Lub tsev photovoltaic tshuab hluav taws xob tsim hluav taws xob qhov project yog lav los ntawm lub tuam txhab daim phiaj rau daim phiaj sib txuas noj. Yog li yuav ua li cas thiaj li tsim tau lub tsev photovoltaic systems project nrog atsev power bank? Muaj pes tsawg xyoo tus nqi tuaj yeem rov qab tau? Thiab qhov xwm txheej siv thoob ntiaj teb tam sim no yog dab tsi? Hauv tsab xov xwm no, peb yuav tham txog qhov ua tau ntawm kev tsom xam ntawm qhov tam sim no photovoltaic solar system teeb tsa lub zog hauv tsev los ntawm peb kis. Hauv qee qhov chaw tsim kho, tus nqi ntawm kev siv hluav taws xob yog qhov siab, thiab tag nrho cov phiaj xwm tsis ruaj khov thiab txhim khu kev qha. Yog li ntawd, txo cov nqi hluav taws xob tag nrho yog qhov tseem ceeb ntawm kev tsav tsheb rau kev txhim kho lub zog hauv tsev. Los ntawm qhov kev xav ntawm ib tus neeg siv hluav taws xob, kev siv hluav taws xob ib tus neeg ntawm lub teb chaws Yelemees / USA / Nyiv / Australia yuav yog 7,035 / 12,994 / 7,820 / 10,071 kWh raws li xyoo 2021, uas yog 1.8 / 3.3 / 1.99 / 2.56 per capita ntawm Tuam Tshoj. Kev siv hluav taws xob (3,927 kWh) tib lub sijhawm. Los ntawm qhov kev xav ntawm cov nqi hluav taws xob, cov nqi hluav taws xob hauv tsev nyob hauv cov cheeb tsam tsim kho thoob ntiaj teb kuj tseem ceeb dua. Raws li kev txheeb cais los ntawm Ntiaj Teb Petrol Nqe, qhov nruab nrab nqi hluav taws xob hauv tsev nyob hauv lub teb chaws Yelemees / United States / Nyiv / Australia thaum Lub Rau Hli 2020 yog 36/14/26/34 xees/kWh, uas yog 4.2/1.65/3.1/4 npaug ntawm Tuam Tshoj lub tsev. tus nqi hluav taws xob (8.5 xees) nyob rau tib lub sijhawm. Case 1:Australia Residential solar home power systems Australia tus nqi hluav taws xob nruab nrab muaj ntau qhov sib txawv, nyob ntawm qhov loj ntawm koj lub tsev thiab cov khoom siv uas koj siv txhua hnub. Txawm li cas los xij, qhov nruab nrab kev siv hluav taws xob hauv teb chaws Australia yog 9,044 kWh hauv ib xyoos lossis 14 kWh ib hnub. Hmoov tsis zoo, hauv peb lub xyoos dhau los, cov nqi hluav taws xob hauv tsev tau nce ntau dua $ 550. Cov khoom siv hluav taws xob hauv tsev thiab lub zog muaj nyob hauv cov lus hauv qab no:
