No doubt many of our community would have seen the new solar cells recently installed at our school. Perhaps you’ve wondered why?
As a School we are keen to model good stewardship of the resources that God provides to our students and their families, and the installation of the 87kW system has allowed us to reduce our energy footprint by approximately 35%. In addition, it also makes good financial sense! Once the system is paid off we expect to save about $19,000 a year in energy costs.
For those interested in that type of thing, DCS installed 332 new solar panels on four roof spaces, boosting the existing 17kW solar system to a total of 404 panels and 100 kW. The additional system will generate about 137 MWh per year, making a total annual generation of around 165 MWh. This performance has been guaranteed by the installer.
A part of our due diligence to determine the most appropriate system size involved us engaging a third party to critique a number of quotes. In this case, a former student, Murray Halyburton (DCS Class of 1991), from Energy Management Services, assisted in the analysis of the options. The outcome has allowed us to form a realistic view of the new system’s capabilities and the potential long term savings.
