Wake wabheka isikweletu sakho sikagesi, kungakhathaliseki ukuthi wenzani, sibonakala siphakeme ngaso sonke isikhathi, futhi wacabanga ngokushintshela kumandla elanga, kodwa ungazi ukuthi ungaqala kuphi?
I-Dawn.com ihlanganise ulwazi oluthile mayelana nezinkampani ezisebenza e-Pakistan ukuze ziphendule imibuzo yakho mayelana nezindleko zesistimu sonozungezilanga, izinhlobo zayo, nokuthi ungonga malini.
Into yokuqala okudingeka uyinqume uhlobo lwesistimu yelanga oyifunayo, futhi kukhona ezintathu zazo: i-on-grid (eyaziwa nangokuthi i-on-grid), i-off-grid, ne-hybrid.
Isistimu yegridi ixhunywe enkampanini yamandla yedolobha lakho, futhi ungasebenzisa zombili izinketho: iamaphaneli elangakhiqiza amandla emini, futhi igridi yamandla inika amandla ebusuku noma lapho amabhethri ephansi.
Lolu hlelo lukuvumela ukuthi udayisele ugesi oweqile owuphehlayo enkampanini kagesi ngomshini obizwa nge-net meter, engonga imali eningi kusikweletu sakho.Ngakolunye uhlangothi, uzobe uncike ngokuphelele kugridi ebusuku, futhi njengoba uxhumeke kugridi ngisho nasemini, isimiso sakho sonozungezilanga sizocisha uma kwenzeka ukwehla komthwalo noma ukuhluleka kwamandla.
Amasistimu amaHybrid, nakuba exhunywe kugridi, afakwe amabhethri okugcina omunye ugesi oweqile okhiqizwa phakathi nosuku.Isebenza njengesivimbeli sokucisha ukulayisha nokuhluleka.Amabhethri ayabiza, nokho, futhi isikhathi sokulondoloza sincike ohlotsheni nekhwalithi oyikhethayo.
Njengoba igama liphakamisa, isistimu ye-off-grid ayixhunyanisiwe nanoma iyiphi inkampani yamandla futhi ikunikeza ukuzimela okuphelele.Kuhlanganisa amabhethri amakhulu futhi ngezinye izikhathi amajeneretha.Lokhu kubiza kakhulu kunezinye izinhlelo ezimbili.
Amandla esistimu yakho yelanga kufanele ancike enanini lamayunithi owadlayo inyanga ngayinye.Ngokwesilinganiso, uma usebenzisa amadivaysi angu-300-350, uzodinga uhlelo lwe-3 kW.Uma usebenzisa amayunithi angu-500-550, uzodinga isistimu engu-5 kW.Uma ugesi owusebenzisa nyanga zonke uphakathi kuka-1000 no-1100, uzodinga isistimu engu-10kW.
Izilinganiso ezisekelwe ezilinganisweni zamanani ezinikezwa izinkampani ezintathu zibeka izindleko zezinhlelo ze-3KW, 5KW kanye ne-10KW cishe ku-Rs 522,500, Rs 737,500 kanye ne-Rs 1.37 million ngokulandelanayo.
Nokho, kukhona isixwayiso: lawa manani asebenza kumasistimu angenawo amabhethri, okusho ukuthi lezi zilinganiso zihambisana nezinhlelo zegridi.
Kodwa-ke, uma ufuna ukuba nesistimu ye-hybrid noma uhlelo oluzimele, uzodinga amabhethri, angakhuphula kakhulu izindleko zesistimu yakho.
URuss Ahmed Khan, unjiniyela wokuklama nokuthengisa kwaMax Power eLahore, uthe kunezinhlobo ezimbili eziyinhloko zamabhethri - i-lithium-ion ne-tubular - futhi intengo incike kukhwalithi oyifunayo kanye nempilo yebhethri.
Owokuqala uyabiza - isibonelo, ibhethri ye-4kW pylon technology lithium-ion ibiza ama-Rs 350,000, kodwa iphila iminyaka eyi-10 kuya kweyi-12, kusho uKhan.Ungakwazi ukusebenzisa amalambu ambalwa, isiqandisi kanye ne-TV amahora angu-7-8 ngebhethri engu-4 kW.Kodwa-ke, uma ufuna ukusebenzisa i-air conditioner noma iphampu yamanzi, ibhethri izokhipha ngokushesha, wanezela.
Ngakolunye uhlangothi, ibhethri ye-tubular engu-210 amp ibiza ama-Rs 50,000.UKhan uthi isistimu engu-3 kW idinga amabili kulawa mabhethri ashubhu, okukunika amandla afinyelela emahoreni amabili wokusekela ngokulondoloza.Ungasebenzisa amalambu okukhanya ambalwa, izifeni, kanye nethani le-inverter AC kuyo.
Ngokolwazi olunikezwe i-Kaiynat Hitech Services (KHS), usonkontileka welanga ezinze e-Islamabad nase-Rawalpindi, amabhethri amashubhu amasistimu angu-3 kW no-5 kW abiza cishe ama-Rs 100,000 nama-Rs 200,160 ngokulandelana.
