Solar PV Analysis of Kaifeng, China
In Kaifeng, Henan, China (latitude: 34.8062, longitude: 114.2763), the potential for solar power generation is promising due to its seasonal average daily solar irradiance per kW of installed solar panels: 5.19 kWh in summer, 3.53 kWh in autumn, 3.21 kWh in winter, and 5.05 kWh in spring. This indicates that the city experiences higher energy production during summer months as a result of longer daylight hours.
For optimal energy production with a fixed panel installation at this location, it is recommended to tilt the panels at an angle of 31 degrees facing south.
However, it is important to consider local factors that may impact solar production efficiency in Kaifeng such as heavy rainfall or foggy weather conditions which can reduce sunlight availability and consequently decrease energy output from photovoltaic (PV) panels. To mitigate these potential challenges and ensure greater energy production throughout the year, it may be beneficial to implement preventative measures such as regular maintenance and cleaning of PV panels to remove any debris or dirt buildup that could obstruct sunlight absorption on their surface or considering alternative mounting options like elevated structures for better exposure during foggy days if necessary.
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 73 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 Kaifeng
Seasonal solar PV output for Latitude: 34.8062, Longitude: 114.2763 (Kaifeng, 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 Kaifeng, China
To maximize your solar PV system's energy output in Kaifeng, China (Lat/Long 34.8062, 114.2763) 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 Kaifeng, 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 Kaifeng, 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.
Topography for solar PV around Kaifeng, China
The topography around Kaifeng, China is mostly flat and low-lying. The area is part of the North China Plain which is largely composed of alluvial plains that are ideal for large scale solar PV installations. The nearby areas most suited to large scale solar PV would be the open fields and flat terrain surrounding the city, as well as areas with a high concentration of rooftops that could be used for distributed solar projects.
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.
