Hi,
You can find decent prices on solar panels here.
SunElec.comIf you install about 400 - 600 watts of solar panels, it can normally keep up with the home refrigerator in a RV. Many are Samsung, as they are more tolerant to the inverter power and also very energy efficient.
You would need at least 6 golf cart batteries, or 3 of the 120 pound 8D batteries to run the refrigerator for a couple of days without needing to run the generator a lot.
Personally I would rather have a propane refrigerator, and then be able to dry camp for 2 weeks using a 400 watt solar system to recharge the RV during the day, with the refrigerator using about 35 amp hours daily. The residential refrigerator can use around 100 amp hours daily (1200 watts) and this will require more solar panels, or running the generator more often.
Fred.
