Lub hnub ci hluav taws xob tsim hluav taws xob yog lub zog huv si uas siv cov khoom siv hnub ci zog rau kev hloov hluav taws xob thiab khoom siv.
Nws lub hauv paus ntsiab lus tseem ceeb yog cov nyhuv photovoltaic, uas ncaj qha hloov lub hnub ci zog rau hauv lub zog hluav taws xob, muab qhov zoo xws li kev phooj ywg ib puag ncig, rov ua dua tshiab, thiab kev ua haujlwm ruaj khov. Tam sim no, tus nqi ntau rau lub hnub ci hluav taws xob tsim hluav taws xob yog dav. Cov chaw nyob me me feem ntau yog li ntawm 10,000 txog 50,000 yuan, thaum lub lag luam loj lossis kev lag luam muaj peev xwm ncav cuag ntau pua txhiab lossis ntau lab yuan. Tus nqi tshwj xeeb yog cuam tshuam los ntawm qhov system muaj peev xwm, cov khoom siv zoo, thiab kev teeb tsa tsis yooj yim.
Lub hnub ci hluav taws xob tsim hluav taws xob feem ntau muaj cov khoom siv hluav taws xob photovoltaic, lub inverter, lub tshuab hluav taws xob, thiab lub zog cia khoom (yeem). Photovoltaic modules yog tsim los ntawm ntau lub hnub ci vaj huam sib luag txuas nrog hauv series lossis parallel, tsim hluav taws xob ncaj qha (DC) los ntawm cov nyhuv photovoltaic ntawm cov khoom siv semiconductor. Lub inverter hloov DC rau alternating tam sim no (AC) kom tau raws li cov qauv kev sib txuas ntawm kab sib chaws rau cov khoom siv hauv tsev lossis daim phiaj hluav taws xob. Tus maub los tswj kev ua haujlwm ntawm lub cev, tiv thaiv kev them nyiaj ntau dhau lossis dhau - tso tawm, thiab txuas ntxiv roj teeb lub neej. Lub zog cia khoom siv (xws li roj teeb lithium) khaws lub zog ntau dhau rau siv thaum hmo ntuj lossis hnub huab cua.
