I don t beleve in perfect ratios for solar.
Factorio optimal solar layout.
Have a browse through the images for design ideas or download the designs from the blueprint book section at the end.
That is why that electrical grid uses 8 solar panels and 6 accumulators.
I leave a space to walk between.
Solar panels and accumulators optimal ratio.
And there you go an optimal real system of solar panels and accumulators for any network.
Plop a sub station down and fill it with solar pannels.
Now that factorio 1 0 has released i felt it s time to get back in the game to fix the old designs and maybe make something new.
Using n s 8 in the second equation n a is calculated at 5 62 which rounds up to 6.
Furnace starting setup a simple compact smelting block suitable for the beginning of the game.
The build has the perfect ratio of solar panels to accumulators is nearly symmetrical and tilable.
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.
Though in all honesty you probably aren t ready for solar panels yet if the cost bothers you.
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.
Just add as needed for each.