Ngokusho kuka-Mujtaba Raza, oyi-CEO ye-Solar Citizen, umphakeli wamandla elanga ozinze eKarachi, uhlelo lwe-10 kW olunamabhethri, ekuqaleni ayebiza ama-Rs 1.4-1.5 lakh, azokhuphukela ku-Rs 2-3 million.
Ngaphezu kwalokho, amabhethri adinga ukushintshwa njalo, okwengeza izindleko zizonke.Kodwa ikhona indlela yokweqa le nkokhelo.
Ngenxa yalezi zindleko, abasebenzisi abaningi bakhetha amasistimu egridi noma ahlanganisiwe abavumela ukuthi basebenzise i-net metering, indlela yokukhokha ekhokhisa ugesi abanikazi besistimu yelanga abengezayo kugridi.Ungathengisa noma yimaphi amandla engeziwe owakhiqizayo enkampanini yakho yamandla futhi unciphise isikweletu sakho ngamandla owadonsa kugridi ebusuku.
Enye imali encane uma kuqhathaniswa neyokulungisa.Amaphaneli elanga adinga ukuhlanzwa njalo, ngakho ungasebenzisa ama-rupee angama-2500 ngenyanga kulokhu.
Kodwa-ke, i-Solar Citizen's Raza ixwayise ngokuthi intengo yohlelo ingase iguquguquke uma kubhekwa ukuguquguquka kwezinga lokushintshisana ezinyangeni ezimbalwa ezedlule.
“Zonke izingxenye zesimiso sikanozungezilanga zithengwa kwamanye amazwe – ama-solar panel, ama-inverter ngisho nezintambo zethusi.Ngakho ingxenye ngayinye inenani ngamadola, hhayi ama-rupee.Amanani okushintshanisa ashintshashintsha kakhulu, ngakho-ke kunzima ukunikeza amaphakheji/isilinganiso.Lesi yisimo esibucayi semboni yelanga.”.
Amadokhumenti e-KHS aphinde abonise ukuthi amanani asebenza izinsuku ezimbili kuphela kusukela ngedethi inani elilinganiselwe elishicilelwe ngalo.
Lokhu kungaba yinkinga enkulu kulabo abacabanga ukufaka isistimu yelanga ngenxa yokutshala izimali ezinkulu.
URaza uthe inkampani yakhe ibisebenzisana namakhasimende ukwenza uhlelo lokuthi izikweletu zikagesi zehliswe zibe ziro.
Uma ucabanga ukuthi awunalo ibhethri, emini uzosebenzisa amandla elanga owakhiqizayo futhi udayisele inkampani yakho amandla elanga engeziwe.Kodwa-ke, ebusuku awukhiqizi amandla akho, kodwa sebenzisa ugesi ovela enkampanini yamandla.Ku-inthanethi, ungase ungazikhokhi izikweletu zakho zikagesi.
UKhan kaMax Power wenze isibonelo sekhasimende elisebenzisa amadivayisi angu-382 ngoJulayi walo nyaka futhi lakhokhisa u-Rs 11,500 ngenyanga.Inkampani iyifakele i-solar system engu-5 kW, ikhiqiza cishe amayunithi angama-500 ngenyanga kanye namayunithi ayizi-6 000 ngonyaka.UKhan uthe uma kubhekwa izindleko zikagesi eLahore ngoJulayi, ukubuyisela ekutshalweni kwezimali kuzothatha iminyaka emithathu.
Ulwazi oluhlinzekwe yi-KHS lubonisa ukuthi izikhathi zokukhokha zamasistimu angu-3kW, 5kW kanye no-10kW yiminyaka emi-3, engu-3.1 neminyaka engu-2.6 ngokulandelana.Inkampani ibale ukonga konyaka wama-Rs 204,097, ama-Rs 340,162 kanye nama-Rs 612,291 kulezi zinhlelo ezintathu.
Ngaphezu kwalokho, isimiso sonozungezilanga sinesikhathi sokuphila esilindelekile seminyaka engu-20 kuya kwengama-25, ngakho sizoqhubeka sikongela imali ngemva kokutshalwa kwezimali kwakho kokuqala.
Ohlelweni oluxhunywe nge-net-metered grid-connected, lapho ugesi ungekho kugridi, njengamahora okucishwa kukagesi noma lapho inkampani kagesi yehla, i-solar system iyacishwa ngokushesha, kusho u-Raz.
Amaphaneli elanga enzelwe imakethe yaseNtshonalanga ngakho-ke awakulungele ukucisha ugesi.Wachaza ukuthi uma ugesi ungekho kugridi, uhlelo luzosebenza ngaphansi kokucatshangwa ukuthi ukulungiswa kuyaqhubeka futhi luzovala ngokuzenzekelayo ngemizuzwana embalwa ukuvimbela noma yiziphi izigameko zokuphepha ngokusebenzisa umshini ku-inverter.
Ngisho nakwezinye izimo, ngesistimu eboshwe ngegridi, uzothembela ekuphakeleni kwenkampani yamandla ebusuku futhi ubhekane nokucishwa komthwalo kanye nanoma yikuphi ukwehluleka.
URaza wengeze ngokuthi uma uhlelo luhlanganisa namabhethri, azodinga ukushajwa njalo.
Amabhethri nawo adinga ukushintshwa njalo ngemva kweminyaka embalwa, angabiza amakhulu ezinkulungwane.
