At a location, the average yearly solar irradiance is 4.5-kWh/day. Estimate the yearly electric energy generation of an array with the inclination equal to the latitude and total power capacity of 10 kW.

At a location with latitude 40∘ north, solar irradiance is 800-W/m2 at a certain time on a horizontal surface with 180∘ azimuth. Determine the irradiance on a 30∘ inclined surface with 160∘ azimuth.
