Company Overview

SunWiz is an Australian solar consultancy, founded by Warwick Johnston in 2009.

We spend our time crunching solar numbers into useful industry insights and developing strategies to help solar businesses succeed. We offer solar market intelligence products, guidance, software, assistance and reports - all carefully designed to help the solar industry to grow and prosper.

SunWiz spent its first 8 years based in Byron Bay, before moving to Eltham in Melbourne's North-east in 2015 - though our clients are all around Australia. We also attend and present at most solar industry events in Australia and also some around the world.

We are open for business from 9:00am to 5:00pm on weekdays.

Warwick started SunWiz in order to make a positive impact on the solar industry in Australia. Our mission is to help solar businesses grow and prosper sustainably with the ultimate goal of seeing solar panels on every roof in Australia.

Our products and services help solar businesses to operate more effectively and efficiently with intelligent analysis of key information.

The types of solar businesses we help include:

The office mascot and aptly named "Sunny" clearly lends his broad solar wisdom to everything we do.
