Note: Optimal tilt maximizes annual POA irradiance. Winter bias is useful for off-grid systems needing consistent winter production. Adjustable mounts can increase yield 5-10%.

Reference

Annual Optimal Tilt ≈ Latitude × 0.9 Summer Bias ≈ Latitude × 0.76 Winter Bias ≈ Latitude × 1.1 + 5° Back Height = Module_L × sin(Tilt) Base Length = Module_L × cos(Tilt)
