I don t beleve in perfect ratios for solar.
Factorio best solar panel layout.
Plop a sub station down and fill it with solar pannels.
You need 17 solar panels for each steam engine running at max capacity.
Or more precisely you need power consumption in w 30 kw solar panels.
Note your roboports will be closer together here which isn t necessarily a bad thing depending on your base.
This so sums up factorio perfectionism and practicalism.
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.
Though in all honesty you probably aren t ready for solar panels yet if the cost bothers you.
During daylight hours every panel provides the maximum power level 60kw.
Overall this design has a continuous power rating excluding roboport drain of 8 232mw.
For each 5 solar panels you need 3 accumulators.
Generated power will increase decrease linearly during dusk and dawn and no power is produced at night.
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.
The ideal ratio is 0 84 accumulators panel.
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.
There are either 5 36 extra accumulators or 6 38 missing solar panels.
Something to consider is that many people like replacing a solar panel with a radar in.
I leave a space to walk between.
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.
Just add as needed for each.
Solar panels and accumulators optimal ratio.
Also there are more capacitors than panels because capacitors are far more important.
