Rust Electricity Calculator
Add your base's electrical components to see the total power draw and how many solar panels and batteries you need to run it 24/7.

Power Needed
Estimates use ~4× load in solar peak and large batteries (100 rW output). Wind turbines (0–150 rW) can replace some solar for 24/7 power.
Frequently Asked Questions
How is power measured in Rust?expand_more
Power is measured in rW (rust watts). Every consumer draws a set amount of rW, and every source (solar, wind, batteries) provides rW. Your supply must meet or exceed your total draw.
How many solar panels do I need?expand_more
A solar panel produces up to 20 rW at midday only. To run a base 24/7 you need roughly 4× your total load in solar peak, with batteries storing power for the night. The calculator sizes this for you.
How many batteries do I need?expand_more
A large battery outputs 100 rW, so you need at least one large battery per 100 rW of load to carry your base overnight while the panels aren't generating.
Do wind turbines help?expand_more
Yes — wind turbines produce 0–150 rW around the clock (output varies with height and wind), so they can replace some solar for more consistent 24/7 power.
How much power does an auto turret use?expand_more
An Auto Turret draws 10 rW. A base with several turrets plus lights and sensors adds up quickly — use the calculator to size your solar and battery bank.
