Ukusetshenziswa Kwamaphaneli Elanga Emakhaya
Ukusetshenziswa kwamaphaneli elanga emakhaya kuye kwaba yinto ethandwa kakhulu eminyakeni yamuva nje. Ukwenyuka kwamazinga kagesi, ukuqwashisa ngemvelo okwandayo, kanye nentuthuko kwezobuchwepheshe kwenze amandla elanga aba yindlela ewusizo kakhulu yezidingo zasekhaya. Amaphaneli elanga avumela abanikazi bezindlu ukuthi bakhiqize ugesi wabo ngokukhanya kwelanga, okunciphisa ukuthembela kugridi kagesi evamile, futhi ngokuhamba kwesikhathi, kunciphisa izindleko zanyanga zonke. Kodwa-ke, ukufaka amaphaneli elanga akuyona into okufanele ithathwe kalula, njengoba kudinga izibalo zobuchwepheshe, izindleko zokuqala, kanye nokulungiswa kwemikhuba yokusebenzisa amandla.
Ayini amaphaneli elanga futhi asebenza kanjani?
Amaphaneli elanga, noma amamojula e-photovoltaic (PV), amadivayisi aguqula ukukhanya kwelanga kube ugesi. Le nqubo yenzeka ngamaseli elanga enziwe ngezinto ze-semiconductor (ngokuvamile i-silicon). Lapho ukukhanya kushaya amaseli, ama-electron ayahamba, akhiqize ugesi oqondile (DC). Ukuze kunikwe amandla izinto zasekhaya, ugesi we-DC ube usuguqulwa ube ugesi oshintshashintshayo (AC) kusetshenziswa i-inverter.
Ezinhlelweni zokuhlala, amaphaneli elanga avame ukufakwa ophahleni nge-engeli ethile kanye ne-engeli ukuze athole ukuchayeka kwelanga okuhle kakhulu. Ugesi okhiqizwayo ungasetshenziswa ngokushesha, ugcinwe kumabhethri (ezinhlelweni zebhethri), noma ufakwe kugridi kagesi (ezinhlelweni ezixhunywe kugridi), kuye ngohlobo lwesistimu ekhethiwe.
Izinhlobo zezinhlelo zamaphaneli elanga emakhaya
Ngokuvamile, kunezinhlobo ezintathu zezinhlelo zamaphaneli elanga ezivame ukusetshenziselwa izindlu zokuhlala:
1. Uhlelo oluku-grid (oluxhunywe kunethiwekhi)
Lolu hlelo luxhunywe kugridi kagesi ye-PLN. Uma amaphaneli elanga ekhiqiza ugesi, ikhaya liwusebenzisa kuqala. Uma kukhona ukukhiqizwa okweqile, amandla angathunyelwa kugridi (kuye ngemithethonqubo nezinhlelo ezisebenzayo). Ebusuku noma lapho ukukhiqizwa kwehla, ikhaya lidonsa ngokuzenzakalelayo ugesi ku-PLN. Inzuzo izindleko eziphansi ngoba alidingi amabhethri. Inkinga ukuthi lapho ugesi we-PLN ucima, uhlelo olukugridi luvame ukuvala ngenxa yezizathu zokuphepha.
2. Uhlelo olungaphandle kwegridi (oluzimele)
Lolu hlelo aluxhunyiwe enkampanini kagesi kahulumeni (i-PLN) futhi luthembele kumaphaneli elanga namabhethri njengomthombo walo wamandla oyinhloko. Lufanelekela izindawo ezikude ezingenawo ugesi noma izindawo ezibhekana nokuphazamiseka kukagesi njalo. Inzuzo ukuzimela kwamandla, kodwa inkinga izindleko eziphakeme ngenxa yesidingo samabhethri kanye nokuhlela amandla okunamandla okuqinile.
3. Uhlelo lwe-hybrid
Uhlelo oluhlanganisiwe luhlanganisa amandla asebenza kugridi kanye namandla ebhethri. Izindlu zingasebenzisa ugesi ovela kumaphaneli elanga, zigcine amandla amaningi emabhethri, futhi zihlale zixhunywe enkampanini kagesi kahulumeni (i-PLN) njengesipele. Lolu hlelo lunikeza ukuguquguquka okukhulu, ikakhulukazi emakhaya adinga amandla okusekela ngesikhathi sokucima kukagesi. Kodwa-ke, izindleko zokuqala zivame ukuba phezulu kunezinhlelo ezisebenza kugridi.
Izinzuzo zamaphaneli elanga emakhaya
Inzuzo esobala kakhulu yamaphaneli elanga ukonga ugesi. Ngokukhiqiza ugesi wakho, unganciphisa ukusetshenziswa kukagesi kwakho enkampanini kagesi kahulumeni (i-PLN). Ezindaweni ezinamandla aphezulu okukhanya kwelanga, ukonga kungaba kukhulu, ikakhulukazi uma ikhaya lakho lisebenzisa ugesi omningi, njengesiphephetha-moya, amaphampu amanzi, iziqandisi ezinkulu, noma izinto zikagesi ezisebenza isikhathi eside.
Ngaphezu kwalokho, amaphaneli elanga nawo anikeza izinzuzo zemvelo. Amandla elanga angumthombo wamandla avuselelekayo ongakhiqizi ukukhishwa kwekhabhoni uma esetshenziswa. Uma amakhaya amaningi eshintshela kumaphaneli elanga, umthelela ohlangene ekunciphiseni ukukhishwa kwekhabhoni ungaba mkhulu.
