I had found that a ratio of 1 2 to 1 5 accumulators per solar panel worked out perfectly fine.
Factorio solar panel accumulator ratio.
Anyway here s the source.
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.
Since the maximum input output rate of an accumulator is 300 kw power flow between the two networks will be limited to 300 kw times the number of accumulators 1 5 mw in the example.
Note that this isolation is bidirectional.
Just divide if you need a decimal.
The ratios posted result in more solar panels then are needed to power factory and charge accumulators i had posted this in a topic on the steam forum a week ago when somebody was asking about solar panels and another person brought up the 0 8 1 ratio.
When accumulator and solar tech is first obtained i establish the ratio on a blueprint.
The ratio 100 solar panels to 84 accumulators is optimized for solar panels first than for accumulators.
We could do that the other way around.
We could do that the other way around.
We would need the fewest accumulators if we would just draw power from them if solar panels would produce no power at all.
So the op post is 100 accurate.
Reverse operation ratio from decimal needs multiplication and reduction by the largest common divisor.
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.
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.
Either network can charge the accumulators and the accumulators can discharge into either network.
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.
It takes 23 8 solar panels to operate 1 mw of factory and charge 20 accumulators to sustain that 1 mw through the night.
