You need 17 solar panels for each steam engine running at max capacity.
Factorio best square solar panel layout.
However high space efficiency is not the best indicator of a good design.
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.
Note your roboports will be closer together here which isn t necessarily a bad thing depending on your base.
This factorio 0 15 workshop covers a solar layout design by zarklord.
Something to consider is that many people like replacing a solar panel with a radar in.
Or more precisely you need power consumption in w 30 kw solar panels.
For each 5 solar panels you need 3 accumulators.
Just add as needed for each.
The ideal ratio is 0 84 accumulators panel.
This layout has 170 accumulators and 196 panels.
Keep in mind that these numbers are approximate you may want to have a buffer for laser turrets if nothing else.
There are either 5 36 extra accumulators or 6 38 missing solar panels.
Solar panels are an unlimited source of free energy that produce no pollution.
Generated power will increase decrease linearly during dusk and dawn and no power is produced at night.
This so sums up factorio perfectionism and practicalism.
It has 0 84 accumulator panel ratio which is as close as you can get with a perfect square shaped design with proper power lines.
I leave a space to walk between.
I don t beleve in perfect ratios for solar.
Plop a sub station down and fill it with solar pannels.
I almost always exclusively use cilya s design on all of my playthrough s and i still couldn t find a better setup for solar panels after all this time.
Solar panels and accumulators optimal ratio.
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.
This means one solar panel produces an average of 42 kw over one day and night cycle.
Overall this design has a continuous power rating excluding roboport drain of 8 232mw.
During daylight hours every panel provides the maximum power level 60kw.
The build has the perfect ratio of solar panels to accumulators is nearly symmetrical and tilable.
