SunWiz is Australia's Leading Solar Consultancy. SunWiz (and founder Warwick Johnston) have been actively involved in the solar energy industry since 2005.

Since starting in 2005 SunWiz has delivered a vast range of highly valuable intelligence and consulting products and services to solar industry delegates and the broader business community. We have been awarded for our extensive efforts in the solar industry by various organisations. Our PVsell analysis software has been widely accepted as a crucial solar PV business tool and has changed the solar PV landscape in Australia through its innovative and accurate platform.

You may remember SunWiz if you've been to any recent solar industry conference by our mascot labradoodle "Sunny".

We are also well known for:

  • Our essential PVsell software
  • Authoring of Reports for Australia's Peak Body on Clean Energy
  • Key Presentations at most industry conferences
  • Design of multi-award winning PV Systems around Australia
  • Services supporting hundreds of Solar businesses in all states
  • Our up-to-date solar market intelligence


SunWiz's services fall into three broad categories:

  1. Market Intelligence
  2. Solar Design & Engineering, and
  3. Analytical Solar Consulting

Our PVsell software helps hundreds of solar businesses to offer their customers accurate savings projections in their proposals. It also helps to ensure customers all over Australia understand the precise benefits solar is likely to have for their specific case.

For solar businesses who don't require as comprehensive solution as PVsell, we also offer once-off Solar ROI Calculation. This can also be an extremely valuable investment for a business considering solar power as an option because it provides an unbiased, accurate base of what they can expect from solar power. We also offer a Quote Comparison service which is popular among businesses considering their options with solar power.

Our Solar Market Insights service is widely renowned as the most valuable solar intelligence available anywhere. Insights helps many Australian businesses to more accurately interpret the solar market. This can help with strategic planning and may offer many other competitive advantages.

Our ClearView and RETelligence products offer a comprehensive, up-to-date analysis of the STC and LGC markets respectively and are invaluable tools for any business involved in trading these markets.

For the lighter solar business we have also developed a subscription service to cover "everything you need to know about the solar industry" each week. This product is aptly named Woracle.

If you are in the solar industry then we will definitely have a solution to boost your profits in one way or another.
