Lub hnub ci hluav taws xob photovoltaic (PV) tau txais txiaj ntsig zoo nyob rau xyoo tas los no vim nws qhov zoo dua lwm qhov ntawm hluav taws xob. Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm lub hnub ci PV yog lawv cov kev ua haujlwm siab hauv kev hloov lub hnub ci rau hauv hluav taws xob. Txawm hais tias qhov ua tau zoo ntawm PV hnub ci tshuab nws txawv nyob ntawm qhov sib txawv, xws li hom hnub ci vaj huam sib luag, huab cua puag, thiab qhov chaw ntawm lub cev, qhov ua tau zoo ntawm PV hnub ci tshuab niaj hnub tau txhim kho tau ntau xyoo dhau los.
Ib qho tseem ceeb cuam tshuam rau kev ua haujlwm ntawm lub hnub ci PV yog hom hnub ci vaj huam sib luag siv. Muaj ntau ntau hom hnub ci vaj huam sib luag muaj nyob hauv khw, suav nrog monocrystalline, polycrystalline, thiab nyias zaj duab xis hnub ci vaj huam sib luag. Ntawm cov no, monocrystalline hnub ci vaj huam sib luag paub txog lawv cov kev ua tau zoo dua, vim lawv tau tsim los ntawm ib leeg siv lead ua silicon. Cov vaj huam sib luag no tuaj yeem hloov mus txog 23% ntawm lub hnub ci rau hauv lub zog siv tau, thaum cov vaj huam sib luag polycrystalline muaj qhov ua tau zoo ntawm 20%.
Lwm qhov tseem ceeb uas cuam tshuam rau PV solar system efficiency yog huab cua. Txawm hais tias lub hnub ci vaj huam sib luag tseem tuaj yeem tsim qee qhov hluav taws xob nyob rau hnub huab cua, lub zog tsim tawm tau qis dua piv rau hnub tshav ntuj. Ib yam li ntawd, lub zog tsim tawm thaum lub caij ntuj no qis dua qhov uas tau tsim thaum lub caij ntuj sov vim qhov qis qis nruab hnub nrig thiab qis dua hnub ci. Txawm li cas los xij, qhov chaw ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov ua tau zoo ntawm lub hnub ci PV systems. Nrog rau kev txhim kho kom zoo, lub hnub ci vaj huam sib luag hauv qhov chaw tshav ntuj tuaj yeem tsim hluav taws xob ntau dua li ob npaug ntawm lub vaj huam sib luag hauv qhov chaw tshav ntuj tsawg.
Ib cag ntawm hom hnub ci vaj huam sib luag thiab cov huab cua puag ncig, kev ua haujlwm ntawm lub hnub ci PV tseem tuaj yeem txhim kho los ntawm kev ua kom lub hnub ci ntau tshaj plaws ntawm cov vaj huam sib luag. Lub kaum sab xis thiab kev taw qhia ntawm lub hnub ci vaj huam sib luag tuaj yeem cuam tshuam rau lub zog ntau lawm. Piv txwv li, nyob rau sab qaum teb hemisphere, panels yuav tsum tig mus rau sab qab teb kom tau txais lub hnub ci tshaj plaws txhua hnub. Qhov zoo tshaj plaws qaij lub kaum sab xis ntawm lub vaj huam sib luag sib txawv nyob ntawm thaj tsam, thiab kho lub kaum sab xis tuaj yeem pab ua kom muaj zog ntau lawm.
Zuag qhia tag nrho, PV hnub ci tshuab muaj kev ua haujlwm siab, uas ua rau lawv muaj txiaj ntsig zoo rau cov khoom siv hluav taws xob. Txawm hais tias qhov ua tau zoo ntawm lub hnub ci PV systems tseem muaj chaw rau kev txhim kho, kev tshawb fawb thiab kev loj hlob tsis tu ncua tau ua kom muaj kev vam meej hauv xyoo tas los no. Raws li hnub ci thev naus laus zis txuas ntxiv mus, nws yuav dhau los ua qhov tseem ceeb ntxiv rau kev siv lub zog hluav taws xob no los pab ua kom tau raws li lub zog xav tau ntawm lub ntiaj teb.
