From our previous study [19], the greatest annual solar-radiation in Hong Kong lies in the quadrant between the south and the west directions. Hence both the south and west facades of the residence are proposed for accommodating the solar-collector arrays. The make-up potable water is to come from the nearby cold potable-water storage tank
Tai Hang Tung Stormwater Storage Tank (THTST) is the first and largest underground stormwater storage tank in Hong Kong, located underneath the rugby pitch and one of the football pitches in Tai Hang Tung Recreation Ground. The tank is 136 metres long, 130 metres wide and 7.5 metres deep internally, with a storage capacity of 100,000 cubic
The Happy Valley Underground Stormwater Storage Scheme (HVUSSS) is an important flood prevention project of the Drainage Services Department, aiming to relieve the flooding risks in the Happy Valley and Wai Chai areas. In addition to the underground stormwater storage tank with a capacity to withstand a rainstorm of a return period of 1 in 50 years, the project includes above
Owners and/or property management companies should refer to the Handbook on Design, Operation and Maintenance of Solar Photovoltaic Systems published by the Electrical and Mechanical Services Department and arrange regular annual inspections and routine maintenance for the PV systems including their supporting structures.
The result indicates that solar water heating systems can work effectively in Hong Kong and that significant energy savings can be achieved. Systems with smaller storage tanks and smaller solar collector areas will have slightly lower performance than the 250-litre system, as small tanks usually have higher loss per unit storage volume.

Compact and light compared with traditional alternatives, these cutting-edge energy storage systems are ideal for applications with a high energy demand and variable load profiles, accounting for both low loads and peaks.They can work standalone and synchronized, as the heart of decentralized hybrid systems with several energy inputs, like the grid, power
At the conclusion of our tank inspection services, and should repairs be needed, our experts provide a recommended repair plan. If repairs are made then our personnel can re-inspect the affected asset, providing a supplemental report of the findings. As above-ground storage tank assets age, extending their safe operating cycle becomes more

• Hong Kong Electrical Contractors'' Association Ltd • Hong Kong Housing Authority 2.4 Thermal Storage Tanks (1) A solar water heating system generally requires a well-insulated thermal storage tank to hold the heated water. The thermal storage tank is often equipped with an auxiliary electric heater (or gas heater) to
In Hong Kong, there is a good application potential for the centralized solar water-heating systems in new multi-storey residential developments. With a high density of tall buildings, it is more viable to take advantage of the vertical surfaces of
Traditionally, the system includes a thermal energy storage tank situated between the solar collector field and the chiller generator, or a chilled water storage tank located between the chiller and the load. At the University of Hong Kong campus, Yeung et al. [110] have presented a detailed description of a solar-powered absorption air
The results obtained indicated that Hong Kong basalt is the optimal candidate for high-temperature thermal energy storage material, with 850 °C identified as the suitable maximum working temperature. Other igneous rocks from Hong Kong can be utilized for mid-to-low temperature range (100–500 °C) thermal energy storage engineering.

The solar insolation is 18,980 MJ/yr for the 4m2 collector, hence giving an efficiency of 43% for the solar water heating installation, taking into account of auxiliary power. The results indicate that solar water heaters work effectively in Hong Kong and that significant energy savings can be achieved.
Evacuated tube solar water heaters are increasingly in use in Hong Kong because of their good thermal efficiency and high water temperature achievable as compared to the flat-plate solar water heaters. But so far their thermal performance has not been systematically evaluated and therefore not well known to the users.
There are plenty of solar thermal technologies products available in the market. Solar thermal products sold in Hong Kong are either imported from overseas countries such as Australia, Israel, USA or from the Mainland. Since there are many products available in the local market, prices are becoming competitive in recent years.
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.
The planned construction period is about 18 months, commencing in Q1 2025. Binnies Director of Projects Justin Searle said: “The development of large-scale solar farms is new to Hong Kong and it’s exciting to be at the forefront of several new initiatives, including floating solar on reservoirs and also land-based systems on closed landfills.
Solar irradiation data of Hong Kong is available from the Hong Kong Observatory. The data for the daily mean horizontal solar irradiation for each month of the year is given in the Solar Water Heating - Resource Potential section.
