Solar Panel (Subnautica)

Solar Panel Icon

The Solar Panel is a placeable item that absorbs lights and converts it into energy.

It is constructed with the Habitat Builder and can be placed on any surface in any angle, including on the Foundation, except on Seabase modules (but it can be placed on a Room). It can also be damaged and destroyed by striking it with the Survival Knife three times.

A Solar Panel can transfer power up to 20 meters to a Seabase or Power Transmitter. It can store up to 25 energy.

During the day the Solar Panel receives the most sunlight and charges the most. During the evening they decreases in charge since it receives less light as the sun goes down. At midnight there is no charge at all.

Energy Collection Rate

The table below contains the results of testing Solar Panel collection rates. All tests were done at midday. Please note that these are approximate results, and not exact (Sunlight % can vary slightly since the player can only see the percent to the nearest whole number).
