St Lucia Solar – 7.2kW
The site for this project was a dental practice in St Lucia, Brisbane. The owners of this business approached Voltio looking for a way to reduce their energy costs. Voltio reviewed their energy usage profile and recommended a small solar installation, to help offset their grid supply costs.

Using the flat, concrete roof to our advantage we were able to install an almost hidden design. The system consists of twenty 360kW Sunpower solar panels, together with a a 7KW Fronius Symo inverter. As an added advantage Voltio ensured this equipment could integrate with a battery at a later date as well.
St Lucia Dental are expected to save $2,818 each year in the first three years of operation, growing to $4,293 per year during the 15 year contract term. Their overall savings estimate is $64,402.
