Solar PV Analysis of Shangqiu, China
Located at 34.4515 latitude and 115.6479 longitude, Shangqiu in China is a promising site for the installation of solar photovoltaic (PV) systems given its favorable climatic conditions. This region experiences long summer days with abundant sunshine that enhances solar energy generation, with an average yield of about 5.14 kWh per day for each kW of installed solar capacity during this season.
The productivity does decline somewhat in other seasons but remains substantial enough to warrant investment in solar infrastructure. In autumn, the daily energy output per kW installed averages around 3.54 kWh; it further drops to about 3.16 kWh in winter due to shorter daylight hours and possibly overcast skies before rebounding to approximately 4.96 kWh during spring.
The optimal tilt angle for fixed-panel installations at this location is towards the south at an angle of approximately 31 degrees from horizontal level; this orientation maximizes sunlight exposure throughout the year.
While Shangqiu has generally suitable conditions for solar power generation, potential impediments such as heavy rainfall or snowfall may occasionally impact energy production levels by obscuring sunlight or affecting panel efficiency directly through accumulation on their surface; these weather events are not unique to Shangqiu though and can occur across other regions within the Northern Sub Tropics too.
To mitigate these potential issues when installing solar panels, certain preventative measures can be taken into consideration such as incorporating a steeper tilt angle or employing self-cleaning mechanisms on panels which would help maintain optimal performance levels despite adverse environmental factors by allowing rainwater or melting snow to slide off more easily instead of accumulating on their surface.
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 Shangqiu
Seasonal solar PV output for Latitude: 34.4515, Longitude: 115.6479 (Shangqiu, 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 31° South in Shangqiu, China
To maximize your solar PV system's energy output in Shangqiu, China (Lat/Long 34.4515, 115.6479) throughout the year, you should tilt your panels at an angle of 31° 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 Shangqiu, 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 Shangqiu, China. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 31° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 18° South in Summer | 40° South in Autumn | 50° South in Winter | 27° 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 Shangqiu, 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 Shangqiu, 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 Shangqiu, China
The topography around Shangqiu, China is generally flat with some rolling hills. Areas to the west and northwest of the city are most suitable for large-scale solar PV installations due to their open spaces and clear skies. The terrain is mostly free from obstructions such as trees or buildings that could cast shadows on the solar panels. Additionally, these areas have high levels of sunshine year round which makes them ideal for harvesting energy from the sun.
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.
