Ubushobozi ni ingano y'amashanyarazi yose bateri y'izuba ishobora kubika, ipimwa mu masaha ya kilowatt (kWh). Bateri nyinshi z'izuba zo mu rugo zagenewe "guhagarara mu buryo buhuriweho," bivuze ko ushobora gushyiramo bateri nyinshi hamwe na sisitemu yawe yo kubikamo imirasire y'izuba kugira ngo ubone ubushobozi bwiyongereye.
Nubwo ubushobozi bukubwira ingano ya bateri yawe, ntabwo bukubwira ingano y'amashanyarazi bateri ishobora gutanga mu gihe runaka. Kugira ngo umenye neza, ugomba no gusuzuma ingano y'imbaraga za bateri. Mu bijyanye na bateri zikoresha imirasire y'izuba, ingano y'amashanyarazi bateri ishobora gutanga icyarimwe. Ipimirwa muri kilowatts (kW).
Bateri ifite ubushobozi bwo hejuru n'ingufu nkeya yatanga amashanyarazi make (ahagije gukoresha ibikoresho bike by'ingenzi) igihe kirekire. Bateri ifite ubushobozi bwo hasi n'ingufu nyinshi ishobora gukora urugo rwawe rwose, ariko mu masaha make gusa.
