Land scarcity has severely limited Singapore’s adoption of solar power. Floating solar panels may be a viable alternative for the city-state surrounded by water. Floating solar panels could be eleven percent more efficient than solar panels placed on precious land. Technology leader in the field, ABB is providing critical components on a landmark one megawatt floating solar photovoltaic test-bed. It measures 1 hectare or 1.5 football fields. The energy generated will be fed into the national energy grid, providing electricity for up to 250 households.
“We are proud to support this important project in Singapore with our technological expertise and domain knowledge,” said Tarak Mehta, president of ABB’s Electrification Products division. “This project is perfectly aligned with our Next Level strategy around the energy revolution and is an important step in collaborating with partners to bring more renewables into the future energy mix.”
Located in the Tengeh Reservoir in West Singapore, the installation features multiple solar solutions from providers to study the performance and cost-effectiveness of floating solar platforms. ABB supplied 100 kW of market-leading TRIO-50 solar inverters to Phoenix Solar, one of several system integrators for the project. These essential components convert the direct current produced by solar panels into alternating current for use in electrical grids. Additionally, ABB low-voltage moulded case and miniature circuit breakers protect the electrical circuits on the water.
In Singapore – a country with an area of only 719 square km and a population of 5.6 million – high average annual solar irradiation of about 1,500 kWh/m2 makes solar an attractive source of renewable energy. Floating solar platforms will be naturally cooled by the surrounding water, which increases the efficiency of the energy yields significantly. A study has found that the natural cooling effect of the water beneath the solar cells makes them up to 11 percent more efficient than solar panels placed on land. In a synergistic effect, the floating platform helps reduce evaporation of the valuable water.
ABB has claims to be a pioneering technology leader in electrification products, robotics and motion, industrial automation and power grids, serving customers in utilities, industry and transport & infrastructure globally. Continuing more than a 125-year history of innovation, ABB today is focused on the future of industrial digitalization and driving what it sees as the Energy and Fourth Industrial Revolutions. ABB operates in more than 100 countries with about 132,000 employees.
