Jingmen, Hubei, China, located at latitude 31.0356 and longitude 112.2088, offers a moderately favorable environment for solar PV energy generation throughout the year. This location in the Northern Sub Tropics experiences varying levels of solar productivity across the four seasons.

Seasonal Solar Performance

Summer stands out as the peak season for solar energy production, with an impressive 4.87 kWh per day for each kilowatt of installed solar capacity. Spring and autumn follow closely, yielding 3.86 kWh/day and 3.78 kWh/day respectively. Winter sees a noticeable dip in production, generating 2.93 kWh/day, which is still a respectable output considering the shorter days and lower sun angle during this season.

The most ideal time for solar energy generation in Jingmen is from late spring through early autumn. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency and energy output.

Optimal Panel Installation

For fixed panel installations in Jingmen, Hubei, the ideal tilt angle to maximize year-round solar production is 28 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun positions across seasons.

Environmental Considerations

While Jingmen's climate is generally conducive to solar energy production, there are some environmental factors to consider:

• Seasonal monsoons: Heavy rainfall during the summer monsoon season may temporarily reduce solar efficiency.
• Air pollution: Industrial activities in the region can lead to increased particulate matter in the air, potentially affecting solar panel performance.

To mitigate these factors, consider implementing the following measures when installing solar panels:

• Use self-cleaning panels or schedule regular cleaning to combat dust and pollution buildup.
• Install panels at a slightly steeper angle to promote natural cleaning during rainfall.
• Employ high-quality, weather-resistant panels to withstand varying climate conditions.

Overall, Jingmen presents a good location for solar PV energy generation, with strong potential during summer months and reasonable output year-round. With proper installation and maintenance, solar energy can be a reliable and efficient power source in this region.

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

Seasonal solar PV output for Latitude: 31.0356, Longitude: 112.2088 (Jingmen, 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 28° South in Jingmen, China

To maximize your solar PV system's energy output in Jingmen, China (Lat/Long 31.0356, 112.2088) throughout the year, you should tilt your panels at an angle of 28° 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 Jingmen, 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 Jingmen, China. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 28° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
15° South in Summer	36° South in Autumn	46° South in Winter	24° 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 Jingmen, 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 Jingmen, 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 Jingmen, China

The topography around Jingmen, China, located at latitude 31.0356 and longitude 112.2088, is characterized by a diverse landscape that includes both flat plains and rolling hills. This region is part of the Jianghan Plain, which is a vast expanse of lowland situated in central China's Hubei Province. The area surrounding Jingmen features a mix of agricultural land, urban development, and scattered patches of forested hills. To the north and east of Jingmen, the terrain is predominantly flat, with extensive farmland and occasional small water bodies. This flat terrain gradually transitions into gently undulating hills as one moves towards the south and west. These hills, while not particularly high, provide some variation to the otherwise level landscape. The region is also marked by the presence of several rivers and streams, including the Han River, which flows to the north of Jingmen. These waterways have played a significant role in shaping the local topography over time, creating fertile alluvial plains and occasional floodplains along their banks.

Areas Suitable for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Jingmen, the flat plains to the north and east of the city present the most promising opportunities. These areas offer several advantages for solar energy development: Firstly, the level terrain of the plains provides ample space for the installation of large solar arrays without the need for extensive land preparation or grading. This flat landscape also minimizes shading issues between solar panels, allowing for optimal sun exposure throughout the day. Secondly, many of these areas are already used for agriculture, which could potentially allow for dual-use solar farms that combine energy production with crop cultivation or grazing. This approach, known as agrivoltaics, can maximize land use efficiency and provide additional income for local farmers. Additionally, the proximity to existing infrastructure, including roads and power transmission lines, makes these areas more economically viable for large-scale solar projects. The relatively close distance to urban centers like Jingmen itself ensures that the energy produced can be easily distributed to areas of high demand. While the hilly regions to the south and west may be less suitable for expansive solar farms due to their uneven terrain, they could still accommodate smaller-scale installations or be utilized for other renewable energy projects, such as wind power. It's important to note that any large-scale solar development would need to carefully consider environmental impacts, land use regulations, and the potential effects on local communities and ecosystems. Proper planning and stakeholder engagement would be crucial to ensure the successful and sustainable implementation of solar PV projects in the region.
