The solar energy output in Seogwipo fluctuates across the seasons. Spring and summer prove to be the most productive periods, with daily outputs of 5.56 kWh and 5.47 kWh per kW of installed solar capacity, respectively. Autumn sees a moderate decline to 3.89 kWh/day, while winter experiences the lowest output at 2.81 kWh/day.

For those considering fixed panel installations in Seogwipo, the ideal tilt angle to maximize year-round solar production is 29 degrees facing south. This optimal angle has been calculated taking into account daily solar elevation angles, panel tilt optimization, and NASA's solar irradiance data.

Environmental and Weather Factors

While Seogwipo's location is generally favorable for solar energy production, there are some environmental factors to consider. The region experiences a subtropical climate with occasional typhoons and heavy rainfall, particularly during the summer monsoon season. These weather patterns can temporarily reduce solar output and potentially damage poorly secured installations.

To mitigate these risks, it's crucial to implement robust mounting systems that can withstand high winds and heavy rain. Additionally, using high-quality, water-resistant solar panels and ensuring proper drainage around the installation site can help maintain optimal performance during adverse weather conditions.

Another factor to consider is the potential for salt spray due to Seogwipo's coastal location. This can lead to corrosion of solar equipment over time. Choosing corrosion-resistant materials and applying protective coatings can help extend the lifespan of the solar installation in this environment.

Maximizing Solar Production

To make the most of Seogwipo's solar potential, consider the following strategies:

• Implement a solar tracking system to follow the sun's path, potentially increasing energy yield by up to 30%.
• Regular cleaning and maintenance to remove salt deposits and other debris that may accumulate on panels.

By addressing these factors and optimizing panel placement, Seogwipo can be an excellent location for solar energy production, particularly during the spring and summer months when output is at its peak.

Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Ideally tilt fixed solar panels 29° South in Seogwipo, South Korea

To maximize your solar PV system's energy output in Seogwipo, South Korea (Lat/Long 33.2934, 126.2744) throughout the year, you should tilt your panels at an angle of 29° 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 Seogwipo, 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 Seogwipo, South Korea. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 29° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
17° South in Summer	39° South in Autumn	48° South in Winter	26° 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 Seogwipo, 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 Seogwipo, 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 Seogwipo, South Korea

Seogwipo, located on the southern coast of Jeju Island in South Korea, is characterized by a diverse and picturesque topography. The area surrounding Seogwipo features a unique blend of volcanic landscapes, coastal plains, and rolling hills, creating a stunning natural environment. The most prominent feature of Seogwipo's topography is the presence of Hallasan, a dormant volcano that dominates the center of Jeju Island. Rising to an elevation of 1,950 meters (6,398 feet), Hallasan's gentle slopes extend outward, gradually descending towards the coast where Seogwipo is situated. These slopes are covered with lush forests, creating a green belt that surrounds the city. As one moves closer to the coast, the terrain becomes more varied. The landscape is dotted with numerous smaller volcanic cones, known as oreum, which are a distinctive feature of Jeju Island. These parasitic cones range in height from a few dozen to several hundred meters and contribute to the area's undulating topography. The coastline around Seogwipo is predominantly rocky, with dramatic cliffs and sea stacks formed by volcanic activity and erosion. Interspersed among these rugged formations are small, picturesque beaches and coves. The coast is also home to unique geological features such as columnar jointed lava formations, adding to the area's natural beauty.

Suitability for Large-Scale Solar PV

When considering areas near Seogwipo for large-scale solar PV installations, several factors come into play. The most suitable locations would likely be found in the gently sloping areas south of Hallasan, moving towards the coast. These areas offer a good balance of open space, favorable elevation, and proximity to existing infrastructure. The volcanic plains and lower slopes of Hallasan provide expansive, relatively flat areas that could accommodate large solar arrays. These locations benefit from good sun exposure throughout the day, with minimal shading from surrounding terrain. Additionally, their elevation helps to mitigate some of the coastal effects like sea mist that could reduce solar efficiency. Areas to the east and west of Seogwipo, where the terrain is less rugged, could also be suitable for solar PV installations. These regions often feature agricultural land or less densely forested areas, which could potentially be repurposed for solar energy production. It's important to note that while the coastal areas offer ample sunlight, they may be less ideal due to limited available land and potential environmental concerns. The immediate vicinity of Seogwipo city itself would likely be too densely populated for large-scale installations. Any solar PV project in this region would need to carefully consider the unique ecological sensitivity of Jeju Island, balancing energy production with preservation of the island's natural beauty and biodiversity. Proper environmental impact assessments and community engagement would be crucial in determining the most appropriate locations for such developments.
