Solar PV Analysis of Jongno-gu, South Korea
Jongno-gu in South Korea is a decent location for solar energy production year-round, but there are better times than others. During the summer and spring, you can expect to generate more energy (around 5.53kWh/day and 5.35kWh/day respectively) compared to autumn and winter (3.73kWh/day and 2.95kWh/day). This means that the sunniest months will provide more electricity.
To get the most out of your solar panels throughout the year, they should be installed at an angle of 34 degrees facing south. This position will allow them to capture as much sunlight as possible.
Local factors that could potentially hinder solar production include weather conditions like cloud coverage or pollution levels which may block sunlight from reaching the panels. Jongno-gu's urban setting could also present challenges with shading from tall buildings or other structures.
To mitigate these issues, it's important to consider panel placement carefully during installation - try to avoid areas with potential shading issues where possible. Regular cleaning of panels can also help ensure optimal performance by removing dust or debris that might accumulate over time.
In conclusion, while Jongno-gu isn't perfect for solar power generation due its seasonal variations in sunlight exposure and potential local obstacles such as tall buildings or pollution, with careful planning during installation it could still be a viable option for renewable 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 Jongno-gu
Seasonal solar PV output for Latitude: 37.613, Longitude: 126.9623 (Jongno-gu, 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 Jongno-gu, South Korea
To maximize your solar PV system's energy output in Jongno-gu, South Korea (Lat/Long 37.613, 126.9623) 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 Jongno-gu, 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 Jongno-gu, 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 Jongno-gu, 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 Jongno-gu, 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 Jongno-gu, South Korea
Jongno-gu, located in the heart of Seoul, South Korea, is predominantly urban with a mix of modern skyscrapers and traditional Korean architecture. It's surrounded by several mountains including Inwangsan to the west and Bugaksan, Naksan, and Namsan to the north and south. The Han River flows through southern Seoul adding to its diverse topography.
For large scale solar PV installations, open areas with maximum sun exposure are ideal. However, given Jongno-gu's dense urban environment and mountainous surroundings, such spaces might be limited within the district itself.
Nearby areas that could potentially accommodate large-scale solar PV include:
1. Flat rooftops of buildings: Given the urban setting of Jongno-gu with numerous high-rise buildings having flat rooftops can be ideal for installing solar panels.
2. Unused lands or brownfield sites in outskirts: If there are any unused lands or brownfield sites on the outskirts of Seoul city where there is less shadow effect from buildings or mountains could be suitable for this purpose.
3. Water bodies: Floating solar farms on nearby water bodies like sections of Han River can also be considered as they have proved successful in other parts of South Korea.
4. Mountain slopes: Although not as efficient as flat land due to potential shading issues and installation challenges; if properly designed considering slope angle & orientation towards sun rays along with local climatic conditions (like snowfall), mountain slopes could also serve as potential locations for solar panel installation.
It should also be noted that these suggestions would need feasibility studies taking into account factors such as local regulations regarding renewable energy installations, environmental impact assessments etc., before implementation.
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.
