SunWiz has had years of experience in designing innovative solar systems. Installations designed by SunWiz work right first time and often can be implemented at lower costs due to clever planning. For example SunWiz created a panel numbering system to systemise the ease of install and thus reducing the cost of installation. This is just one of the many solutions possible with a SunWiz design. Â Examples of large scale system designs completed by SunWiz include the Metricon Stadium, Ballarat University, Tulla-Calder Interchange.
