How Long Can I Camp Off-Grid?
Estimate how many days you can camp off-grid, comparing no solar, reduced (cloudy) solar and good solar scenarios.
How Many Days Can You Camp Off-Grid?
No solar
2.4 days
Reduced solar (cloudy)
4.3 days
≈360Wh/day generated
Good solar
54.3 days
≈765Wh/day generated
Autonomy = usable battery capacity ÷ (daily use − daily solar generation). If solar generation meets or exceeds your daily use, the battery stops depleting further and autonomy becomes effectively indefinite — shown as such above where applicable. Real solar generation varies day to day, so treat this as a planning range rather than a guarantee.
Why three scenarios?
Solar generation is never perfectly predictable — a few overcast days can significantly cut your expected recharge. Comparing no solar, reduced solar and good solar scenarios gives you a realistic range to plan around, rather than a single optimistic number that assumes perfect conditions every day.

Frequently Asked Questions
How many days can I camp off-grid without solar?+
Purely a function of your usable battery capacity divided by your daily energy use — enter your figures above for a specific answer. Reducing daily use (e.g. running the fridge more efficiently, cutting non-essential loads) extends this directly.
Does solar really make that much difference?+
It can be the difference between a battery that only lasts a couple of days and one that lasts indefinitely, if your solar generation meets or exceeds your daily use — see the comparison above with your own numbers.
