Narcissism vs solipsism

A quite simple question. According to the TRP definitions of these words, what is the difference between solipsism and narcissism?

EDIT: I'm gonna try to round up some definitions of solipsism from TRP. Might help.

• Solipsism is personal validation

• Solipsism is apparent when a woman tries to punish her ex by telling him she got pregnant by another man

• Solipsism is a presumption that ones experience is the universal one and it entails indifference to anything external that doesn’t affect them directly and personally

• Solipsism means being mostly concerned with how things and people affect oneself. In other words, their worlds begin and end with themselves.

• Solipsism is when a fat person prefers to be referred to as "normal", "average" or "beautiful".

• Solipsism is relying on personal experience instead of larger, rational, more empirical meta-observations.

• Here is a comment implying that solipsism is a more extreme version of narcissim.
