Hi,
and welcome,
Genreally if your solenoids are clicking then it's getting SOME power to the starter.. however it IS worth double checking the wiring from the battery to the starter,
when you turn the key do the ignition lights on the dashboard stay BRIGHT or do they DIM?,
if they stay BRIGHT then it's probably a poor connection somewhere, battery's power NOT going anywhere !!
you've not given any mechanical details,
I would be tempted check all fluid levels - then to push / tow start the car, just to determine it's NOT an engine issue..,
