It takes 23 8 solar panels to operate 1 mw of factory and charge 20 accumulators to sustain that 1 mw through the night.
Factorio solar panels to accumulators ratio.
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.
Or we can say we need 25 solar panels per 21 accumulators.
Without detailed calculations i believe that solar panels cost more than accumulators.
Every ratio from almost 0 to infinite is valid as long as you have enough panels acc.
If they don t last the night build more batteries.
A close enough ratio is 20 24 1 accumulators to solar panels to megawatts required for example a factory requiring 10 mw can be approximately.
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.
Or we can say we need 21 25 0 84 accumulators per solar panel.
And each cycle the accumulator charge goes from 0 to 100 and back to 0.
If your batteries can t fully charge during the day build more solar.
The amount of solar panels and accumulators you need is more.
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.
A single solar panel outputs an average of 42 kw over a day and requires 0 84 accumulators to sustain a constant power output through the night.
The ratio doesn t matter nearly as much as people seem to think it does.
Then when both of those are met build some more.
8571 3 7 kw solar panels 600 mj capacity of accumulators so the result is we need 25 21 1 190476 period 6 more solar panels than accumulators.
So the op post is 100 accurate.
Your factory needs an average p power.
Since you need more you can not round down so roughly 92 or 92 accumulators per 100 solar panels 23 25 or 46 50 or inversely you get roughly 1 091325249022011 solar panels per accumulator this change means in the long run you need less solar per accumulator.
I tried it out in sandbox mode with krastorio 2 and it seems correct.
