Solar cells

Solar cells are small satellites that stay in your planet's orbit and turn sunlight into energy for mines and other buildings. They do not take up any building fields.

Depending on the sunlight, one cell delivers 10 to 60 energy: planets close to their sun get the most out of them, distant ones much less.

Strengths and weaknesses

• + Available from weapons factory level 1 and quick to build.
• + No building fields and easy to expand – if you run short of energy, just build more.
• – Solar cells count as defense: when you are attacked, they take part in the battle and can be destroyed without firing a shot. The Particle cannon can hit them too, but only as its very last target.
