Boryeong, South Korea presents a moderately favorable location for year-round solar PV energy generation, though with significant seasonal variations typical of its Northern Temperate Zone climate.

Seasonal Solar Performance

The solar energy output at this location shows strong seasonal patterns. Summer delivers the highest production at 5.57 kWh per day per kW of installed capacity, making it the peak season for solar generation. Spring follows closely with 5.35 kWh per day per kW, representing nearly equivalent performance to summer months. Autumn sees a notable decline to 3.76 kWh per day per kW, while winter presents the most challenging conditions with only 2.84 kWh per day per kW of production. This represents a roughly 50% reduction from peak summer output. For optimal year-round performance at this location, solar panels should be installed at a fixed tilt angle of 32 degrees facing south. This angle maximizes total annual energy production by accounting for the sun's varying elevation throughout the year and weighting for seasonal solar potential.

Environmental and Weather Challenges

Several local factors can significantly impact solar production in Boryeong and require careful consideration during installation:

• Monsoon Season: South Korea experiences heavy rainfall and prolonged cloudy periods during summer monsoons, which can substantially reduce solar output despite this being the peak production season
• Yellow Dust (Hwangsa): Spring dust storms originating from China deposit fine particles on solar panels, creating a film that blocks sunlight and reduces efficiency
• High Humidity: Coastal proximity creates persistent humidity that can cause moisture-related equipment issues and promote dust adhesion to panel surfaces
• Snow Accumulation: Winter snowfall can completely block solar panels, eliminating energy production until snow melts or is removed

Preventative Installation Measures

To maximize solar energy production despite these challenges, several installation strategies prove essential. Panel mounting systems should incorporate adequate drainage and ventilation to prevent moisture buildup and ensure quick drying after rain events. Installing panels at the recommended 32-degree tilt angle serves dual purposes - optimizing solar collection while promoting natural snow shedding and rain runoff. Steeper angles help prevent snow accumulation that could otherwise block panels for extended periods. Regular cleaning schedules become crucial, particularly after dust storm events and during high-pollen seasons. Automated cleaning systems or easily accessible manual cleaning arrangements should be incorporated into the installation design. Robust electrical components rated for high humidity environments prevent corrosion and electrical failures. Proper grounding and moisture sealing of all connections ensures reliable operation in coastal conditions.

Overall Assessment

Despite seasonal variations and environmental challenges, Boryeong offers reasonable solar potential with strong spring and summer performance. The key to success lies in proper installation techniques that address local weather patterns and implementing maintenance practices that keep systems operating efficiently year-round.

Solar output per kW of installed solar PV by season in Boryeong

Seasonal solar PV output for Latitude: 36.352, Longitude: 126.6023 (Boryeong, 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 32° South in Boryeong, South Korea

To maximize your solar PV system's energy output in Boryeong, South Korea (Lat/Long 36.352, 126.6023) throughout the year, you should tilt your panels at an angle of 32° 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 Boryeong, 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 Boryeong, South Korea. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
20° South in Summer	41° South in Autumn	51° South in Winter	29° 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.

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 Boryeong, South Korea

Topographical Features of Boryeong Region

The topography around Boryeong, South Korea presents a diverse landscape characterized by gentle rolling hills, coastal plains, and proximity to the Yellow Sea. This western coastal city sits within a region that features relatively low elevation changes compared to the mountainous terrain found in other parts of South Korea. The area is dominated by sedimentary formations that have created a landscape of moderate undulations rather than steep gradients. The immediate vicinity of Boryeong consists primarily of coastal lowlands that extend inland for several kilometers before gradually rising into low hills. These hills rarely exceed 200 meters in elevation, creating a landscape that is neither completely flat nor dramatically mountainous. The terrain includes numerous valleys and gentle slopes that have been shaped by both geological processes and centuries of agricultural development. Moving inland from the coast, the topography transitions into a series of low ridges and broad valleys that run in a generally north-south orientation. This pattern is typical of the western Korean peninsula, where the landscape has been influenced by both tectonic activity and erosional processes. The soil composition in much of the region consists of alluvial deposits mixed with weathered sedimentary rock, creating relatively stable ground conditions.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations around Boryeong would be the extensive coastal plains that stretch both north and south of the city. These areas offer several advantages including minimal slope variations, which reduce installation complexity and costs while maximizing panel efficiency through optimal positioning. The relatively flat terrain in these coastal zones eliminates the need for extensive grading or terracing that would be required in more mountainous regions. The broad valleys located approximately 10 to 20 kilometers inland from Boryeong represent another excellent opportunity for solar development. These valleys typically feature gentle slopes facing south or southwest, which is ideal for solar panel orientation in the northern hemisphere. The valley floors are often expansive enough to accommodate large solar arrays while the surrounding low hills provide some natural wind protection without creating significant shading issues. Agricultural areas on the coastal plains could potentially be suitable for solar development, particularly those with well-drained soils and minimal slope. These locations benefit from existing road infrastructure and electrical grid connections, which can significantly reduce development costs. The stable geological conditions in these areas also minimize foundation requirements and long-term maintenance concerns. Areas to avoid for solar development would include the steeper hillsides and ridgetops, not only due to installation challenges but also because these locations may be more environmentally sensitive or designated for conservation purposes. Additionally, the immediate coastal zone, while topographically suitable, may present challenges related to salt air corrosion and extreme weather exposure that could affect long-term system performance and maintenance requirements.
