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.

Can I run AC on solar?

Briefly. Sustained AC requires generator or shore power. Boondockers typically don't run AC continuously.

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.

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.
