Solarpunk Power Grid Setup for Late Game

By hour 15, your starter solar panel is not enough. This guide shows you the 12-machine factory blueprint — a redudant, expandable grid that never blacks out, scales to 4-player co-op, and is easy to debug.

The 4 Principles

1. Two sources, one grid. Solar + wind turbine, run in parallel.
2. One battery per machine. No exceptions. Power outages are silent killers.
3. Star pattern, not daisy-chain. One splitter per machine group, never chain 3+ machines.
4. Heavy cable everywhere. The copper cost is worth it for the 5x power capacity.

Load Calculator (Per Machine)

A 12-machine factory averages 100W — under the 200W capacity of two solar panels plus a wind turbine, with a 50% head-room for expansion.

The 12-Machine Blueprint

1. Place 2 solar panels on the south-facing wall, 1 block apart.
2. Place 1 wind turbine on the highest point of the base.
3. Run a heavy cable from each to a central power room (3×3 enclosed).
4. Inside the power room, place 4 batteries in a row.
5. Run 3 splitters in a line, each fed by a heavy cable from the battery bank.
6. From each splitter, run 4 heavy cables to a machine group (3 splitters × 4 = 12 machines).
7. Add 1 bridge at every cable cross-over.
8. Test at night: all 12 machines should run on battery for 8+ hours.

Debugging a Failing Grid

1. Open the power overlay (P key). Machines in red are not powered.
2. Walk back along the cable to the nearest splitter. If the splitter is unpowered, the grid is broken upstream.
3. Check for bridges at every cross-over. Missing bridge = silent short.
4. If all upstream is fine, replace the basic cable to the failing machine with heavy cable.
5. Last resort: place a 5th battery directly next to the failing machine.
