While the sun is out your solar panels have to output q power where q p.
Factorio solar panel to accumulator ratio.
The amount of solar panels and accumulators you need is more.
When accumulator and solar tech is first obtained i establish the ratio on a blueprint.
Your solar panels have 2 functions.
It takes 23 8 solar panels to operate 1 mw of factory and charge 20 accumulators to sustain that 1 mw through the night.
Then when both of those are met build some more.
Solar panels are producing 0 nominal power 10 of the day.
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.
Alternatively this works out to a ratio of 25 solar panels to 21 accumulators level 2.
If your batteries can t fully charge during the day build more solar.
The ratio doesn t matter nearly as much as people seem to think it does.
Dusk dawn so on average they produce 70 of nominal power.
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.
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.
Night solar panels are producing 50 nominal power 40 of the day.
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.
We would need the fewest accumulators if we would just draw power from them if solar panels would produce no power at all.
Or we can say we need 21 25 0 84 accumulators per solar panel.
So the op post is 100 accurate.
Or we can say we need 25 solar panels per 21 accumulators.
I had found that a ratio of 1 2 to 1 5 accumulators per solar panel worked out perfectly fine.
If they don t last the night build more batteries.
We could do that the other way around.
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.
Provide power p recharge accumulators.
The ratio 100 solar panels to 84 accumulators is optimized for solar panels first than for accumulators.
These are the numbers i use.
Solar panels and accumulators optimal ratio.
Now you have enough for a while.
