Liuzhou, Guangxi, China, situated in the Northern Sub Tropics at coordinates 24.3241, 109.3975, presents a moderate opportunity for solar energy generation throughout the year. The location's potential for solar photovoltaic (PV) energy production varies significantly across seasons, with summer being the most productive period.

Seasonal Solar Output

Summer stands out as the peak season for solar energy generation in Liuzhou, Guangxi, with an impressive daily output of 5.64 kWh per kW of installed solar capacity. This high yield is due to longer daylight hours and more direct sunlight during this time of year.

Autumn follows as the second most productive season, generating 4.20 kWh per day for each kW of installed capacity. While less productive than summer, autumn still offers substantial solar energy potential.

Winter and spring in Liuzhou show similar, albeit lower, solar energy production levels. Winter yields 3.13 kWh per day, while spring produces slightly less at 3.07 kWh per day per kW of installed capacity. These seasons experience shorter daylight hours and less direct sunlight, resulting in reduced solar energy generation.

Optimal Panel Positioning

To maximize year-round solar energy production in Liuzhou, Guangxi, fixed solar panels should be tilted at an angle of 21 degrees facing south. This optimal angle ensures the panels capture the most sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.

Environmental Factors and Mitigation

Liuzhou's climate presents some challenges for solar energy production. The region experiences a monsoon-influenced humid subtropical climate, which can impact solar panel efficiency. High humidity levels and frequent cloud cover, especially during the rainy season from April to August, may reduce solar energy output.

To mitigate these environmental factors, consider the following measures when installing solar panels in Liuzhou:

• Use high-quality, weather-resistant solar panels designed to perform well in humid conditions
• Implement a regular cleaning schedule to remove dust and debris, which can accumulate more quickly in humid environments
• Install a robust mounting system to withstand potential strong winds during monsoon seasons
• Consider adding a solar tracking system to maximize energy capture during periods of limited sunlight

By addressing these environmental challenges and optimizing panel placement, solar energy systems in Liuzhou can still achieve significant energy production, particularly during the summer and autumn months.

Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Solar output per kW of installed solar PV by season in Liuzhou

Seasonal solar PV output for Latitude: 24.3241, Longitude: 109.3975 (Liuzhou, China), 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 Liuzhou, China

To maximize your solar PV system's energy output in Liuzhou, China (Lat/Long 24.3241, 109.3975) 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 Liuzhou, China

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 Liuzhou, China. 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
9° South in Summer	28° South in Autumn	40° South in Winter	17° 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 Liuzhou, China

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 Liuzhou, China.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Liuzhou, China

Liuzhou, situated in southern China's Guangxi Zhuang Autonomous Region, is characterized by a diverse and complex topography. The city itself is nestled in a basin surrounded by karst mountains, creating a picturesque landscape of limestone peaks, caves, and sinkholes. The Liujiang River meanders through the city, adding to its scenic beauty and playing a crucial role in the region's geography. The surrounding area features a mix of low-lying plains, rolling hills, and steep mountain ranges. To the north and east of Liuzhou, the terrain becomes increasingly mountainous, with elevations rising sharply. These mountains are part of the larger Nanling mountain range, which stretches across several provinces in southern China. The southern and western parts of the region are generally flatter, with more extensive areas of level ground and gentler slopes.

Potential for Solar PV Development

When considering areas suitable for large-scale solar photovoltaic (PV) installations near Liuzhou, several factors come into play. The ideal locations would be relatively flat, receive ample sunlight, and have minimal obstructions from natural features or human settlements. The plains and gently rolling hills to the south and southwest of Liuzhou offer the most promise for solar PV development. These areas typically have more open space and fewer steep slopes, making them easier to develop and maintain. The relatively flat terrain also reduces the risk of shading from nearby landforms, ensuring maximum sun exposure throughout the day. Some specific regions that might be suitable include the outskirts of Liuzhou County and parts of Luzhai County to the south. These areas have a mix of agricultural land and less developed spaces that could potentially be repurposed for solar farms. However, it's important to note that the region's frequent cloud cover and occasional heavy rainfall may impact the overall efficiency of solar installations. Additionally, any large-scale solar projects would need to carefully consider their environmental impact, particularly in areas with sensitive karst ecosystems or valuable agricultural land. While the mountainous areas to the north and east may seem less suitable due to their rugged terrain, some of the broader valleys or plateaus within these regions could also be considered for smaller-scale solar installations. These might be particularly useful for providing renewable energy to more remote communities in the highlands. Ultimately, detailed site surveys and environmental impact assessments would be necessary to determine the most appropriate locations for large-scale solar PV projects in the Liuzhou area. These studies would need to balance the region's energy needs with preservation of its unique landscape and ecosystems.
