Solar PV Analysis of Sheung Shui, Hong Kong
The location at Sheung Shui, Hong Kong is generally a good place for generating solar energy throughout the year. Since it's located in the Tropics where sunlight is consistent most of the time, it makes sense to use solar panels here. The amount of electricity that can be produced from each kilowatt (kW) of installed solar varies by season: you can expect about 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.
This means that during summer and spring are probably the best times for generating solar power at this location because there's more sunlight available compared to autumn and winter.
However, if you're planning on installing fixed-panel solar installations here, it would be ideal to tilt them at an angle of 21 degrees facing South to maximize their productivity all year round.
As far as environmental or weather factors go which could impede solar production at this location - Hong Kong does have a rainy season which typically occurs between April and September when rainfall is heavy and frequent due to monsoons and typhoons; these conditions might reduce how much electricity your panels generate during those periods because less sunlight will reach them when it's cloudy or raining.
However, despite these challenges there are measures one can take when installing their panels that might help ensure greater energy production even during these less-than-ideal conditions:
1) Regular maintenance like cleaning off any dirt or debris from your panels will allow maximum light absorption.
2) Installing a tracking system so your panels follow the sun across the sky could increase their exposure.
3) Using high-quality equipment with better efficiency rates may also help make up for lost output during cloudy days.
4) Finally having a reliable energy storage solution like batteries can store excess power generated on sunny days which then can be used on less sunny or rainy days.
Remember, while these measures might help increase your solar panel's productivity, they will also likely increase the overall cost of your system. So it's important to consider both the benefits and costs when deciding whether to install solar panels at this location.
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 Sheung Shui
Seasonal solar PV output for Latitude: 22.5168, Longitude: 114.1149 (Sheung Shui, 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 21° South in Sheung Shui, Hong Kong
To maximize your solar PV system's energy output in Sheung Shui, Hong Kong (Lat/Long 22.5168, 114.1149) throughout the year, you should tilt your panels at an angle of 21° 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 Sheung Shui, 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 Sheung Shui, Hong Kong. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 21° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 7° South in Summer | 28° South in Autumn | 38° 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 Sheung Shui, 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 Sheung Shui, 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 Sheung Shui, Hong Kong
Sheung Shui, Hong Kong is located in the New Territories region and it's characterized by a mixture of flatlands, hills, and developed areas. The region has both urbanized areas with high-rise buildings and rural areas with farmland.
As for the suitability for large-scale solar PV installations:
1. Open Flat Areas: Large open flat spaces such as unused lands or farmlands could be suitable for ground-mounted solar panels. Sheung Shui was traditionally an agricultural area so there may be potential here if any land is still undeveloped.
2. Rooftops: Given that Hong Kong is densely populated with many high-rise buildings, rooftop solar installation could also be an option to consider especially in commercial or industrial districts.
3. Water Reservoirs: Solar panels can also be installed on water bodies like reservoirs using floating photovoltaic systems (FPV). There are several reservoirs near Sheung Shui which may have potential for this kind of installation.
4. Hill Slopes: While hill slopes are generally not ideal due to shading issues and difficulty of installation, they can still potentially host solar panels if appropriately oriented towards the sun and if the slope isn't too steep.
However, it's important to note that large-scale solar panel installations require comprehensive planning taking into account local regulations, environmental impact assessments, grid connection feasibility etc., apart from just topographical considerations.
