Circuitboard (Solar Control)
From Unofficial Stationeers Wiki
Solar control lets you remotely control the angle of any Solar Panel connected to it.
Solar control needs to be installed in a Console and connected to the network input of the Solar Panels you wish to control. You'll need to use a Data Disk to tell the Solar Controller which Solar Panels you want to control.
The Solar control Circuitboard provides no means of automation and requires a player to adjust its setting trough the day to maintain the maximum power output as the Sun moves on the sky. Because of that it is rarely used. For only one panel the same job could be done with a wrench.
