Factorio Solar Panel Rates

A huge thanks to to all the contributors on github as well as the community who made the previous cheat sheets and other resources.

Factorio solar panel rates.

Solar panels and accumulators optimal ratio. How many solar panels does it take to charge an accumulator in 1 day. The night time set would have the accumulators. The minimal ratio of accumulators to solar panels is 0 84 any less and it will not store enough for the night so the minimum to keep the radar running at all times is.

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. The radar will be attacked by enemies that come within very close range like turrets due to its status as a military building but will not attract. However you need an additional buffer in order to recharge your accumulators. At maximum the solar panel will output 60 kw but throught the whole day it will avarege to 0 7 that value 42 kw.

This means one solar panel produces an average of 42 kw over one day and night cycle. Such as the wiki reddit and factorio discord from which this is all based on. Radar consumes 300kw which is 5 solar panels at it s full. Solar panels are an unlimited source of free energy that produce no pollution.

Generated power will increase decrease linearly during dusk and dawn and no power is produced at night. Portable solar panels are the basic power generating units for modular armor and the spidertron they provide only a small amount of power and only during the daytime. So each solar panel yields 42 kw on average 70 of 60 kw. 5mj of stored energy takes approximately 17s to fully charge discharge at the maximum rate of 300kw.

Read time seconds for further time related calculations. It gives the radar full power all but a short time in the morning but never dips below the 20 power threshold for nearby scanning. Factorio is a game in which you build and maintain factories. I am new to factorio.

Portable solar panels can be used to slowly recharge energy shields out of combat but are nearly useless for personal laser defense or exoskeleton even with a large number of batteries. 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. So you could divide your total power need by 42 kw to figure out how many solar panels you need. Seven solar panels and five accumulators is the most efficient.

Each solar panel is useful for 70 of the time. It takes 20 accumulators 100mj to maintain 1mw through the night because the accumulators don t immediately start discharging at the beginning of dusk see the graph in this post. This is a compendium of the most common factorio facts as of v1 0 release.
