Solar Panel Tilt Angle in Ethiopia

So far based on Solar PV Analysis of 22 locations in Ethiopia, we've discovered that the ideal angle to tilt solar PV panels in Ethiopia varies between 14° from the horizontal plane facing South in Aksum and 7° from the horizontal plane facing South in Warder.

These tilt angles are optimised for maximum annual PV output at each location for fixed-panel solar PV installations. If you click on one of the locations above, there is further detail on ideal seasonal tilt angles as well (in case your solar panels are adjustable).

Depending on where you are based in Ethiopia, the ideal angle to tilt your solar panels will vary by approx 7 degrees (between 14° from the horizontal plane facing South and 7° from the horizontal plane facing South).
