JTC launches tender for Singapore’s first overhang solar PV

The project tests solar viability over void spaces between multi-storey buildings.

JTC has launched a tender to develop Singapore’s first overhang solar photovoltaic (PV) system at 15 Woodlands Loop.

“The pilot project tests the viability of PV systems on overhang structures constructed across void spaces between multi-storey industrial buildings, to serve as an alternative to conventional land-based or rooftop installations,” JTC said in a statement.

The first stage of the project involves designing, constructing, operating, and testing the overhang solar structure over 15 months.

A key success indicator for the pilot is to achieve a minimum installation capacity of 250 kilowatt-peak (kWp) across the identified void space of about 4,300 square metres between the buildings. Upon successful installation and commissioning, the project will then be operational for a 10-year period, where generated electricity will be exported to the national grid.

JTC will also study the potential to replicate and scale the deployment of similar overhang PV systems across other industrial estates.
