100 W capacity per settler when the sun is shining. This means using anything other than a tablet / smartphone is advised against. Watching television by yourself or with a handful of people should also not be a habit.

1 one MW solar plant will produce +- 0.25 MW average over a 24 hour day.<ref>http://en.wikipedia.org/wiki/PS10_solar_power_plant</ref>
