1. What is Solar Panel Azimuth?

Solar panel azimuth refers to the compass direction that the panels face. In the UK, the optimal azimuth for maximum solar energy production is due south (180°), as this orientation captures the most sunlight throughout the day.

2. How Does the Calculator Work?

The calculator determines the optimal azimuth for solar panels in the UK:

Where:

• 180° — Due south direction (optimal for UK)

Explanation: For locations in the UK, south-facing orientation provides the best year-round solar exposure and energy production.

3. Importance of Optimal Azimuth

Details: Proper azimuth alignment is crucial for maximizing solar energy production, improving system efficiency, and optimizing return on investment for solar installations.

4. Using the Calculator

Tips: Enter your current azimuth measurement (if available) to see how much it deviates from the optimal south-facing position. The calculator will show both the optimal azimuth and any deviation from it.

5. Frequently Asked Questions (FAQ)

Q1: Why is south-facing optimal in the UK?
A: The UK is in the northern hemisphere, so south-facing panels receive the most direct sunlight throughout the day and across seasons.

Q2: Can other azimuths work for solar panels?
A: While south-facing is optimal, southeast (135°) or southwest (225°) orientations can still provide good energy production, typically around 90-95% of optimal.

Q3: How much does azimuth affect energy production?
A: Deviation from south can reduce energy production by 5-15% for every 45 degrees of misalignment, depending on location and season.

Q4: Should roof pitch be considered with azimuth?
A: Yes, both azimuth and tilt angle work together to optimize solar capture. The ideal tilt for UK is typically 30-40 degrees.

Q5: Are there exceptions to the south-facing rule?
A: In some cases, west-facing panels might be preferred to shift production to afternoon hours when electricity demand is higher.
