Gangdong-gu, located in Seoul, South Korea, presents a moderately favorable environment for solar PV energy generation throughout the year. This location in the Northern Temperate Zone experiences distinct seasonal variations in solar energy production.

Seasonal Solar Performance

Summer stands out as the peak season for solar energy generation, with an impressive output of 5.36 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, producing 5.17 kWh/day/kW. These seasons offer the most sunlight hours and intensity, making them ideal for maximizing solar energy production.

Autumn sees a noticeable decrease in solar output, generating 3.63 kWh/day/kW. Winter experiences the lowest production at 2.98 kWh/day/kW, primarily due to shorter daylight hours and the sun's lower position in the sky.

Optimal Panel Installation

To maximize year-round solar energy production in Gangdong-gu, fixed solar panels should be tilted at a 34-degree angle facing south. This optimal angle ensures the panels capture the most sunlight throughout the year, accounting for seasonal variations in the sun's position.

Environmental and Weather Considerations

While Gangdong-gu's climate is generally conducive to solar energy production, there are some factors that could potentially impact efficiency:

• Air pollution: Seoul's urban environment can sometimes experience high levels of air pollution, which may reduce sunlight reaching the panels.
• Monsoon season: Heavy rainfall during the summer monsoon could temporarily decrease solar output.

To mitigate these factors, consider installing high-quality, weather-resistant panels with anti-soiling coatings. Regular cleaning and maintenance can help combat the effects of air pollution. Additionally, a slight increase in the panel tilt angle can promote natural cleaning during rainy periods.

Despite these challenges, Gangdong-gu remains a viable location for solar PV installations, with ample opportunity to harness renewable energy throughout the year, particularly during the spring and summer months.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

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

Seasonal solar PV output for Latitude: 37.536, Longitude: 127.1426 (Gangdong-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 Gangdong-gu, South Korea

To maximize your solar PV system's energy output in Gangdong-gu, South Korea (Lat/Long 37.536, 127.1426) 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 Gangdong-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 Gangdong-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 Gangdong-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 Gangdong-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 Gangdong-gu, South Korea

Gangdong-gu, located in the eastern part of Seoul, South Korea, is situated in an area with varied topography. The district is characterized by a mix of urban development and natural features, creating a diverse landscape. To the north and east of Gangdong-gu, the terrain becomes more elevated, with gentle hills and small mountains forming part of the landscape. The most prominent of these is Achasan Mountain, which rises to an elevation of about 287 meters above sea level. This area provides a stark contrast to the more densely populated urban center of Gangdong-gu. The southern and western parts of Gangdong-gu are generally flatter, with the Han River flowing along the district's southern border. This area is more heavily urbanized, with residential and commercial developments dominating the landscape. The river's presence has shaped the local topography, creating a wide, flat floodplain that has been extensively developed over time.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal location would have ample open space, minimal shading, and relatively flat terrain to simplify installation and maximize sun exposure. The areas to the east and northeast of Gangdong-gu, extending into Gyeonggi Province, might offer more suitable locations for large-scale solar PV projects. These regions tend to have more open space and less dense urban development. The gently rolling hills in this area could potentially be utilized for solar installations, provided they are oriented correctly to maximize sunlight exposure. However, it's important to note that much of the land surrounding Seoul is either urbanized or protected as green spaces, which may limit the availability of suitable sites for large-scale solar projects. Any potential development would need to carefully consider environmental impacts and local regulations. The flatter areas along the Han River, while potentially suitable from a topographical perspective, are likely to be heavily developed or designated for other uses, making them less ideal for large-scale solar installations. In conclusion, while the immediate vicinity of Gangdong-gu may not offer ideal conditions for large-scale solar PV due to urban density and topographical constraints, areas further east and northeast, where the landscape opens up, could potentially accommodate such projects, subject to careful planning and environmental considerations.
