Wallsend Library

Page hero image

A solar photovoltaic (PV) system has been installed on the award-winning Wallsend District Library, which is the newest of the Newcastle Region Library facilities.  Opened in 2006, the Library offers a wide range of resources and facilities to the community including study rooms, meeting rooms and an exhibition area. 

To reduce electricity costs, the Wallsend District Library’s roof space was identified as a highly suitable location for photovoltaic technology.  Following a comprehensive review of the steel sheet roof top’s ability to support 18kg per square metre of solar PV systems, an 80 kW grid-connected solar system consisting of 308 panels was installed.  The installation works were undertaken out-of-hours to minimise the disruption to staff and library patrons.  The solar PV will significantly decrease the Library’s reliance on grid-generated energy usage and is anticipated to reduce energy and peak capacity costs by approximately $15,000 per annum.

The solar PV system will reduce Council’s exposure to rising electricity prices while helping to meet its goal of having 30% of Council’s electricity generated from low-carbon sources by 2020.
