Cov cua daj cua dub tsis ntev los no uas tshwm sim nyob rau sab qaum teb Ltalis tau ua rau muaj kev puas tsuaj uas cov xwm txheej tam sim no thiab cua daj cua dub tuaj yeem ua rau cov tshuab photovoltaic. Ntau tus tswv tsev tau tshaj tawm cov duab ntawm cov nroj tsuag puas hauv kev sib raug zoo, qhia meej txog kev ua phem ntawm hailstorms thiab, qhov tseem ceeb tshaj plaws, qhov loj ntawm hailstones, uas qee zaum txawm mus txog 20 cm inch.
Tab sis cov nplej loj npaum li cas yuav tsum tau ua kom puas lub tshuab photovoltaic? Dab tsi tuaj yeem suav tias yog qhov tseem ceeb tshaj qhov kev puas tsuaj loj?
Peb sim teb cov lus nug no los ntawm kev tshem tawm daim ntawv tshaj tawm xyoo 2019 los ntawm Vrije Universiteit Amsterdam (VUA) uas tau tshawb xyuas cov ntaub ntawv pov hwm kev puas tsuaj ntawm keeb kwm hailstorm uas tshwm sim thaum Lub Rau Hli 2016 hauv Netherlands.

Tom qab ob peb lub hlis, txawm li cas los xij, cov cheeb tsam puas tuaj yeem pib pom lub zog poob sai, thiab tom qab li ib xyoos cov micro-cracks kuj pom nyob rau sab nraud ntawm lub vaj huam sib luag. Tag nrho cov kev puas tsuaj ces txo lub neej ntawm lub hnub ci vaj huam sib luag.
Kev taw qhia ntawm lub ru tsev txheeb ze rau cov kev taw qhia ntawm lawg tuaj yeem cuam tshuam rau kev puas tsuaj los ntawm lawg rau hnub ci vaj huam sib luag, cov kws tshawb fawb tau piav qhia, sau tseg tias qhov tseem ceeb no tuaj yeem txiav txim siab ntau dua li qhov loj ntawm hailstones.
Tom qab ntawd muaj qee cov pov thawj pom tseeb - ntawm qhov tod tes, tsis tseem ceeb heev - tias txawm tias lub kaum sab xis ntawm lub hnub ci vaj huam sib luag tau teeb tsa tuaj yeem cuam tshuam kev puas tsuaj rau lub hnub ci vaj huam sib luag. Ib qho kev xav ntau dua, raws li cov lus xaus ntawm cov kws tshawb fawb, yuav pab txo qis kev puas tsuaj.
Txoj kev tshawb no kuj qhia tau hais tias qhov zaus ntawm hailstorms yog nce nyob rau hauv cov teb chaws Europe thiab lub Netherlands, raws li yog kev puas tsuaj los ntawm hailstorms. Qhov no qhia tau hais tias cov khoom raug, xws li cov hnub ci vaj huam sib luag, tuaj yeem ua rau muaj kev cuam tshuam ntau dua yav tom ntej.
"Hail kev pheej hmoo thiab qhov tsis zoo ntawm lub hnub ci vaj huam sib luag rau lawg yuav tsum suav nrog cov qauv kev pheej hmoo thiab cov tswv yim hloov pauv huab cua," cov kws tshawb fawb Dutch tau xaus.
