Solar PV Analysis of Man Kok, Hong Kong
The location at Man Kok, Hong Kong, is quite suitable for generating energy via solar photovoltaic (PV) panels year-round. This is because it's located in the Tropics where sunlight is consistent throughout most of the year. The amount of energy you can expect to generate from each kilowatt (kW) of installed solar varies by season: 5.49 kilowatt-hours (kWh) per day in Summer, 4.95 kWh/day in Autumn, 4.40 kWh/day in Winter and 5.40 kWh/day in Spring.
To maximize total yearly production from your solar PV system at this location, you should tilt your panels at an angle of 20 degrees towards the South if they are fixed.
Now let's look at times when generating solar energy might be more ideal here. Given that summer and spring have higher daily averages (5.49 and 5.40 kWh/day respectively), these would be the best seasons for generation as compared to winter or autumn.
However, there may also be local environmental or weather factors that could affect how much energy you can generate with your solar panels here.
For instance, if this area has a lot of buildings or trees that cast shadows on your panels during parts of the day, this could reduce their output significantly - especially during winter when days are shorter and shadows longer.
Similarly, if Man Kok tends to get a lot of foggy or cloudy days throughout certain times of year - again particularly during winter - this could also lower how much electricity you're able to produce with your PV system.
You may also need to consider any local regulations about installing solar panels on buildings or homes here; some places have rules about where and how these systems can be installed which could affect their efficiency too.
In terms of preventing potential issues like these from impacting your system's performance too much:
- You might want to consider trimming back any nearby trees or bushes that could cast shadows on your panels.
- If fog or clouds are a common issue, you might want to consider installing your panels in a location where they're less likely to be affected - such as on an elevated structure or hillside.
- Finally, always make sure to check and follow any local regulations about solar panel installation.
In conclusion, while there may be some potential issues to consider and address, Man Kok's consistent sunlight throughout most of the year makes it a generally good location for solar energy production.
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 Man Kok
Seasonal solar PV output for Latitude: 22.3157, Longitude: 114.159 (Man Kok, 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 Man Kok, Hong Kong
To maximize your solar PV system's energy output in Man Kok, Hong Kong (Lat/Long 22.3157, 114.159) 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 Man Kok, 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 Man Kok, 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 Man Kok, 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 Man Kok, 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 Man Kok, Hong Kong
Man Kok is located in the northeastern part of Hong Kong, near the border with mainland China. The topography of this area is characterized by hills and mountains, with some flat areas along the coast and river valleys. There are also forests and agricultural land in this region.
For large-scale solar PV installations, flat or gently sloping areas are generally most suitable as they can accommodate larger arrays of solar panels. Therefore, coastal areas or valley floors around Man Kok could potentially be good locations for such installations. However, it's important to note that these areas would need to be free from significant shading (from mountains or tall buildings) for a substantial part of the day to maximize solar energy production.
In addition to topography, other factors like local climate conditions (amount of sunlight), land use regulations, proximity to power grids and infrastructure would also need to be considered when identifying suitable sites for large-scale solar PV installations.
Lastly, it's worth noting that Hong Kong has been promoting rooftop solar PV systems due its limited land space. Many commercial buildings in urban parts have installed such systems on their rooftops.
