Continuing our series on unique power stations crossing new frontiers, the International Space Station is powered by 9,600 sq.ft, 892 sq.m. of solar arrays. This large array provides electricity at 160 V. Batteries are needed to store electricity for powering life support systems when the station is shielded from the sun. Through the combined PV-battery system, 78 kW power is continuously available in the station.
