Vanlife Power Planner

Start with your lifestyle and climate. The app estimates daily consumption first, then auto-sizes your key electrical components.

Power Profile

Select what you use. Sliders represent average daily use.

Solar + Driving Input

Charging is modeled from panel wattage, sun exposure, and alternator power while driving.

Solar

Sun Exposure

Shading/obstruction override. Applied on top of PVWatts data when precision mode is on.

Use live month/location sun model (PVWatts)?

Estimated sun hours/day: 0.0 hr

Manual assumption (4.8 sun-hr/day baseline).

Alternator Charging

Battery Setup

Set reserve autonomy and test your planned battery bank.

Assumptions File

Download a starter settings file (includes all tunable parameters such as halogenWatts = 40, inverterEfficiencyPct = 92, pvWattsApiKey = "DEMO_KEY"), edit it, and import it.