Enye inzuzo ukwanda kwenani lempahla. Izindlu ezinamaphaneli elanga zivame ukubonwa njengezesimanje futhi ezisebenzisa kahle ugesi, okungase kudonsele abathengi abangaba khona. Kwezinye izindawo, ukuba khona kwamaphaneli elanga kungaba yindawo ebalulekile yokuthengisa ekhaya, ikakhulukazi uma uhlelo lunakekelwa kahle futhi lunamandla anele.
Izinto okufanele uzicabangele ngaphambi kokufakwa
Ngaphambi kokufaka amaphaneli elanga, kunezici eziningana ezibalulekile okufanele uzihlole. Okokuqala, cabanga ngesimo nosayizi wophahla lwakho. Uphahla kumele lube banzi ngokwanele, luqine, futhi lube nokufinyelela okuhle elangeni. Umthunzi ovela ezihlahleni, ezakhiweni eziseduze, noma kwezinye izakhiwo unganciphisa kakhulu ukukhiqizwa kukagesi. Ngakho-ke, ukuhlola indawo ngokuvamile kuyadingeka ukuze kubalwe ukukhiqizwa kwamandla okungenzeka.
Okwesibili indlela yokusetshenziswa kukagesi ekhaya. Izindlu ezisebenzisa ugesi omningi emini zivame ukuzuza kakhulu ekusetshenzisweni kukagesi wephaneli yelanga ngqo. Uma ukusetshenziswa kukagesi kwenzeka kakhulu ebusuku, uhlelo lwebhethri noma ukuphathwa kokusetshenziswa kubalulekile ukuqinisekisa ukusetshenziswa kahle kwephaneli yelanga.
Okwesithathu umthamo wesistimu. Umthamo wephaneli yelanga uvame ukuvezwa ku-kWp (kilowatt-peak). Uma umthamo uphakeme, kulapho ukukhiqizwa kukagesi kukhuphuka khona, kodwa futhi nezindleko zokufaka ziphakeme. Ukunquma umthamo ofanele kudinga ukucabangela ibhili yakho kagesi yanyanga zonke, umthamo ofakiwe, kanye nemigomo yokonga.
Okwesine isabelomali sokuqala sezindleko. Ukufaka amaphaneli elanga kudinga ukutshalwa kwezimali kokuqala, okuhlanganisa amaphaneli, i-inverter, isakhiwo sohlaka, izintambo, amadivayisi okuvikela, kanye nezindleko zokufaka. Izinhlelo zebhethri zibiza kakhulu ngoba amabhethri ayizingxenye ezibizayo futhi anempilo elinganiselwe.
Inqubo yokufaka nokulungisa
Ukufakwa kwamaphaneli elanga kufanele kwenziwe ngumhlinzeki wesevisi onolwazi, oqinisekisiwe, noma othembekile. Le nqubo ihlanganisa ukuhlola, ukwakheka kwesistimu, ukufakwa kohlaka namaphaneli, ukufakwa kwe-inverter, izintambo, kanye nokuhlolwa kwesistimu. Uma uhlelo luxhunywe enkampanini kagesi kahulumeni (i-PLN), izinqubo ezengeziwe ngokuvamile zihilela ukuthola izimvume nokufaka imitha ekhethekile, njengoba kudingeka ngokomthetho.
Ngokuphathelene nokugcinwa, amaphaneli elanga kulula ukuwanakekela. Ukukhathazeka okuyinhloko ukuqinisekisa ukuthi indawo yephaneli ayinawo uthuli oluningi, amaqabunga, noma imfucumfucu engavimbela ukumuncwa kokukhanya. Ezindaweni ezinemvula eyanele, ukuhlanza kwemvelo kuvamile, kodwa ukuhlanza ngesandla njalo kusanconywa. Ngaphezu kwalokho, ama-inverter adinga ukubhekwa, njengoba eyizingxenye ze-elekthronikhi ezisebenza njalo. Ama-inverter amaningi anamuhla anezinhlelo zokusebenza zokuqapha ukuqapha ukukhiqizwa kwamandla kwansuku zonke nokuthola ukungasebenzi ngokushesha.
Izinselele nezithiyo ezivame ukuhlangana nazo
Inselele enkulu yizindleko zokutshalwa kwezimali kokuqala, eminye imindeni esazibona ziphezulu. Nakuba ukonga kutholakala ngokuhamba kwesikhathi, akuwona wonke umuntu okulungele ukufaka imali enkulu kangaka ekuqaleni. Enye inselele izinguquko ezinqubweni zokungenisa nokuthumela ugesi kwamanye amazwe, ezingathinta inzuzo yezinhlelo zegridi.
Izimo zezulu nazo ziyimbangela. Ngesikhathi semvula noma isimo sezulu esinamafu isikhathi eside, ukukhiqizwa kukagesi kungancipha. Ngakho-ke, ukuhlela kumele kube ngokoqobo: amaphaneli elanga awasho ugesi wamahhala ongenamkhawulo, kodwa kunalokho umthombo owengeziwe onciphisa ukusetshenziswa okuvela kugridi.
Isiphetho
Amaphaneli elanga ayisisombululo samandla esibaluleke kakhulu emakhaya. Ngokusebenzisa ukukhanya kwelanga, abanikazi bezindlu banganciphisa izikweletu zikagesi, banciphise umthelela wekhabhoni yabo, futhi bandise ukuzimela kwamandla. Kodwa-ke, isinqumo sokufaka sidinga ukuhlela ngokucophelela mayelana nohlobo lwesistimu, isimo sophahla, amaphethini okusetshenziswa kukagesi, kanye nesabelomali. Ngokufakwa okufanele kanye nokulungiswa okulula, amaphaneli elanga angaba utshalomali lwesikhathi eside oluzuzisa kokubili ngokwezomnotho nangokwemvelo emndenini.
