Aspacecraft orbiting earth relies on solar panels that have an efficiency of 26% (percent of incoming energy the panels can convert) for power. the spacecraft has a battery to store energy for the half of isorbi the spacecraft is on the night side of the planet and incoming solar irradiance is 1367 w/m2. how big do the panels have to be at minimum if the spacecraft require 1000 w of power? show your work.
