Bundang-gu, South Korea, situated at latitude 37.377 and longitude 127.1091, offers a moderate potential for solar energy generation throughout the year. Located in the Northern Temperate Zone, this area experiences distinct seasonal variations that impact solar PV performance.

Seasonal Solar Output

The solar energy production in Bundang-gu fluctuates significantly across seasons. Summer stands out as the most productive period, with an average daily output of 5.34 kWh per kW of installed solar capacity. Spring follows closely behind, generating 5.13 kWh/day. Autumn sees a noticeable decrease to 3.57 kWh/day, while winter experiences the lowest output at 2.92 kWh/day.

These figures indicate that the location is most ideal for solar energy generation during the warmer months, particularly from late spring through early autumn. During this period, longer daylight hours and generally clearer skies contribute to enhanced solar panel efficiency.

Optimal Panel Installation

To maximize year-round solar energy production in Bundang-gu, fixed solar panels should be installed at a tilt angle of 34 degrees facing south. This angle is calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the Earth's elliptical orbit and the location's specific latitude.

Environmental Factors and Mitigation Strategies

Several environmental factors in Bundang-gu can potentially impact solar energy production:

1. Seasonal monsoons: Heavy rainfall during the summer monsoon season can reduce solar output. Installing water-resistant panels and ensuring proper drainage systems can mitigate this issue.
2. Air pollution: Bundang-gu, being part of the greater Seoul metropolitan area, may experience periods of high air pollution, which can decrease solar panel efficiency. Regular cleaning and maintenance of panels can help counteract this effect.
3. Snow accumulation: Winter snowfall can temporarily cover panels, reducing energy production. Installing panels at a steeper angle or using snow-shedding systems can help prevent snow buildup.

By addressing these factors through thoughtful installation practices and regular maintenance, solar energy systems in Bundang-gu can achieve more consistent and efficient performance throughout the year.

Solar output per kW of installed solar PV by season in Bundang-gu

Seasonal solar PV output for Latitude: 37.377, Longitude: 127.1091 (Bundang-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 Bundang-gu, South Korea

To maximize your solar PV system's energy output in Bundang-gu, South Korea (Lat/Long 37.377, 127.1091) 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 Bundang-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 Bundang-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	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 Bundang-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 Bundang-gu, South Korea.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Bundang-gu, South Korea

Bundang-gu, located in the city of Seongnam in South Korea's Gyeonggi Province, is situated in a diverse topographical area that combines urban development with natural landscapes. The region is characterized by a mix of gently rolling hills, flat areas, and some more pronounced elevations. To the west and northwest of Bundang-gu, the terrain is relatively flat, consisting of urban areas and developed land. This area is part of the larger Seoul Capital Area, which extends into a broad valley system. As you move eastward, the landscape becomes more varied, with low hills and small valleys interspersed throughout the region.

Surrounding Mountains

The most prominent topographical features in the vicinity of Bundang-gu are the mountains that surround the area. To the east lies Cheonggyesan Mountain, which forms a natural boundary between Bundang-gu and neighboring districts. This mountain, with its forested slopes, provides a stark contrast to the urban development below. Further to the southeast, the terrain becomes more mountainous, with several peaks forming part of the larger Gwangju Mountain Range. These mountains create a picturesque backdrop for the city and contribute to the area's overall topographical diversity.

Tancheon Stream

A notable feature of Bundang-gu's topography is the Tancheon Stream, which flows through the district from south to north. This waterway has played a significant role in shaping the local landscape, creating a natural corridor through the urban area and influencing the development patterns of the surrounding neighborhoods.

Potential for Solar PV Installation

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors need to be taken into account. The ideal locations would combine favorable topography with minimal environmental impact and proximity to existing infrastructure. The flatter areas to the west and northwest of Bundang-gu could potentially be suitable for solar PV installations. These regions offer relatively level ground, which is advantageous for the construction and maintenance of large-scale solar farms. Additionally, being closer to urban centers, these areas may have better access to existing power grids and transportation networks. However, it's important to note that much of this flat land is already developed or designated for urban use. Therefore, any large-scale solar projects in these areas would likely need to be integrated into existing structures or planned as part of new developments. Another potential area for solar PV installations could be the gentler slopes of the surrounding hills, particularly those facing south or southwest. These locations could provide optimal sun exposure throughout the day. However, care would need to be taken to balance energy production with preservation of natural habitats and scenic views. In conclusion, while Bundang-gu itself may have limited space for large-scale solar PV due to its urban nature, the surrounding regions offer potential opportunities. The most promising areas would likely be found in the less developed, flatter regions to the west and northwest, or on suitable hillsides that offer good sun exposure without significant environmental impact.
