How did Mon-el have his powers in the eclipse. He is supposed to be a yellow sun battery roo like supergirl so how was he flying round while Kara was unable to stand up?!

Can anyone tell me how Mon-El had his powers when the eclipse happened and Supergirl could hardly stand up never mind fly around and fight like Mon-El did.
