218.9 kWp / 200 kVA SOLAR PV ROOFTOP SYSTEM
Perdaman Advanced Energy (PAE) has been engaged in two successive projects to design, install, and upgrade the solar PV system at Balga Leisure Park, progressively increasing its overall capacity and operational efficiency.
The first stage, completed in October 2017, delivered a 75.54 kWp rooftop solar PV system, supporting the facility’s growing energy needs. As energy demand continued to rise, a second stage commenced in September 2025, adding 143.36 kWp of new capacity. This upgrade involved the replacement of outdated inverters with advanced models, enabling seamless integration and centralized system control. Additionally, the project included re-stringing of existing panels to enhance performance and ensure compatibility with the new system architecture.Upon completion of both stages, the site will have a total combined capacity of 218.9 kWp with a 200 kVA inverter system.
Due to the facility’s complex roof layout, panels were transported to different roof areas using a combination of crane lifts and scissor lifts. Special care was taken to avoid installing panels along the roof edges directly above the basketball courts to ensure safety. As the second phase progresses, power shutdowns are being carefully scheduled during non-operational hours to avoid disruptions to the aquatic centre’s daily activities.
