Description
1. a) Solar radiation at the Earth’s surface consists of three primary components.
i. What are these three components?
ii. On a clear day, which one of these components is responsible
for the blue colour of the sky?
b) A client from Granada (Lat. 37.18°N, Long. 3.59°W) is looking for advice for installing a photovoltaic array.
i. If the global horizontal irradiance is 643 W/m2 on the 7th of October (DoY 280) at 3pm (15:00) solar time, calculate the total irradiance incident on a South-facing plane at a tilt angle of 48.5°. [8 marks]
ii. Explain how you could expand this calculation to identify the collector tilt angle which would give the maximum yearly average yield.
iii. In addition to the longitude and latitude, what other information
about the geographical location of the site might you need in
order to carry out a more comprehensive analysis?
