I was searching the meanings of these two words:
alone and solo
And, (according to the source), both shares the same meaning:
alone; without other ​people.
Both words sounds for me interchangeable in usage "speaking, writing, etc".
As the title says: what is the difference between solo and alone? and there are rules for the usage of each one of them?
The answer should show references and example usages for learning purposes (i.e: for get a better understanting about its usage).

They have similar meanings, but they are not used in the same semantic contexts, and they cannot both be used in all the same syntactic contexts.
solo is mostly used to speak only of actions; alone is also used to speak of anything physically isolated.
solo can be used as a noun ("a drum solo") or verb ("Rich soloed the third chorus"); alone cannot.
solo is used as an attributive adjective before its head noun ("a solo performance"); alone is used as an attributive adjective after its head ("John alone was successful").
alone can be used as an adjectival predicate complement ("Amy was now alone"); solo is very rarely used this way.
It is really only as adverbs that their uses overlap: "John acted alone", "John acted solo".
