Portable solar panel — Factorio Production Calculator
Portable solar panel is crafted in the assembling machine in 10 seconds, producing 1 per craft from 1 × Solar panel, 2 × Advanced circuit, 5 × Steel plate. At 60 per minute you need 20 assembling machines, and the chain behind it draws on 4 raw resources: iron ore, petroleum gas, copper ore, coal.
Production chain for 60 Portable solar panel / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Iron plate | 4,140 | 220.8 | Furnace |
| Copper cable | 3,900 | 32.5 | Assembling machine |
| Copper plate | 2,250 | 120 | Furnace |
| Electronic circuit | 1,140 | 19 | Assembling machine |
| Steel plate | 600 | 160 | Furnace |
| Plastic bar | 240 | 2 | Chemical plant |
| Advanced circuit | 120 | 24 | Assembling machine |
| Portable solar panel | 60 | 20 | Assembling machine |
| Solar panel | 60 | 20 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Iron ore | 4,140 |
| Petroleum gas | 2,400 |
| Copper ore | 2,250 |
| Coal | 120 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Portable solar panel recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 10 s | 1 | Solar panel × 1, Advanced circuit × 2, Steel plate × 5 |
What the whole chain needs
60 portable solar panels per minute pulls in 8 intermediate products, and the whole tree comes to 618 machines across 3 machine types, fed by 4 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 4,140 per minute, which is 4.6 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses portable solar panel
No base-game recipe consumes portable solar panel — it is an end product. Once you build it, the chain stops here, which makes it a good target if you only want to size the sub-factory that feeds your mall.
What portable solar panel is made from
- Solar panel — 1 per craft
- Advanced circuit — 2 per craft
- Steel plate — 5 per craft
FAQ
How many assembling machines do I need for 60 portable solar panels per minute?
20 assembling machines. One at standard speed produces 3 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does portable solar panel take?
At 60/min the chain consumes 4,140 iron ore per minute, 2,400 petroleum gas per minute, 2,250 copper ore per minute and 1 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
