Solar PV Analysis of Xinzhou, China
Xinzhou, Shanxi, China, situated at 38.4058°N, 112.7022°E in the Northern Temperate Zone, presents a varied landscape for solar energy generation throughout the year. This location experiences distinct seasonal fluctuations in solar output, which significantly impact the effectiveness of photovoltaic (PV) systems.
Seasonal Solar Performance
The solar energy potential in Xinzhou varies considerably across seasons. Summer stands out as the most productive period, with an impressive daily output of 6.16 kWh per kW of installed solar capacity. Spring follows closely, generating 5.77 kWh/day. In contrast, autumn and winter see a notable decrease in production, yielding 3.78 kWh/day and 3.47 kWh/day, respectively.
These figures indicate that Xinzhou experiences a significant solar energy boom during the warmer months, particularly from late spring through early autumn. This period is ideal for maximizing solar energy generation, making it an opportune time for energy-intensive activities or for storing excess energy for use during less productive months.
Optimal Panel Positioning
To achieve maximum year-round solar energy production in Xinzhou, Shanxi, fixed solar panels should be tilted at a 34-degree angle facing south. This optimal angle is calculated based on the location's latitude, solar elevation angles, and daily PV potential, ensuring the panels capture the most sunlight possible throughout the year.
Environmental Considerations
While Xinzhou's location is generally favorable for solar energy production, there are some environmental factors to consider. The region experiences a semi-arid climate, which can lead to dust accumulation on solar panels, potentially reducing their efficiency. Regular cleaning and maintenance of the panels can mitigate this issue.
Additionally, Xinzhou is known for its coal mining industry, which may contribute to air pollution. Particulate matter in the air can slightly reduce solar irradiance reaching the panels. Installing panels at a slight angle and implementing a regular cleaning schedule can help combat this challenge.
Weather-Related Factors
Xinzhou experiences cold winters with occasional snowfall, which can temporarily cover solar panels and reduce their output. Installing panels at the recommended 34-degree angle helps shed snow more easily. Moreover, the use of snow-shedding coatings on panels can further enhance their winter performance.
In conclusion, while Xinzhou faces some challenges for solar energy production, particularly during winter months, its overall solar potential remains promising. With proper installation techniques and regular maintenance, solar PV systems in this location can provide a significant and reliable source of renewable energy throughout the year.

Solar output per kW of installed solar PV by season in Xinzhou
Seasonal solar PV output for Latitude: 38.4058, Longitude: 112.7022 (Xinzhou, 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 34° South in Xinzhou, China
To maximize your solar PV system's energy output in Xinzhou, China (Lat/Long 38.4058, 112.7022) throughout the year, you should tilt your panels at an angle of 34° 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 Xinzhou, 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 Xinzhou, China. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 22° South in Summer | 44° South in Autumn | 54° South in Winter | 31° 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 Xinzhou, 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 Xinzhou, China.
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 Xinzhou, China
The topography around Xinzhou, China is characterized by a diverse landscape that includes both mountainous regions and flatter areas. Xinzhou is situated in the northern part of Shanxi Province, which is known for its rugged terrain and varied elevations.
To the west and northwest of Xinzhou, you'll find the Lüliang Mountains, a significant mountain range that runs north to south. These mountains feature steep slopes and deep valleys, with some peaks reaching heights of over 2,000 meters above sea level. The presence of these mountains creates a natural barrier and influences the local climate.
To the east and southeast, the terrain becomes more gentle, transitioning into the Taiyuan Basin. This area is characterized by rolling hills, plateaus, and some flat plains. The elevation generally decreases as you move eastward, with the landscape becoming more suitable for agriculture and urban development.
The city of Xinzhou itself is situated in a relatively flat area, surrounded by hills and mountains. The Hutuo River flows through the region, carving out valleys and contributing to the area's topographical diversity.
Regarding areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, the flatter regions to the east and southeast of Xinzhou offer the most promising locations. These areas typically have:
- More consistent sunlight exposure due to fewer obstructions from mountains
- Larger, continuous tracts of land that can accommodate extensive solar panel arrays
- Easier access for construction and maintenance of solar facilities
- Proximity to existing infrastructure and power grids
The plains and plateaus of the Taiyuan Basin, extending eastward from Xinzhou, would likely be the most suitable locations for large-scale solar PV projects. These areas offer a good balance of available land, favorable topography, and adequate solar radiation. However, it's important to note that specific site assessments would be necessary to determine the optimal locations, taking into account factors such as local climate conditions, land use regulations, and proximity to power transmission infrastructure.
