Case study
Raiden Technologies designed and installed a 13.2kW three-phase rooftop solar system for the new 40-place public preschool at Hebersham Public School, giving the building clean, low-cost daytime power from its first day.
A 13.2kW three-phase solar system suits a 40-place preschool because its power use peaks during daylight hours. Raiden installed one at Hebersham Public School using 30 Trina panels and a Fronius 15kW inverter.
Raiden supplied and installed a 13.2kW rooftop solar system on the new preschool at Hebersham Public School, built to the NDY engineering specification. Thirty Trina all-black panels feed a Fronius 15kW three-phase inverter, with a Fronius smart meter tracking production and use in real time.
The new preschool needed a solar system to cut its running costs and meet the Department’s sustainability goals, delivered as part of a busy new build. The system had to meet the engineering specification, connect safely to a three-phase supply, and look neat on a new building used by young children and families.
Raiden installed 30 Trina all-black 440W panels on mounting brackets, with all cabling and containment. They connect to a Fronius 15kW three-phase inverter, and a Fronius 63A three-phase smart meter gives staff clear visibility of solar production and building energy use.

30 × 440W Trina all-black panels, 13.2kW in total.
Fronius 15kW three-phase inverter, matched to the preschool’s supply
Fronius 63A three-phase smart meter for real-time monitoring of production and use.
Mounting brackets, cabling and containment installed to specification.
The preschool now generates much of its own daytime electricity, which cuts grid power use and running costs during the hours it is open. The smart meter gives the school clear data on production and use, which supports its sustainability reporting.
Testimonial
““Raiden delivered the solar as part of our new preschool build without any disruption. The system looks great on the roof, and being able to see exactly how much power we’re producing makes it easy to share our sustainability story with families. It’s a great outcome for the school and the community.””

It depends on energy use and roof space. For Hebersham’s 40-place preschool, the specification called for a 13.2kW system, which Raiden delivered with 30 Trina 440W panels.
Yes. Schools use most of their power during the day, exactly when solar is producing, so they use most of what they generate on site. That means lower bills and a quicker return than most residential systems.
Most commercial and school buildings run on three-phase power. A three-phase inverter like the Fronius 15kW spreads the solar output across all three phases, so the system can run at full capacity and stay within network rules.
Roughly 45–55kWh a day on average, or about 17,000–19,000kWh a year, depending on roof orientation, tilt and shading. Raiden models the expected output for each site before installation.
With a smart meter and the inverter’s online portal. The Fronius smart meter at Hebersham shows real-time production and building use, so staff can track savings and report on sustainability.
