As a proud family owned and operated Australian manufacturer of high quality lockers, seating and change room furniture, Excel Lockers understands that their company has moral, legal and continuing obligations to limit their impact on the environment, and has set goals and targets with their Environmental Policy.

Excel Lockers is clearly committed to continuous improvement in this area. As part of Excel Lockers’ energy efficiency initiatives, SOLAR HYBRIDS designed and installed the solar power system on their factory roof at Darra in Qld. The PV array consists of 260 x 350 watt highest quality LG solar panels with a combined capacity of 91kWp.

The solar panels are connected via 260 x SolarEdge DC Optimisers to 5 x SolarEdge 3-Phase inverters. The Optimisers are small electronic devices installed beneath each solar panel that enable panel-level monitoring and ensures each module panel is continually kept at maximum power. Electricity losses due to mismatch or partial shading conditions are also kept to a minimum through the use of SolarEdge Optimisers.

Additionally, this SolarEdge system also provides a superior level of safety. The DC-DC optimisers revert to ‘extra low voltage’ when the system is switched off during daylight hours. If an accident occurs, the system will automatically isolate to safe mode once the communications link is reached or the system is shut down. This allows firefighters to operate safely and use water to push back a flame front.

The Solar Hybrids team designed the system, procured the components, and project-managed the build from start to finish, ensuring a safe and successful implementation of the highest quality system with minimal disruption to the factory’s operations. This solar installation adds to Excel Locker’s already impressive eco-sustainability and environmentally friendly energy efficiencies such as their LED lighting throughout their factory and storage facilities.
