Isisitemu sokubeka kwezinkundla ezihlukene ngokushintsha ngomnyaka | Ukushintsha kwemilinga kusuka ku-15–30° ukufaka umphela wokuphatha kwezinsola ngokuphelele kusuka ku-8–12% ngomnyaka ngaphandle kokubeka kwezinkundla ezihlukene
Izinhlelo zokufaka ezishintshashintshayo zishiya u-812% wokukhiqizwa kwamandla ngonyaka ongenzeka etafuleni hhayi ngenxa yezindleko zethuluzi lokulandelela, kodwa ngenxa yokuthi ukuthambekela okungu-10° okulungiselelwe ilanga lasehlobo kusebenza kabi ebusika, kuyilapho ukuthambekela okungu-25° ok Kubathuthukisi bamaphrojekthi abahlose ukuthola i-IRR ephezulu kusuka endaweni engaguquguquki, ukuthambekela okuguquguqukayo kuyindlela ephansi kakhulu yezindleko yokufinyelela kumkhiqizo ophakeme ngaphandle kobunzima bemishini yokulandelela.
Uhlelo lwe-Seasonal Adjustable-Tilt Ground Mount System luvumela amaqembu asensimini ukuba aguqule i-angle yokuthambekela ngezigaba ezingu-24 ngonyaka ngokuvamile kungakapheli imizuzu engu-30 nge-MW ngayinye esebenzisa amathuluzi ayisisekelo esandla. Uhlelo luhamba kusuka ku-15° kuya ku-30° ngezinyathelo ezihlukile, okwenza kube lula ukuhlela izinkathi zonyaka ezihlelwe amazinga okubukeka komhlaba:
Ehlobo (i-engeli elangeni eliphakeme): 1015° khulisa ukubanjwa kokukhanya okuqondile
Intwasahlobo/Inyanga (i-equinox): 2025° ibhalansi eqondile + ehlakazayo
Ubusika (i-engeli elincane elangeni): 2530° ukubamba ilanga lasebusika elincane, ukuthuthukisa ukuchitheka kweqhwa
Lokhu akuyi-ithrakha — akukho moto, akukho ikontrola, akukho isikhombisa sokuhamba esingafuneki ukubhala. Isikhombisa sokuguqula sisebenzisa isistimu yebhrekethi engekhiwe ngamapini nesikhombisa sezinkampani zokuguqula. Umsebenzisi omunye ongaphatha i-sokheti wensika ayaguqula amamodhuli angu-200 ngamuhla. Ukuphuluka kwezindlela zokufaka kungaba phakade ku-6–10% kwezindlela zokufaka, nokubuyiselwa kwemali ngamahora angu-12–18 ngokwenza imali engaphezulu ngokusebenzisa i-enerji.

Usuthelo: Indawo enobubanzi obuphezulu enokuhlukahluka okukhulu kwe-engeli yelanga (ama-22° ngesikhathi sehlobo vs 69° ebusika). Amanani entengo ye-PPA ayeba ne-premium ebusika engu-15%. Uhlelo lokulandelela oluphelele aluvunyelwe ngenxa yendawo enezintaba nezinkinga zeqhwa.
Ukuphatha: Uhlelo lokuthambekela olulungisekayo olunesixhumi esiqinisiwe esinezindawo ezi-4 (15°/20°/25°/30°). Insimbi engu-Q355B, enesembozo se-HDG. Ukwakheka kwe-module engu-2x12. Isisekelo se-screw phansi somhlabathi wezintaba onamadwala. Ukulungiswa kwesizini okwenziwa ngamalungu amabili omkhandlu ngosuku olulodwa ngesizini.
Ingeniso: Ukwanda komkhiqizo okulinganisiwe konyaka okungu-10.2% kunohlelo olufanayo oluhleliwe-10° endaweni efanayo. Umkhiqizo wasebusika uthuthuke ngo-24% uma uqhathaniswa no-10° oqondile, okuhlanganisa ngqo imali ekhokhwayo ye-PPA yasebusika. Ukubuyiselwa kwemali ye-premium ye-hardware enokuqondiswa kwe-tilt etholwe ezinyangeni ezingu-14. Lolu hlelo selusebenze iminyaka engu-4 kungekho zinkinga zokugcinwa kwemishini yokulungisa.
Q. Kuthatha isikhathi esingakanani ukuguqulwa kwesizini?
Cishe imizuzu engu-30 nge-MW ngayinye yeqembu labantu ababili elinamathuluzi angokwezifiso. Ukuze uthole indawo engu-10MW: cishe amahora ama-5 okusebenza, noma ekuseni owodwa wokusebenza, kane ngonyaka.
U. Isiphakathi esiyakwenzeka sisebenza ngokuthintana kwezinkinga zokulungisa?
Cha. Akukho moto, amabhiringi, amakhontrola noma izinyathelo ezingenakwenzeka okufanele zilungiswe noma zilishanyelwe. Isiphakathi sesikhumba esihlanganisa i-pins siyindlela yokuqondisa kuphela, futhi isikhumba senza isikhathi sokusebenza esingama-25 emva kwalokho kuzoba ngokufanayo nokwezinye iziqondiso. Ukubheka kwesikhathi esingama-12 isikhathi esifanayo kusobala ukuthi ipin iyasebenza kangakanani.
U. Kuphi umlingo wokuthintana ngezinkampani ezithintana ngokuphambuka?
Isiphakathi sesikhumba esiyakwenzeka sifaka umbhalo wokuthintana wezinkampani ngokuphambuka ngokugcwele ku-6–10%. Kusukela kumshini wokuphambuka wokugcwele wama-10MW, lokhu kuyabonakalisa umbhalo wokuthintana ngokuphambuka ngokugcwele ku-$0.005–0.008/Wdc. Uma kubhekwa ngokuthintana nokuthintana kwezinkampani ezithintana ngokuphambuka ngokugcwele ku-8–12% kusukela kuma-12–18 izinsuku zokubuyela.
