Kukhuphiswano oluqatha "lwegrid parity" kwishishini le-photovoltaic, ukulungiswa kweendleko ze-kilowatt-yure nganye yombane kunxulumene nokhuphiswano oluphambili lwamashishini. Njengesixhobo esibalulekileyo ekuvelisweni kweemodyuli zeseli zelanga, ukuchaneka kweqonga elihambayo lomatshini wokuwelda wentambo ye-photovoltaic kuchaphazela ngokuthe ngqo umgangatho wokuwelda kunye nokusebenza kakuhle kwemveliso. Iqonga le-granite motion elinikezelwe kwiimashini zokuwelda wentambo ye-photovoltaic, elinozinzo lwalo olupheleleyo lwe-0.5μm/ngonyaka, libonelela ngenkxaso yobugcisa yokunciphisa iindleko nge-kilowatt-yure nganye ukusuka kwiimilinganiselo ezahlukeneyo.
Uzinzo oluphezulu luqinisekisa ukuchaneka kokuwelda kwaye kunciphisa inkunkuma yezinto eziphathekayo
Ngexesha lenkqubo yokuwelda ngentambo yeeseli ze-photovoltaic, ukuphambuka kwindawo yokuwelda kunokukhokelela ekudibaneni kakubi kweeseli, ngaloo ndlela kuchaphazela ukusebenza kakuhle kokuveliswa kwamandla kweemodyuli kwaye kuvelise neemveliso ezineziphene. Iqonga lokuhamba lendabuko lithambekele ekuguqukeni kobukhulu ngenxa yezinto ezifana notshintsho kubushushu bendalo kunye nokungcangcazela koomatshini, okubangela ukuphambuka kwindawo yokuwelda. I-coefficient yokwandiswa kobushushu beqonga lezemidlalo le-granite yi-(4-8) ×10⁻⁶/℃ kuphela. Idityaniswe nesakhiwo sayo sangaphakathi esixineneyo nesifanayo, ukuzinza kobukhulu be-0.5μm/ngonyaka kunokufezekiswa.
Ukuthatha umgca wokuvelisa imodyuli ye-photovoltaic ye-1GW njengomzekelo, ukuba iqonga eliqhelekileyo lokuhamba liyasetyenziswa, ukuphambuka kwendawo yokuwelda okubangelwa kukuguquguquka kobukhulu kudlula i-0.1mm, okunokubangela ukuba izinga lokuwelda kweeseli zelanga linyuke liye kwi-3%. Xa usebenzisa iiplatifomu zemidlalo ze-granite, izinga lokuwelda linokulawulwa ngaphakathi kwe-0.5%. Kwi-1% nganye yokunciphisa izinga lokuswela, iiseli zebhetri ezingaphezu kwesigidi esinye zinokulondolozwa minyaka le, nto leyo enciphisa ngokuthe ngqo iindleko zemveliso yezinto kwaye ibeke isiseko sokwehla kwexabiso nge-kilowatt-yure nganye.
Ukunciphisa ukugcinwa kwezixhobo rhoqo kunye nokuphucula ukusebenza kakuhle kwemveliso
Iqonga lokushukuma elinozinzo olubi lobukhulu liya kubangela ukuguguleka okukhawulezileyo kwezinto zothumelo kunye nokuchaneka kokubekwa ngenxa yokuguquguquka ngexesha lokusetyenziswa ixesha elide, kwaye ngaloo ndlela lifuna ukulinganiswa nokugcinwa kwezixhobo rhoqo. Amaqonga ezemidlalo egranite, ngozinzo lwawo olubalaseleyo, anokunciphisa ngempumelelo ukwenzeka kweengxaki ezinjalo.
Ngenxa yokwahluka kwayo okuncinci kwe-0.5μm ngonyaka, inqanaba lokuguguleka kwezinto ezibalulekileyo ezifana nendlela yokudlulisa kunye nesenzi sokubeka umatshini wokuwelda umtya lincitshisiwe kakhulu. Ngokwedatha yokulinganisa yokwenyani yeshishini elithile lokuvelisa i-photovoltaic, emva kokwamkela iqonga lokuhamba kwe-granite, umjikelo wokugcinwa komatshini wokuwelda umtya woluliwe ukusuka kanye ngenyanga ukuya kube kanye ngekota, kwaye ixesha lokugcinwa elinye nalo lincitshisiwe ukusuka kwiiyure ezisi-8 ukuya kwiiyure ezi-3. Ukunciphisa ukuphindaphindeka kokugcinwa kwezixhobo kuthetha ukusebenza kakuhle kwemveliso kunye neendleko zokusebenza nokugcinwa kwezixhobo eziphantsi. Ngokusekelwe kumgca wemveliso onomthamo wonyaka we-500MW, unokunyusa ixesha lokuvelisa elisebenzayo malunga neeyure ezingama-200 ngonyaka, uvelise iimodyuli ezininzi ze-photovoltaic ezixabisa ngaphezulu kwe-5 yezigidi zeeyuan, kwaye unciphise kakhulu iindleko nge-kilowatt-yure nganye.
