Iindaba

Ixabiso eliphantsi leentambo alifane libe yintambo ebiza kakhulu ebomini besakhiwo. Kwiinkqubo zombane zorhwebo nezemizi-mveliso, ukhetho lomqhubi aluchaphazeli nje kuphela uhlahlo lwabiwo-mali lokuthenga kodwa luchaphazela nomsebenzi wokufakela, ubungakanani beentambo, ukupheliswa, iinkqubo zokulungisa, ukulahleka kwamandla, ukutyholwa ngobusela, kunye nexabiso lokubuyisela ubomi.

Njengoko iiprojekthi zokugcina amandla elanga kunye nombane zisanda ukusuka eluphahleni ukuya kwiindawo zokutshaja zorhwebo, ukuthembeka koqhagamshelo ngalunye lwe-DC kuba yingxaki yokhuseleko kunye nokusebenza kwangaphambili.

Ukukhetha umthengisi wekhebula le-DC elisebenzisa i-photovoltaic kwiprojekthi yelanga yemizi-mveliso sisigqibo sobuchwephesha nesorhwebo esinemiphumo yexesha elide. Umgangatho wekhebula unefuthe kukhuseleko, isivuno samandla, ubuninzi bokugcinwa, kunye nokuthobela yonke ibhalansi yenkqubo, nangona imele isabelo esincinci seendleko zeprojekthi iyonke. Eli nqaku lichaza into eyahlula umenzi wekhebula lelanga okwinqanaba eliphezulu, ukusuka ekukhetheni izinto kunye nemigangatho yesatifikethi ukuya ekuhambelaneni kwemveliso, amandla okuvavanya, kunye nokuthembeka kokuhanjiswa. Ekugqibeleni, uya kuba nesakhelo esisebenzayo sokuthelekisa ababoneleli kunye nokunciphisa umngcipheko wokuthengwa kwiindawo zombane kunye nokufakelwa okukhulu kwezorhwebo.

Njengoko iiprojekthi ze-photovoltaic zikhula ngokukhawuleza kwaye zisebenza kwiindawo ezinzima, ukusebenza kwento nganye kubalulekile—ingakumbi iziseko zekhebula ezithwala amandla e-DC kulo lonke uluhlu. Intlanganiso yakutshanje yeshishini lelanga le-PNTTECH ihlanganise abathunywa abangaphezu kwama-250, iinjineli, ababoneleli, kunye neenkokheli zoshishino ukuze bahlole indlela engcono yoyilo lwenkqubo enokuphucula ngayo ukusebenza kakuhle, ukuqina, kunye nexabiso leprojekthi yexesha elide. Iingxoxo zigxile kwinkqubela phambili ebonakalayo efana noyilo lwe-1500V DC, olunokunciphisa ukulahleka kwamandla ukuya kuthi ga kwi-2.5%, kunye nemfuno ekhulayo ye intambo yelanga izisombululo ezinokumelana nokuvezwa yi-UV, ukufuma, kunye namaqondo obushushu ukusuka kwi--40°C ukuya kwi-+90°C kwiminyaka engama-25 yobomi benkonzo.

Imakethi yelanga eMzantsi-mpuma Asia itshintsha ukusuka ekufakweni ngokukhawuleza ukuya kuyilo lwenkqubo olukrelekrele noluzinzileyo—kwaye ukukhethwa kweentambo ngoku yinxalenye ephambili yolo tshintsho. KwiMboniso yoLondolozo lwaMandla elanga yaseVietnam ka-2026 eHo Chi Minh City, I-PNTECH kubonwe imfuno enamandla ye-voltage ephezulu, ilahleko ephantsi intambo yelanga izisombululo ezakhelwe ubushushu, ukufuma, kunye neendawo ezinkulu zorhwebo. Njengoko kukho ababonisi abangaphezu kwama-450 kunye neengcali zoshishino eziqikelelwa kwi-15,000 ezazikho, lo msitho unike umbono ocacileyo wendlela iinjongo zePDP8 zaseVietnam ezitshintsha ngayo izigqibo zeBalance of System. Esi sishwankathelo sigxininisa iinkcukacha zekhebula, ubungakanani bomqhubi, kunye nokukhethwa kwezinto ezibaluleke kakhulu ekusebenzeni kwePV okuthembekileyo.

