Chuzhou, Anhui, China, located at latitude 32.3216 and longitude 118.2933 in the Northern Sub Tropics, presents a reasonably favorable location for solar PV energy generation throughout the year. The solar electricity output varies seasonally, with the highest production occurring during summer months.
Seasonal Solar Production
Solar panels in Chuzhou demonstrate good performance across all seasons, though with notable seasonal variations. Summer yields the highest daily output at 4.88kWh per kW of installed capacity, followed by spring with 4.49kWh/day. Autumn produces a moderate 3.89kWh/day, while winter shows the lowest output at 3.07kWh/day.
This seasonal pattern indicates that Chuzhou experiences its peak solar generation potential from late spring through early autumn, making this roughly five-month period particularly advantageous for solar energy production. The relatively modest decline in winter output suggests that solar remains viable year-round, though with reduced efficiency during the colder months.
Optimal Panel Installation
For fixed solar panel installations in Chuzhou, Anhui, the ideal tilt angle to maximize year-round energy production is 29 degrees facing South. This carefully calculated angle optimizes the annual solar harvest by balancing seasonal variations in the sun's position throughout the year.
Environmental Considerations
Several environmental factors could potentially impact solar production in Chuzhou:
- Seasonal monsoon rains and humidity, particularly during summer, may occasionally reduce panel efficiency through cloud cover and moisture accumulation
- Air pollution from nearby industrial areas could deposit particulate matter on panels, reducing light transmission
- Occasional dust storms from northern China might affect panel cleanliness
To mitigate these challenges, solar installations in Chuzhou should incorporate regular cleaning schedules, especially after dusty periods or extended dry spells. Anti-soiling coatings can help reduce dust accumulation, while slightly increasing the tilt angle beyond the optimal 29 degrees may improve self-cleaning from rainfall. Additionally, quality inverters with good partial shading tolerance can help maintain efficiency during cloudier periods.
Overall, Chuzhou offers a good location for solar PV deployment with consistent year-round production, particularly strong during the warmer months, making it an attractive site for renewable energy investment when proper installation practices are followed.

Ideally tilt fixed solar panels 29° South in Chuzhou, China
To maximize your solar PV system's energy output in Chuzhou, China (Lat/Long 32.3216, 118.2933) throughout the year, you should tilt your panels at an angle of 29° 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 Chuzhou, 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 Chuzhou, China. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 29° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 16° South in Summer | 37° South in Autumn | 48° South in Winter | 25° 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 Chuzhou, 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 Chuzhou, 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 Chuzhou, China
The region surrounding Chuzhou, located in eastern China's Anhui Province, features predominantly flat to gently rolling terrain characteristic of the North China Plain. This area sits within the lower reaches of the Yangtze River basin, with an average elevation of approximately 20-50 meters above sea level. The landscape is primarily composed of alluvial plains formed by the Yangtze River and its tributaries over millennia, creating fertile lands that have historically supported extensive agricultural activity.
Topographical Features
The immediate vicinity of Chuzhou is dominated by lowland plains with occasional low hills rising from the otherwise level landscape. To the north and east, the terrain maintains its relatively flat character as it extends toward Jiangsu Province. The southern portions of the region see a gradual transition to more varied topography, with scattered hills becoming more prominent as one moves toward the Dabie Mountains further to the southwest. Several water bodies influence the local geography, including the Huai River which flows through the northern part of the region. This river system, along with numerous smaller tributaries and canals, has shaped the landscape through centuries of natural processes and human modification. These waterways create natural divisions in the terrain and have historically served as important transportation routes.Soil and Surface Conditions
The soils around Chuzhou are predominantly alluvial in nature, consisting of silts and clays deposited by river systems. These soils are generally deep and fertile, which has made the region an important agricultural center. In some areas, particularly where hills rise from the plains, the soil composition changes to include more loam and occasionally rocky substrates.Solar PV Potential Areas
For large-scale solar photovoltaic development, several areas near Chuzhou present favorable conditions. The most suitable locations would be: The elevated plateaus and gentle slopes to the south and southwest of the city offer promising sites for solar installations. These areas typically experience less seasonal flooding than the lower plains and provide good drainage conditions. The slight elevation can also reduce the impact of morning fog that sometimes affects the lower-lying areas. The northeastern plains extending toward Jiangsu Province represent another potential zone for solar development. These areas feature extensive flat terrain with minimal shading obstacles, allowing for efficient arrangement of solar arrays. The land here is less intensively cultivated in some sections, potentially reducing competition with agricultural uses. Several areas of reclaimed or less productive agricultural land scattered throughout the region could be repurposed for solar installations without significantly impacting food production. These parcels often have existing access to transportation infrastructure, which would facilitate construction and maintenance of solar facilities.Topographical Challenges
Despite the generally favorable terrain, certain topographical factors require consideration for solar development. The region experiences seasonal monsoon conditions, with significant rainfall during summer months. This necessitates careful site selection to avoid areas prone to flooding or water accumulation, particularly in the lowest-lying sections of the plains. The silty soil composition in some areas may require additional foundation engineering to ensure the stability of mounting structures for solar panels. In the hillier sections, careful site assessment would be needed to balance the advantages of elevation against potential challenges related to accessibility and construction costs. Overall, the predominantly flat to gently rolling topography around Chuzhou provides numerous potentially suitable locations for large-scale solar PV development, with the most promising sites found on slightly elevated areas and less productive agricultural lands throughout the region.China solar PV Stats as a country
