Solar panel |
Solar panels are an unlimited source of free energy that produce no pollution. During daylight hours every panel provides the maximum power level, 60kW. Generated power will increase/decrease linearly during dusk and dawn, and no power is produced at night. This means one solar panel produces an average of 42kW over one day and night cycle. The energy gain is different when built on other planets, given their distance from the Sun.
In Factorio: Space Age, the power output of the solar panel varies depending on the location of the planet and whether the solar panel is in space.
Energy management
As already stated, solar panels produce energy only during the day, but you likely want your factory to run at night as well. Accumulators can be charged up with solar panels during the day to power the base at night.
Accumulators are not the only way to work with solar energy. Sometimes it is more economical to just avoid consuming energy at night. For example, if you power a bunch of electric mining drills and electric furnaces to produce iron and copper plates, you could build more drills and furnaces than you actually need, and store the excess metal production during the day. At night you can shut down the drills and furnaces, and let your factory run with the stored plates. Instead of storing energy, you would be storing what the energy is used for. The easiest way to achieve this is by connecting all your extractors and furnaces to an electric network with exactly enough solar panels to make them work during the day, and keeping this network away from your factory's main electric network.
Notes
- A single (normal quality) solar panel outputs an average of 42 kW over a day on Nauvis and requires 0.84672 accumulators to sustain a constant power output through the night (exact numbers, not rounded).
- It takes approximately 23.8 solar panels to operate 1 MW of factory and charge 20.2 accumulators to sustain that 1 MW through the night.
- The optimal ratio for normal quality solar panels to charge enough normal quality accumulators on Nauvis is 2646 accumulators for 3125 solar panels (supplying 42 kW per solar panel).
Optimal Ratios
The optimal ratio of solar panels to accumulators varies depending on the qualities of both the solar panels and accumulators, as well as the planets they're constructed on.

Note that the quality shown in the table is the quality of the solar panels only, and assumes normal accumulator quality. When using accumulators of other qualities, divide the ratio shown by 2/3/4/6 for uncommon/rare/epic/legendary, respectively. All ratios are exact numbers with no rounding.
Space Age
In Space Age, the closer a planet is to the sun, the more power a solar panel on its surface produces. Additionally, as there is no nighttime in space, solar panels on space platforms will generate energy constantly, and at a higher rate than on a planet's surface.
