32. Electromagnetic Waves / Intensity of EM Waves / Problem 3
An agricultural facility in a rural area relies on solar power for its operations. On clear days, the sunlight intensity is 1050 W/m², and the solar panels used have an efficiency of 22%. Calculate the area 𝐴 of solar panels required to power (i) a large water distribution system that consumes 90 hp. (ii) If the facility's roof has an available area of 240 m², determine whether it is practical to install the required solar panels on the roof.
