Solar Pole Lights in Hong Kong


Located on China’s southern coast 60 km east of Macau, on the east side of the mouth of the Pearl River estuary, Hong Kong is a metropolitan area and special administrative region of China. Originally a sparsely populated area of farming and fishing villages, the territory has become one of the world’s most significant financial centres and commercial ports. With over 7.5 million residents of various nationalities in a 1,104-square-kilometre territory, Hong Kong
is one of the most densely populated places in the world.

According to data from Hong Kong’s Highways Department (HyD) there are over one hundred and forty thousand pole lights along the roads of Hong Kong. These have to be constantly maintained to ensure they perform reliably. In an effort to reduce carbon emissions and save energy, the Highways Department has been upgrading all existing lamps with LED since launching the LED public lighting replacement programme in 2017.

LED and Solar Pole Lights are the future of city lighting

LED lighting has proven to be the lamp and light source of the future. With an urgent need for cities to reduce their energy needs and in turn their carbon footprint and reliance on fossil fuel, new solutions are needed. Street lighting was the precursor to the electricity grid and it is poetic to see that street lighting may also be the catalyst for the next societal shift in how cities are planned and built. 

Energy Independence through off grid Solar Pole Lights

The Hong Kong government and Highways Department (HyD) have already recognised a need for innovation through their LED public lighting replacement program. Replacing high pressure sodium lamps (HPS), ceramic metal halide discharge lamps (CDM), or high efficiency fluorescent lamps with LED not only reduces energy costs and carbon footprint, the extended maintenance and replacement times also provide a more economically and environmentally sustainable solution. 

The next logical step in this evolution is the integration of solar pole lights. Their ability to generate their own electricity from available sunlight alleviates the power load on the existing electricity grid, as well as freeing the pole lights from the cost associated with cabling and
on-grid energy prices.

Why is the Solar Pole Lights solution?

Let's know more about why the solar pole light is necessary.


When and why did Hong Kong's Highways Department initiate the LED replacement programme?

: The programme was launched in 2017 to make public lighting more sustainable, use less energy, and reduce maintenance costs.

What benefits do solar pole lights provide?
: Solar pole lights are independent of the electricity grid, freeing them from costs and maintenance issues associated with on-grid lighting. 
How many hours average sunlight does Hong Kong receive each year.

: Hong Kong receives on average 1964 hours of sunlight per year (of a possible 4383)
