Tilt Angle
Tilt angle refers to how much solar panels are sloped to capture the most sunlight possible. It's like positioning an umbrella to get the best shade - solar installers need to find the perfect angle to help solar panels produce the most energy. This angle changes based on where the building is located on Earth and sometimes needs to be adjusted during different seasons. When reviewing resumes, you might see it mentioned as "solar panel tilt," "array tilt," or "optimal angle" - these all mean the same thing. It's a crucial skill for solar installers and designers to understand, as it directly affects how much power a solar system can generate.

Example Interview Questions
Senior Level Questions
Q: How would you determine the optimal tilt angle for a large commercial solar installation in different seasons?
Expected Answer: A senior candidate should explain how latitude affects tilt angle, seasonal adjustments, and mention tools or software used for calculations. They should also discuss factors like weather patterns and site-specific constraints.
Q: How do you train teams to properly implement tilt angle calculations in the field?
Expected Answer: Look for answers that show leadership experience, ability to simplify complex concepts, and practical knowledge of installation challenges and safety considerations.
Mid Level Questions
Q: What factors affect the choice of tilt angle for a residential solar installation?
Expected Answer: Candidate should mention location latitude, roof pitch, seasonal changes, and local weather patterns. They should also discuss how these factors influence energy production.
Q: How do you calculate energy loss from a non-optimal tilt angle?
Expected Answer: Look for understanding of basic solar calculations, ability to use solar design software, and knowledge of how angle variations impact system performance.
Junior Level Questions
Q: What is the general rule of thumb for tilt angle in relation to latitude?
Expected Answer: Should know that tilt angle typically equals the location's latitude for optimal year-round performance, and understand this is a starting point for more detailed calculations.
Q: What tools do you use to measure tilt angle during installation?
Expected Answer: Should be familiar with basic tools like inclinometers, digital angle finders, and smartphone apps used for measuring panel tilt.