Yandisa ubomi benkonzo yezixhobo kwaye unciphise iindleko zotyalo-mali
Iindleko zotyalo-mali lwezixhobo zokuvelisa i-photovoltaic ziphezulu, kwaye ubomi benkonzo yezixhobo buchaphazela ngokuthe ngqo imbuyekezo kutyalo-mali lwamashishini. Ngenxa yotshintsho oluhlala ixesha elide kunye nokuguquguquka kwesakhiwo, amaqonga aqhelekileyo okushukuma adla ngokusilela ukuhlangabezana neemfuno zemveliso echanekileyo kakhulu kangangeminyaka engaphezu kwemihlanu. Ngenxa yoko, amashishini kufuneka atshintshe izixhobo kwangaphambili, nto leyo enyusa uxinzelelo lotyalo-mali lwezinto ezisisigxina.
Iiplatifomu zemidlalo zegranite, ezineempawu zazo zomzimba nezizinzileyo kunye neekhemikhali, zinokugcina ukuchaneka okuphezulu ngexesha lokusetyenziswa ixesha elide kwaye zandise ngokufanelekileyo ubomi benkonzo iyonke yomatshini wokuwelda intambo. Idatha evela kumenzi wezixhobo ezithile ze-photovoltaic ibonisa ukuba umatshini wokuwelda intambo oxhotyiswe ngeplatifomu yokuhamba yegranite usenokugcina ukuchaneka kokubeka intsimbi ngaphakathi kwe-±0.1mm emva kokusetyenziswa ngokuqhubekayo iminyaka esi-8, ukuhlangabezana neemfuno zemveliso yezinto ezisebenzayo kakhulu. Ngokwahlukileyo koko, izixhobo ezisebenzisa iiplatifomu eziqhelekileyo zokuhamba kufuneka zitshintshwe izinto zazo eziphambili okanye umatshini wonke uphuculwe emva kweminyaka emihlanu. Ukwandiswa kwexesha lenkonzo yezixhobo kwenza ukuba iindleko zotyalo-mali lwe-asethi esisigxina zamashishini zabelwe ixesha elide, nto leyo enciphisa ngakumbi inxalenye yokwehla kwexabiso lezixhobo kwixabiso nge-kilowatt-yure nganye.
Ukuququzelela ukuveliswa kwezinto ezisebenzayo kunye nokwandisa ingeniso yokuveliswa kombane
Uzinzo oluyimilinganiselo ye-0.5μm/ngonyaka lubonelela ngesiqinisekiso sokuba umatshini wokuwelda wentambo ye-photovoltaic ufezekise ukuwelda okuchanekileyo, okuvumela amashishini ukuba avelise iimodyuli ze-photovoltaic ngokusebenza kakuhle. Kwizicelo zesikhululo samandla esisebenzayo, izinto ezisebenzayo kakhulu zinokufikelela kumandla aphezulu okuvelisa umbane kunye nezinga eliphantsi lokunciphisa umbane, ngaloo ndlela kuphucula ingeniso iyonke yokuvelisa umbane yesikhululo samandla.
Umzekelo, iimodyuli zeglasi ezimbini ezimacala mabini ezine-welding echanekileyo kakhulu zinokunyusa ukusebenza kakuhle kokuveliswa kombane nge-3% ukuya kwi-5% xa kuthelekiswa neemodyuli eziqhelekileyo. Thatha isikhululo samandla se-photovoltaic se-100MW njengomzekelo. Ngokusebenzisa izixhobo ezisebenzayo kakhulu, inokuvelisa umbane owongezelelweyo ozii-kilowatt-hours ezi-3 ukuya kwezi-5 zezigidi ngonyaka. Ukunyuka kwengeniso yokuveliswa kombane kuthetha ukwehla okulinganiselweyo kwindleko nge-kilowatt-hour nganye, nto leyo ephucula ngakumbi uqoqosho kunye nokukhuphisana kwezikhululo zamandla ze-photovoltaic.
Iqonga le-granite motion elinikezelwe kwiimashini zokudibanisa iintambo ze-photovoltaic, ezinozinzo oluyi-0.5μm/ngonyaka njengenzuzo yalo ephambili, linciphisa ngokupheleleyo iindleko zemveliso yeemodyuli ze-photovoltaic kunye neendleko nge-kilowatt-yure nganye yezikhululo zamandla ngeendlela ezininzi ezinje ngokuqinisekisa ukuchaneka kwe-welding, ukunciphisa ukugcinwa kwezixhobo, ukwandisa ubomi bezixhobo, kunye nokwenza lula ukuveliswa kwezinto ezisebenzayo. Libonelela ngenkxaso yobugcisa eqinileyo kushishino lwe-photovoltaic ukuze kufezekiswe "ukulingana kwegridi" kunye nophuhliso oluzinzileyo.
