Hong Kong rooftop solar power station

Is rooftop PV system a viable development option in Hong Kong?

This paper presents an in-depth investigation into the development potential of rooftop PV system in Hong Kong and its environmental benefits as well. The potential installation capacity of rooftop PV systems is estimated to be 5.97 GW p, and the annual potential energy output is predicted to be 5981 GWh accordingly.

How much energy does a rooftop PV system produce in Hong Kong?

After deducting the array distance, the potential installation capacity of rooftop PV systems on all PV-suitable rooftops was estimated to be 5.97 GW p and accordingly the annual potential energy output was predicted to be 5981 GWh. This accounted for 14.2% of the total electricity used in Hong Kong in 2011.

What is a roof PV system in Hong Kong?

Roof PV systems in Hong Kong typically utilize monocrystalline silicon PV modules, known for their high efficiency, stable performance, and aesthetic appeal. The STP260S model (1640 mm × 992 mm), a commonly used monocrystalline silicon module, serves as an example in this study.

What is the potential solar-suitable rooftop area in Hong Kong?

Based on the modified solar-architectural rules of thumb, the potential PV-suitable rooftop area in Hong Kong was estimated to be 54 km 2. To avoid the negative effect of partial shading from front rows on back rows of PV modules, an array distance of 514 mm should be reserved in real Hong Kong project.

Is Hong Kong a good place to install solar panels?

Dr Charles Wong Man-sing (left) and Dr Vivien Lu Lin Hong Kong's abundant solar energy and rooftop capacity are ideal for solar photovoltaic energy generation, a PolyU study has found. Solar panels with different energy conversion efficiency can be integrated into buildings without taking up additional land space.

How many rooftops are suitable for PV panels in Hong Kong?

Using high-resolution airborne laser scanning data and geographical information systems data to map the available rooftop area in Hong Kong, researchers also found that out of the 309,000 buildings, 233,000 are suitable for installing PV panels with a total area of 39 km 2.
