How does space-based solar power work?

Space-based solar power requires wirelessly transmitting electrical energy across space using microwave or laser power beaming. Unlike laser beams, microwaves can penetrate clouds and rainfall, making them the prime candidate for maximizing solar capacity.

How does solar power work?

The so-called reference design transforms solar power into electricity via photovoltaic cells in geostationary orbit around Earth. The power is then transmitted wirelessly in the form of microwaves at 2.45 GHz to dedicated receiver stations on Earth, called ‘rectennas’, which convert the energy back into electricity and feed it into the local grid.

Can space-based solar power be used on Earth?

Space-based solar power, once a topic for science fiction, is gaining interest. The sun, photographed from the International Space Station about 260 miles above the Pacific Ocean. Wireless power transfer in space is opening the door to harnessing the power of the sun to provide usable power on Earth. NASA

Would a solar power plant in space work?

Unlike solar panels on Earth, a solar power plant in space would provide a constant power supply 24/7. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A first-of-its-kind lab demonstration shows how solar power transmission from space could work.

How does solar power transmission from space work?

Here’s how it works. A first-of-its-kind lab demonstration shows how solar power transmission from space could work. The demonstration, carried out by U.K.-based startup Space Solar, tested a special beaming device that can wirelessly transmit power 360 degrees around.

How much solar power would a satellite generate?

A single solar power satellite of the planned scale would generate around 2 gigawatts of power, equivalent to a conventional nuclear power station, able to power more than one million homes. It would take more than six million solar panels on Earth’s surface to generate the same amount.
