Solar PV Analysis of Shangrao, China
Shangrao, Jiangxi, China is a fairly good location for generating solar energy throughout the year. The amount of electricity that can be made from each kilowatt of installed solar varies with the seasons. During summer, you can expect to generate about 5.19 kilowatt-hours (kWh) per day and in autumn it drops slightly to around 4.32 kWh/day. Winter sees further decrease with an average generation of about 3.21 kWh/day while springtime production goes up a little bit to approximately 3.57 kWh/day.
The highest energy production is during the summertime because there are more hours of sunlight and less cloud cover generally compared to other seasons which means more sunlight hitting your solar panels and thus more power produced.
For optimal performance at this location, fixed panel installations should ideally be tilted at an angle facing 26 degrees South which helps to maximise total yearly electricity production from these panels by ensuring they are oriented towards the direction where they receive maximum sunlight exposure throughout different times of the year.
However, there could be some local factors that may hinder solar power generation in Shangrao such as periods of heavy rainfall or foggy conditions common in subtropical climates like Shangrao's which could block sunlight from reaching your panels thereby reducing their output.
To mitigate against these potential issues when installing your solar system, consider using high-quality panels that have excellent performance even under less than ideal weather conditions and also ensure regular cleaning/maintenance schedules especially after periods of heavy rain or dust storms so as to keep your panels free from dirt or debris which could lower their efficiency over time if left unchecked.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 319 locations across China. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Shangrao
Seasonal solar PV output for Latitude: 28.4527, Longitude: 117.9451 (Shangrao, 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 26° South in Shangrao, China
To maximize your solar PV system's energy output in Shangrao, China (Lat/Long 28.4527, 117.9451) throughout the year, you should tilt your panels at an angle of 26° 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 Shangrao, 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 Shangrao, China. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 26° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 13° South in Summer | 33° South in Autumn | 44° 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.
Calculate solar panel row spacing in Shangrao, 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 Shangrao, 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 Shangrao, China
Shangrao, China is located in the northeast of Jiangxi Province. The topography around Shangrao is characterized by a mix of mountains, hills, and plains with an elevation ranging from 20 to 1,729 meters. The terrain slopes down from the southwest to the northeast.
The region has a subtropical monsoon climate with plenty of sunshine throughout the year which makes it suitable for solar PV installations. However, due to its varied topography, flat areas would be more suited for large-scale solar PV projects as they provide easier installation and maintenance compared to hilly or mountainous regions.
Areas such as Yanshan County and Guangfeng District which are part of Shangrao city could be potential sites for large scale solar farms due to their relatively flat terrains compared to other parts within this region. Additionally, any unused farmland or industrial zones could also serve as potential locations for large-scale solar PV installations.
However, it's important that before setting up any large-scale project detailed feasibility studies including sunlight availability throughout the year (solar irradiance), land usage rights, impact on local ecology among others need to be conducted.
China solar PV Stats as a country
China ranks 1st in the world for cumulative solar PV capacity, with 306,973 total MW's of solar PV installed. This means that 6.20% of China's total energy as a country comes from solar PV (that's 13th in the world). Each year China is generating 217 Watts from solar PV per capita (China ranks 24th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in China?
Yes, there are several incentives for businesses wanting to install solar energy in China. These include subsidies from the Chinese government, preferential tax policies, and access to low-interest loans. Additionally, businesses may be eligible for renewable energy certificates (RECs) which can be sold on the open market for additional income.
