Solar PV Analysis of Seoul, South Korea
The location in Seoul, South Korea at latitude 37.6019 and longitude 127.0034 is suitable for generating solar power throughout the year due to its seasonal energy production potential. The average daily energy output per kW of installed solar capacity varies by season: 5.36 kWh in summer, 3.63 kWh in autumn, 2.98 kWh in winter, and 5.17 kWh in spring.
Summer has the highest energy generation potential because it offers more daylight hours for solar power production compared to other seasons with fewer daylight hours available for harnessing sunlight through photovoltaic (PV) panels.
However, certain weather conditions and environmental factors in Seoul could pose challenges to solar power generation efficiency. High levels of air pollution or heavy cloud cover can reduce the amount of sunlight reaching the panels, thereby decreasing their electricity production capabilities; on the other hand, clear skies with low air pollution will result in higher yields from the same system size.
During winter months, snowfall may obstruct direct sunlight from reaching the panels and reduce their efficiency while strong winds can cause physical damage if they are not properly secured against gusts or storms passing through the area.
To optimize solar energy production at this location, it is recommended that fixed panel installations be tilted at an angle of 34 degrees facing southward. This orientation maximizes exposure to sunlight throughout the year without requiring a tracking system.
In conclusion, while there are some environmental and weather-related challenges that may affect solar power generation efficiency at this location in Seoul, proper installation techniques such as securing panels against wind damage and tilting them at an optimal angle can help ensure greater energy production year-round.
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 Seoul
Seasonal solar PV output for Latitude: 37.6019, Longitude: 127.0034 (Seoul, 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 34° South in Seoul, South Korea
To maximize your solar PV system's energy output in Seoul, South Korea (Lat/Long 37.6019, 127.0034) throughout the year, you should tilt your panels at an angle of 34° 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 Seoul, 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 Seoul, South Korea. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° 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 | 31° 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 Seoul, 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 Seoul, 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 Seoul, South Korea
The topography around Seoul, South Korea is generally flat and low lying. Areas to the north and east of the city are relatively hilly, while areas to the south and west are more open with fewer hills. The most suitable areas for large-scale solar PV installations would be in the southern and western parts of Seoul, as these regions receive more direct sunlight than other parts of the city due to their lower elevation. Additionally, these areas tend to have less cloud cover than other parts of Seoul which makes them ideal for solar energy production.
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.
