How to Use the RV Solar Calculator

Planning an off-grid RV adventure requires a reliable power setup. Our RV Solar Calculator helps you determine exactly what you need without the complex math.

1

Enter Panel Wattage

Input the total wattage of the solar panels you plan to install or currently own.

2

Input Battery Capacity

Enter your battery bank's total Amp-Hours (Ah). This tool assumes a standard 12V system.

Why Inverter Efficiency Matters

When converting 12V DC battery power to 120V AC power for household appliances (like laptops, microwaves, or TVs), some energy is lost as heat. Factoring in inverter efficiency (typically 85-90%) ensures realistic runtime estimates.
