University of Melbourne installs 100kW solar system on landmark building – adopting unique panels and without STC’s
Apr 14, 2015
University of Melbourne recently completed a 100kW solar system on the landmark Wilson Hall building, without the assistance of an up-front STC discount and adopting unique flat mounted panels. Final commissioning presented a celebrated milestone after initial scoping of the project commenced in early 2014. The installation presented numerous challenges which were overcome by the project team. Enhars’ role in this landmark project included initial scoping of the system, a detailed solar options report, preparation of request for tender documentation, tender evaluation and project management. The feasibility and options reporting included technical and financial viability of various solar PV design options. Due to the structural and heritage limitations of the building, a flat mounted solar system was the only viable option for solar PV installation.

It was critical that the flat mounted array was duly considered in the tender responses, the difficult building constraints fully understood and the ongoing additional maintenance allowed for. Enhar completed tender evaluation and the selected supplier, Energy Matters (SunEdison) adopted Trina glass on glass, frameless panels as the preferred solar PV panel and included an innovative cleaning system within the tender response. The frameless panels minimise pooling of water on the flat array and increase required cleaning intervals, comparatively to conventional framed panels where pooling and debris build up on the frame occurs.

Enhar provided project management services to the University of Melbourne during the installation phase. An ongoing maintenance program will be initiated, with separate arrays undergoing different maintenance regimes and monitored separately. This will allow the optimum maintenance solution to be determined and provide a reference for maintenance requirements of flat mounted arrays to ensure ongoing performance.
