Question

A rectangular selar panel has dimensions of 3 m x 4 m. On an average daylight, the intensity of sunlight is about 1 kW/m2. Assume that the panel absorbs all of the Incident sunlight, but it converts the electromagnetic energy into electrical energy with an efficiency of 25 %. Take the speed of light as c = 3 Times 108 m/s, the permittivity of free space as epsilon0 = 9 times l0-12 C2/ (N.m2) and assume that the incident light is perpendicular to the surface of the solar panel. Find the average power of electricity generated by the solar panel. Find the total electric energy generated in 10 hours? What is the average force exerted on the solar panel, due to the incident light? What is the amplitude of the electric field, E m, of the incoming sunlight?
