Ngophuhliso oluqhubekayo lweteknoloji ye-photovoltaic, izibane zesitalato zelanga ziba zixhaphake ngakumbi ebomini bethu. izibane zasesitalatweni zelanga zizibane zangaphandle ezisebenzisa ukukhanya kwelanga njengomthombo wamandla. Akukho mfuneko yokumba imibhobho kunye nokubeka iintambo, okonga iindleko zombane. Iiphaneli zelanga zifunxa amandla elanga emini, kwaye amandla okukhanya aguqulwa abe ngamandla ombane, athi ke agcinwe yibhetri egcwalisekayo. Ebusuku, ibhetri inika amandla ombane kumthombo wokukhanya ukukhanyisa izixeko kunye neendawo zasemaphandleni. Ngoko njaniizibane zesitalato zelanga ukuguqula ukukhanya kwelanga kumandla ombane ngokusebenzisa iiphaneli zelanga ukuze zigcinwe? Kule nkqubo, luluphi ulungelelwaniso olubandakanyekayo? Makhe sijonge kuyo ngokweenkcukacha.
1. Umgaqo osebenzayo weepaneli zelanga
izibane zesitalato zelanga zinokuvelisa umbane ikakhulu ngokusebenzisa isiphumo se-photovoltaic sezinto ze-semiconductor, ezinokuguqula ukukhanya kwelanga kumandla ombane. Iiphaneli zelanga zenziwe ngee-semiconductors ezimbini ezahlukeneyo, uhlobo lwe-N kunye nohlobo lwe-P. Ukudibanisa phakathi kwabo kubizwa ngokuba yi-PN junction. Xa iphaneli yelanga ifumana ukukhanya, kulo mdibaniso we-PN, ii-electron zikhutshwa ngenxa yamandla okukhanya, kwaye izibini ezihambelanayo ze-electron-hole zenziwa. Imingxuma ye-N-type semiconductor iya kuhamba kwi-P-type, kwaye i-electron kwindawo yohlobo lwe-P iyakulibala ukuhamba kwendawo yohlobo lwe-N, yenze umsinga ukusuka kummandla we-N ukuya kwi-P-uhlobo. ummandla. Xa isekethe yangaphandle iqhagamshelwe, kuya kubakho uMbane ophumayo.
2. ulungiselelo lombane wesibane sesitrato sombane
izibane zelanga ezitalatweni ikakhulu zenziwe ngeepaneli zelanga, izilawuli, iibhetri kunye nezinye izixhobo. Ke ezi zincedisi zidlala yiphi indima kwinkqubo yokukhanyisa ezitalatweni?
Iphaneli yelanga
Iphaneli yelanga iyona nxalenye ephambili yesibane sesitalato, kwaye umsebenzi wayo kukuguqula amandla okukhanya kumandla ombane, kwaye emva koko uyithumele kwibhetri yokugcina indawo yokugcina, ekulungele ukukhanya ebusuku okanye ukukhuthaza umsebenzi womthwalo.
Ibhetri
Iibhetri ezineasidi yelothe zazidla ngokusetyenziswa ngaphambili, kodwa ngoku ngokuthe ngcembe zithatyathelw’ indawo ziibhetri ze-lithium iron phosphate. Ibhetri yokugcina idinga ukugcina amandla elanga athathwe ngamapaneli elanga emini kangangoko kunokwenzeka kwisiseko sokwanelisa ukukhanya ebusuku. Ngelo xesha, kufuneka ikwazi ukugcina amandla ombane anokuthi ahlangabezane neemfuno zokukhanyisa iintsuku eziqhubekayo zemvula ebusuku. Umthamo webhetri uncinci kakhulu ukuhlangabezana neemfuno zokukhanya ebusuku, umthamo ukhulu kakhulu, ibhetri iya kuhlala ikwimeko yokulahlekelwa kwamandla, ichaphazela ubomi benkonzo, kwaye ibangele inkunkuma. Ngoko ke, xa siqulunqa izibane zesitalato zelanga, kufuneka sizilungiselele ngokweemeko zangempela zokusetyenziswa kunye nemozulu yendawo ukwenzela ukuhlangabezana neemfuno zokukhanyisa zabasebenzisi.
Umlawuli
Igama elipheleleyo liyintlawulo yelanga kunye nomlawuli wokukhupha, kwaye sinokuqonda umsebenzi walo ukusuka kweli gama. Umlawuli usetyenziselwa ukulawula imeko yokusebenza kwayo yonkeinkqubo yokukhanya kwesitrato yelanga . Ikwadlala indima ekukhuseleni ibhetri kwi-overcharging and overdischarging. Ukusebenza kwayo kuchaphazela ngqo ubomi benkonzo yezibane zesitalato zelanga, ngakumbi ubomi benkonzo yeebhetri. Xa ukukhanya kwelanga kubetha i-solar panel, i-solar panel iya kuhlawulisa ibhetri. Ngaxeshanye, umlawuli uya kuzibona ngokuzenzekelayo i-voltage yokutshaja, kunye ne-voltage ephumayo kwisibane selanga, ukwenzela ukuba ukukhanya kwesitalato selanga kuya kukhanya.
Ukubeka nje, izibane zesitalato zelanga zifunxa amandla elanga ngeepaneli zelanga, ziwagcine ebhetrini, emva koko umlawuli akhuphe imiyalelo kwibhetri ukubonelela umbane kwizibane zesitrato. izibane zelanga ezitalatweni ziyawonga umbane, zinobuhlobo nokusingqongileyo, zikhuselekile kwaye ziluncedo, kwaye zinokuzisa inzuzo yexesha elide. Ukuba uneminye imibuzo malunga nezibane zesitalato zelanga, zive ukhululekile ukuqhagamshelana nathi.
Njengoko kuboniswe kumfanekiso, i-Zenith Lighting ngumvelisi oqeqeshiweyo wazo zonke iintlobo zezibane zesitalato, ukuba unemibuzo okanye iprojekthi, nceda unganqikazi ukudibanisa nathi.
