• This source of power is very large and very heavy, so it is only appropriate for large satellites
• A parabolic dish of mirrors reflects the heat of the sun through a boiler and then through a generator which converts the solar power into electricity
• This type of power is completely renewable and efficient if the satellite will be in the sun
• It could be used in conjunction with batteries
• This source of power is currently in the testing phase
• NASA is experimenting with using this source of power for the International Space Station
