The numbers speak for itself: Pre and Post Solar Expenditure and Consumption at Bundaberg Christian College
The Bundaberg Christian College (BCC) solar installation is the largest hybrid system of its kind in Australia. It supplies the school with electricity during the day while the battery storage comes into play during peak demand hours, shoulder hours and the evening.
The combination of solar with with a switch to 1,500 LED lights as well as a range of other energy efficiency measures resulted in an immediate halving of electricity consumption. That meant a direct cost reduction for the project because less solar needed to be installed.
Local network requirements meant that GEM’s Engineering team had to custom-engineer a site master controller for smooth charging and discharging. To get the state-of-the-art system running at maximum efficiency we have kept monitoring the site to make improvements.
The school is keen to go completely off-grid within the next few years and we are working towards that together. BCC really positions itself as a prime learning ground for sustainability, economics and engineering.
GEM Energy’s electrical engineering team, made up of Dimitar Iliev and Ben Kolle, even won a prize for this highly customised solar installation at the 2016 Clean Energy Council’s (CEC) Solar Design and Installation Awards. The event honours innovation and skill in the relatively new field of commercial solar installations. Read the full story here.
