A large GEO satellite requires a total of 12 kW to operate its communication systems and 1.5 kW for housekeeping purposes. The solar cells on the satellite are mounted on two large sails that rotate to face the sun at all times. The efficiency of the solar cells is 36% at BOL and 33% at EOL. Using an average incident solar flux density of 1.36 kW/m² calculate the area of each solar sail to meet the power requirements at the end of the satellite's life. How much power is generated at BOL? The solar arrays are 2.0 m wide. How long are they?
