Solar PV Analysis of Anyang-si, South Korea
The location at Anyang-si, South Korea is moderately suitable for generating energy via solar photovoltaic (PV) systems year-round. The amount of electricity that can be produced by a solar PV system installed in this location varies by season. In the summer and spring, the system can generate around 5.53 and 5.35 kilowatt-hours per day respectively for each kilowatt of solar installed, which are relatively high rates of production. However, in autumn and winter, these figures drop to 3.73 and 2.95 kilowatt-hours per day respectively.
This means that the most ideal times to generate solar power at this location would be during the spring and summer months when sunlight is more abundant due to longer daylight hours and higher sun angles.
For a fixed panel installation at this location, tilting panels towards the south at an angle of approximately 33 degrees will maximize total year-round production from solar PV systems because it aligns them more directly with the path of the sun across the sky throughout different seasons.
However, there may be some environmental or weather factors that could hinder solar production in Anyang-si such as heavy snowfall or atmospheric pollution which may block sunlight reaching panels especially during winter months when snowfall is common in South Korea.
To counteract these potential impediments to energy generation:
1) Regular cleaning & maintenance: Ensure regular cleaning of panels especially after snowfalls or dust storms to remove any debris that might obstruct sunlight.
2) Proper installation: Consider installing your panels at an optimal tilt angle (33 degrees South) so they receive maximum sunlight exposure all year round.
3) Snow guards: If heavy snowfall is common in your area consider installing snow guards on your roof near your panels to prevent buildup on them.
4) Air quality monitoring: Monitor local air quality reports; if you live in an area with high levels of air pollution you might want to consider investing in solar panel coatings that can help reduce the impact of air pollution on your panels.
Overall, while there are some challenges with generating solar power in Anyang-si, South Korea due to seasonal variations and potential weather conditions, with proper installation and maintenance strategies these issues can be mitigated to maximize energy production.
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 124 locations across South Korea. 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 Anyang-si
Seasonal solar PV output for Latitude: 37.3907, Longitude: 126.9167 (Anyang-si, South Korea), 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 33° South in Anyang-si, South Korea
To maximize your solar PV system's energy output in Anyang-si, South Korea (Lat/Long 37.3907, 126.9167) throughout the year, you should tilt your panels at an angle of 33° 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 Anyang-si, South Korea
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 Anyang-si, South Korea. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 21° South in Summer | 42° South in Autumn | 52° South in Winter | 30° 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 Anyang-si, South Korea
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 Anyang-si, South Korea.
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 Anyang-si, South Korea
Anyang-si is located in the western part of South Korea, within the province of Gyeonggi. The region's topography consists mainly of flat plains and small hills, with a few mountainous areas to the east and south.
For large-scale solar PV installations, flat or gently sloping areas are typically most suitable as they require less earthwork and can accommodate more panels per unit area. Given this, the plains around Anyang-si would likely be well-suited for such a project.
However, it's important to note that other factors also play a critical role in determining suitability for solar PV installations. These include solar irradiance (the amount of sunlight that reaches the ground), land use restrictions, proximity to electricity transmission lines, and environmental considerations.
As such, while the topography around Anyang-si seems promising for large-scale solar PV projects based on its relatively flat terrain alone; further detailed studies including those aspects mentioned above would be necessary before making any definitive conclusions about its suitability.
South Korea solar PV Stats as a country
South Korea ranks 8th in the world for cumulative solar PV capacity, with 18,161 total MW's of solar PV installed. This means that 3.80% of South Korea's total energy as a country comes from solar PV (that's 21st in the world). Each year South Korea is generating 350 Watts from solar PV per capita (South Korea ranks 9th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in South Korea?
Yes, there are incentives for businesses wanting to install solar energy in South Korea. The Korean government offers a variety of financial incentives and subsidies for businesses that install solar energy systems. These include tax credits, grants, loans, and other forms of support. Additionally, the government has implemented a feed-in tariff system which guarantees a fixed price for electricity generated from renewable sources such as solar power. This helps to make the installation of solar energy systems more attractive to businesses by providing them with a guaranteed return on their investment.
