Solar Panel Tilt Angle in Rwanda
So far based on Solar PV Analysis of 6 locations in Rwanda, we've discovered that the ideal angle to tilt solar PV panels in Rwanda varies between 3° from the horizontal plane facing North in Kibogora and 2° from the horizontal plane facing North in Marembo.
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 Rwanda, the ideal angle to tilt your solar panels will vary by approx 1 degree (between 3° from the horizontal plane facing North and 2° from the horizontal plane facing North).
