Actually, I have an exam after the next 3 hours and now, after watching this video I am feeling like I have already completed the whole course successfully. Thank You for the brief and clear explanation in a short period of time.
This means that in your example your chosen latitude is 15⁰N at the equinox? (The sun rising and setting due east and west but at 75⁰ above the horizon at 180⁰S - 15⁰ north of the equator)
After I reviewed the video, I did not seem to get when to use the intersecting point whether to use the right or the left @4:00? Any further explanation?
if you have a two-axis tracker located at 44 degrees N, at what time and date is the collector azimuth angle equal to 30 degree and the tilt angle equal to 70 degrees?. Thank you
