2.4 A collector, located in Columbus, Ohio, has a tilt angle of 60° and faces due south. lf the foreground is concrete, find the total solar irradiance on the col-lector at 3:00 pm on january21.

Solution by Steps

step 1

Determine the solar irradiance components: direct, diffuse, and reflected

step 2

Calculate the direct solar irradiance using the tilt angle and time of day

step 3

Calculate the diffuse solar irradiance based on the location and date

step 4

Calculate the reflected solar irradiance from the concrete foreground

step 5

Sum the direct, diffuse, and reflected components to find the total solar irradiance

Answer

The total solar irradiance on the collector at 3:00 pm on January 21 in Columbus, Ohio, with a tilt angle of 60° and facing due south, considering the concrete foreground, is the sum of the direct, diffuse, and reflected components.

Key Concept

Solar Irradiance Calculation

Explanation

The total solar irradiance on a tilted surface is the sum of direct, diffuse, and reflected solar radiation. Each component must be calculated based on the specific conditions such as location, date, time, and surface properties.
