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.

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.

What factors affect solar energy resources available in Hong Kong?

Two major factors have to be considered when we evaluate solar energy resources available in Hong Kong. The first one is the geographical position: at a latitude of about 22°N, Hong Kong has the Sun shining usually from the south at noon. In general, the amount of radiation increases with the elevation angle of the Sun.

Can solar power help Hong Kong grow?

In 2022, Hong Kong's total electricity consumption was approximately 44.7 TWh. The combined physical potential from rooftops and facades exceeds this figure by more than five times, highlighting the critical role solar energy could play in alleviating energy pressure and fostering sustainable growth.

Can solar farms help Hong Kong transition to a low-carbon future?

This initiative, with the full backing of the Environment and Ecology Bureau and the Environmental Protection Department (EPD), not only provides a sustainable, low-carbon energy solution but also underscores the vast potential for similar solar farms across Hong Kong, supporting the city’s transition to a low-carbon future.

How much solar energy does Hong Kong use?

Hong Kong's roof area, totaling 26.08 km 2, shows a physical potential of approximately 4.00 × 10 13 Wh, reflecting the significant solar energy collection capacity. Similarly, building facades, covering about 330.05 km 2, possess a physical potential of 2.48 × 10 14 Wh. In 2022, Hong Kong's total electricity consumption was approximately 44.7 TWh.
