1. What is the Solar Panel Angle Calculator?

The Solar Panel Angle Calculator determines the optimal tilt angle for solar panels based on your location's latitude and the current season. Proper panel orientation maximizes solar energy capture throughout the year.

2. How Does the Calculator Work?

The calculator uses these simple formulas:

Where:

• \( latitude \) — Your geographic latitude in degrees (positive for north, negative for south)
• \( 15° \) — Seasonal adjustment factor

Explanation: The formulas account for the sun's changing position in the sky between seasons, with summer sun being higher and winter sun being lower.

3. Importance of Optimal Tilt Angle

Details: Proper panel tilt can increase energy production by 10-25% compared to flat installation. The ideal angle varies by location and season to maximize sun exposure.

4. Using the Calculator

Tips: Enter your latitude (find it using GPS or online maps), select the current season. Latitude must be between -90° and 90°.

5. Frequently Asked Questions (FAQ)

Q1: What about spring and fall angles?
A: For spring/fall, use your latitude exactly (no seasonal adjustment). This calculator focuses on seasonal extremes.

Q2: Should I adjust my panels monthly?
A: While monthly adjustments are ideal, most homeowners adjust seasonally (2-4 times per year) for practical reasons.

Q3: What if my roof angle is fixed?
A: If you can't adjust, choose an angle between your summer and winter angles (often equal to your latitude).

Q4: Does this work for both hemispheres?
A: Yes, use positive latitude for northern hemisphere, negative for southern hemisphere.

Q5: Are there more precise calculation methods?
A: Yes, advanced methods consider daily sun paths, but this simple rule works well for most residential installations.
