Important Disclaimer

These angles are a scientific estimate for guidance only. The single most important factor for any installation is to ensure the panels are **100% shadow-free** during peak sun hours (approx. 9 AM to 3 PM).

A minor deviation in tilt angle (5-10°) has a much smaller impact on energy generation than even a small, consistent shadow from a tree branch or a chimney. Always prioritize a shadow-free location.
