1. What is a Solar Panel Pitch Calculator?

Definition: This calculator estimates the optimal tilt angle for solar panels based on your location's latitude and seasonal requirements.

Purpose: It helps homeowners and installers maximize solar energy collection by determining the best panel orientation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Tilt \) — Optimal solar panel angle (degrees)
• \( Latitude \) — Your geographic latitude (degrees)
• \( \pm 15° \) — Seasonal adjustment (summer/winter)

Explanation: The base angle equals your latitude, adjusted ±15° for seasonal optimization.

3. Importance of Proper Solar Panel Tilt

Details: Correct tilt angle maximizes energy production, improves system efficiency, and optimizes return on investment.

4. Using the Calculator

Tips: Enter your location's latitude (positive for north, negative for south) and select seasonal preference.

5. Frequently Asked Questions (FAQ)

Q1: Why does the angle change with seasons?
A: The sun's path changes seasonally; winter sun is lower, requiring steeper angles for optimal capture.

Q2: What's the best angle for year-round production?
A: Setting panels at your latitude (annual average) provides good year-round performance with minimal adjustment.

Q3: How precise does the angle need to be?
A: Within 5° of optimal is generally acceptable; exact precision isn't critical for most residential systems.

Q4: Should I adjust my panels seasonally?
A: Adjustable mounts can increase production by 5-15%, but fixed mounts at latitude are simpler and still effective.

Q5: What if my roof pitch doesn't match the ideal angle?
A: Within 30° of optimal is usually fine; production loss is minimal for small deviations.
