How to calculate solar panel setup?
The battery will not be enough.

Assuming all of your power will go from the battery to the load with 100% efficiency (no losses in the conversion from 12V to 220V), 550W requires the following current output from your battery:

550W / 12V = 45.83A

Your battery is 63AH, so the device can be powered from the battery alone for:

63AH / 45.83A = 1.4 Hours

After which the battery would be completely drained and would have to be fully recharged from the solar panels. 

Solar power at the Earth's surface is (roughly) 1KW/square meter and solar panels are (pessimistically) 10% efficient, so you get 100W/square meter. Again, assuming perfection,  that gives you:

100W / 12V = 8.33A

That means, to power your load ONLY you'd need:

45.83A / 8.33A/Square Meter = 5.5 Square Meters of solar panels.

That's a square area 2.3 meters long on each side (7.5 feet if you swing that way). 

Although, realistically you'd need more area because it's likely you'll need to charge the battery and power the load at the same time at some point.

There's not enough information in your question to suggest what system parameters might work for you, but my guess is it's a large, expensive system.
