Expected ROI of rooftop solar battery project in Singapore 2026

What is Singapore's largest rooftop solar system?

With a capacity of 38 Mega-Watt peak (MWp), this project is slated to be Singapore’s largest single-site rooftop solar system when completed in 2025. The system will generate enough clean energy to power over 10,000 four-room HDB flats annually, equivalent to emissions reduction of nearly 20,000 tonnes per year.

Will Changi Airport's rooftop solar system be Singapore's largest single-site solar system?

Changi Airport Group (CAG) has partnered with Keppel Ltd. to develop a major solar photovoltaic (PV) system across the rooftops of Changi Airport’s terminal buildings. With a capacity of 38 Mega-Watt peak (MWp), this project is slated to be Singapore’s largest single-site rooftop solar system when completed in 2025.

Will AA REIT install rooftop solar PV system in Singapore?

What is a good PR value for a solar system in Singapore?

Well-designed PV systems in Singapore have an initial PR value of above 80%. Minimum PR for system installed under the SolarNova programme currently is ~75%. There is a small annual degradation of the PV module output, which should be within the limits specified in the manufacture’s performance warranty.

Why should Singapore invest in solar power?

This influx of renewable power is vital for diversifying the nation’s energy mix, reducing its heavy reliance on imported natural gas, and enhancing its energy security. The SolarNova program is a major contributor to Singapore’s national solar targets of 1.5 GWp by this year and an ambitious 2 GWp by 2030.

How will Singapore's solar adoption impact the future?

While this does not impact solar adoption directly, it does marginally increase the cost of electricity generation for natural gas and other thermal plants in Singapore. This, in turn, might make solar energy more competitive in the future.
