Abantu abaningi banombono wokusebenzisa amaphaneli elanga ukukhiqiza amandla, kodwa abangane abaningi basenokuqonda okungacacile kokuphehlwa kwamandla elanga.Ngakho-ke, yiziphi izinhlobo zamandla elanga akhona?
Ngokuvamile, izinhlelo zokuphehla amandla elanga zingahlukaniswa zibe izigaba ezintathu, okuhlanganisa amasistimu akugridi anikezela amandla kugridi, amasistimu angaphandle kwegridi angaxhumekile kugridi, kanye nezinhlelo ezixubile ezingaxhunywa ngokukhululekile kugridi noma cha. .Uhlelo ngalunye lunesakhiwo nezici zalo.
Isistimu ye-on-grid yakhiwe amaseli e-photovoltaic kanye nama-inverters akugridi.Amandla afakwa ngokuqondile kugridi yomphakathi nge-inverter ekugridi ngaphandle kwesitoreji samandla ebhethri.Njengeziteshi zikagesi eziphansi, uphahla lwezimboni nohwebo, njll. Inhloso ivamise ukudayisela abaqhubi begridi ugesi ukuze bathole inzuzo.
Amasistimu axhunywe kwigridi angaphinde ahlukaniswe abe amasistimu asabalalisiwe naphakathi nendawo.
Ukukhiqizwa kwamandla we-photovoltaic okusatshalaliswa kubhekisela ezikhungweni zokuphehla amandla e-photovoltaic ezakhiwe eduze kwabasebenzisi futhi zisebenza ngendlela yokuzisebenzisela, ukudluliswa kwamandla engeziwe kugridi noma ukudluliselwa ngokugcwele kugridi, futhi kubonakala ngokulungiswa okulinganiselayo ohlelweni lokusabalalisa amandla.Ukuxhuma kugridi yamandla ku-220V, 380V, kanye namazinga angu-10kv akukwazi nje ukwandisa ngempumelelo ukukhiqizwa kwamandla wezitshalo zamandla e-photovoltaic esikalini esifanayo, kodwa futhi nokuxazulula ngokuphumelelayo inkinga yokulahlekelwa amandla ekuthuthukiseni nasekuthuthweni okude.
Isiteshi samandla se-photovoltaic esixhunywe kugridi enkulu esimaphakathi sisho ukusetshenziswa kweziteshi ezinkulu zamandla e-photovoltaic ngendlela ephakathi nendawo evamise ukwakhiwa yizwe.Isiteshi samandla se-photovoltaic esixhunywe kugridi enkulu esimaphakathi ngokuvamile siyisiteshi samandla esisezingeni likazwelonke.Isiteshi sikagesi esiphakathi nendawo sinesilinganiso esikhulu kanye nokuphehla ugesi okuphezulu.
Isistimu ye-off-grid yakhiwe ngamaphaneli elanga, izilawuli, ama-inverter, amaphakethe ebhethri kanye nezinhlelo zokusekela.Ibonakala ngephakethe lebhethri lokugcina amandla, elifanele izindawo lapho ingekho igridi noma amandla axhumeke kugridi angazinzile.Isibonelo, izinhlelo zasendlini kanye nezohwebo zokuhlinzeka amandla okugcina amandla elanga, izibani zasemgwaqweni zelanga, amandla kagesi welanga, izibali zelanga, amashaja omakhalekhukhwini elanga, njll.
IHybrid system, eyaziwa nangokuthi i-off-grid system
Inomsebenzi wokusebenza okuzenzakalelayo kokushintshwa kwezindlela ezimbili.Okokuqala, lapho uhlelo lokukhiqiza amandla e-photovoltaic lunganele ekukhiqizeni amandla ngenxa yamafu, izinsuku zemvula kanye nokuhluleka kwayo, isishintshi singashintsha ngokuzenzakalelayo ohlangothini lokunikezwa kwamandla kwegridi, futhi igridi yamandla inikeza amandla kumthwalo;okwesibili, lapho igridi yamandla ihluleka ngokuzumayo ngenxa yesizathu esithile, Isistimu ye-photovoltaic ingakwazi ukuhlukanisa ngokuzenzakalelayo negridi yamandla, futhi ibe yisimo sokusebenza sesistimu yokukhiqiza amandla e-photovoltaic ezimele.Amanye amasistimu okukhiqiza amandla e-photovoltaic ohlobo lokushintshwa anganqamula uma kunesidingo, futhi anikeze amandla emithwalo evamile, futhi axhume ukunikezwa kwamandla kumthwalo ophuthumayo.Ngokuvamile amasistimu okukhiqiza amandla angekho kugridi ahlonyiswa ngamadivaysi okugcina amandla.
