Ukukhangela izisombululo ezizinzileyo zamandla, itekhnoloji ye-Photovoltaic (PV) sele ilitye lesiseko sombane wale mihla. Njengoko imfuno yamandla ahlaziyekayo iyaqhubeka nokukhula, izityalo zamandla amakhulu ziyaguquka zisiba jikeleleIinkqubo zokulandela umkhondo wefotovoltaic. Ezi nkqubo azisebenzi nje ukubanjwa kwelanga, kodwa kukuphucula ukufezekiswa nokusebenza ngendleko zemveliso yamandla elanga.
Entliziyweni yenkqubo yokulandela umkhondo wefoto kukukwazi ukulandelela ukukhanya kwelanga ngexesha lokwenyani. Ngokungafaniyo ziiphaneli zelanga zaseSolar, ezinokuthi zifake ukukhanya kwelanga kwi-angle ethile, iinkqubo zokulandela umkhondo zilungisa ukuqhelaniswa kweephaneli zelanga imini yonke. Olu hlengahlengiso lukrelekrele luvumela iipaneli ukuba zilandele indlela yelanga, ukuxhasa ukubonakaliswa kwelanga kwaye ke ngoko imveliso yamandla. Ngokusebenzisa itekhnoloji yokuzilalela, ezi nkqubo zinokuziqhelanisa nendawo yokutshintsha kwelanga, ekuqinisekiseni ukuba iiphaneli zesola zihlala zihambelana nokusebenza kakuhle.
Enye yezibonelelo eziphambili zeenkqubo zokulandela umkhondo wefoto kukukwazi kwabo ukunciphisa ilahleko yesithunzi. Kwizityalo ezikhulu zamandla, nkqu nezithintelo ezincinci zinokubangela ilahleko ebalulekileyo yamandla. Ngokulungelelanisa i-angle yeephaneli zelanga, iinkqubo zokulandela umkhondo zinciphisa ifuthe lemithunzi etyhidweyo yizakhiwo ezikufuphi okanye ezinye iipaneli. Obo banokukwazi kubaluleke kakhulu kwiifama ezinkulu zelanga apho ubume bunokubangela khona iipateni ezinzima. Ngokulawula kakuhle le mithunzi, iinkqubo zokulandela umkhondo zinokuphucula amandla okuvelisa amandla, ukuvumela izityalo zamandla ukukhupha amandla amaninzi ukusuka kwinani elifanayo lokukhanya kwelanga.
Ukwengeza,Iinkqubo zokulandela umkhondo wefotovoltaiczenzelwe ukunciphisa iziphumo zokutshintsha kweemeko zemozulu. Iiphaneli zesolar zemveli zeSolar zinokubandezeleka ekunciphiseni ngempumelelo kwifu okanye kwiintsuku zemvula. Nangona kunjalo, iinkqubo zokulandelela umkhondo zinokulungelelanisa isikhundla sabo ukufaka esona sixa siphezulu sokukhanya kwelanga esikhoyo, nangaphantsi kweemeko zemozulu ezifanelekileyo. Olu tshintsho alupheleli nje ukuvelisa amandla, kodwa ikwabonelela ngokhuseleko olungcono kuyo yonke inkqubo yefotoVoltaic. Ngokwenza i-angle yephaneli, ezi nkqubo zinokunciphisa ukunxila kunye nekratshi ezibangelwe ziimeko zemozulu ezibi, ngaloo ndlela zandisa ubomi bofakelo lwelanga.
Izibonelelo zoqoqosho zokumiliselwa kweenkqubo zokulandela umkhondo wefoto kwizityalo ezinkulu zamandla zibalulekile. Ngokwandisa iziphumo zamandla kunye nokucutha ilahleko yesithunzi, ezi nkqubo zinegalelo kwiindleko eziphantsi zokusebenza. Ukwanda kokusebenza kakuhle kwimbuyekezo ephezulu kutyalo-mali, ukwenza amandla elanga okhuphiswano ngakumbi kwimithombo yamandla yesintu. Njengoko izityalo zamandla zizama ukuhlangabezana neemfuno zokukhulisa amandla ngelixa kuncitshiswa iindleko, ukudityaniswa kwetekhnoloji yokulandela umkhondo kuba sisibonelelo esicwangcisiweyo.
Ukongeza, ukukhululeka kweenkqubo zokulandela umkhondo ze-PV kuyabavumela ukuba zisetyenziswe kwiindlela ezahlukeneyo zeseto, ukusuka kwiifama ezizezimali ezizezimali ezifakelweyo kwintengiso. Oku kuqala kukuqinisekisa ukuba uluhlu olubanzi lwezityalo zamandla lunokuxhamla kwitekhnoloji, nokuba ubungakanani okanye indawo. Njengoko ishishini lelanga liyaqhubeka ukuvela, ukusetyenziswa kweenkqubo zokulandela umkhondo kunokwenzeka ukuba kubekho ngokubanzi, ukuqhuba okuqhubekayo ekusebenzeni kwaMandla kunye nokuncitshiswa kweendleko.
Isishwankathelo,Iinkqubo zokulandela umkhondo wefotovoltaicimele i-theap ebalulekileyo ngaphambili kwitekhnoloji yamandla elanga. Ngokwenza ukuba ukwenze umkhondo wexeshana wexesha, ukufezekisa ubuchule bokuziqhelanisa nengqondo kunye nolawulo lwesithunzi olusebenzayo, ezi nkqubo zinyusa ukusebenza kakuhle kwezityalo zamandla xa kuncitshiswa iindleko zezityalo ezikhulu. Njengoko umhlaba usiya kwixesha elizayo lamandla ngakumbi, ukudityaniswa kwetekhnoloji yokulandela umkhondo kuya kudlala indima ebalulekileyo ekukhuliseni amandla elanga kunye nokuqinisekisa ukuba ihlala ingumthombo wamandla omntu ukuza kuthi ga ngoku.
