Seamoth Solar Charger

The Seamoth Solar Charger is an in-development Upgrade Module that enables the player to recharge their Seamoth's battery while in the sun.

Currently, applying the Seamoth Solar Charger to a Seamoth gives it unlimited Energy during the day and the night. This is expected to change in the future.

Speculation
It is to be assumed that the efficiency of this Upgrade Module will decrease the further the Seamoth is away from the water surface, similar to the Solar Panel.
