Managing power in Solarpunk feels straightforward until the moment your drill goes dark and you have no idea why. The energy system has real load math behind it, and once you understand the numbers, most outages become predictable and preventable. This guide covers every power value you need, the right build order, placement rules for solar panels and windmills, and how switches turn a messy grid into something you can actually control.
Power values every player should know
Before placing a single cable, get these numbers in your head. They are the foundation of every decision you will make about your grid.
| Device | Power Value | Practical Impact |
|---|---|---|
| Solar Panel | +10 per panel | Light loads are fine; heavy machines need many panels or stored power |
| Battery | 95 storage each | Two batteries give 190 total, enough to cover night and rain dips |
| Drill | -120 power | One of the heaviest early loads in the game |
| Sprinkler | -40 power each | Three sprinklers equal the same draw as one drill |
| Advanced Dock | -100 power | Convenient for flying, dangerous on an already strained grid |
The drill is the number that surprises most players. At 10 power per solar panel, a single drill demands the equivalent output of 12 panels before you account for clouds, nighttime, sprinklers, or a powered dock sitting on the same cable network. That is not a reason to avoid drills. It is a reason to plan before you connect one.

What should you build first for power?
The temptation is to stack solar panels and hope for the best. The smarter move is to unlock the tools that let you read your grid before expanding it.
| Unlock | Priority | Why It Matters |
|---|---|---|
| Energy Workbench | Mandatory | Opens solar panels, cables, Network Display, drill, and switches |
| Solar Panels | Very high | Replaces wood fuel during daylight hours |
| Network Display | Very high | Shows live generation, consumption, and storage data |
| Drill | High | Automates ore but carries a 120-power load |
| Battery | High after Tier 2 | Covers night, rain, and short production gaps |
| Windmill | High after Tier 3 | Adds a non-solar source for mid-to-late-game stability |
The clean early route looks like this:
- Trade for the Energy Workbench blueprint and build it at your base.
- Research and craft solar panels.
- Run enough cables to connect your first powered area.
- Place a Network Display before adding any heavy machines.
- Only then connect a drill or expand your farm automation.

Why does your power keep shutting off?
Most outages trace back to one of four causes: no sunlight, too much load, missing storage, or a cable network that is accidentally split into separate islands.
| Problem | Likely Cause | Fix |
|---|---|---|
| Everything stops at night | Solar panels produce nothing without sunlight | Sleep through early nights; add batteries once machines matter |
| Power drops during rain | Solar generation becomes unreliable in bad weather | Add batteries, switches, and eventually windmills |
| Drill will not run | 120-power load exceeds current generation | Check Network Display, reduce other loads, build more panels |
| Sprinklers drain batteries | Multiple sprinklers running during rain or low-solar periods | Put sprinklers on a switch, turn them off when not needed |
| One machine shuts off despite a healthy-looking grid | Cable network is split into separate groups | Keep one main network early; split only when you know each branch's needs |
If your base works in sunshine and fails at night, that is the solar system behaving correctly. Early on, sleeping past nighttime is the simplest solution. Batteries are the permanent fix once your machines need to run around the clock.
How many solar panels do you need for a drill?
The math is blunt. One drill uses 120 power. One solar panel produces 10 power. That means a drill alone requires the output of 12 panels at full capacity, and full capacity only happens in clear daytime conditions.
| Load Combination | Total Power Draw | What You Need |
|---|---|---|
| Drill only | 120 | 12 panels minimum, more with weather losses |
| Drill + 1 sprinkler | 160 | Separate grids or significant battery backup |
| Drill + 3 sprinklers | 240 | Batteries and switches before expanding further |
| Drill + Advanced Dock | 220 | The dock competes directly with mining power |
For your first drill setup:
- Check the Network Display before connecting the drill.
- Turn off sprinklers or other optional machines while mining is your priority.
- Add a Battery once Tier 2 opens.
- Consider a remote mining outpost on the ore island rather than running everything from your main base.

When should you build batteries?
Build your first battery as soon as your base has at least one powered machine you cannot afford to lose overnight. That usually means the moment you connect a drill, run more than one sprinkler, or start using the Advanced Dock.
| Battery Count | Total Storage | Best Use |
|---|---|---|
| 1 | 95 | Buffer for a small solar grid or light automation |
| 2 | 190 | Practical Tier 2 target once drills and sprinklers are running |
| 4 | 380 | Stronger mid-game buffer for mixed loads and bad weather |
The wrong move is waiting until your base is large and then chasing every outage with another solar panel. Storage and generation need to grow together.

How to place solar panels and windmills correctly
Bad placement can make a solid power setup feel half as strong as it should be.
Solar panels need open sky. Keep them away from roofs, tall walls, and cramped corners where base structures create shadow. Staggering panels in rows instead of packing them into a dense block also makes future expansion cleaner.
Windmills need breathing room. A rough 5 to 10 meter gap between turbines is a safe planning rule. Jamming windmills into a crowded crafting zone reduces their effectiveness and makes your energy area harder to read.
Keep your main energy zone open from the start. You will almost certainly add more panels, batteries, windmills, and switches as the game progresses, and cramped early layouts make that expansion painful.

How do switches stop power waste?
Switches are the most underused tool in the energy system. They let you cut power to one branch of your grid without touching the rest, which means you can stop sprinklers from draining batteries during rain without also killing your drill.
| Power Problem | Switch Fix | Why It Works |
|---|---|---|
| Sprinklers drain batteries during rain | Put sprinklers on a switch-controlled line | Turn them off when crops are already watered or storage is low |
| Drill competes with base machines | Give the drill its own controllable branch | Pause mining when the base needs power elsewhere |
| Advanced Dock overloads the grid | Keep the dock separate from farm and mining loads | Dock power is optional; drill and sprinkler power often is not |
| Remote outpost behaves unpredictably | Keep outpost on its own local grid | One drill and one battery bank is much easier to diagnose than a long cable chain |
The setup is simple:
- Run sprinklers on their own cable branch.
- Add a switch before that branch.
- Turn the sprinkler line off during rain or low-power periods.
- Give the drill its own controllable line if it competes with farm machines.
- Use sensors and logic blocks later when you want automation instead of manual switching.
Controlling demand is just as valuable as adding more generation. More solar panels help, but a well-switched grid often solves the same problem without the material cost.
How to set up a remote mining outpost
Once you have access to an ore island, stop flying out to hand-mine the same nodes repeatedly. A simple drill outpost turns those trips into quick pickup runs.
Bring:
- A drill
- Enough local solar panels to power the drill
- Cables
- A battery if Tier 2 is unlocked
- Repair supplies for your airship
- Food and water for the trip
Keep the outpost on its own local network. One drill, one battery bank, and a small solar setup is far easier to troubleshoot than a cable chain running all the way back to your main base. Collect ore manually at first, then let transport drones handle the supply chain once they are available.
For the full airship setup needed to reach ore islands, the Solarpunk airship guide covers the Crashed Airship Component, dock construction, and copper requirements.

When should you build windmills?
Windmills are a mid-to-late-game answer, not an early fix. Prioritize them after Tier 3 when your base has grown past what solar and batteries can reliably cover.
Build windmills when:
- Your farm runs multiple sprinklers and batteries keep draining
- Drills compete with base machines for the same power
- The Advanced Dock is part of your regular grid
- Rain and night still interrupt your routine despite having batteries
Cosmetic upgrades and comfort unlocks are fine, but power stability affects every other system. If your base is still losing power in bad weather, windmills come before lights and decorations.
Recommended power build order
Follow this sequence and the energy system stops feeling like a mystery:
