Ubuso obubiniI-photovoltaics okwangoku iyindlela eyaziwayo kumandla elanga.Ngelixa iiphaneli ezinamacala aphindwe kabini zisabiza kakhulu kuneepaneli zemveli ezicalanye, zonyusa kakhulu imveliso yamandla apho kufanelekileyo.Oku kuthetha ukuhlawula ngokukhawuleza kunye neendleko eziphantsi zamandla (LCOE) kwiiprojekthi zelanga.Enyanisweni, uphando olutshanje lubonise ukuba ukufakwa kwe-1T ye-bifacial (okt, i-bifacial arrays yelanga efakwe kwi-tracker ye-axis enye) inokunyusa imveliso yamandla ngama-35% kwaye ifikelele kwixabiso eliphantsi lombane (LCOE) kwihlabathi kubantu abaninzi ( I-93.1% yendawo yomhlaba).La manani anokuthi aphucuke njengoko iindleko zemveliso ziqhubeka nokuhla zisiya ezantsi kwaye ukusebenza okutsha kobugcisa kufunyenwe.
      Iimodyuli zelanga ze-Bifacial zibonelela ngeenzuzo ezininzi kwiipaneli zelanga eziqhelekileyo ngenxa yokuba umbane unokuveliswa kumacala omabini emodyuli ye-bifacial, ngoko ke ukwandisa amandla apheleleyo aveliswa yinkqubo (ukuya kwi-50% kwezinye iimeko).Ezinye iingcali ziqikelela ukuba imarike ye-bifacial iya kukhula ngokuphindwe kalishumi kwiminyaka emine ezayo.Inqaku lanamhlanje liza kuphonononga ukuba isebenza njani i-PV ye-bifacial, izibonelelo zetekhnoloji, ezinye zemida, kwaye xa kufuneka (kwaye akufanele) uzithathele ingqalelo kwisixokelelwano sakho selanga.
Ukubeka nje, i-bifacial solar PV yimodyuli yelanga ethatha ukukhanya kumacala omabini ephaneli.Ngelixa iphaneli yemveli "yecala elinye" inesigqubuthelo esiqinileyo, se-opaque kwelinye icala, imodyuli ye-bifacial iveza zombini ngaphambili nangasemva kweseli yelanga.
      Phantsi kweemeko ezifanelekileyo, iipaneli zelanga ze-bifacial ziyakwazi ukuvelisa amandla amaninzi ngakumbi kuneepaneli zelanga eziqhelekileyo.Oku kungenxa yokuba ukongeza kwilanga elithe ngqo kumphezulu wemodyuli, bayazuza kukukhanya okubonakalisiweyo, ukukhanya okusasazeka kunye ne-albedo irradiance.
      Ngoku siphonononge ezinye zezibonelelo zeepaneli zelanga ezimbini, kubalulekile ukuqonda ukuba kutheni zingenzi ngqiqo kuzo zonke iiprojekthi.Ngenxa yeendleko zabo ezonyukayo ngaphezulu kweephaneli zelanga ezinecala elinye, kuya kufuneka uqiniseke ukuba inkqubo yakho inokuthatha ithuba loncedo lokuseta ipaneli ye-bifacial.Umzekelo, enye yeendlela ezingabizi kakhulu kunye nezona zilula zokwakha isixokelelwano selanga namhlanje kukusebenzisa ithuba lophahla olukhoyo olujonge emazantsi kwaye ufakele iiphaneli ezininzi ezihlaziyiweyo kangangoko kunokwenzeka.Inkqubo efana nale inciphisa iindleko zokubeka kunye nokufaka kwaye ikunceda ukuba uqalise ukuvelisa umbane ngaphandle kweteyiphu ebomvu okanye imvume.Kule meko, iimodyuli ezinamacala amabini zisenokungafanelanga.Ngenxa yokuba iimodyuli zifakwe ngokusondeleyo eluphahleni, akukho ndawo eyaneleyo yokuba ukukhanya kudlule ngasemva kweepaneli.Nokuba unophahla olunemibala eqaqambileyo, ukuba ukhwelisa uthotho lweepaneli zelanga ezisondeleleneyo, akukabikho ndawo yokubonisa.Ngaphambi kokuba uqale iprojekthi yakho, kufuneka uqonde ukuba loluphi uhlobo lokuseta kunye noyilo lwenkqubo olulungele ipropathi yakho eyodwa, indawo, kunye neemfuno zakho okanye zeshishini lakho.Kwiimeko ezininzi, oku kunokubandakanya iiphaneli zelanga ezinamacala amabini, kodwa kukho iimeko apho iindleko ezongezelelweyo zingenangqiqo.
      Ngokucacileyo, njengakuyo yonke iprojekthi yelanga, uyilo lwenkqubo luya kuxhomekeka kwizinto ezininzi ezahlukeneyo.Iiphaneli zelanga ezinecala elinye zisenayo indawo kwaye aziyi ndawo ixesha elide.Oko kwathiwa, abaninzi bakholelwa ukuba sikwixesha elitsha le-PV apho iimodyuli eziphezulu eziphezulu zilawula ubuchwephesha obuphezulu kunye ne-bifacial ngumzekelo oyintloko wendlela isivuno samandla esiphezulu esinokufezekiswa ngayo ngokusebenzisa izinto eziphezulu."Iimodyuli zeBifacial likamva loshishino," utshilo uHongbin Fang, umlawuli wezobugcisa weLongi Leye."Izuza njengelifa zonke izibonelelo zeemodyuli ze-monocrystalline PERC: ukuxinana kwamandla aphezulu okonga okubalulekileyo kwe-BOS, isivuno samandla aphezulu, ukusebenza okungcono kokukhanya okuphantsi kunye ne-coefficient ephantsi yobushushu.Ukongeza, iimodyuli ze-PERC ze-bifacial nazo zivuna amandla ukusuka kwicala elingasemva, zibonisa isivuno esiphezulu samandla.Sikholelwa ukuba iimodyuli ze-PERC ze-bifacial zezona ndlela zokufikelela kwi-LCOE ephantsi.Ukongeza, kukho ezininzi itekhnoloji yelanga ye-PV enezivuno eziphezulu kuneepaneli ze-bifacial, kodwa iindleko zabo zisaphezulu kangangokuba azinangqiqo kwiiprojekthi ezininzi.Owona mzekelo ucacileyo kukufakwa kwelanga kunye ne-double-axis tracker.Iitraki ze-Dual-axis zivumela iiphaneli zelanga ezifakelweyo ukuba zihambe zinyuka zisihla, ekhohlo nasekunene (njengoko negama lisitsho) ukulandelela indlela yelanga imini yonke.Nangona kunjalo, nangona imveliso yamandla iphezulu efunyenwe kwi-tracker, ixabiso lisephezulu kakhulu ukuthethelela ukunyuka kwemveliso.Nangona kukho izinto ezininzi ezintsha eziza kwenziwa kwintsimi yelanga, iipaneli zelanga ze-bifacial zibonakala ziyisinyathelo esilandelayo, njengoko zinamandla okusebenza kwamandla aphezulu ngokumalunga nokufikeleleka komda weepaneli eziqhelekileyo.
