South Korea s 120kW Solar Energy Storage Container

How much solar power will Korea's space solar power satellite provide?

Two Korean research institutes are designing the 2.2 km × 2.7 km Korean Space Solar Power Satellite project with the aim of providing approximately 1 TWh of electricity to the Earth per year. The proposed system should use 4,000 sub-solar arrays of 10 m × 270 m, made out of thin film roll-out, with a system power efficiency of 13.5%.

How many sub-solar arrays will Korea use?

It will use 4,000 sub-solar arrays of 10 m × 270 m, made out of thin film roll-out, with a system power efficiency of 13.5%. On the ground, the researchers propose to place 60 rectennas with a diameter of 4 km along the Korean Demilitarized Zone (DMZ).

How much electricity does South Korea use in 2021?

“This amount exceeds South Korea’s electricity consumption in 2021 (0.5334 TWh) and surpasses the combined electricity consumption of South and North Korea for a certain period of time.” Based on previous literature, with a lifetime of 30 years, such a structure could provide electricity at a price of $0.03/kWh.
