Solar Energy Production in Fuzhou, China

Fuzhou, China, located in the Northern Sub Tropics at coordinates 27.9544, 116.3282, offers reasonably good conditions for solar PV energy generation throughout the year. The seasonal variation in energy production shows a pattern typical of subtropical regions, with higher output during summer months and reduced production in winter. The location experiences its peak solar energy production during summer, generating 5.52kWh per day for each kilowatt of installed solar capacity. This represents nearly twice the winter output, making summer the optimal season for solar energy harvesting in Fuzhou. In the transitional seasons, autumn yields 4.04kWh/day, while spring provides 3.31kWh/day per kW installed. Winter shows the lowest production at 3.09kWh/day, though this is still a usable amount of energy compared to many other regions at similar latitudes.

Optimal Panel Installation

For fixed solar panel installations in Fuzhou, the ideal tilt angle to maximize year-round energy production is 25 degrees facing South. This angle has been calculated to optimize the capture of solar energy across all seasons, accounting for the Earth's elliptical orbit and the specific latitude of this location.

Environmental and Weather Considerations

Several environmental factors may impact solar production in Fuzhou:

• High humidity and frequent rainfall in the subtropical climate can reduce panel efficiency through cloud cover and water accumulation
• Seasonal typhoons that affect southeastern China can damage installations if not properly secured
• Air pollution from nearby industrial activities may deposit particulate matter on panels, reducing their effectiveness
• Summer heat can slightly decrease panel efficiency, as PV panels typically lose efficiency when operating above optimal temperatures

Preventative Measures

To maximize solar energy production in Fuzhou, several measures can be implemented: Installing panels with self-cleaning technologies or applying hydrophobic coatings can help manage the effects of frequent rainfall and humidity. Regular maintenance schedules should include cleaning to remove air pollution deposits. For typhoon resilience, using reinforced mounting systems with wind resistance ratings appropriate for the region is essential. Some installations may benefit from dynamic mounting systems that can be adjusted to a flat position during extreme weather events. To address summer heat issues, ensuring adequate airflow beneath panels through proper mounting designs can help maintain cooler operating temperatures and preserve efficiency. Despite these considerations, Fuzhou's location provides a good balance of solar potential throughout the year, with summer being particularly productive, making it a viable location for solar PV installations with proper planning and preventative measures.

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 Fuzhou, Jiangxi

Seasonal solar PV output for Latitude: 27.9544, Longitude: 116.3282 (Fuzhou, Jiangxi, 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 25° South in Fuzhou, Jiangxi, China

To maximize your solar PV system's energy output in Fuzhou, Jiangxi, China (Lat/Long 27.9544, 116.3282) throughout the year, you should tilt your panels at an angle of 25° 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 Fuzhou, Jiangxi, 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 Fuzhou, Jiangxi, China. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 25° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
12° South in Summer	32° South in Autumn	43° South in Winter	21° 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.

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 Fuzhou, Jiangxi, 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 Fuzhou, Jiangxi, China

The topography around Fuzhou in Jiangxi Province, China presents a diverse landscape characterized primarily by mountains, hills, and river valleys. This inland city (not to be confused with the more well-known coastal Fuzhou in Fujian Province) is situated in a region where the terrain transitions from the mountainous areas in the east to the more open valleys in the west.

Mountain and Hill Systems

Fuzhou is nestled within the broader geographical context of southeastern China's mountain systems. The area features extensions of the Wuyi Mountain range, with numerous peaks and ridges creating a rugged landscape. These mountains generally run in a northeast to southwest direction, creating valleys between them that have historically served as important transportation corridors. The elevation varies considerably throughout the region, with mountain peaks reaching several hundred meters above sea level, while the valley floors where human settlement is concentrated are significantly lower. This mountainous character means that flat land is at a premium in the immediate vicinity of Fuzhou.

River Systems and Valleys

The Fuzhou area is part of the broader Yangtze River basin, with local waterways eventually feeding into this major river system. Smaller rivers and streams have carved valleys through the mountainous terrain, creating ribbons of relatively flat land that have traditionally been used for agriculture and settlement. These river valleys represent some of the few extensive flat areas in an otherwise hilly to mountainous region. The valleys typically have alluvial soils that have accumulated over centuries, making them fertile grounds for agriculture.

Potential for Solar PV Development

When considering areas suited for large-scale solar photovoltaic development near Fuzhou, several factors related to topography must be considered: The south-facing slopes of hills and mountains present opportunities for solar installation, as they receive more direct sunlight throughout the year in the Northern Hemisphere. These inclined surfaces can sometimes produce better yields than flat terrain, although installation costs may be higher. The river valleys, particularly those with wider flat sections that aren't prime agricultural land, offer potential for larger contiguous solar installations. These areas benefit from being relatively flat, which simplifies construction and maintenance of solar arrays.

Optimal Areas for Solar Development

The most promising areas for large-scale solar PV development near Fuzhou would likely include: The broader, open valleys to the west of the city, where the terrain begins to flatten out, offer significant potential. These areas combine reasonable solar exposure with less challenging terrain for construction. Gently sloping hillsides that face south or southwest, particularly those that aren't heavily forested or used for agriculture, represent good opportunities. The natural inclination of these slopes can improve solar capture efficiency. Abandoned or less productive agricultural land in the river valleys could be repurposed for solar farms without competing with critical food production. Areas where deforestation has already occurred might be suitable for solar development, though environmental impacts should be carefully considered.

Topographical Challenges

The mountainous nature of much of the region does present challenges for solar development. Steep slopes are difficult and expensive to build on, and may suffer from shading issues as surrounding peaks block sunlight during parts of the day. The region also experiences a monsoonal climate with significant rainfall, which can cause soil erosion on slopes where vegetation has been cleared for solar installations. This necessitates careful site selection and engineering to ensure the sustainability of any large-scale solar projects. In conclusion, while the topography around Fuzhou presents certain challenges for solar PV development due to its predominantly mountainous character, there are still substantial opportunities in the river valleys and on appropriate hillsides. The key to successful large-scale solar implementation would be careful site selection that balances solar exposure, land suitability, and environmental considerations.
