Ningde, Fujian, China, located at 26.6564° N, 119.5239° E in the Northern Sub Tropics, offers a moderately favorable environment for solar PV energy generation throughout the year. The location experiences varying levels of solar productivity across different seasons, with notable fluctuations in energy output.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 5.44 kWh/day per kW of installed solar capacity. Spring follows as the second-best season, generating 4.06 kWh/day. Autumn sees a slight decrease in output at 3.94 kWh/day, while winter experiences the lowest production at 3.29 kWh/day per kW installed.

The substantial difference between summer and winter outputs highlights the seasonal variability in this region. However, the relatively high productivity during spring and autumn suggests that Ningde maintains decent solar potential for a significant portion of the year.

Optimal Panel Installation

For fixed panel installations in Ningde, Fujian, the ideal tilt angle to maximize year-round solar production is 24 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the location's latitude and the Earth's elliptical orbit.

Environmental Considerations

While Ningde's location is generally favorable for solar energy production, there are some environmental factors to consider:

1. Humidity: The subtropical climate can lead to high humidity levels, potentially affecting panel efficiency.
2. Typhoons: Being in a coastal region, Ningde may experience typhoons, which could pose risks to solar installations.

To mitigate these factors, installers should use corrosion-resistant materials and ensure robust mounting systems capable of withstanding strong winds. Regular cleaning and maintenance can also help combat efficiency losses due to humidity-related issues.

In conclusion, while Ningde faces some challenges, its overall solar potential remains promising. With proper installation techniques and maintenance, solar PV systems in this location can provide substantial energy output throughout the year, particularly during the summer and spring 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 Ningde

Seasonal solar PV output for Latitude: 26.6564, Longitude: 119.5239 (Ningde, 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 24° South in Ningde, China

To maximize your solar PV system's energy output in Ningde, China (Lat/Long 26.6564, 119.5239) throughout the year, you should tilt your panels at an angle of 24° 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 Ningde, 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 Ningde, China. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 24° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
11° South in Summer	30° South in Autumn	42° South in Winter	20° 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 Ningde, 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 Ningde, 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 Ningde, China

The topography around Ningde, China, located at latitude 26.6564 and longitude 119.5239, is characterized by a diverse landscape that includes coastal areas, rolling hills, and mountainous regions. Situated in the eastern part of Fujian Province, Ningde's terrain is a mix of rugged and gentle features that have been shaped by both natural processes and human activity over time. Along the coastline, Ningde boasts numerous bays, inlets, and small islands, creating a picturesque shoreline that stretches for hundreds of kilometers. These coastal areas gradually give way to lowlands and plains, which are often used for agriculture and urban development. As one moves inland, the landscape becomes increasingly hilly, with gentle slopes and valleys interspersed throughout the region. Further from the coast, the terrain becomes more mountainous, with several notable peaks and ranges dominating the landscape. These mountains, part of the larger Wuyi Mountain range system, create a natural barrier between Ningde and the interior regions of Fujian Province. The mountains are often covered in lush vegetation, including forests and bamboo groves, which contribute to the area's rich biodiversity.

Potential Areas for Large-Scale Solar PV

When considering areas near Ningde that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would offer ample sunlight exposure, relatively flat terrain, and minimal environmental impact. The coastal plains and lowlands surrounding Ningde present promising opportunities for solar PV development. These areas typically have fewer obstructions to sunlight and offer larger, contiguous plots of land that could accommodate extensive solar arrays. Additionally, the proximity to existing infrastructure and urban centers could facilitate easier grid connection and maintenance. Some of the gently sloping hillsides in the region could also be suitable for solar PV installations. South-facing slopes, in particular, would receive optimal sunlight throughout the day. However, care must be taken to avoid areas with significant ecological value or those prone to landslides. It's worth noting that while the mountainous regions receive ample sunlight, their steep terrain and often dense vegetation make them less ideal for large-scale solar projects. These areas would require extensive land clearing and present challenges in terms of accessibility and construction. Ultimately, the selection of sites for solar PV development near Ningde would require detailed environmental and feasibility studies. Factors such as local climate patterns, land ownership, and proximity to power transmission infrastructure would all play crucial roles in determining the most suitable locations for these renewable energy projects.
