Issue with 160W Solar Panel

I am charging my EcoFlow Delta 3 power station using a 160W solar panel. Even on completely sunny days with the panel placed in direct sunlight, the input power never reaches 100W. It consistently ranges between 80W and 90W.Has anyone else encountered this with their setup? Is it normal to get this wattage from a 160W panel, or could there be an issue with my panel, cables, or settings? Any insights would be greatly appreciated!
