Question

On Earth, sunlight has intensity 1370 W/m². You can assume the distance from theSun to the Earth remains constant over time. a. Calculate the maximum value of the electric field at this intensity. b. Calculate the maximum value of the magnetic field at this intensity. c. Solar panels with an efficiency of 20%, convert 20% of the power in solar radiation into electrical power when the sun is overhead. A household requires 3 kW of power from a rooftop solar array when the sun is overhead. Calculate the area of the solar panels. d. Given the Sun's distance, 1.5×10¹¹ m from Earth, and assuming it radiates power equally in all directions, calculate the total power of the Sun. e. Mars orbits the Sun at a distance of 2.3×10¹¹ m. Calculate the intensity of sunlight on Mars. f. Calculate the maximum power generated by a 1.0 m² solar array on Mars when the Sun is overhead, assuming an efficiency of 20%. (I.e. 20% of the intensity of the light is converted to useful electrical power.)
