Enye indlela yokunciphisa ubungakanani bentambo kukusebenzisa iitafile ezithile ezibonelelwa yi-IEEE, ezibonelela ngeetafile ezininzi ze-100% kunye ne-75% yokulayisha.
Ngokugxila okukhulayo kumandla ahlaziyekayo, amandla elanga azuze amandla amakhulu kwihlabathi jikelele. Njengoko imfuno yofakelo lwelanga iqhubeka isanda, kubalulekile ukukhulisa yonke imiba yeprojekthi yelanga ukukhulisa imbuyekezo yayo. I-Photovoltaic cabling yindawo ehlala ingahoywa enesakhono esikhulu sokuphucula.
Ukukhethwa kwentambo ye-Photovoltaic kunye nobukhulu budlala indima ebalulekileyo ekuqinisekiseni ukuhanjiswa kwamandla ngokufanelekileyo ngelixa kuncitshiswa iindleko zokufakela. Ngokwemveli, iintambo ziye zagqithiswa ukuba ziphendule ukuhla kwamandla ombane, ukuqinisekisa ukhuseleko kunye nokuthobela imimiselo. Nangona kunjalo, le ndlela inokukhokelela kwiindleko ezingeyomfuneko, inkcitho yezinto eziphathekayo, kunye nokunciphisa ukusebenza kwenkqubo. Ukujongana nale mingeni, iinjineli kunye nabaphuhlisi ngoku baguqukela kwiindlela ezintsha, ezinjengokusebenzisa iitheyibhile ezithile ezibonelelwe yi-IEEE, ukunciphisa ngokukhuselekileyo ubungakanani bentambo kunye nokwandisa imbuyekezo yeprojekthi.
I-IEEE (Iziko leeNjineli zoMbane kunye nezoMbane) ibonelela ngezikhokelo kunye nemigangatho ebanzi yoyilo, ukufakwa, kunye nokusebenza kweenkqubo zamandla elanga. Kwi-IEEE 1584-2018 yabo eyaziwayo "Izikhokelo zokuSebenza i-Arc Flash Hazard Calculations," babonelela ngeetheyibhile ezininzi ukukunceda ukugqiba i-cable sizing ye-100% kunye ne-75% iimeko zomthwalo. Ngokusebenzisa ezi tafile, abaqulunqi kunye nabafakeli banokumisela ngokuchanekileyo ubungakanani bekhebula elifanelekileyo ngokusekelwe kwiimfuno ezithile kunye neeparitha zeprojekthi yelanga.
Enye yeenzuzo ezibalulekileyo zokusebenzisa ezi tafile kukukwazi ukunciphisa ngokukhuselekileyo ubungakanani bentambo ngaphandle kokuchaphazela ingqibelelo yenkqubo. Ngokuqwalasela izinto ezinje ngemathiriyeli ye-conductor, ukukala ubushushu, kunye neemfuno zokuhla kwamandla ombane, abaqulunqi banokuluphucula ulwakhiwo lweengcingo ngelixa bethobela imigangatho nemimiselo yokhuseleko. Ukuncitshiswa kobungakanani bekhebula kunciphisa iindleko zezinto eziphathekayo kwaye kwandisa ukusebenza kakuhle kwenkqubo yonke, okukhokelela kukongiwa kweendleko ezithe ngqo.
Olunye uqwalaselo olubalulekileyo kwi-PV cabling optimization kukudityaniswa kobuchwepheshe obukrelekrele. Ukonyusa ukusebenza kunye nokuguquguquka kweenkqubo zelanga, ukufakwa okuninzi ngoku kufaka izilungisi zamandla kunye ne-microinverters. Ezi zixhobo zandisa ukuveliswa kwamandla ngokunciphisa imiphumo yezithunzi, uthuli kunye nezinye izinto eziphazamisa ukusebenza. Xa zidityaniswe nezibonelelo zokulinganisa iintambo eziphuculweyo, ezi nkqubela phambili zinokuyandisa ngakumbi imbuyekezo yeprojekthi ngokwandisa imveliso yamandla kunye nokunciphisa iindleko zokulondolozwa.
Ukuqukumbela, ukwenziwa kweecabling ze-PV yinkalo ebalulekileyo yocwangciso lweprojekthi yelanga kwaye kunokuchaphazela kakhulu imbuyekezo. Ngokusebenzisa iitheyibhile ezithile ezibonelelwe yi-IEEE kunye nokuqwalasela izinto ezifana nokuhla kwamandla ombane, ukhetho lwemathiriyeli, kunye nokudibanisa inkqubo, abaqulunqi kunye nabafakeli banokuwunciphisa ngokukhuselekileyo ubungakanani bentambo ngelixa behlangabezana nemigangatho yokhuseleko kunye nemimiselo. Le ndlela inokubangela ukongiwa kweendleko ezibalulekileyo, ukuphucula ukusebenza kakuhle kwenkqubo kunye nokwanda kwemveliso yamandla. Njengoko ishishini lelanga liqhubeka nokuguquka, ukulungiswa kwe-photovoltaic cabling kufuneka kubekwe phambili ukuze kuvulwe amandla apheleleyo elanga kunye nokukhawulezisa ukutshintshela kwikamva elizinzileyo.
