You need 17 solar panels for each steam engine running at max capacity.
Factorio best solar panel layout.
Though in all honesty you probably aren t ready for solar panels yet if the cost bothers you.
Note your roboports will be closer together here which isn t necessarily a bad thing depending on your base.
I leave a space to walk between.
Or more precisely you need power consumption in w 30 kw solar panels.
This layout has 170 accumulators and 196 panels.
Solar panels and accumulators optimal ratio.
Just add as needed for each.
Something to consider is that many people like replacing a solar panel with a radar in.
Remember if you don t have enough solar panels things simply don t run as fast but if you don t have enough capacitors your entire base will shut down at night which can and will kill you in the right circumstances.
This means one solar panel produces an average of 42 kw over one day and night cycle.
Keep in mind that these numbers are approximate you may want to have a buffer for laser turrets if nothing else.
This so sums up factorio perfectionism and practicalism.
Haven t seen this design posted anywhere so here is yet another 0 15 solar panel layout this solar panel layout has a roboport only uses 4 substations has the exact 0 84 ratio 84 accumulators 100 solar panels and is symettrical.
Overall this design has a continuous power rating excluding roboport drain of 8 232mw.
During daylight hours every panel provides the maximum power level 60kw.
Plop a sub station down and fill it with solar pannels.
This tutorial covers solar panel arrangements to use at various stages of the game including the building of the massive ratio perfect array from this foru.
There are either 5 36 extra accumulators or 6 38 missing solar panels.
As for which to actually pick i d say it s up to your preference cilya s design with accumulators instead of a roboport is the only one with perfect 0 86 ratio among popular designs used by factorio players.
Solar panels are an unlimited source of free energy that produce no pollution.
The ideal ratio is 0 84 accumulators panel.
The optimal ratio is 0 84 21 25 accumulators per solar panel and 23 8 solar panels per megawatt required by your factory this ratio accounts for solar panels needed to charge the accumulators this means that you need 1 428 mw of production of solar panels and 100mj of storage to provide 1 mw of power over one day night cycle.
Also there are more capacitors than panels because capacitors are far more important.
