Best Roof Orientation
South-facing roofs in Telangana get maximum sun exposure, boosting output by 10–15% vs East/West facing roofs.
Shadow-Free Zone Critical
Even partial shadow on one panel reduces the output of the entire string. Ensure at least 70% shadow-free area.
Spacing & Maintenance
Allow a minimum 1.5-foot gap between panel rows for monsoon drainage and ease of cleaning access.
