SINGAPORE - Having grown its solar capacity by more than seven times since 2015, Singapore is now one of the most solar-dense cities in the world. The Republic took one big step towards environmental sustainability when its first large-scale floating solar photovoltaic (PV) system at Tengeh Reservoir - about the size of 45 football fields - was officially opened on Wednesday (July 14). Prime Minister Lee Hsien Loong was the guest of honour at the event. This latest solar farm in Tengeh, which has a capacity of 60 MWp, will contribute to to the country's plan to install at least 2 GWp of solar PV capacity by 2030. The project will give the nation's solar and renewable energy industry a boost, paving the way for more such facilities to be built here and in the region, Mr Lee said. The idea of building a floating solar farm came up a decade ago when Singapore was looking for ways to harness solar energy at scale. This became an increasingly viable option as the cost of solar cells came down. Building a floating solar farm also helped to capitalise on the large surface area of reservoirs and allow for solar deployment to be scaled up, the PM added. Spread across 10 solar-panel islands,...
