You have to find a new place to locate the whole service entrance elsewhere on the building. That may, or may not be easy to do. You have to re-route all the circuits that originate in that panel to the new location. That means a lot new cable from the first junction box in the existing circuits to the new main service panel. Cost depends on accessibility of the existing circuits.

Things you can do to make it look better without moving it.

1. Move the outlet box over to above the pet door.
2. Re route the conduit/loose wire by the outlet box to run underneath the deck.
3. Clean up various loose wires by cable tying them to the conduit.
4. Paint all the conduit and boxes to match the wall. (not the glass on the meter)

I think it just looks messy and can be cleaned up a bit then it wont look so bad. Otherwise your looking at minimum of 2 grand to move that.
