CASE STUDY: UNIVERSITY OF QUEENSLAND GATTON LIBRARY WAREHOUSE

Infinity Solar successfully tendered on a 107kW project at the University of Queensland’s Gatton campus and worked closely with McNab Constructions and SKM-S2F architects to deliver the turnkey solar solution.

Due to the fragile roofing material specified by the architects the installation called for a unique mounting solution. During the design phase Infinity Solar’s expertise was called on by the builder and architect to advise on the best method to roof mount over 440 solar panels to this fragile material.
In partnership with Schletter (one of the world’s largest solar panel mounting companies) a solution was developed that ensured not only the integrity of the roofing material but also that the roof warranty remained intact. Most of the mounting system was available from Schletter Australia however Infinity had to fly over 1500 custom designed roof clamps in from Germany.

Even though this 107kW system is one of the largest of its type in Queensland the University stipulated that the design must also allow for future expansion. This requirement meant that Infinity Solar had to initially design the system to its future size, but only build the first 107kWs now. Providing for this future expansion not only meant that the initial 448 solar panels had to be located exactly to plan but the cable runs and inverter room also had to be designed to accommodate at least another 100kWs. Installing such a large roof top solar system, and in an area that is well known for its bad weather, required certification from the Registered Professional Engineers of Queensland (RPEQ). In consultation with the RPEQ Infinity Solar gained this certification which approved the structural integrity of the roof top solar array and mounting system. As the library warehouse building is orientated East/West the solar array was designed to take full advantage of the sun’s path with the system to be split equally across both the East and West side of the rooftop. This design would guarantee maximum generation given the roof orientation and pitch.

Infinity Solar also designed and installed a dedicated data logger and multifunctional metering that would provide the University with generation and yield data. This data is regularly collected and is used to better understand the seasonal and environmental impacts on the solar system.
