What is Hong Kong's largest solar energy generation project?

It will be Hong Kong’s largest solar energy generation project when complete. The system will generate up to 3 million units (kWh) of electricity each year - equivalent to the annual electricity consumption of more than 900 three-member households in Hong Kong 1, and reduce 1.5 million kg of carbon emission per annum over a 25 year period.

Can building-integrated solar PV systems help Hong Kong achieve a low-carbon future?

These projections account for 12.68%–16.32% of Hong Kong's total electricity consumption in 2022. This study underlines the substantial role of building-integrated solar PV systems in Hong Kong's transition towards a low-carbon future, offering valuable insights for policymaking and implementation strategies.

Can photovoltaic solar panels be installed in Hong Kong?

“Due to the high land price in Hong Kong, it is impossible to mount photovoltaic solar panels on the ground as in mainland China,” says Professor Yang Hong-xing from the Department of Building Environment and Energy Engineering of PolyU, who has been conducting research on renewable energy applications for more than 30 years.

Can PV technology expand the scope of solar energy generation in Hong Kong?

These innovative applications of PV technology present an opportunity to broaden the scope of solar energy generation in Hong Kong. As the city explores ways to diversify its energy sources, the integration of PV technology across various sectors offers a strategic pathway to augment the city's renewable energy matrix.

What are the different types of photovoltaic systems in Hong Kong?

Photovoltaic systems in Hong Kong can be classified into two main types - stand-alone systems and grid-connected systems. These can further be divided into ordinary photovoltaic systems and building-integrated photovoltaic (BIPV) systems.

What are the opportunities for PV technology in Hong Kong?

The opportunities for PV technology in Hong Kong, however, extend well beyond BIPV. Innovative applications such as floating PV systems make use of water bodies, avoiding the land constraints of a densely populated city. These systems can reduce water evaporation and improve panel efficiency through the cooling effect of the water.
