Question:
Solar panels are often used on spacecraft to provide power. Calculate the amount of power generated by the solar panels near Earth, Mars, and Saturn. Also calculate the temperature of the spacecraft at these locations. The efficiency of the solar panels is \(20 \%\). The intensity of sunlight at Earth's surface is \(1350 \mathrm{~W} / \mathrm{m}^{2} \mathrm{~K}\). The distances of the Earth, Mars, and Saturn from the Sun is \(149.6 \times 10^{6} \mathrm{~km}, 227.9 \times 10^{6} \mathrm{~km}\), and \(1427 \times 10^{6} \mathrm{~km}\). The solar panels have an area of \(10 \mathrm{~m}^{2}\). The body of the spacecraft is a cylinder of length \(3 \mathrm{~m}\) and diameter \(2 \mathrm{~m}\). The body absorbs \(80 \%\) of incident light and the panels absorb \(70 \%\) but can convert all that absorbed power into electricity.
