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 panels not compliant or approved for use in Australia

  2. Locating the solar panels on shaded parts of the roof is going to hurt your daily solar yield.  Having solar PV panels that face the sun at some point during the solar day is also important. 

  3. Adverts on TV/ door-knockers – please carefully research what they offer, including the components. A simple Google search on the company name, ABN # and the accredited installers # is worth doing. Ask for references and contact past customers. 

  4. Waiting for new technology  – yes, solar power technology is constantly evolving. Our advice is to choose products that have large research and development programs, and innovate. Not just products that sell the most 

  5. Warranty – can’t stress the importance of this one enough.  While you will pay more for quality products, but the warranty the top players are happy to provide will tell you how confident they are with their equipment. * May 2018 – LG for example have just released a solar panel that comes with a 25 year warranty 

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 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.
