Amandla elanga asephenduke enye indlela enkulu esikhundleni samafutha emvelo, enikeza umthombo wamandla ozinzile futhi onobungani nemvelo. Enhliziyweni yobuchwepheshe bephaneli yelanga kukhona i-solar backplane, eyingxenye ebalulekile ekusebenzeni kwayo yonke kanye nesikhathi sokuphila kwephaneli yelanga. Kodwa-ke, ukuqonda ukwehluleka kwe-solar backplane kubalulekile ekuqinisekiseni ukuthembeka nokusebenza kahle kwezinhlelo zamandla elanga.
Iishidi langemuva lelangaungqimba olungaphandle kakhulu lwephaneli yelanga, ngokuvamile olwenziwe ngezinto ze-polymer ezifana ne-polyvinyl fluoride (PVF) noma i-polyvinyl chloride (PVC). Umsebenzi walo oyinhloko ukuvikela izingxenye zangaphakathi zephaneli yelanga (kufaka phakathi amaseli e-photovoltaic) ezicini zemvelo ezifana nomswakama, imisebe ye-UV kanye nokucindezeleka kwemishini. Iphepha elingemuva eliklanywe kahle alikwazi nje ukuthuthukisa ukuqina kwephaneli yelanga, kodwa futhi lithuthukisa ukusebenza kahle kwayo iyonke.
Naphezu kokubaluleka kwayo, i-solar backsheet nayo ingahluleka, okuthinta ukusebenza kwephaneli yakho yelanga. Esinye sezimbangela ezivame kakhulu zokwehluleka kwe-backsheet ukuwohloka kwemvelo. Amaphaneli elanga avame ukuchayeka ezimweni zezulu ezinzima, okuhlanganisa amazinga okushisa aphezulu, umswakama, kanye nemisebe ye-UV. Ngokuhamba kwesikhathi, lezi zici zingabangela ukuthi izinto ze-backsheet ziwohloke, okuholela ekuqhekekeni, ekuqhekekeni, noma ekuqhekekeni. Ukwehluleka okunjalo kungadalula izingxenye zangaphakathi zephaneli yelanga emswakama, okuholela ekugqwaleni nasekusebenzeni kahle okuncishisiwe.
Esinye isici esibalulekile esibangela ukwehluleka kwe-solar backsheet ukukhubazeka kokukhiqiza. Kwezinye izimo, ikhwalithi yezinto ezisetshenziswa ku-backsheet ingase ingahlangabezani nezindinganiso zemboni, okuholela ekuhlulekeni kwangaphambi kwesikhathi. Ukunamathelana okwanele phakathi kwe-backsheet namaseli elanga nakho kungaholela ekuhlukaniseni, okungathinta kakhulu ukusebenza kwephaneli. Abakhiqizi kumele balandele izinyathelo eziqinile zokulawula ikhwalithi ukuqinisekisa ukuthi ama-backsheet asetshenziswa kumaphaneli elanga aqinile futhi athembekile.
Ngaphezu kwalokho, ukufakwa okungafanele kungaholela ekungasebenzi kahle kweshidi langemuva. Uma amaphaneli elanga engafakwanga kahle, angase abe ngaphansi kokucindezeleka okukhulu kwemishini, okungabangela ukuthi ishidi langemuva liqhekeke noma lihlukane nephaneli. Abafaki kumele balandele imikhuba emihle kanye neziqondiso ukuqinisekisa ukuthi amaphaneli elanga afakwe ngokuphephile futhi angamelana nokucindezeleka kwemvelo.
Ukuze kuncishiswe ingozi yokwehluleka kwe-solar backplane, ukulungiswa nokuhlolwa njalo kubalulekile. Abanikazi bamaphaneli elanga kufanele benze ukuhlolwa njalo ukuze bathole noma yiziphi izimpawu zokuguguleka noma ukulimala kwe-backplane. Ukutholwa kwezinkinga kusenesikhathi kungavimbela izinkinga ezinkulu kamuva, kuqinisekiswe ukuthi uhlelo lwelanga luyaqhubeka nokusebenza kahle.
Ngaphezu kwalokho, intuthuko kwezobuchwepheshe ivula indlela yama-backsheet elanga aqinile futhi athembekile. Abacwaningi bahlola izinto ezintsha kanye nezingubo ezingathuthukisa ukumelana kwe-backsheet nezinto zemvelo. Kuphinde kwakhiwe izinto ezintsha ezinqubweni zokukhiqiza ukuze kuthuthukiswe ukunamathela kwe-backsheet kanye nekhwalithi iyonke.
Ngamafuphi, ukuqondaishidi langemuva lelangaukwehluleka kubalulekile ekugcineni ukusebenza kahle kanye nobude besikhathi samaphaneli elanga. Ngokuqonda izici ezibangela ukuwohloka kokusebenza kweshidi langemuva, okuhlanganisa izimo zemvelo, amaphutha okukhiqiza, kanye nemikhuba yokufaka, ababambiqhaza bangathatha izinyathelo zokuvimbela ukwehluleka. Njengoba imboni yelanga iqhubeka nokukhula, ucwaningo oluqhubekayo kanye nentuthuko kuzodlala indima ebalulekile ekuthuthukiseni ukuqina kwamashidi angemuva elanga, ekugcineni kuvumele izinhlelo zelanga ezithembeke kakhulu nezisebenza kahle.
