DNATA Singapore, A prominent global provider of air and travel services is actively enhancing resource efficiency worldwide by making significant investments in infrastructure and equipment. DNATA Singapore has taken the initiative to install a 3.5 megawatt-peak rooftop solar power system across its operations, including its cargo and catering facilities at Changi Airport (SIN). This advanced rooftop power plant, featuring over 6,500 solar panels, generates more than 4,300 megawatt hours of green energy annually, helping the company cut its electricity-related carbon emissions in Singapore by 20% each year.

As professional solar system owners, Sembcorp Solar addresses the insurance and engineering challenges associated with placing solar panels on membrane roofs. For instance, we incorporate a protection mat between the ballast stones and the roof, ensuring the solar racking system remains secure without directly contacting the membrane. This precaution is essential, as solar structures require approval from the waterproofing contractor to prevent damage to the roof, which can experience temperatures of up to 90 degrees Celsius. Thermal expansion in the metal components of the solar structure could otherwise harm the membrane.

To further mitigate risks, Aerocompact structure are designed with protection mats compatible with Sika, Mapei, and Firestone membrane rooftops. We also limit the array size to a maximum of 40m by 40m for a responsible and durable design. Without these measures, the solar structure might produce popping sounds at night during cooling, accelerating its degradation and shortening its typical lifespan of 25 to 30 years.
