It will produce enough juice for lights radio, cpap, fan for fridge using propane and pump for toilet flushing and water. No ac and no fridge.
Here in the Pac NW most State Parks, Nat Forest, and other boondocking camping areas are tree covered and permanent mounted Solar Panels yield little power.
This is why I opted for a "suitcase setup" along with a long extension cord to carry the power to the trailer from wherever I find sun.
I also find that I can make do with smaller panels as I can track the sun even when there is no shade. By doing that while at Quartzsite last month I didn't need the generator to charge batteries as my 160 watt "suitcase" kept up with my needs.
