A student calculates an optimal tilt angle of 45 degrees, for a given location. For this calculation, the student only considered direct beam irradiation and ignored the effects of the atmosphere. Whilst still ignoring clouds, how do you expect the optimal tilt angle will change if you take into account the influence of the atmosphere?
A)The optimal tilt angle will increase. This is due to a higher energy yield, caused by an increased sky view factor.
B)The optimal tilt angle will increase. This is because at lower sun altitudes, the atmosphere absorbs more light compared to higher altitudes.
C)The optimal tilt angle will decrease. This is due to a higher energy yield, caused by an decreased sky view factor.
D)The optimal tilt angle will decrease. This is because at lower sun altitudes, the atmosphere absorbs more light compared to higher altitudes.

My guess would be B. As the atmosphere gets hazy, the less of it the rays pass through the better.
