We would need the fewest accumulators if we would just draw power from them if solar panels would produce no power at all.
Accumulators solar panel ratio.
And each cycle the accumulator charge goes from 0 to 100 and back to 0.
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.
We could do that the other way around.
100 solar panels to 84 accumulators.
Or we can say we need 25 solar panels per 21 accumulators.
I tried it out in sandbox mode with krastorio 2 and it seems correct.
If they don t last the night build more batteries.
Or we can say we need 21 25 0 84 accumulators per solar panel.
20 regular solar panels or 8 advanced solar panels combined with 14 20 0 7 accumulators gave a stable 1 4mw for 35 sentinels 35 20kw 1 4mw.
So the op post is 100 accurate.
500 21 p mw solar panels 20 p mw accumulators these are the numbers i use.
The ratio 100 solar panels to 84 accumulators is optimized for solar panels first than for accumulators.
The ratio doesn t matter nearly as much as people seem to think it does.
One of the biggest improvement of this design is the efficient use of space and substations.
Then when both of those are met build some more.
If your batteries can t fully charge during the day build more solar.
That s the ratio most people on the forums use and used for a long time works pretty well for me as well.
Alternatively this works out to a ratio of 25 solar panels to 21 accumulators.
164 solar panel 141 accumulators which gives an ratio of 0 86 a bit higher than the optimal but in my opinion just perfect.
If anybody has some suggestions to make this design even better please let me know.
The amount of solar panels and accumulators you need is more.
Either network can charge the accumulators and the accumulators can discharge into either network.
600 mj capacity of accumulators.
Now you have enough for a while.
So for 2 1mw this works out to 50 solar panels and 42 accumulators exactly.
Note that this isolation is bidirectional.
