Solar panels are an unlimited source of free energy that produce no pollution.
Factorio best solar panel layout.
Note your roboports will be closer together here which isn t necessarily a bad thing depending on your base.
This means one solar panel produces an average of 42 kw over one day and night cycle.
You need 17 solar panels for each steam engine running at max capacity.
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.
Haven t seen this design posted anywhere so here is yet another 0 15 solar panel layout this solar panel layout has a roboport only uses 4 substations has the exact 0 84 ratio 84 accumulators 100 solar panels and is symettrical.
I don t beleve in perfect ratios for solar.
Just add as needed for each.
Though in all honesty you probably aren t ready for solar panels yet if the cost bothers you.
Also there are more capacitors than panels because capacitors are far more important.
Overall this design has a continuous power rating excluding roboport drain of 8 232mw.
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.
During daylight hours every panel provides the maximum power level 60kw.
I ve got two rings of solar panels 7 accumulators and a big powerpole in the innermost ring with the substation in the middle of course.
Keep in mind that these numbers are approximate you may want to have a buffer for laser turrets if nothing else.
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.
There are either 5 36 extra accumulators or 6 38 missing solar panels.
Or more precisely you need power consumption in w 30 kw solar panels.
The ideal ratio is 0 84 accumulators panel.
Generated power will increase decrease linearly during dusk and dawn and no power is produced at night.
For each 5 solar panels you need 3 accumulators.
I almost always try to stick a layout similar to the picture sbroadbent posted.
This layout has 170 accumulators and 196 panels.
I leave a space to walk between.
Solar panels and accumulators optimal ratio.
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.
Personally i prefer a more solar panel leaning ratio for my power clusters.
