What angle should a solar panel be tilted to face directly at the sun during equinox at latitude 30?

• A. 15 degrees
• B. 30 degrees
• C. 45 degrees
• D. 60 degrees

Answer: (B)

The correct tilt angle for a solar panel to face directly at the sun during the equinox at a latitude of 30 degrees is 30 degrees. This is because, during the equinoxes, the sun is directly overhead at the equator and its angle of elevation decreases as you move towards the poles. At a latitude of 30 degrees during the equinox, the sun is positioned at an angle that directly corresponds to that latitude above the horizon. By tilting the solar panels at the same angle as the latitude, in this case, 30 degrees, the panels can effectively capture maximum sunlight. This ensures optimal solar energy production during the equinox when the sun crosses the celestial equator. Other angles, such as 15 degrees, 45 degrees, or 60 degrees, would not align the panels properly with the sun's position at that time, leading to less efficient energy capture.
