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.
Factorio perfect solar layout.
This layout is not made by me.
Plop a sub station down and fill it with solar pannels.
I like it because it embraces the chaos you rarely find in factorio.
This layout has 170 accumulators and 196 panels.
There are either 5 36 extra accumulators or 6 38 missing solar panels.
And slightly over the ratio instead of under is the way to go.
I don t beleve in perfect ratios for solar.
Overall this design has a continuous power rating excluding roboport drain of 8 232mw.
This so sums up factorio perfectionism and practicalism.
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.
More accumulators than needed helps safeguard from unexpected night spikes more solar than can be accumulated gets all wasted.
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.
I leave a space to walk between.
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.
The ideal ratio is 0 84 accumulators panel.
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 and accumulators optimal ratio.
