Extensions are installed in control panel from Extension Manager section. Before installation there following checks are performed:

check available space
is extensions directory writable
was extension already installed ( extension upgrade )
does extension support used core version
does hosting support all php modules used by extension
does extension override some controllers/ template files that already overridden by another extension. if two or more extensions override completely same files there will be a conflict, so high priority extension will be used. But, there will be warning in the install about conflict.

Post-install actions

check all files list and sizes
run install process
