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.
Factorio solar panel to accumulator ratio.
Solar panels are producing 0 nominal power 10 of the day.
Or we can say we need 25 solar panels per 21 accumulators.
The ratio 100 solar panels to 84 accumulators is optimized for solar panels first than for accumulators.
The amount of solar panels and accumulators you need is more.
Alternatively this works out to a ratio of 25 solar panels to 21 accumulators level 2.
For me it is 1 1 mainly because of the spatial design easily tile able and low supply for the slow conbots out of the mk1 personal roboport not because of any other reason.
When accumulator and solar tech is first obtained i establish the ratio on a blueprint.
Or we can say we need 21 25 0 84 accumulators per solar panel.
Solar panels and accumulators optimal ratio.
Then when both of those are met build some more.
We could do that the other way around.
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.
Night solar panels are producing 50 nominal power 40 of the day.
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.
It takes 23 8 solar panels to operate 1 mw of factory and charge 20 accumulators to sustain that 1 mw through the night.
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.
Now you have enough for a while.
Dusk dawn so on average they produce 70 of nominal power.
I had found that a ratio of 1 2 to 1 5 accumulators per solar panel worked out perfectly fine.
Provide power p recharge accumulators.
These are the numbers i use.
So the op post is 100 accurate.
So for 2 1mw this works out to 50 solar panels and 42 accumulators exactly.
If your batteries can t fully charge during the day build more solar.
While the sun is out your solar panels have to output q power where q p.
If they don t last the night build more batteries.
The ratio doesn t matter nearly as much as people seem to think it does.
500 21 p mw solar panels 20 p mw accumulators.
