A prominent global provider of air and travel services is furthering its commitment to enhancing resource efficiency worldwide through significant investments in infrastructure and equipment. DNATA Singapore has implemented a 3.5 megawatt-peak rooftop solar power system across its operations, including its cargo and catering facilities at Changi Airport (SIN). This rooftop power plant, consisting of over 6,500 solar panels, will produce more than 4,300 megawatt hours of green energy annually, enabling the company to reduce its electricity-related carbon emissions in Singapore by 20% each year.

As professional owners of solar systems, Sembcorp Solar understands the insurance and engineering concerns associated with placing solar panels on membrane roofs. Upon close inspection of the ballast roof solution, you will notice a protection mat placed between the ballast stones that weigh down the solar racking. This precaution is necessary because the solar structure cannot be placed directly on the roof without approval from the waterproofing contractor. The roof is exposed to temperatures that can reach up to 90 degrees Celsius, causing the metal material in the solar structure to undergo thermal expansion, which can easily damage the membrane roof. Our solar structures are equipped with a protection mat that can be customised to be compatible with Sika, Mapei, and Firestone membrane rooftops. Additionally, our installation is designed with a maximum array size of 40m by 40m to ensure responsible design. Without this consideration, the solar structure could produce a popping sound at night when it cools down after heating up during the day, accelerating the degradation of the solar structure’s lifespan, which typically ranges from 25 to 30 years.
