What on earth is the azimuth?
You may have heard the word, azimuth, since considering a solar pv system.
The azimuth is your roof's angle with regard to north (we call this 0 degree). The parts of your roof facing to Azimuth 0 degree (or as close as possible to it) are ideal for placement of solar panels.
Think of it like a watch-face. 12 o'clock is Azimuth 0 degree. (North for those of us in the southern hemisphere.) South is like 6 o'clock on the watch face, and Azimuth 180 degrees.
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 (including the pitch of your roof), corresponding to our position at roughly 33 degrees south of the equator.
Obviously, installing a tilt system costs more in materials and install time and requires more planning. But the investment is worth the cost by getting 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.
