tracker. Ukusetshenziswa okuphezulu kwendawo yokusekela i-tracker, enqunywa usayizi wemojuli, kuyisici esibalulekile okufanele sinakwe. Ubuchwepheshe be-Bifacial, obunamandla okwandisa isivuno samandla, ubuchwepheshe obuthandwa kakhulu, futhi ukuletha ama-trackers ekuxubeni kubonakala kunenzuzo nakakhulu.
Uhlu lwethu lwamamojula wesilinganiso sokusetshenziswa kwe-solar luqukethe imikhiqizo engama-40 evela kubahlinzeki abangu-11, ehlangabezana nombandela wokufaneleka oshiwo ngenhla. Kungaqashelwa ohlwini ukuthi umqondo wokusebenzisa amawafa amakhulu ukwandisa amandla aphezulu yilowo owamukelwe kahle. Kokubili i-G12 ne-M10, amafomethi amakhulu amabili atholakalayo kwezentengiso, amelela ingxenye enkulu - 11 kanye ne-17, ngokulandelana, ngesamba semikhiqizo engu-28 kwengu-40. Lolu shintsho lubaluleke kakhulu uma kuqhathaniswa nombiko wethu wangaphambilini, osanda kufakwa ohlwini lwemikhiqizo emi-4. Noma kunjalo, lokhu akukona ukumelwa okuphelele kwemikhiqizo yemojula yezinhlelo ze-PV zesikali esisetshenziswayo njengoba izinkampani zikhetha ukunweba i-spectrum yohlelo lokusebenza ngokuzibiza ngokuthi 'usizo ne-C&I'. Kuyacaca futhi ukuthi amamojula asekelwe kumasayizi amawafa amancane ayaphela buthule, anemikhiqizo engu-7 kuphela esekelwe ku-M6 futhi emi-4 kuphela esekelwe kufomethi ye-G1.
Mayelana nobuchwepheshe, uhhafu weseli kanye ne-MBB yimibandela yokufaneleka okungenani; kodwa i-bifacial iwubuchwepheshe obubodwa obuthandwa kakhulu ezinhlelweni zokusebenza. Njengoba kungase kubonakale ohlwini, imikhiqizo engu-15 kwengu-40 inobuso obubili, okusho ukuthi amamojula anikezwa ngokukhethekile njenge-bifacial noma umkhiqizo ofanayo utholakala kukho kokubili okuhlukile kobuso obubodwa kanye nobuso obubili ngesilinganiso samandla esifanayo. Izinhlobonhlobo ze-Bifacial zemikhiqizo eminingi nazo ziyatholakala kodwa ngokuvamile zinamandla aphansi angu-5 W. Leyo mikhiqizo, nokho, ayingeni ohlwini lwethu njengoba kuvela imojuli enamandla kakhulu yochungechunge.
Ngokuqondene nenani lamaseli, lincike ngokuphelele kusayizi we-wafer. Ku-G12, 132 kanye no-120 amaseli uhhafu amaseli amabili amakhulu. Ifomethi ye-M10 iza ngokucushwa okuningana okufana namaseli angu-156, 144, 132 kanye no-108.
Izibalo zamaseli ezingu-144 no-120 zivamile ku-M6, kuyilapho i-LONGi kuwukuphela kwenkampani enikeza imojula ye-PERC kusakhiwo samaseli angu-132. Imikhiqizo esekelwe ku-G1 evela ezinkampanini ezimbili kuphela - i-Talesun ne-Hyundai - ifanelekela lolu hlu lwezinsiza. Imojula ehlanganisiwe evela ku-TW Solar ibonakala ikhethekile lapha ngenani lamaseli angu-408, kanti ngalinye lamaseli angu-68 we-G12 lisikwa libe yizicucu ezingu-6. Eqinisweni, iyimojula elingana namaseli angu-132 esekelwe kusayizi weseli ye-G12.
Nakuba amamojula asekelwe ekwakhiweni kwamaseli okusebenza kahle kakhulu okufana ne-TOPCon ayengahloselwe kakhulu izinhlelo zokusebenza ezisetshenziswayo, ukuthambekela kubonakala kushintsha. Sinamamojula angu-8 e-TOPCon avela e-Jolywood, e-Suntech nase-Megasol. Futhi iJolywood ayiholeli kuphela ngaphakathi kwengxenye ye-TOPCon, kodwa lonke uhlu 'lwezinto ezisetshenziswayo kuphela'. Imojula enamandla kakhulu kulo mbiko, iphaneli ye-700 W 132-cell TOPCon esekelwe kufomethi ye-wafer engu-210 mm evela ku-Jolywood, ithuthukisiwe I-power plant thayipha ukufakwa. Bese, imojula ye-TOPCon ye-Suntech esekelwe ku-M10 enamaseli angu-156 uhhafu kanye namandla alinganiselwe angu-620 W nawo alebulwe izinhlelo zokusebenza ezisetshenziswayo.
Phakathi kwemikhiqizo ye-PERC, i-GCL ihlinzeka ngomkhiqizo onamandla kakhulu nosebenza kahle kakhulu; imojuli ye-G12 ekucushweni kwe-half cell engu-132 enamandla alinganiselwe angu-675 W kanye nokusebenza kahle okungu-21.7%. Ukulandela ukucushwa okufanayo, amamojula anamandla alandelayo ku-670 W avela ezinkampanini ezine - i-CSI, i-Suntech, i-Talesun ne-Trina. Ngaphandle kuka-Trina, zonke izinkampani ezingenhla nazo zinikeza amamojula we-G12 asekelwe ku-120-cell. Ngaphakathi kwefomethi ye-M10, yimojula ye-Suntech engu-590 W ephezulu ohlwini lwamandla. Njengoba sigcizelele embikweni wethu odlule, i-multicrystalline isendleleni yokuphuma. Nakuba uhlelo lwangaphambilini lwaluhlanganisa imikhiqizo emibili ye-multicrystalline, ayikho ngokuphelele esigabeni sokusetshenziswa kuphela salo nyaka.
