Panel Pitch, Orientation, and Location: A Detailed Insight into Solar Efficiency in New Zealand

The pitch of your solar panels, corresponding with their vertical tilt, is crucial in energy efficiency. In Auckland, with its 37-degree latitude, a 34-degree panel pitch is ideal. Variances in pitch angles show slight differences in solar productivity. A 50-degree pitch yields a 96% efficiency, a 10-degree pitch offers around 94%, and a flat roof provides about 88% of optimal output. However, there’s a more noticeable variation in energy output between seasons with different pitches. The higher the pitch, the more winter production.
