The adoption of solar energy at Mactan Cebu International Airport (MCIA) marks a significant milestone in sustainable aviation infrastructure. Spearheaded by Solenergy Systems Inc., this groundbreaking project involves the installation of over 6,300 photovoltaic (PV) modules on the roof of MCIA’s Terminal 1. This initiative not only underscores the airport’s commitment to renewable energy but also sets a benchmark for other airports worldwide.
Transforming Energy with Solar Power
The solar grid-tied system at MCIA is engineered to generate approximately 2,169,900 kWh of energy annually. This substantial output will effectively offset a significant portion of the airport’s daytime energy demands, contributing to the reduction of its carbon footprint by saving an estimated 1,301,580 kg of CO2 each year. The 1.64MW PV system is a testament to the collaborative efforts of GMCAC, a consortium led by GMR Group and Megawide Construction Corp., and Solenergy’s expertise in large-scale solar projects.
State-of-the-Art Technology and Design
Solenergy’s implementation of advanced technology is evident in the installation of 65 Fronius Symo 3-phase inverters. These inverters provide real-time online system monitoring and enhanced safety features, including arc and ground fault protection. The custom-designed racking system, featuring a cast-in-place ballast solution, ensures resilience against the high wind speeds typical in the Visayas region.
Additionally, Solenergy supplied a bespoke curtailment solution, allowing the PV system to operate alongside the airport’s gensets during power outages. This integration highlights Solenergy’s capability to deliver comprehensive and adaptable power solutions.
Enhancing Airport Infrastructure
Beyond the solar installation, Solenergy was tasked with the re-engineering of Terminal 1’s power room. The project included the design, supply, and installation of panelized switchgear and a resin-encased busduct system, showcasing Solenergy’s ability to provide sophisticated AC-side power solutions.
This holistic approach was pivotal in meeting GMCAC’s requirement for a full-service contractor capable of executing their ambitious power plant vision. Solenergy’s track record and innovative solutions made it the ideal partner for this transformative project.
Setting a Global Example
Airports globally are increasingly recognizing the benefits of solar power installations. With ample available space on rooftops, car parks, and surrounding areas, airports are uniquely positioned to adopt large-scale solar systems. MCIA’s initiative not only promotes clean energy but also serves as a powerful visual endorsement to millions of passengers who witness the solar arrays upon arrival and departure.
A Brighter Future
The solar installation at MCIA coincided with Terminal 1’s renovations, including roof re-waterproofing and repainting. Two mounting systems were employed: Clenergy EZ-rack for the tin roof and Clenergy Solar Matrix for the concrete roof ballast solution. The Fronius Symo 24.0 kW inverters, suitable for outdoor use (NEMA 4X), are perfectly suited for commercial applications with a 480V grid connection.
Solenergy, as the exclusive Service Partner Plus, provides comprehensive in-country warranty support. Lightning protection devices further safeguard the PV system, ensuring long-term reliability and efficiency. A custom Busduct system enhances the connection to the 4000AT switchgear, underscoring Solenergy’s commitment to excellence in electrical engineering.
As airports continue to embrace renewable energy, projects like MCIA’s solar power installation pave the way for a more sustainable future in aviation, setting a precedent for environmental responsibility and energy efficiency worldwide.