Kubathengi belanga be-B2B, izihlanganisi azisezona nxalenye zincinci zokulinganisela inkqubo; zizinto ezinomngcipheko ophezulu, ezibalulekileyo ekusebenzeni ezichaphazela ukhuseleko, ixesha lokusebenza, ukuthobela imithetho, kunye nembuyekezo yexesha elide yeprojekthi. Njengoko iinkqubo ze-PV zoncedo kunye nezentengiso zisiya kuyilo lwe-voltage ephezulu, ukukhetha izihlanganisi ezifanelekileyo ezihambelana ne-MC4 kufuna okungaphezulu kokujonga ixabiso kunye novavanyo lwangoku. Abathengi kufuneka baqonde iingozi zokusebenzisana, umgangatho wezinto, imigangatho yesatifikethi, ukuqina kwendalo, kunye nokungaguquguquki kwabathengisi kwiindawo ezinkulu zokusasazwa. Esi sikhokelo sichaza izinto ezibalulekileyo zobugcisa kunye nokuthengwa kwezinto ngo-2026, sinceda ii-EPC, abaphuhlisi, kunye namaqela okufumana izinto ukuba benze izigqibo ezinolwazi zokudibanisa ezinciphisa umngcipheko wokungaphumeleli, zikhusele iziqinisekiso, kwaye zixhase ukusebenza kweeasethi okuthembekileyo.

Iintambo ze-DC ze-photovoltaic ezinokuthenjwa azichazwa ngokweenkcukacha zodwa; ukusebenza kwazo ngokwenene kuxhomekeke kwindlela ezenziwa kwaye zilawulwa ngayo ii-conductors, i-insulation, i-shielding, kunye ne-jacketing kwinqanaba ngalinye lemveliso. Eli nqaku lichaza iindlela zokwenza ezichaphazela kakhulu ukusebenza kakuhle kombane, uzinzo lobushushu, ukumelana nemozulu, kunye nobomi benkonzo ende kufakelo lwelanga. Uza kubona indlela ukukhethwa kwezinto, ukuxhuzula kwe-conductor, ukuchaneka kwe-extrusion, ukudibanisa, kunye novavanyo lomgangatho ezisebenzisana ngayo ukunciphisa ilahleko, ukuthintela ukusilela kwangethuba, kunye nokuhlangabezana neemfuno ezifunekayo ze-1500V DC kunye nokuqina kwangaphandle. Ngeso siseko, ingxoxo ingangena kwiinkqubo ezithile kunye nolawulo oluhlula imveliso yekhebula le-photovoltaic ekumgangatho ophezulu.

Ukuthenga iintambo zolwandiso ze-PV kwiifektri zaphesheya kungazinciphisa iindleko zokulinganisela inkqubo, kodwa ukonga kuxhomekeke kokungaphezulu kokuthelekisa amaxabiso eyunithi. Ukuguquguquka kwezinto, iinkcukacha zentambo, iimfuno zesatifikethi, ubungakanani obuncinci beodolo, izinto ezisetyenziswayo, imisebenzi, kunye nolawulo lomgangatho womthengisi konke kubumba ixabiso lokwenyani lomhlaba kunye nexabiso leprojekthi yexesha elide. Eli nqaku lichaza apho kukho abaqhubi beendleko ezinkulu, indlela amaqela okuthenga anokuziphepha ngayo iindleko ezifihlakeleyo, kunye neendlela zokufumana ezinceda ukukhusela zombini iimali kunye nokusebenza. Ekugqibeleni, abafundi baya kuba nesakhelo esisebenzayo sokuvavanya ababoneleli baphesheya, ukuxoxisana ngempumelelo ngakumbi, kunye nokunciphisa iindleko zentambo ngaphandle kokunyusa umngcipheko wobugcisa okanye wokuthobela umthetho.

Izihlanganisi zelanga zisenokuba zincinci, kodwa kwiinkqubo ze-PV zanamhlanje zithwala amandla e-DC aphezulu nge-voltage kwiminyaka emininzi yobushushu, ukubanda, ukuvezwa kwe-UV, ukufuma, ityuwa, kunye nongcoliseko lweekhemikhali. Ukuqina kwazo kuchaphazela ngokuthe ngqo ukhuseleko, imveliso yamandla, kunye neendleko zokugcinwa kwexesha elide, ngakumbi kwiindawo zokusetyenziswa kunye nokufakelwa kwezorhwebo apho uqhagamshelo olunye olubuthathaka lunokuphazamisa umtya wonke. Eli nqaku lihlola uxinzelelo lokusingqongileyo olujongene nezihlanganisi zelanga, izixhobo kunye namaqhinga okutywina azinceda ukuba zixhathise ukuguga kunye nokugqwala, kunye neendlela zokungaphumeleli ezibonakala xa ezo zikhuselo zingaphumeleli, zibonelela ngesiseko esisebenzayo sokuvavanya ukuthembeka kwesihlanganisi kwiimeko zentsimi ezifuna amandla.
