The small and medium solar panels you can craft in your Backpack (left) and on the Printer (right).
Solar Panels are power production items that produce consistent power when exposed directly to sunlight. Power outputs vary depending on which solar device is being used and the planet that it is being used on.
Small Solar Panel
A Small Solar Panel on the left widget slot of the backpack, oriented toward the sun.
Small solar panels are crafted in your backpack's printer, using Copper. This kind of panel can be placed on any item slot, but in the backpack, it will only produce power when placed on one of the widget slots (see image on the right).
When exposed to light, the panel will orient itself automatically toward the sun (if possible) and produce 0.5U/s of power, or enough to fill one bar on a Small Battery in 8 seconds.
Medium Solar Panel
Medium Solar Panels are crafted in the Small Printer module, using 1 piece of Copper and 1 piece of Glass. They can be placed on any Tier-2 slot.
When exposed to sunlight, a Medium Solar Panel produces power at 2U/s, which is exactly four times as much as a Small Solar.
Solar Array
A Solar Array, plugged in and providing power. Points in the direction of the sun.
The Solar Array is the largest craftable solar panel, being made in the large printer. They can be crafted using 1 Copper, 1 Glass, 1 Plastic, and 1 Graphene. This is the only solar unit that acts as a platform, meaning that it must be placed on the ground.
When exposed to sunlight, the Solar Array produces 8U/s of power, which is sixteen times more than a Small Solar Panel and four times more than a Medium Solar Panel.
Wrecked Solar Array
A Wrecked Solar Array lodged inside of a mountain on Sylva.
The Wrecked Solar Array is the only non-craftable solar panel, found naturally as debris on all planets. When plugged in and exposed to sunlight, the Wrecked Solar Array provides 2U/s to 4U/s of power varying dynamically depending on the angle of sunlight relative to the panel. They only have panels on one side, and must be placed with the connection point facing upwards to work.
Sun Effectiveness
Each planet has its own Sun effectiveness, which affects the power produced by the solar panels.
