Where to start with solar power?

We are trying to figure out how many watts of solar panels are on top of our new to us 92 Southwind. They are apx 12" x 48" We also have discovered we have a Magnatek 900 series model 950 50 amp Coverter/Charger. We also have found another inverter in an outdoor compartment where an icemaker used to be installed. It is a Whistler 2000 watt peak, 1000 watt continuous, 115VAC, 60 hz. Our goal is to replace our broken Dometic 2804 refrigerator with a 7.4 cf non-frost free residential unit that will just fit in the openin we think.

Hoping to get any info/advice so that we can use this frige and also maybe some other stuff without having to run the generator or being plugged in!
