500 21 p mw solar panels 20 p mw accumulators.
Factorio solar panel to accumulator ratio.
Now you have enough for a while.
The ratio doesn t matter nearly as much as people seem to think it does.
The ratio 100 solar panels to 84 accumulators is optimized for solar panels first than for accumulators.
If your batteries can t fully charge during the day build more solar.
I had found that a ratio of 1 2 to 1 5 accumulators per solar panel worked out perfectly fine.
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.
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.
Then when both of those are met build some more.
Dusk dawn so on average they produce 70 of nominal power.
Solar panels are producing 0 nominal power 10 of the day.
It takes 23 8 solar panels to operate 1 mw of factory and charge 20 accumulators to sustain that 1 mw through the night.
Provide power p recharge accumulators.
While the sun is out your solar panels have to output q power where q p.
We could do that the other way around.
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.
The amount of solar panels and accumulators you need is more.
So for 2 1mw this works out to 50 solar panels and 42 accumulators exactly.
Or we can say we need 21 25 0 84 accumulators per solar panel.
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.
Or we can say we need 25 solar panels per 21 accumulators.
Your solar panels have 2 functions.
Solar panels and accumulators optimal ratio.
If they don t last the night build more batteries.
So the op post is 100 accurate.
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.
We would need the fewest accumulators if we would just draw power from them if solar panels would produce no power at all.
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.
Alternatively this works out to a ratio of 25 solar panels to 21 accumulators level 2.
