Kev tsim hluav taws xob photovoltaic muaj lub zog tseem ceeb, kev tiv thaiv ib puag ncig thiab cov txiaj ntsig kev lag luam, thiab yog ib qho zoo tshaj plaws ntsuab zog. Raws li qhov nruab nrab hnub ci nyob rau hauv kuv lub teb chaws, txhim kho ib tug 1-kilowatt faib photovoltaic fais fab nroj tsuag muaj peev xwm tsim tau 1,200 kWh ntawm hluav taws xob nyob rau hauv ib xyoos, txo cov kev siv ntawm cov thee (tus qauv thee) txog li 400 kilograms, thiab txo carbon dioxide. emissions txog li 1 tuj.
Raws li kev tshawb fawb los ntawm World Wide Fund for Nature (WWF): Raws li cov pa roj carbon dioxide emission txo cov nyhuv, txhim kho 1 square meter ntawm photovoltaic fais fab tuag system yog sib npaug rau cog 100 square meters ntawm ntoo. Tam sim no, kev txhim kho cov khoom siv hluav taws xob txuas ntxiv xws li kev tsim hluav taws xob photovoltaic yuav yog ib txoj hauv kev zoo los daws cov teeb meem ib puag ncig xws li smog thiab kua qaub los nag.
