Install For Outdoor Panel.

I began my energy monitoring journey a few months a go with some smart plugs. Now I would like to upgrade to a monitor in my breaker panel. The issue I might have is that my breaker panel is outside. Does anyone have advice or pictures of outdoor panel installs. I am not a huge DIY person when It comes to electrical so I am going to contact a few electricians to get quotes for install. But I want an idea of what it should look like and if it is possible.
