Toshiba Group will contribute to reducing CO2 emissions through the promotion of solar power generation systems designed to provide a steady and efficient power supply.
These days, solar power generation systems of various sizes are often adopted by companies to be used in factories and are also increasingly used in homes, gaining widespread popularity. Solar power generation reminds the image of rooftop solar cell panels, but these panels alone do not complete a system. Output from solar cells is direct current and in order to use this current or to safely connect it to commercial power supply systems, it is necessary to have a power conditioning system (PCS), transformer, switchgear and protection system and protector facilities. Toshiba Group has succeeded in commercializing a high efficiency PCS at the top level in the industry, which is rated as having an output capacity of 250 kW and a maximum efficiency of 97.5%. This PCS can efficiently transform solar energy into electricity, generating a larger amount of electricity than previous models. It is designed compact and lightweight for ease of installation, requiring an area of only 1m2 and weighing 900kg (transformer less type). Using this system in combination with the rechargeable battery, SCiB™, provides an efficient means of controlling solar power output fluctuation, which may present problems, when a large number of solar power generation systems are connected with distribution power grid.
Toshiba Group is able to provide a full range of services from system development to maintenance, as well as products and technologies required for large-scale solar power generation systems for power supply services and for industries. Such technologies include system technologies (such as Smart Grid designed to develop a network of transformers, power supply facilities, dispersed power sources and electricity users) and system engineering technologies for large-scale power plants. Toshiba Group has a track record of quality after delivering more than 100 systems to airports, government agencies and schools and has also delivered about 10,000 PCS to private homes. We will use all our know-how to accelerate the development of the Mega Solar System, which is designed for power supply services and industries and will contribute to reducing CO2 emissions.
