I don t beleve in perfect ratios for solar.
Factorio perfect solar layout.
Nice work though i know these things are not that easy to design this is the last one i came up with but it uses only 1 roboport.
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.
I took to my sandbox editor and threw together a basic design checked it for ratios and found it a perfect 84 accumulators and 100 solar panels.
Solar panels and accumulators optimal ratio.
Though in all honesty you probably aren t ready for solar panels yet if the cost bothers you.
And slightly over the ratio instead of under is the way to go.
Source this setup puts all 4 science packs on one belt making it easier to grab the science packs from the belt to the labs and looking pretty chaotic and cool.
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.
Plop a sub station down and fill it with solar pannels.
The ideal ratio is 0 84 accumulators panel.
Just add as needed for each.
I leave a space to walk between.
This so sums up factorio perfectionism and practicalism.
There are either 5 36 extra accumulators or 6 38 missing solar panels.
This layout has 170 accumulators and 196 panels.
More accumulators than needed helps safeguard from unexpected night spikes more solar than can be accumulated gets all wasted.
Overall this design has a continuous power rating excluding roboport drain of 8 232mw.
