Solar PV Analysis of Kowloon Bay, Hong Kong
Kowloon Bay, Kwun Tong, located in Hong Kong, is an excellent site for solar photovoltaic (PV) power generation due to its geographical position and climate. The average daily energy production per kilowatt of installed solar capacity varies by season: 5.49 kWh in the summer, 4.95 kWh in the autumn, 4.40 kWh in the winter, and 5.40 kWh in the spring.
Situated within tropical latitudes (22.3327° N, 114.2116° E), Kowloon Bay experiences a relatively consistent amount of sunlight throughout the year; this consistency makes it an advantageous location for harnessing solar energy on a year-round basis.
The local climate is characterized more by wet and dry periods than significant temperature fluctuations; therefore there are no substantial weather-related hindrances to solar power generation here.
For optimal results from fixed-panel installations at this location, panels should be tilted at an angle of 20 degrees facing southwards to capture maximum sunlight throughout each day.
However, it's important to note that while Kowloon Bay doesn't face any major environmental or topographical obstacles that would significantly impede solar production overall - such as excessive cloud cover or mountainous terrain - occasional typhoons could potentially damage installations if not properly secured and protected against such events.
Therefore precautions should be taken during installation to ensure panels are robustly mounted with sturdy materials capable of withstanding high wind speeds associated with these weather events; this will help safeguard your investment and ensure a higher level of energy production reliability over time.
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 Kowloon Bay
Seasonal solar PV output for Latitude: 22.3327, Longitude: 114.2116 (Kowloon Bay, 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 Kowloon Bay, Hong Kong
To maximize your solar PV system's energy output in Kowloon Bay, Hong Kong (Lat/Long 22.3327, 114.2116) 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 Kowloon Bay, 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 Kowloon Bay, 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 Kowloon Bay, 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 Kowloon Bay, 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 Kowloon Bay, Hong Kong
Kowloon Bay is located in the eastern part of Hong Kong, and its topography consists mainly of hilly terrain. The area is mostly flat near the bay itself, with some hills rising up to the west and south. The nearby areas that would be most suited for large-scale solar PV are those that have good access to sunlight and minimal shading from trees or buildings. Areas such as Kwun Tong, Tseung Kwan O, and Sai Kung are all relatively flat and open with plenty of sunlight throughout the day. Additionally, these areas are also close enough to Kowloon Bay that they can easily be connected to it via transmission lines.
