The international space station, orbiting the earth, is powered by 8 solar "wings" that rotate so that they always face perpendicular to the sun's incident radiation. Each wing is 35m long and 12m wide and 15.6% of the area is covered by silicon (Si) solar cells. The solar cells have emissivity esi = 0.65, and reflection coefficient, which is 0.3. The solar wings are thin, ie. the edge area is very small compared to the face area. The solar cells are 18% efficient at converting light to electrical power. The incident intensity of the sun at the distance of the earth is 1367 W/m2. the same as albedo, Ri = a) How much power is produced by the station when the panels are exposed to the sun (ie. not when the station is shadowed by the earth)? b) What temperature do the solar cells reach when they are exposed to the sun (ie. not shadowed by the earth)? solar wings
