Tsim Sha Tsui, Kowloon City, Hong Kong is a pretty good spot for generating energy through solar panels all year round. This is because it's located in the Tropics, where sunlight levels stay fairly consistent throughout the year. The amount of electricity you can expect to generate from each kilowatt of installed solar varies by season - with the most being produced in Summer (5.49kWh/day) and Spring (5.40kWh/day), and slightly less in Autumn (4.95kWh/day) and Winter (4.40kWh/day).
If you're setting up fixed panel installations at this location, it's best to tilt your panels 20 degrees towards the South to get maximum production all year round.
However, there are some factors that could potentially interfere with solar production here. For example, Hong Kong has a wet season which could reduce sunlight exposure on some days due to cloud cover or heavy rainfall. Also, air pollution in urban areas like Tsim Sha Tsui might also affect how much sun reaches your panels.
To overcome these challenges, you can consider installing tracking systems that adjust the angle of your panels throughout the day for optimal sun exposure despite changing weather conditions or seasons. It may also be beneficial to clean your panels regularly to remove any dust or pollutants that might block sunlight.
In conclusion though, even considering these potential obstacles, Tsim Sha Tsui still offers relatively high and consistent solar energy potential throughout most of the year making it a suitable location for solar power generation.
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 47 locations across Hong Kong. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Tsim Sha Tsui
Seasonal solar PV output for Latitude: 22.2944, Longitude: 114.1596 (Tsim Sha Tsui, Hong Kong), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
 
Ideally tilt fixed solar panels 20° South in Tsim Sha Tsui, Hong Kong
To maximize your solar PV system's energy output in Tsim Sha Tsui, Hong Kong (Lat/Long 22.2944, 114.1596) throughout the year, you should tilt your panels at an angle of 20° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Tsim Sha Tsui, Hong Kong
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Tsim Sha Tsui, Hong Kong. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 20° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 6° South in Summer | 28° South in Autumn | 37° South in Winter | 15° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Tsim Sha Tsui, Hong Kong
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Tsim Sha Tsui, Hong Kong.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Tsim Sha Tsui, Hong Kong
Tsim Sha Tsui is located in the southern part of Kowloon Peninsula, Hong Kong. It's a bustling urban area that's largely flat but surrounded by hills to the north and east. The Victoria Harbour lies to its south.
The region is heavily built-up with numerous high-rise buildings, shopping centers, hotels, and cultural facilities. This dense urban environment may not be ideal for large-scale solar photovoltaic (PV) installations due to limited open space and potential shading from surrounding structures.
However, rooftops of these high-rise buildings can be utilized for smaller scale solar PV systems. For larger scale projects, less densely populated areas in New Territories or outlying islands like Lantau Island might be more suitable where there are more open spaces or on hill slopes that receive ample sunlight.
Another consideration would be the International Airport at Chek Lap Kok on Lantau Island which has vast roof surfaces suitable for solar panel installation.
It should also be noted that Hong Kong’s climate is subtropical leading to significant cloud cover and rainfall which could impact the efficiency of solar panels. Therefore any site selection should take into account these factors as well as local regulations regarding land use and renewable energy installations.
