Formula and working
optimal tilt ≈ latitude; penalty ≈ cos(tilt deviation) × cos(azimuth deviation)
- 1
Collect the inputs
Site latitude = 40 °; Actual panel tilt = 30 °; Azimuth deviation from true south/north = 20 °
- 2
Apply the formula
optimal tilt ≈ latitude; penalty ≈ cos(tilt deviation) × cos(azimuth deviation)
- 3
Result
Estimated relative output = 92.5 %
