Find sand deposits in Solarpunk on the northern islands, then keep your drill running with solar panels, a windmill, and a battery for night or rainy weather.
In Solarpunk, finding the sand is the easy half. The deposit sits out on the northern islands, but a drill parked on top of it does nothing without a steady power supply — and that supply drops the moment the sun goes down or the weather turns. So this splits into two questions: where the sand-and-stone deposit actually is, and how to wire up enough power that the drill keeps mining through the night and the rain.
In Solarpunk, sand comes from a sand-and-stone deposit on one of the small islands in the northern part of the map, and the real job is keeping your drill powered with solar panels, plus a windmill and a battery to cover night and rain.
Where the sand deposit sits on the map
Head to the northern part of the map and look for a small island off to the right of the robot. That is where the sand-and-stone deposit is in this setup — it yields both sand and stone from the same mining spot, so you are not hunting for a separate sand-only node.
Reaching the outer islands at all is tied to exploration progression — the world is split into small sky islands, and getting to the further ones means upgrading your airship before the deposit is even in reach.
How to power a drill on the sand deposit in Solarpunk
STEP 1/4
Place your solar panels
Drop solar panels next to the deposit — early on, two panels can be enough to run the drill as long as it isn’t raining.
STEP 2/4
Add a windmill once unlocked
Late game, or as soon as you unlock it, set a windmill down beside the panels so you aren’t relying on sunlight alone.
STEP 3/4
Drop a battery to bank surplus
Place a battery so spare energy is stored instead of wasted, then drawn back out when generation dips.
STEP 4/4
Connect a drone after unlocking
Once drones are unlocked, hook one up to the same setup so the operation keeps moving.
All three power sources — solar panels, the windmill, and the battery — can be wired together on the one build, and that combined setup is what keeps the drill fed when any single source falls short.
What each power source adds to the build
| Power source | What it does / when to use it |
|---|---|
| Solar panel | Your daytime workhorse — generates while the sun is up, but output falls in poor light and stops at night. |
| Windmill | A late-game unlock that keeps generating when sunlight is weak, covering the gaps solar leaves. |
| Battery | Banks spare energy while you’re producing a surplus, then feeds it back to the drill through night and rain. |
| Drone | Unlocked later — connect it into the same build to keep the mining operation running. |
Think of it as layers rather than alternatives. Panels carry the daylight load, the windmill props you up when the light is bad, and the battery is the buffer that turns a daytime surplus into overnight uptime. Stacking all of them is what makes the deposit something you can leave running.
Always wire a battery into the build — without one, the drill simply stops the moment the sun drops or it starts raining, since panels alone have nothing to fall back on.
Putting the mined sand to use
Sand feeds back into crafting and building, so a reliable deposit run isn’t just busywork — it’s stocking the resource a chunk of your construction depends on. The most common sink is the Greenhouse, which eats a lot of sand to get started.
Frequently Asked Questions
Is this a Solarpunk thing or a Grow a Garden 2 mechanic?
This is a Solarpunk mechanic. Sand deposits and the drill-and-power setup belong to the standalone early-access game Solarpunk — they are not a feature of the Roblox farming game Grow a Garden 2, which is built around crops, seeds, and pets with no documented sand mining. Any mapping of “sand deposits” onto Grow a Garden 2 is speculation, so if you’re searching there, you’re in the wrong game.
Why does my drill stop at night or when it’s raining?
Because solar panels can’t generate without strong light. At night they shut down almost entirely, and heavy rain drops their output too — so a drill running on panels alone simply halts until the weather clears or the sun returns. The fix is to store energy ahead of time in a battery (and add a windmill) so there’s something to draw from when the panels go quiet.
Do I really need a windmill and a battery, or are solar panels enough?
Early on, a pair of solar panels can carry the drill — as long as it isn’t raining. The trouble is that night and bad weather will stall a panels-only build. A battery banks your daytime surplus so the drill keeps going after dark, and a windmill (a later unlock) keeps generating when the light is poor. So panels can be enough to start, but the battery and windmill are what make the operation reliable. Exact energy figures floating around — roughly 100-ish per panel, with the drill drawing somewhere around 120–200 — come from a single showcase run and swing with time of day and weather, so treat them as ballpark rather than fixed numbers.
What do I use the sand for once I’ve mined it?
Sand goes into crafting and building. The clearest use is the Greenhouse, which takes a good amount of sand to construct.
