Iimodyuli zeSolar photovoltaic, eyaziwa nangokuthi iipaneli zelanga, ziyinxalenye ebalulekileyo yeenkqubo zamandla elanga. Iimodyuli zenzelwe ukuguqula ukukhanya kwelanga kube ngumbane, okwenza kube ngumdlali ophambili kwicandelo lamandla ahlaziyekayo. Uyilo lwesekethe yeemodyuli zelanga ze-photovoltaic zibalulekile ekuqinisekiseni ukusebenza ngokufanelekileyo nokukhuselekileyo kwezi nkqubo. Kweli nqaku, siza kuphonononga kubunzima boyilo lwemodyuli yePV yelanga, sijonga izinto eziphambili kunye noqwalaselo olubandakanyekayo.
Ingundoqo yemodyuli ye-PV yelanga yi-photovoltaic (PV) iseli, ejongene nokuguqula ukukhanya kwelanga kumbane. Ezi seli ziqhele ukwenziwa ngezinto zesemiconductor ezifana nesilicon, kwaye xa zibekwe elangeni, zenza amandla ombane akhoyo ngokuthe ngqo (DC). Ukuhlanganisa la mandla ombane, uyilo lwesekethe yemodyuli ye-photovoltaic yelanga ibandakanya izinto ezininzi eziphambili.
Enye yezona zinto ziphambili kuyilo lwemodyuli ye-solar photovoltaic yi-bypass diode. I-Bypass diodes idityaniswe kwimodyuli ukunciphisa iziphumo zesithunzi okanye ukusilela kweeseli. Xa iseli yelanga inomthunzi okanye yonakaliswe, iba ngumqobo ekuhambeni kombane, ukunciphisa isiphumo esipheleleyo semodyuli. Iidiode ze-Bypass zibonelela ngenye indlela yangoku ukudlula iiseli ezinomthunzi okanye ezingaphumeleliyo, ziqinisekisa ukuba ukusebenza ngokubanzi kwemodyuli akuchaphazeleki kakhulu.
Ukongeza kwi-bypass diodes, uyilo lwesiphaluka seemodyuli ze-photovoltaic zelanga nazo zibandakanya iibhokisi ze-junction. Ibhokisi le-junction lisebenza njenge-interface phakathi kweemodyuli ze-PV kunye nenkqubo yombane yangaphandle. Igcina unxibelelwano lombane, iidiode kunye nezinye izinto ezifunekayo ukuze imodyuli isebenze ngokukhuselekileyo nangokufanelekileyo. Ibhokisi ye-junction ikwabonelela ngokhuseleko kwizinto zokusingqongileyo ezifana nokufuma kunye nothuli, ukukhusela amacandelo angaphakathi emodyuli.
Ukongezelela, uyilo lwesiphaluka seemodyuli ze-PV zelanga zibandakanya abalawuli bentlawulo, ngokukodwa kwiinkqubo ze-off-grid okanye ezizimeleyo. Izilawuli zokutshaja zilawula ukuhamba kombane ukusuka kwiipaneli zelanga ukuya kwipakethi yebhetri, ukuthintela ukutshaja kunye nokukhutshwa okunzulu kwebhetri. Oku kubalulekile ekwandiseni ubomi bebhetri kunye nokuqinisekisa uzinzo jikelele lwenkqubo yelanga.
Xa uyila iimodyuli zemodyuli ye-solar photovoltaic, i-voltage kunye nemilinganiselo yangoku yenkqubo yonke kufuneka ithathelwe ingqalelo. Ukucwangciswa kweemodyuli, nokuba kuchungechunge, ukuhambelana okanye ukudibanisa zombini, kuchaphazela i-voltage kunye namanqanaba akhoyo ngaphakathi kwesekethe. Ubungakanani besiphaluka esifanelekileyo kunye nokucwangciswa kubaluleke kakhulu ekwandiseni amandla ombane weemodyuli zelanga ze-photovoltaic ngelixa ugcina ukhuseleko kunye nokunyaniseka kwenkqubo.
Ukongezelela, uyilo lwesiphaluka seemodyuli zelanga ze-photovoltaic kufuneka zihambelane nemigangatho ekhuselekileyo yokhuseleko kunye nemimiselo. Oku kubandakanya ukumisa okufanelekileyo kunye nokukhuselwa kwe-overcurrent ukukhusela iingozi zombane. Ukuthobela le migangatho kuqinisekisa ukufakwa okukhuselekileyo kunye nokusebenza kweenkqubo zelanga, ukukhusela izixhobo kunye nabo bachaphazelekayo.
Kwiminyaka yakutshanje, ukuqhubela phambili kwetekhnoloji kuye kwavumela i-optimizers yamandla kunye ne-microinverters ukuba zidibaniswe kuyilo lwesekethe yeemodyuli ze-PV zelanga. Ezi zixhobo ziphucula ukusebenza kwemodyuli ngokwandisa amandla ombane wephaneli nganye yelanga kunye nokuguqula ngoku ngqo kwi-alternating current (AC) ukuze isetyenziswe kwiindawo zokuhlala okanye zorhwebo. Ngokudibanisa ezi zixhobo zombane eziphambili, ukusebenza kakuhle kunye nokuthembeka kweenkqubo zelanga ziphuculwe kakhulu.
Ukuqukumbela, uyilo lwesekethe yeemodyuli zePV zelanga zidlala indima ebalulekileyo ekusebenzeni nasekusebenzeni kwenkqubo yelanga. Ngokudibanisa amacandelo afana ne-bypass diodes, iibhokisi ze-junction, abalawuli bentlawulo kunye ne-electronics advanced, idizayini yesiphaluka iqinisekisa ukusebenza ngokufanelekileyo kunye nokukhuselekileyo kweemodyuli ze-solar photovoltaic. Njengoko imfuno yamandla avuselelweyo iqhubeka ikhula, ukubaluleka kweesekethe eziqinileyo kunye neziyilwe kakuhle kwiimodyuli ze-solar photovoltaic zibonakala zibonakala, zivula indlela yekamva lamandla azinzileyo.
Ukuba unomdla kwiimodyuli ze-solar photovoltaic, nceda uzive ukhululekile ukuqhagamshelana neRadiancekwisicatshulwa.
