Rooftop Solar Energy Hong Kong Produces 880 Million Kilowatt-hour Electricity Annually

- Jul 16, 2019-


According to the Hong Kong Wenhui website, there are many high-rise buildings in Hong Kong. Besides placing sundries on the roof of the building, it can also help protect the environment. A study assessing the development potential of installing solar photovoltaic systems on rooftops of buildings in Hong Kong shows that, if solar photovoltaic systems are fully utilized on rooftops of buildings in Hong Kong, up to about 880 million kilowatt-hours of electricity can be produced annually.

A spokesman for the Hong Kong Electrical and Mechanical Engineering Department (HKEMD) pointed out on the 12th that the installation of solar photovoltaic systems on the rooftops of buildings in Hong Kong is subject to different constraints. For example, about one third of the total rooftop area in Hong Kong has not been effectively installed due to low solar irradiance and other factors. And most of the roof area needs to be used for other purposes, such as fire shelter.

In addition, whether the photovoltaic system can be installed eventually should also consider the structural integrity of the building and the owner's wishes and other factors.

The spokesman said that in order to encourage the development of renewable energy, the SAR Government had taken the lead in allocating funds to install large-scale solar power generation systems in suitable ponds and landfills, and had also implemented a number of renewable energy projects in buildings, sites and community facilities of the SAR Government.
