Ukukhetha umthengisi wekhebula le-DC le-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 inqanaba eliphezulu Intambo yelanga umenzi, ukusuka ekukhetheni izinto kunye nemigangatho yesatifikethi ukuya ekuhambelaneni kwemveliso, amandla okuvavanya, kunye nokuthembeka kokuhambisa. Ekugqibeleni, uya kuba nesakhelo esisebenzayo sokuthelekisa ababoneleli kunye nokunciphisa umngcipheko wokuthengwa kwempahla kwiindawo zombane kunye neendawo ezinkulu zorhwebo.
Kutheni Kubalulekile Ukukhetha Umenzi Weentambo Zelanga Ofanelekileyo
Ukuthenga izinto ze-photovoltaic arrays ezisetyenziswa kakhulu kufuna ingqalelo engqongqo kwiinkcukacha, njengoko ukuthembeka kwebhalansi yombane yenkqubo kuchaphazela ngokuthe ngqo inzuzo yexesha elide ye-asethi. Ngelixa iimodyuli ze-photovoltaic kunye nee-inverters zilawula isabelo esikhulu sebhajethi yokuthenga, isiseko sentambo yamandla angoku ngqo (DC) sisebenza njengenkqubo yokujikeleza kwegazi yesityalo sonke samandla. Nangona intambo idla ngokuba yi-1% ukuya kwi-2% yenkcitho iyonke yokuqala, intambo engaphantsi komgangatho inoxanduva lwepesenti engalinganiyo yeempazamo zenkqubo, ukukhanya kwe-arc, kunye nexesha lokungasebenzi elingalindelekanga. Ukukhetha i- iqabane elikhethekileyo lokuvelisa ngoko ke sisizathu esibalulekileyo kunokuba kube yintengiselwano elula yezinto ezithengiswayo.
Ukuchaza iCable yeSolar ekuThengweni kweMizi-mveliso
Kwimeko yokuthengwa kwempahla yemizi-mveliso, ingcali ekhethekileyo Intambo yelangayenziwe ngendlela eyahlukileyo xa ithelekiswa neentambo zombane eziqhelekileyo. Ezi ntambo zenzelwe ngokukodwa I-Interconnect Solar Iiphaneli kunye nokuhambisa umbane ngqo kwiibhokisi zokudibanisa kunye nee-inverters eziphakathi kwiindawo ezinkulu. Iinkcukacha zanamhlanje zoshishino zifuna ukuba ezi ntambo ziphathe ngokukhuselekileyo i-voltage yenkqubo ukuya kuthi ga kwi-1500V DC, umgangatho onciphisa ilahleko zothumelo kwiindawo zokufakelwa kwee-megawatt ezininzi. Amaqela okuthenga kufuneka afumane iintambo ezine-insulation edibeneyo ye-electron-beam, ukuqinisekisa ukuba zinokumelana namashumi eminyaka yokuchatshazelwa ziinguqu ezinobungozi kwindalo. Ezi nguqu ziquka imitha ye-ultraviolet enamandla, ubuninzi be-ozone ephezulu, kunye nokuguquguquka kwemozulu okugqithisileyo okuxhaphakileyo kwiindawo zasentlango, elunxwemeni, okanye kwiindawo ezidadayo zelanga.
Iingozi zorhwebo, zobugcisa, kunye nezokusebenza
Iingozi ezinxulumene nokukhetha iqabane lomenzi eliphantsi zinkulu kwaye zininzi. Ngokwezorhwebo, ukwehla kwe-voltage edlula i-2%—okubangelwa kukungafumani kakuhle kwe-conductor okanye ubumsulwa obuphantsi be-copper—kuthetha ilahleko enkulu yokuveliswa kwamandla aqokelelweyo kwiminyaka engama-25 yobomi beprojekthi eqhelekileyo. Ngokwezobuchwepheshe, izixhobo zokukhusela eziphantsi zisengozini enkulu yokuqhekeka okuncinci, ukungena kwamanzi, kunye nokuwohloka kobushushu. Ezi ngxaki zonyusa kakhulu umngcipheko wokusebenza kweempazamo zomhlaba, ukukhubeka kwe-inverter, kunye nemililo yombane eyingozi. Ukulungisa ezi ngxaki kufuna umsebenzi omkhulu wokuxilonga, ukupheliswa kwamandla enkqubo, kunye neendleko zokutshintsha ezidlula kakhulu nayiphi na imali yokuqala efunyenwe ngokukhetha umthengisi ophantsi.
Iimpawu zobugcisa, ukuthotyelwa kwemithetho, kunye nomgangatho
Ukuvavanya umenzi kufuna uvavanyo lobuchwephesha oluqinileyo lwemigca yemveliso yakhe, ukufumana izinto, kunye neenkqubo zokuqinisekisa umgangatho.

