There is a lot of talk today about the best, most efficient and greenest way to produce energy. Clearly, using the power of the sun is always one of the most preferred methods, especially if one lives in a place with lots of sunlight. But what about Factorio, can we efficiently use this resource to power our factory? Let us try to do our best and discover the best Factorio solar panel ratio.

Clearly, there is no overall perfect way to plan ahead for the production of electrical energy and you might want to start working towards using green methods, thus reducing pollution, as soon as you’re able. But this might vary from game to game, so do not hurry too much towards solar energy or you might find yourself in trouble, early on especially.

With that said, let us delve into the ideal Factorio solar panel ratio for your average run.

What is the best solar panel ratio?

Calculating all different factors in the game, we can average the solar panel ratio to be 0.84 accumulators per solar panel. Overall your factory will require 23.8 solar panels per megawatt, so you can quickly calculate how many should you need to set up.

For example, if your factory requires 20 MW of power to run, you can easily calculate that you’ll need 476 solar panels and, in turn, almost 400 accumulators. Clearly, the more solar panels one adds, the more efficiency you’ll lose in the long run, so you might want to make sure you’re always producing enough energy to keep production running.

We hope this guide is helpful in planning ahead your solar power production, should you need more starting tips be sure to check out our beginner’s guide. If you’re really stuck and desperate, perhaps you might also want to check out the best Factorio cheats.
