Ukukhuthaza utshintsho lwezakhiwo zamandla kunye nokulwa notshintsho lwemozulu, ishishini le-photovoltaic—icandelo lamandla avuselelekayo—libalulekile. Ishishini le-photovoltaic (PV) okwangoku liphantsi kwesigaba sophuhliso olungazange lubonwe ngaphambili ngenxa yemeko yetekhnoloji etshintsha rhoqo kunye nokunyuka kwemfuno yabathengi.
Phakathi kwinkulungwane yama-20, xa iiseli zelanga zaziveliswa ngempumelelo okokuqala, kwadalwa ishishini le-PV. Kwiminyaka emininzi edlulileyo, kwenziwe inkqubela phambili enkulu kwicandelo le-photovoltaic (PV), nto leyo ekhokelele ekuphuhlisweni kweemveliso ezininzi ezintsha, kuquka iiseli zelanga ezithambileyo, i-polycrystalline silicon, kunye neeseli zelanga ze-monocrystalline silicon zokuqala. Ngokwahlukileyo koko, ixabiso lokuveliswa kwamandla e-PV liye lehla kancinci ngenxa yokuphuculwa kokusebenza kakuhle kwemodyuli ye-PV, okuvumela ukuba ikwazi ukumelana neminye imithombo yamandla avuselelekayo.
Nangona ishishini le-PV liphumelela, alinazo iingxaki kunye nemiqobo. Ukufumaneka okulinganiselweyo komhlaba onokulinywa yenye yezinto ezinjalo. Ingxaki enkulu kwimimandla enemithombo yomhlaba embalwa yindawo eninzi efunwa zizityalo ezinkulu ze-PV. Ngenxa yoku, iindlela zokusebenzisa ezinye ii-PV kufuneka ziphandwe ukuze kusetyenziswe umhlaba okhoyo kakhulu.
Inkqubo yokuvelisa umbane we-PV esasazwayo yindlela entsha yokusebenzisa ubuchwepheshe be-PV. Iimodyuli ze-solar photovoltaic (PV) ezifakwe kwiindawo ezahlukeneyo, kuquka iindonga kunye nophahla, zivelisa umbane ngqo ukusuka elangeni kwaye ziwusasaze kwizakhiwo ngenkqubo yokuvelisa umbane we-PV esasazwayo. Le modeli inika uluhlu lweenzuzo, ezizezi zilandelayo: ekuqaleni, yenza ngcono ukusetyenziswa kommandla wesakhiwo ngelixa ngaxeshanye inciphisa ukusetyenziswa kwezixhobo zomhlaba; okwesibini, iphucula ukusebenza kakuhle kokusetyenziswa kwamandla ngelixa inciphisa ilahleko yokudluliselwa kwegridi; kwaye okwesithathu, ivelisa umbane ococekileyo, ohlaziyekayo ngelixa inciphisa ukuxhomekeka kumafutha aqhelekileyo efosili.
Iinkqubo zokuvelisa umbane we-PV zomzimba odadayo ziluhlobo olongezelelweyo lwesicelo se-PV, ukongeza kwiinkqubo zokuvelisa umbane we-PV ezisasazwayo. Inkqubo yokuvelisa umbane we-PV yomzimba odadayo isekwa ngokuncamathisela iimodyuli ze-photovoltaic kumphezulu wamanzi kusetyenziswa iqonga lokudada. Iingenelo zemodeli zezi zilandelayo: okokuqala, yenza ngcono ukusetyenziswa kommandla wamanzi endaweni yokufuna izixhobo zomhlaba; okwesibini, iphucula ukuveliswa kombane ngokuphucula ukusebenza kakuhle kweemodyuli ze-photovoltaic ngenxa yesiphumo sokupholisa samanzi; kwaye okwesithathu, inciphisa ukuxhomekeka kumafutha efosili aqhelekileyo ngelixa ibonelela ngombane ococekileyo nohlaziyekayo.
Ukongeza kwezinye iimodeli ezimbalwa eziphawulekayo zesicelo se-PV. Umzekelo woku yimodeli yezolimo ye-PV, esebenzisa iimodyuli ze-PV ukuvelisa umbane kunye nokulima ukutya ngaxeshanye. Ngaphezu koko, ukuhlanganiswa kwenkqubo yokugcina amandla ye-PV kunye netekhnoloji yokuvelisa umbane ye-PV kunokubonelela ngombane oqhubekayo xa kukho ukucima kombane welanga. Iindlela ezintsha kunye neembono zokwanda kwexesha elide kweshishini le-PV ziye zavela ukusukela oko kwaqaliswa ezi ntlobo zezicelo zintsha.
Inkxaso evela kurhulumente kunye nesikhokelo malunga nomgaqo-nkqubo zibalulekile ekuphuhlisweni kweendlela ezintsha zokusetyenziswa kwe-PV. Urhulumente unokuxhasa nokukhuthaza ukwandiswa kweshishini le-PV ngokusebenzisa imigaqo-nkqubo nemigaqo efanelekileyo, ukubonelela ngenkxaso-mali kunye neenzuzo zerhafu, kunye nokwamkelwa kophuhliso olongezelelweyo lwetekhnoloji. Okwangoku, inkxaso karhulumente yophando lwesayensi kunye noyilo lwetekhnoloji inokunceda ukuqhubela phambili nokwandiswa kwetekhnoloji ye-photovoltaic.
Intsebenziswano kunye nentsebenziswano yamazwe ngamazwe zibalulekile ekwandiseni imboni ye-PV. Kubalulekile ukuba amazwe asebenzisane, abelane ngezixhobo nolwazi, kwaye akhuthaze ukwandiswa okutsha kwemboni ye-PV. Kufuneka sijongane nemingeni yamandla kunye nokusingqongileyo esijongene nayo njengoluntu lwehlabathi ukuze sifumane uphuhliso oluzinzileyo.
