Iingcali zenzululwazi zaseSpain zavavanya iimodyuli ze-PV phantsi kweemeko ze-shading partial, zijolise ekuqondeni ngcono ukubunjwa kweendawo ezinobungozi bokusebenza.Uphononongo lubonisa umba onokuthi uchaphazele ngokukodwa iimodyuli ze-half-cell kunye ne-bifacial, ezinokubangela ukulahleka kwentsebenzo ngokukhawuleza kwaye akubandakanywa novavanyo lwangoku / imigangatho yokuqinisekisa.
Kuphononongo, iimodyuli zepaneli zelanga zenziwe ngomthunzi ngenjongo yokukhuthaza iindawo ezishushu.
Ukusika iiseli ze-silicon phakathi, kunye nokwenza ukuba zikwazi ukuvelisa umbane ukusuka ekukhanyeni kwelanga okubetha macala omabini, zimbini ezintsha eziye zazisa amathuba okunyusa isivuno samandla ngexabiso elincinci lemveliso elongezelelweyo.Ngenxa yoko, zombini ezi zikhule ngokukhawuleza kule minyaka imbalwa idlulileyo, kwaye ngoku zimele eyona nto iphambili kwiseli yelanga kunye nokuveliswa kwemodyuli.
Uphando olutsha, olwaluphakathi kwabaphumelele ibhaso lepowusta kwiInkomfa ye-EU PVSECebibanjelwe eLisbon kwinyanga ephelileyo, ibonise ukuba ukudityaniswa kwesiqingatha-ukusikwa kunye noyilo lweeseli ze-bifacial kunokufaka isandla kwimiba ye-hotspot kunye nentsebenzo, phantsi kweemeko ezithile.Kwaye imigangatho yovavanyo yangoku, ababhali bophononongo bayalumkisa, banokungaxhotyiswa ukubona iimodyuli ezisengozini kolu hlobo lokuthotywa.
Abaphandi, abakhokelwa ngumcebisi wobugcisa osekwe eSpain u-Enertis Applus, bagubungela iinxalenye zemodyuli yePV ukujonga indlela yokuziphatha kwayo phantsi komthunzi."Sinyanzelise isithunzi ukuba singene nzulu ekuziphatheni kweemodyuli ze-monofacial kunye ne-bifacial half-cell, sigxile ekubunjweni kwendawo eshushu kunye namaqondo obushushu afikelela kuwo," kuchaza uSergio Suárez, umphathi wezobugcisa behlabathi kwi-Enertis Applus.Okubangela umdla kukuba, sichonge iindawo ezishushu ezibonakala kwindawo echaseneyo ngokubhekisele kwiindawo eziqhelekileyo ezishushu ngaphandle kwezizathu ezicacileyo, ezifana nesithunzi okanye ukwaphuka.
Ukuthotywa ngokukhawuleza
Uphononongo lubonise ukuba idizayini ye-voltage yeemodyuli ze-half-cell inokubangela ukuba i-hotspots isasazeke ngaphaya kwendawo enomthunzi / eyonakeleyo."Iimodyuli zesiqingatha zeeseli zibonise imeko enomdla," waqhubeka uSuárez.“Xa kuvela i-hotspot, uyilo lwemodyuli oluhambelana nombane lutyhala ezinye iindawo ezingachaphazelekiyo ukuba ziphuhlise iindawo ezishushu nazo.Oku kuziphatha kunokubonisa ukuthotywa okunokukhawuleza kwiimodyuli ezinesiqingatha seeseli ngenxa yenkangeleko yezi ndawo zininzi.
Umphumo waphinda waboniswa ukuba unamandla ngakumbi kwiimodyuli ze-bifacial, ezifikelele kumaqondo okushisa ashushu ukuya kwi-10 C ephezulu kuneemodyuli zecala elinye kwisifundo.Iimodyuli zavavanywa ngexesha leentsuku ze-30 phantsi kweemeko eziphezulu ze-irradiance, kunye nesibhakabhaka esinamafu kunye nesicacileyo.Uphononongo kungekudala luza kupapashwa ngokupheleleyo, njengenxalenye yenkqubo ye-2023 EU PVSEC isiganeko.
Ngokutsho kwabaphandi, ezi ziphumo zityhila indlela eya kwilahleko yokusebenza engabandakanywanga kakuhle kwimigangatho yovavanyo lwemodyuli.
“Indawo eyodwa kwindawo esezantsi yemodyuli inokubangela iindawo ezininzi eziphezulu, ezinokuthi, ukuba azilungiswanga, zinokukhawulezisa ukuthotywa kwemodyuli ngokunyuka kwamaqondo obushushu,” utshilo uSuárez.Uphinde waqaphela ukuba oku kunokubeka ukubaluleka okongeziweyo kwimisebenzi yolondolozo efana nokucocwa kweemodyuli, kunye noyilo lwenkqubo kunye nokupholisa umoya.Kodwa ukubona ingxaki kwangethuba kungakhethwa koku, kwaye kufuna amanyathelo amatsha kuvavanyo kunye noqinisekiso lomgangatho kwinqanaba lokuvelisa.
"Izinto esizifumeneyo zibonakalisa imfuno kunye nethuba lokuphonononga kwakhona kunye nokuhlaziya imigangatho ye-half-cell kunye nobuchwepheshe be-bifacial," utshilo uSuárez."Kubalulekile ukwenza into kwi-thermography, ukwazisa iipateni ezithile zobushushu kwisiqingatha seeseli kunye nokulungelelanisa ukunyanzeliswa kweemitha ezishushu kwiiMeko zoVavanyo oluMgangatho (STC) kwiimodyuli ze-bifacial."
