RV & Van Life Solar Calculator 🚐

How to Use the RV & Van Life Solar Calculator

Enter your daily power consumption (Wh), battery voltage (12V or 24V), days of autonomy, and depth of discharge. Formula: Battery capacity (Ah) = daily Wh × autonomy days / (DoD% × voltage).

Enter peak sun hours for your travel region and system efficiency. Formula: Required panel watts = daily Wh / (peak sun hours × efficiency). The calculator also shows how many 100W, 200W, or 400W panels you need.

RV defaults: 12V system, LiFePO4 DoD 80%, 2 days autonomy. Use the regional presets for sun hours: sunny regions ~6h, temperate ~4.5h, cloudy ~3h. Size up your battery and panels by 20% for safety margin.
