Solar PV Analysis of Anshan, China
Located at 41.1602 latitude and 123.0301 longitude, Anshan in China is a promising site for solar power generation due to its substantial average daily yield of kilowatt-hours per kilowatt (kWh/kW) of installed solar capacity across all seasons: an impressive 5.41 kWh/kW in summer, a substantial 3.31 kWh/kW during autumn, a respectable 2.68 kWh/kW throughout winter and an outstanding 5.43 kWh/kW over the spring season.
Anshan's position within the Northern Temperate Zone is advantageous for harnessing solar energy as it receives relatively higher sunlight exposure during these periods compared to other parts of the year.
However, potential challenges for solar production in this region could include heavy rainfall or snowfall that may limit sunlight exposure and thus decrease energy output from photovoltaic systems. It is therefore crucial when installing panels in such locations to consider preventative measures such as efficient drainage systems or protective coatings that can help maintain optimal performance despite adverse weather conditions.
In order to maximize year-round efficiency and capture the maximum amount of sunlight possible at this location, it is advisable that panels are set with a tilt angle facing towards south at approximately 37 degrees from horizontal level during installation on fixed mounts.
This strategic placement optimizes the incidence angle between incoming sunlight rays and panel surface throughout different times of year, thereby ensuring maximum absorption of light energy by the photovoltaic cells across all seasons.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° 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 Anshan
Seasonal solar PV output for Latitude: 41.1602, Longitude: 123.0301 (Anshan, 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 37° South in Anshan, China
To maximize your solar PV system's energy output in Anshan, China (Lat/Long 41.1602, 123.0301) throughout the year, you should tilt your panels at an angle of 37° 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 Anshan, 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 Anshan, China. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 25° South in Summer | 46° South in Autumn | 56° South in Winter | 34° 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 Anshan, 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 Anshan, 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 Anshan, China
The topography around Anshan, China is generally flat with low hills. Areas that are most suited to large-scale solar PV installations in the area would be those that have open and unobstructed access to direct sunlight, such as on rooftops or open fields. Additionally, any areas with a southward facing slope can also provide excellent conditions for solar PV systems.
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.
