Yangsan, South Korea, located at latitude 35.3447 and longitude 129.0299, offers a generally favorable environment for solar PV energy generation throughout the year. Situated in the Northern Temperate Zone, this location experiences distinct seasonal variations in solar output.

Seasonal Solar Performance

The solar energy production in Yangsan demonstrates significant fluctuations across seasons. Spring and summer emerge as the most productive periods, with daily outputs of 5.33 kWh and 5.29 kWh per kW of installed solar capacity, respectively. Autumn sees a moderate decrease to 3.67 kWh/day, while winter experiences the lowest output at 3.25 kWh/day.

These figures indicate that Yangsan is particularly well-suited for solar energy generation during the warmer months, with spring slightly outperforming summer. The substantial drop in winter output, while notable, still provides a reasonable baseline for year-round energy production.

Optimal Panel Installation

To maximize year-round solar energy production in Yangsan, fixed solar panels should be installed at a tilt angle of 32 degrees facing south. This angle has been calculated to optimize the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.

Environmental Considerations

While Yangsan's climate is generally conducive to solar energy production, there are some environmental factors to consider:

1. Monsoon season: Yangsan experiences a summer monsoon, which can lead to increased cloud cover and rainfall, potentially reducing solar output during this period.
2. Air pollution: Like many urban areas in South Korea, Yangsan may experience occasional air pollution, which can slightly reduce solar panel efficiency.

Preventative Measures

To mitigate these environmental challenges and ensure optimal solar energy production, consider the following measures:

1. Install high-quality, weather-resistant panels capable of performing well in humid conditions.
2. Implement a regular cleaning schedule to remove dust and pollutants from panel surfaces.
3. Consider using microinverters or power optimizers to minimize the impact of partial shading on overall system performance.
4. Ensure proper drainage systems are in place to handle heavy rainfall during the monsoon season.

In conclusion, despite some seasonal variations and environmental considerations, Yangsan's location provides a solid foundation for solar PV energy generation throughout the year, with spring and summer offering particularly high yields.

Ideally tilt fixed solar panels 32° South in Yangsan, South Korea

To maximize your solar PV system's energy output in Yangsan, South Korea (Lat/Long 35.3447, 129.0299) 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 Yangsan, 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 Yangsan, 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
19° South in Summer	41° South in Autumn	51° South in Winter	28° 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 Yangsan, 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 Yangsan, 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 Yangsan, South Korea

Yangsan, a city in South Gyeongsang Province, South Korea, is situated in a region characterized by diverse topography. The landscape surrounding Yangsan is a blend of mountainous terrain, rolling hills, and flat lowlands, creating a picturesque and varied environment. To the west and northwest of Yangsan, the terrain is dominated by the Yeongnam Alps, a mountain range that runs through the southeastern part of the Korean Peninsula. These mountains, while not as tall as their European namesake, still provide significant elevation changes and rugged terrain. The peaks and ridges of the Yeongnam Alps create a natural backdrop for the city and influence local weather patterns.

Lowlands and Valleys

In contrast to the mountainous regions, the eastern and southern parts of Yangsan feature more gentle topography. Here, the land gradually slopes down towards the coastal areas of the nearby cities of Busan and Ulsan. This transition zone is characterized by lower hills, wider valleys, and more expansive flat areas. The Yangsan Fault, a major geological feature, runs through the region and has played a significant role in shaping the local topography. This fault line has created a series of valleys and basins, some of which have been utilized for urban development and agriculture.

Rivers and Waterways

Several rivers and streams flow through the Yangsan area, further sculpting the landscape. The most notable is the Yangsan River, which meanders through the city and surrounding countryside. These waterways have carved out valleys and floodplains, contributing to the area's agricultural potential.

Potential for Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations would combine relatively flat terrain, good sun exposure, and proximity to existing infrastructure. The lowland areas to the east and southeast of Yangsan present promising opportunities for solar PV development. These regions offer more expansive flat or gently sloping terrain, which is easier and more cost-effective to develop for large-scale solar installations. The reduced shadowing effect from mountains in these areas also ensures better sun exposure throughout the day. Additionally, the valleys between the hills and mountains could provide suitable locations, particularly those oriented in an east-west direction to maximize sunlight exposure. However, care would need to be taken to avoid areas prone to flooding or with rich agricultural value. It's worth noting that while the mountainous regions to the west might seem appealing due to their elevation, the rugged terrain and potential shadowing effects make them less ideal for large-scale solar projects. However, smaller installations on south-facing slopes could still be viable. Ultimately, the most suitable areas for solar PV near Yangsan would likely be found in the transitional zones between the mountains and the coastal plains, where the balance of flat land, good sun exposure, and accessibility to infrastructure is optimal.
