What on earth is the azimuth?
You may have heard the word, azimuth, since considering a solar PV system.
The azimuth is the direction your roof is facing with regard to north (we call this 0 degree).
Depending on the pitch angle of your roof, it may be beneficial to install tilt systems to catch as much sunlight as possible to maximise solar yield
Tracking systems are less common. They have moving parts and need regular maintenance, but because they are always facing the sun they quickly can pay for the extra investment in huge solar yields
Why are some panels tilted?
Drive around and you’ll note that some solar panels are mounted flat on the roof and some are tilted at an angle. What’s the difference? Well in addition to facing north, panels are most efficient at around 90 degrees to the sun’s rays. The ideal angle for the Central Coast and Sydney is about 33 degrees corresponding to our position at roughly 33 degrees south of the equator.
Installing a tilt system requires a few extra components and more planning. But the extra investment can yield extra valuable watts out of your system. Even if a tilt system is not installed initially, the mounting system can always be changed, and tilt frames added later.
In some cases, we can install an adjustable tilt system, allowing your panels to sit at (or near) 90 degree angles to the sun all year round.
