Q4. Figure 1 shows the sun's path at different times of the year A, B and C. The sun is on the middle path at A, upper path at time B and lower path at C. SUMMER SOLAR SUN PATH WINDOW WINTER SUN PATH -EQUINOX SUN PATH LARGER TILT ANGLE TILT ANGLE CLOSE TO LATITUDE SMALLER TILT ANGLE A B с Figure 1: Variation of the sun's path across the sky for different times of a year (A, B, C) a) Referring to Figure 1, briefly explain why the tilt angle for a solar collector should be changed as the time of the year changes across the times A to C. Also, explain how the tilt angles compare to each other for the different times. b) Determine the sunrise time and duration of a day for a location 18°S latitude and 31°E longitude on 15 June and 15 October |