Iziqinisekiso, Uvavanyo, kunye nokulandelelwa
Abavelisi abadumileyo baza kubonelela ngamaxwebhu apheleleyo aqinisekisa ukuba bayayithobela imigangatho yehlabathi engqongqo, ingakumbi i-EN 50618 (echaza uhlobo lwentambo ye-H1Z2Z2-K) kunye ne-UL 4703 kwimarike yaseMntla Melika. Abathengi kufuneka baqinisekise ukuba umthengisi ugcina iziqinisekiso ze-ISO 9001 kunye ne-ISO 14001 ezisebenzayo kwizixhobo zabo zemveliso. Ngaphezu koko, abavelisi abaphezulu baphumeza uvavanyo oluzenzekelayo oluhambelanayo, olufana novavanyo lwe-spark oluphezulu, uvavanyo lokunyamezela kobushushu, kunye nokuskena kwe-laser enobukhulu, ukuqinisekisa ukuba amazinga okusilela kokuvelisa ahlala engaphantsi komlinganiselo we-0.1%. Ukulandelela okupheleleyo kwebhetshi—ukusuka kwintonga yokuqala yobhedu eluhlaza ukuya kwi-spool egqityiweyo, edibeneyo—luphawu olungenakuxoxiswana ngalo lokuqinisekisa umgangatho wemizi-mveliso kunye namabango ewaranti.
Indlela Abathengi Abafanele Bathelekise Ngayo Ababoneleli Beentambo Zelanga
Ngaphaya kweenkcukacha zobugcisa kunye novavanyo lwelabhoratri, amandla orhwebo kunye nokusebenza komenzi amisela ukusebenza kwawo njengeqabane lexesha elide lenkqubo yokubonelela. Iingcali zokuthenga kufuneka zivavanye ababoneleli ngokusekwe kubuchule babo bokuhambisa imithamo ephezulu rhoqo, balawule ubunzima bezinto ezisetyenziswayo, kwaye banikezele ngesakhiwo seendleko esicacileyo nesikhuphisanayo esihambelana nokuxhaswa ngemali kweprojekthi.
Ukufumana izinto, uLogistics, Ixesha lokuKhokela, kunye neXabiso lilonke
Ukuthembeka kwekhonkco lobonelelo kubalulekile ekugcineni ucwangco iishedyuli zokwakha iiprojekthi kunye nokuphepha ukulibaziseka okubizayo. Abathengi bemizi-mveliso kufuneka bahlole amandla emveliso yomenzi kunye noBungakanani beMinimum Order (ii-MOQ), eziqhele ukuba ziikhilomitha ezili-10 ukuya kwezingama-50 kwiikhilomitha ezahlukeneyo, ubukhulu bejakethi ethile, okanye ukubaleka okunemibala. Amaxesha okukhokela lolunye umlinganiselo obalulekileyo; abathengisi benqanaba lokuqala ngokubanzi bagcina ixesha lokutshintsha elithembekileyo leeveki ezi-4 ukuya kwezi-8 ukususela ekukhutshweni kwe-odolo yokuthenga ukuya ekuphumeni kwezibuko. Xa kubalwa iXabiso lilonke lobuNini (i-TCO), abathengi kufuneka baqwalasele ubungakanani bokuthunyelwa, iirhafu zokungenisa impahla, kunye nokuqina kokupakisha. Umzekelo, iidrama zokhuni eziqinisiweyo ziyimfuneko kakhulu ukuthintela umonakalo wokuhamba kwii-odolo ezinzima, ezinkulu ezithunyelwa ngempahla yolwandle.
Inkqubo yokufaneleka koMboneleli
Ukuseka inkqubo yokufaneleka komthengisi eqinileyo kunciphisa umngcipheko wokwenziwa kwezinto kwaye kuqinisekisa ukulungelelaniswa phakathi kwabaphuhlisi beprojekthi kunye nabavelisi. Amaqela okuthenga kufuneka aqalise le nkqubo ngokucela iingxelo zovavanyo lwelebhu ezizimeleyo zomntu wesithathu—ezifana nezo zivela kwi-TÜV Rheinland, i-VDE, okanye i-UL—ukuze ziqinisekise ngokuzimeleyo amaphepha edatha angaphakathi omenzi. Iprotokholi yokufaneleka kufuneka ibandakanye nophicotho olupheleleyo lwefektri ukuze kuhlolwe ngokwasemzimbeni oomatshini bokukhupha, iinkqubo zokuzoba ubhedu, kunye neemeko zokugcina izinto eziluhlaza. Okokugqibela, ukuhlalutya uzinzo lwezemali lomthengisi, ukunamathela kwabo ekuthobeleni urhwebo lwamazwe ngamazwe, kunye nerekhodi yabo yokuthumela. iimveliso ze-multi-megawatt kwiindawo ezifanayo zemozulu zibonelela ngokuzithemba okufunekayo ekunikezeni iikhontrakthi zokuthenga ezinkulu.
