A single solar panel does not need a fuse/breaker; however, you are free to use one. The panel label should indicate a max fuse rating. Use that.
If you use suitable wires and plan to use 60A, fuses/breakers should be sized for 1.25X max current, so 75-80A depending on what's available.
Cheap fuses and breakers are not recommended. Many cheap products on Amazon fail to meet rated performance.
