When researchers installed a $22,000 solar panel system in a penthouse in Bukit Timah, it not only generated enough electricity to keep 400 50-watt light bulbs running for day, it also became a testament to Singapore's increasing ingenuity in scaling up its solar photovoltaic (PV) installations despite geographical and financing constraints. Singapore has begun exploring the use of "hanging" solar panel systems like what was installed in the Bukit Timah penthouse as well as floating PV systems and energy storage to overcome the challenge of having a small land area that rules out the creation of large solar farms. The hope is that these innovations will increase the viability and attractiveness of solar PV projects as the land-scarce country tries to meet its climate change commitments and become a clean energy hub in Southeast Asia.
