JTC has initiated a groundbreaking pilot project to develop Singapore’s first overhang solar photovoltaic (PV) system at 15 Woodlands Loop. This innovative approach seeks to optimise solar deployment by constructing PV systems on overhang structures between multi-storey industrial buildings, offering an alternative to traditional land-based or rooftop installations. The pilot is part of JTC’s broader strategy to expand solar energy production by utilising untapped spaces within industrial estates.
As of the second half of 2025, Singapore has deployed 1,775.4 MWp of PV systems, surpassing half of its 2 GWp solar target by 2030. However, with conventional sites nearing saturation, the need to co-locate solar with existing infrastructure has become crucial. The overhang PV systems present unique engineering challenges, such as ensuring structural integrity and safe access for maintenance, which will be addressed during the 15-month design and testing phase.
The pilot aims to achieve a minimum installation capacity of 250 kWp across a 4,300 m² void space. Upon successful installation, the system will operate for 10 years, contributing electricity to the national grid. JTC plans to assess the feasibility of replicating and scaling this model across other industrial estates, potentially unlocking additional solar capacity.
Finn Tay, Chief Sustainability Officer at JTC, emphasised the importance of innovative solutions in a land-scarce nation like Singapore, stating, “This pilot is one example of how we are rethinking underused spaces to unlock new solar potential and support Singapore’s long-term energy goals.”
