SOLAR OPTIMISATION
ANGLE TO THE SUN
REDARC solar panels will perform at their peak with the panel face angled directly towards the sun.
In practice this is not always achievable, so REDARC recommends having your panels face NORTH
at an angle of between 20° and 40° from the ground. This will ensure the best total output from
your panel across the course of the day, no matter what season.
In the southern hemisphere, the sun is always in the NORTH half of our sky. As such facing your
panel NORTH ensures the best angle to the sun for a fixed panel across the course of the day.

The optimal angle from ground of the panel is around 30°. Anywhere between 10° and 40° ensures
good power generation across the course of the day.
