- Solar Reflectors – The orientation of the satellites is sun pointing to constantly reflect sunlight onto the solar panel array below.
- Solar Panels and Transmitters – 60,000 layers of power modules collect the sunlight from the reflectors and convert this to high-frequency radio waves.
- Power Transmission – A coherent, collimated beam of radio waves is transmitted to a rectifying antenna on the ground.
The ‘rectenna’ is a large but sparse net-like structure holding the small dipoles which convert the microwave energy into electricity.
It is typically several kilometres in diameter, though the area is just 8% of a wind farm delivering equivalent energy output, and could be sited offshore adjacent to wind farms.
CASSIOPeiA – the market leading Solar Power Satellite design
Of the Solar Power Satellite concepts which can deliver 24/7 baseload power, the most capable is CASSIOPeiA. Conceived by the UK company IECL it has patented design features which offer strong economic and operational benefits, with a best-in-class specific power predicted to be 1 kW/kg.
This results in a low Levelised Cost of Electricity competitive with intermittent terrestrial renewables.
