FAQ

How many solar panels do I need in Rust?
It depends on your power draw. A single solar panel produces 20 rWm at peak (midday). For 24/7 power, you need roughly 4x your base load in solar panels plus batteries to store overnight power.
How long do batteries last in Rust?
A small battery holds 150 rWm and a large battery holds 600 rWm. How long they last depends on your power draw. A large battery powering 10 rWm lasts 60 minutes after solar stops.
What is rWm in Rust?
rWm stands for "rust Watts per minute" โ€” it is the unit of power in Rust. Think of it like real-world watts. Each device draws a certain rWm and power sources produce rWm.
Do wind turbines work at night?
Yes, wind turbines produce power 24/7 but output varies with wind speed. They produce 0-150 rWm. On average expect around 50-80 rWm in most locations.
