Enye indlela yokunciphisa usayizi wekhebula ukusebenzisa amathebula athile anikezwa yi-IEEE, ahlinzeka ngamatafula amaningi okulayisha okungu-100% no-75%.
Njengoba kugxilwe kakhulu emandleni avuselelekayo, amandla elanga athole umfutho omkhulu emhlabeni jikelele. Njengoba isidingo sokufakwa kwamandla elanga siqhubeka nokukhula, kubalulekile ukwenza ngcono zonke izici zephrojekthi yelanga ukuze kwandiswe inzuzo yayo. Ukufakwa kwezintambo ze-photovoltaic kuyindawo evame ukunganakwa enethuba elikhulu lokuthuthuka.
Ukukhethwa kwekhebula le-photovoltaic kanye nosayizi kudlala indima ebalulekile ekuqinisekiseni ukudluliselwa kwamandla okuphumelelayo ngenkathi kunciphisa izindleko zokufaka. Ngokwesiko, izintambo bezilokhu zinkulu kakhulu ukuze kubhekwe ukwehla kwamandla kagesi, kuqinisekiswe ukuphepha futhi kuhambisane nemithethonqubo. Kodwa-ke, le ndlela ingabangela izindleko ezingadingekile, ukuchithwa kwezinto ezibonakalayo, kanye nokusebenza kohlelo okuncishisiwe. Ukuze babhekane nalezi zinselele, onjiniyela nabathuthukisi manje sebephendukela ezindleleni ezintsha, njengokusebenzisa amathebula athile anikezwe yi-IEEE, ukuze banciphise ngokuphephile usayizi wekhebula futhi bathuthukise ukubuyiselwa kwephrojekthi.
I-IEEE (Institute of Electrical and Electronics Engineers) inikeza iziqondiso nezindinganiso eziphelele zokuklama, ukufaka, kanye nokusebenza kwezinhlelo zamandla elanga. Ku-IEEE 1584-2018 “Iziqondiso Zokwenza Ukubalwa Kwengozi Ye-Arc Flash,” banikeza amathebula amaningi ukusiza ekunqumeni usayizi wekhebula wezimo zomthwalo ongu-100% no-75%. Ngokusebenzisa lawa mathebula, abaklami nabafaki banganquma ngokunembile usayizi wekhebula ofanele ngokusekelwe ezidingweni ezithile kanye nemingcele yephrojekthi yelanga.
Enye yezinzuzo ezibalulekile zokusebenzisa lawa mathebula yikhono lokunciphisa usayizi wekhebula ngokuphephile ngaphandle kokuthinta ubuqotho bohlelo. Ngokucabanga ngezinto ezifana nezinto zokuqhuba, izilinganiso zokushisa, kanye nezidingo zokwehla kwamandla kagesi, abaklami bangenza ngcono ukwakheka kwezintambo ngenkathi besalandela amazinga nemithetho yokuphepha. Ukwehla kosayizi wekhebula kunciphisa izindleko zezinto futhi kwandisa ukusebenza kahle kohlelo lonke, okuholela ekongeni okukhulu kwezindleko eziqondile.
Okunye okubalulekile okufanele kucatshangelwe ekwenzeni ngcono izintambo ze-PV ukuhlanganiswa kobuchwepheshe obuhlakaniphile. Ukuze kwandiswe ukusebenza nokuguquguquka kwezinhlelo zelanga, ukufakwa okuningi manje kunezithuthukisi zamandla kanye nama-microinverter. Lawa madivayisi andisa ukukhiqizwa kwamandla ngokunciphisa imiphumela yezithunzi, uthuli nezinye izinto eziwohloza ukusebenza. Uma kuhlanganiswa nezinzuzo zobukhulu bekhebula obuthuthukisiwe, lokhu kuthuthuka kungandisa kakhulu imbuyiselo yephrojekthi ngokukhulisa ukukhiqizwa kwamandla nokunciphisa izindleko zokulungisa.
Ekuphetheni, ukulungiswa kwamakhebula e-PV kuyisici esibalulekile sokuhlela iphrojekthi yelanga futhi kungathinta kakhulu imbuyiselo. Ngokusebenzisa amathebula athile anikezwe yi-IEEE nokucabangela izici ezifana nokwehla kwamandla kagesi, ukukhethwa kwezinto, kanye nokuhlanganiswa kwesistimu, abaklami nabafaki banganciphisa ngokuphephile usayizi wekhebula ngenkathi besahlangabezana nezindinganiso zokuphepha kanye nemithethonqubo. Le ndlela ingaholela ekongeni izindleko okukhulu, ukusebenza kahle kwesistimu okuthuthukisiwe kanye nokukhiqizwa kwamandla okwandisiwe. Njengoba imboni yelanga iqhubeka nokukhula, ukulungiswa kwamakhebula e-photovoltaic kumele kubekwe phambili ukuze kuvulwe amandla aphelele amandla elanga futhi kusheshiswe ukushintshela esikhathini esizayo esiqhubekayo.
