Question

A solar energy system has a number of collectors in parallel facing southwest in (42 degree N, 83 degree w) as shown. The lilt angle of collectors from the ground is same as the Dearborn. Find the angle of incidence on the collector at solar noon on Summer Solstice (Jun 21^st). Re-do part a) if the collectors are facing south. find the beam component of the incident radiation on the collector, l_b, c (It can be found from the table that for Dearborn Ml. tau_b = 0.519, tau_d = 1.784, b = 0.738, d = 0.301)

Explanation / Answer

A solar energy system has a number of collectors in parallel facing southwest in Dearborn (42° N, 83° W) as shown. The tilt angle of collectors from the ground is same as the latitude Dearborn.

The summer Solstice occurs on June 21st when solar declination is 23.5° which is a maximum

Actually of the collectors are facing the incidence of solar energy on solar panel is less than when it face west or southwest.

(It can be found from the table that Dearborn MI

Tb=0.519, td=1.784, b=0.738, d=0.301)
