Diffuse solar radiation given total solar energy and direct radiation Solution

Follow our step by step solution on how to calculate Diffuse solar radiation given total solar energy and direct radiation?

FIRST Step Consider the formula

G d = G solar - G D \cdot \cos (i)

Next Step Substitute values of Variables

∴

G d = 950W/m² - 800W/m² \cdot \cos (40°)

Next Step Convert Units

∴

G d = 950W/m² - 800W/m² \cdot \cos (0.6981rad)

Next Step Prepare to Evaluate

∴

G d = 950 - 800 \cdot \cos (0.6981)

Next Step Evaluate

∴

G d = 337.16444550475W/m²

LAST Step Rounding Answer

∴

G d = 337.1644W/m²
