What is a tier one solar panel?

You may have heard of Solar PV Systems described as Tier One, Tier Two or Tier Three. Actually those ratings really describe the manufacturer of the system. It's essential you know where your system is from, its warranty details and if it is made for Australian conditions.

Tier One Solar Panel

Common solar power pitfalls

Redshift Solar will steer you away from these common mistakes.

  1. Installing of solar PV panels not compliant or approved for use in Australia

  2. Getting an inverter that is not sized for the particular solar PV panels and their voltage ranges

  3. Locating the solar PV panels on shaded parts of the roof is going to hurt your solar PV yield.  Having solar PV panels that face the sun at some point during the solar day is also important. At no stage should solar PV panels be installed on a south facing roof.

  4. Not understanding how solar panels work. For example, solar panels are not as efficient if they are too hot, and can even damage the inverter with high voltage first thing on a cold morning if the system calculations are not done correctly. We do the maths to make sure your solar PV system stays on and will be reliable.

  5. Waiting for new technology. Yes, solar power technology is constantly evolvin, but if you keep putting it off, you’re costing yourself time and money. 

Tilted Solar Panel

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.
