Here is a quite popular blueprintable design by madzuri.
Best solar panel setup factorio.
Plop a sub station down and fill it with solar pannels.
Just add as needed for each.
I don t beleve in perfect ratios for solar.
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.
This layout has 170 accumulators and 196 panels.
The ideal ratio is 0 84 accumulators panel.
This so sums up factorio perfectionism and practicalism.
Though in all honesty you probably aren t ready for solar panels yet if the cost bothers you.
For each 5 solar panels you need 3 accumulators.
You need 17 solar panels for each steam engine running at max capacity.
Mk1 a mark one is just a bunch of poles with y know solar panels mixed in madzuri nov 2016 mk2 focuses on ratios mk3 uses roboports to construct the tile mk4 uses a diagonal spacing to reduce roboports and ups mk5 makes use of most if not all of the radar range.
Generated power will increase decrease linearly during dusk and dawn and no power is produced at night.
Or more precisely you need power consumption in w 30 kw solar panels.
You can always sacrifice a bit of the optimal ratio for a cleaner design but you should stay in the area of 0 8 0 9.
The optimal ratio is 0 84 thus a more ideal setup would be 21 accumulators to 25 solar panels.
Keep in mind that these numbers are approximate you may want to have a buffer for laser turrets if nothing else.
Overall this design has a continuous power rating excluding roboport drain of 8 232mw.
I leave a space to walk between.
There are either 5 36 extra accumulators or 6 38 missing solar panels.
Solar panels and accumulators optimal ratio.
During daylight hours every panel provides the maximum power level 60kw.
2628 accumulators 3118 solar panels 0 8428.
