RV solar power for boondocking
Watts, batteries, and the practical reality of off-grid RV power.
Solar panels enable extended boondocking without generator use. Practical setup sizes range from 200W (modest) to 1,200W (boondocker-grade). Battery storage is the equally-important other half — typically 200-600 amp-hours of lithium iron phosphate (LiFePO4). This guide covers the practical sizing reality.

How much solar do I need to boondock indefinitely?
Depends on your power consumption. Light use (lights + phones + minimal device charging): 200-400W solar + 100 Ah LiFePO4 = adequate. Moderate use (laptops + cooking + occasional refrigeration): 600-800W solar + 400 Ah LiFePO4. Heavy use (AC, electric heating, Starlink continuous): 1,200W+ solar + 600+ Ah LiFePO4. The constraint is that AC running off battery quickly depletes regardless of size; AC is the major boondocking limit.
- Light: 200-400W + 100Ah
- Moderate: 600-800W + 400Ah
- Heavy: 1,200W+ + 600Ah
- AC use depletes battery quickly
- LiFePO4 battery preferred over lead-acid
What RV solar industry + community doesn't tell you
Solar industry marketing emphasizes wattage. Real boondocker calculations involve daily watt-hours, battery storage, and cloudy-day reserves.
The honest summary: 600W solar + 400 Ah LiFePO4 is the sweet spot for most boondockers.

Frequently asked questions
- Can I run AC on solar?
- Briefly. Sustained AC requires generator or shore power. Boondockers typically don't run AC continuously.
