This state-of-the-art Light Dimmer device is a technological breakthrough on many fronts which sets itself apart from other products available in the market.

• Both the processes of dimming and brightening are smooth and continuous resulting in maximum comfort to the human eye.
• Lamps are operated at low current levels without causing the fluorescence light to flicker.
• Highly simplified and compact control circuit which enables space saving by 80% compared to other commercially available products.
• At International Patent Application phase -- proof of its innovativeness and commercial viability.
• Obtained Safety and EMC compliance at TUV-SUD-Singapore.

The innovation is able to create substantial savings in electrical usage for lighting. On average, the saving in energy bill can be as high as 65%. This device offers far better ROI of as short as 1/2 year compare to those in the market (typically 3-5 years depending on the number of light points and wattage).

The project has become a showcase both inside and outside of our campus, such as laboratories/workshops, display area for exhibits, common corridors including a linkway along Commonwealth Avenue West leading to Dover MRT Station. External agencies who have benefitted from the use of the device include the CPF Board, Bugis Junction, Prudential Tower, Alexandra TechnoPark and a number of schools in Singapore.

This system, built in 1996 is for research on solar and wind hybrid operation. It is composed of the following: 2.1kW solar PV system, 2.5kW wind generator and energy storage. The system converts both solar and wind energy into electrical energy for electrical appliances in the laboratory or is stored in the battery bank.

This system, installed in 1996, is to study the performance of a PV system connected to the power grid. It consists of four 4.8kW mono-crystalline solar PV systems. The systems are connected to a low voltage grid and supply the power to the teaching blocks. The system has been operating successfully since its installation.

MicroGrid system, a modern concept for a small-scale localized electricity generation and distribution system, has been developed and operated in SP. The system, integrating different energy sources and energy storages, is able to operate in two different modes: "island" mode" and "grid-connected" mode. Research is underway to optimize the control of the micro-grid system and its efficiency for further commercial applications.

The test bed consists of two different systems: one with 10 different PV technologies and another with 13 different installations. The main objectives of this EDB project are to study the performance of various PV technologies in the tropical region and to investigate the impact of different installations on the energy yield of PV system in Singapore.

Solar energy is used to power lights, fan and notebooks almost directly, with any shortfall augmented by electrical power from the grid. This efficient hybrid system reduces the usage of grid-based electricity from non-renewable, C02 producing sources while avoiding the need for expensive and environmentally un-friendly batteries.

The simulator is a scaled-down electrical power system that is composed of power generation, transmission, distribution and different loads. The simulator is used for training in the operation and control of a power system, fault study and co-ordination of protection relays.

Singapore Polytechnic has been selected by EDB to set up a PV data centre that is capable of monitoring, collecting, analysing and recording the data of ten solar PV systems located at different sites in Singapore. The data analysis will help designers, installers and users of PV system to understand the performance of PV systems installed at different locations of Singapore.
