Question 1.
What does GHI stand for?
Show hintHide hint
Think about the total sunlight on a flat surface.
Question 2.
What is the key factor in solar panel tilt angle?
Show hintHide hint
Consider how panels should be positioned for optimal energy capture.
3Question 3.
What does GHI measure?
- Direct sunlight
- Total sunlight on a horizontal surface
- Only reflected sunlight
Show hintHide hint
Think about how much energy a horizontal panel can capture.
4Question 4.
True or False: The tilt angle of a solar panel is irrelevant for energy capture.
- True
- False
Show hintHide hint
Consider the physics of sunlight hitting an angle.
Question 5.
Given a location at 35° latitude, determine the most effective tilt angle for solar panels if you aim for maximum annual energy collection.
Show hintHide hint
Use latitude as a base reference for adjusting the angle.
Question 6.
Describe how changing the orientation of solar panels from the east to the west at a specific tilt impacts energy capture throughout the day.
Show hintHide hint
Consider the sun's path across the sky.
