Commentary: Can Singapore construct sufficient rooftop solar panels for its energy wants? – CNA


Singapore’s evolving solar panorama might be in comparison with ongoing efforts for self-sufficiency in its water provide. It just isn’t that we should not have sufficient rainfall to satisfy our wants, however relatively that the infrastructure for capturing, storing, distributing and recycling rainfall needs to be up and operating to understand its full potential. Public training and expertise should additionally go in direction of minimising waste.


A second impediment to a big enhance within the stage of electrical energy generated from solar PV in Singapore is house. Singapore is a closely built-up metropolis, which already faces a number of competing calls for for land. 

According to the EMA, as of March 2021, there have been 4,585 grid-connected solar PV installations in Singapore. Their whole capability quantities to an round 443-megawatt peak (MWp), with the non-public sector contributing most of it (53 per cent), adopted by city councils and grassroots models (38 per cent).

There are different applied sciences for optimising what little house Singapore has for solar panels. These embody cellular solar PV methods that can be utilized on quickly vacant land and relocated as mandatory, and building-integrated PV during which solar panels are included right into a constructing’s facade.

While most of those installations are on rooftops, floating solar PV services may contribute considerably to solar PV capability. The 60MWp Tengeh Reservoir plant, launched in July 2021, can power 16,000 four-room HDB flats and scale back emissions equal to taking 7,000 vehicles off the street. Other floating tasks are within the pipeline.

But rooftops nonetheless present probably the most available house for large-scale rollout. According to the 2020 SERIS report, the whole web usable space for rooftop PV deployment in Singapore is roughly 13.2 sq km.
