As cities in Asia grow economically, they would also need to be smarter in their energy usage and management. What would smart cities with energy management of households, buildings and local communities look like? To find out more, Asia is Green looks at a smart city project in Japan.

The Yokohama Smart City Project (YSCP) is one of the largest smart city demonstration projects in Japan, piloted in three Yokohama districts – the Minato Mirai 21 district, the Kohoku New Town district, and the Yokohama Green Valley district. This project was selected as a Next Generation Energy Infrastructure and Social System Demonstration Area by the Ministry of Economy, Trade and Industry in April 2010, and is expected to be completed by 2014.

Large-Scale Solar Projects and Plants in Japan

Asia’s demand for energy is increasing, and part of this demand could be met by the introduction of large-scale solar projects and plants.

Asia is Green takes a look at Japan, where the move away from nuclear energy after the Great East Japan Earthquake and the Fukushima Daiichi Nuclear Power Plant accident in 2011, would result in more large-scale solar plants replacing her energy needs.

In order to accelerate the supply of solar energy, the Japanese government implemented the revamped feed-in-tariff (FIT) scheme in July 2012, which stipulates that solar installations producing more than 10 kW of energy be subsidised with a feed-in-tariff of 42 yen per kWh for a period of 20 years.

NCCS-NRF Symposium

The National Climate Change Secretariat (NCCS) and the National Research Foundation (NRF) recently commissioned a series of six Technology Primers, which were presented at the NCCS-NRF Symposium on ‘Energy Resilience for Sustainable Growth’ on 4 Aug.

The Technology Primers bring together research experts in Singapore to explore the potential of various technologies that can help Singapore improve its energy efficiency and security, and reduce its carbon emissions.

Each Technology Primer summarises the state of the technology and its feasibility for Singapore, and also includes current research activities and possible research goals. Read more

Understanding the Solar Landscape in Singapore with the National Solar Repository

solarparkThe National Solar Repository of Singapore (NSR) was launched in Nov last year, and is administered by the Solar Energy Research Institute of Singapore (SERIS), the Economic Development Board of Singapore (EDB), Singapore Polytechnic, and Ngee Ann Polytechnic.

The NSR serves as a one-stop platform for those interested in understanding the solar landscape in Singapore. The NSR publishes a map and database of the solar photovoltaic (PV) systems installed at commercial, industrial and residential buildings in Singapore. Read more

Solar outlook for the region looks bright for SANYO

Green Business Singapore recently met up with Dr Hiroyuki Kuriyama, Division President for Energy Systems & Solutions, SANYO Asia Pte Ltd, to understand more about SANYO’s solar products and market outlook.

From the discussion, we believe that the solar outlook for the region looks bright for SANYO, given its superior solar technology, its solar installations successfully tested in the field, and the growing opportunities for solar in Singapore and the region.

Superior Technology

SANYO has more than 30 years of experience in solar technology, and its HIT (Heterojunction with Intrinsic Thin layer) solar cells has the world’s highest energy conversion efficiency. The HIT solar cell is an original technology developed by SANYO, and is composed of a mono thin crystalline silicon wafer surrounded by ultra-thin amorphous silicon layers.

Dr Kuriyama explains that the HIT solar cell can achieve the highest cell efficiency of 21.6% and highest module efficiency of 19%. The higher conversion efficiency of HIT solar modules means that more energy can be generated per installation area. This is beneficial in Singapore with our limited land and roof space.

The HIT solar cell can also maintain higher efficiency at high temperatures as compared to a normal crystalline silicon solar cell. This means that the HIT solar cells are suitable for Singapore’s hot climate and would experience less drop in efficiency. In addition, the HIT solar modules are lighter, and more environmentally-friendly as they are lead-free. Read more
