Off-Grid Solar Simulator

Search real solar panels, batteries, charge controllers, and power stations. Add appliances — from LED lights to an electric pickup truck — and watch live energy flow across a simulated day.

All power, battery, and cost figures are physics-based estimates for planning intuition. Real-world performance varies with weather, temperature, wiring losses, and manufacturer tolerances.

Which devices will you power?

Check each device you plan to run. Adjust daily hours as needed.

No devices selected.

How much sun do you get?

Pick the option closest to your install location.

Days of backup without sun?

How many cloudy or rainy days should your battery carry you through?

System voltage preference

Not sure? Auto-recommend picks the right voltage for your load size.

What's your budget priority?

Choose how the wizard should balance cost vs. performance.

Real parts & appliances — live energy simulation

Model: solar position → irradiance → array output (real V/A) vs. appliance load, balanced against battery storage over a simulated day. Truck and tiny-house loads are estimated from miles driven and outdoor temperature. All figures are physics-based estimates for planning intuition.
