We only use Tier 1 solar panels. For you, that means the highest quality product that will get you the best results. Solar isn’t just our business… it’s our passion. We understand all the ins and outs of the solar industry. We know what makes a good panel and what will give you the best possible performance.

And when it comes to solar panels, quality is everything.

Installing quality solar panels on your roof will give you a better result in terms of the energy you are able to produce. The modules used in quality panels perform to a higher standard and are more efficient at how they convert the light from the sun into electricity. It really is a case of getting what you pay for.

Made for the Australian climate

Made for the Australian climate

Australia was made for solar… we are the sunburnt country after all!

So while we have the perfect climate for solar energy, many solar panels can’t stand up to the hot Australian sun. Ours can.

When you look at performance in extreme temperatures, there are two things you need to consider.

  1. The temperature co-efficient rating, or how much energy each cell loses as the temperature rises
  2. The operating module temperature, or the minimum and maximum temperatures at which the solar panels will work

Our solar panels offer both a high-temperature co-efficient rating as well as operating module temperatures of -40℃+85℃.
