I should have been more specific of what we have and what we plan on doing. Our travel trailer is a 2022 Microlite 21FBRS. It came with a 190 watt solar panel on the roof with a 1000 watt inverter. We plan on spending January and February in Arizona and expect to do dry camping some of the time, especially at Quartzsite. My main concern is to keep my refrig running. It is a residential 12 volt rated at 11 Amps. How many watts of portable solar panels do I need in addition to the 190 Watts panel on my roof? the trailer has a solar panel plug so it it ready for additional solar panels. And I will use the stove to make my coffee so I wont need power for that. Maybe a little TV watching and interior 12 volt lights.
You need to know the duty cycle on the fridge. Or do three days of monitoring of all energy used. That may allow proper sizing of the battery bank and charging systems.
If the lights are not led--change them. It is far cheaper to conserve than to create power.
