A homeowner is planning to install solar panels on their roof. They live in the Northern Hemisphere and want to maximize the energy output of the panels throughout the year. In which direction should the solar panels primarily face?
- ANorth
- BSouth
- CWest
- DEast
Show answer & explanationAnswer & explanation
Correct answer: B. South
In the Northern Hemisphere, the sun's path is always in the southern sky. To maximize solar energy capture, panels should face south to receive direct sunlight for the longest duration throughout the day and year.
Why the other options are wrong
- A. Facing north in the Northern Hemisphere would result in minimal direct sunlight exposure.
- C. Facing west would capture afternoon sun but miss significant morning sun.
- D. Facing east would capture morning sun but miss significant afternoon sun.
Solar Panel Orientation (Northern Hemisphere)
To maximize energy capture in the Northern Hemisphere, solar panels should primarily face south to receive the most direct sunlight throughout the day and year.
- Sun's path is in the southern sky in the Northern Hemisphere
- Direct sunlight is most efficient for energy generation
- Adjustments for specific seasons or peak times may be made
Memory trick: North is where the sun is NOT, South is where the sun is HOT!
