SunWiz Solar Consulting


SunWiz was formed in 2009 when the lack of Australian solar engineering services was observed.

Building upon seven years engineering experience, five years of solar energy design, installation, and consulting, SunWiz entry into the market was elegantly timed. The launch of the "Successful Solar Strategies" report occurred one week after the REC market crashed, just as SunWiz had predicted. In the interests of the Australian solar energy industry, four excerpts of the report were released over the course of a week. These, completed by the in-depth full report, illustrated why the REC crisis had occurred, was here to stay, the impact it would have on solar businesses, and many excellent strategies that smart business could use to survive and succeed.

Since then, SunWiz has assisted many solar businesses refine their marketing, improve their processes, and expand their sales. Find out what SunWiz can do for your business.
