Gyeongsan-si, located in South Korea, offers a reasonably good location for solar PV energy generation throughout the year. Situated in the Northern Temperate Zone, this area experiences distinct seasons that influence solar energy production.

Seasonal Solar Performance

Solar energy output varies significantly across seasons in Gyeongsan-si. Spring and summer are the most productive periods, with daily outputs of 5.53 kWh and 5.43 kWh per kW of installed solar capacity, respectively. Autumn sees a moderate decrease to 3.79 kWh/day, while winter experiences the lowest output at 3.36 kWh/day.

The substantial difference between peak and low seasons suggests that while solar energy is viable year-round, supplementary energy sources might be beneficial during the less productive months.

Optimal Panel Installation

To maximize year-round solar energy production in Gyeongsan-si, fixed solar panels should be installed at a tilt angle of 33 degrees facing south. This angle has been calculated to optimize energy capture across all seasons, taking into account the location's latitude and the Earth's elliptical orbit.

Environmental and Weather Considerations

While Gyeongsan-si is generally suitable for solar energy production, there are some environmental factors to consider:

1. Monsoon season: South Korea experiences a summer monsoon, which can lead to increased cloud cover and rainfall, potentially reducing solar output.
2. Air pollution: Industrial activities in nearby areas may contribute to air pollution, which can slightly decrease solar panel efficiency.

To mitigate these factors, consider the following preventative measures:

• Install high-quality, weather-resistant panels that perform well in humid conditions.
• Implement a regular cleaning schedule to remove dust and pollutants from panel surfaces.
• Use micro-inverters or power optimizers to minimize the impact of partial shading on overall system performance.

By taking these precautions, solar energy systems in Gyeongsan-si can maintain higher efficiency and productivity throughout the year, despite occasional environmental challenges.

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

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 124 locations across South Korea. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Gyeongsan-si

Seasonal solar PV output for Latitude: 35.824, Longitude: 128.7304 (Gyeongsan-si, 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 33° South in Gyeongsan-si, South Korea

To maximize your solar PV system's energy output in Gyeongsan-si, South Korea (Lat/Long 35.824, 128.7304) throughout the year, you should tilt your panels at an angle of 33° 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 Gyeongsan-si, 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 Gyeongsan-si, South Korea. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° 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.

Calculate solar panel row spacing in Gyeongsan-si, 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 Gyeongsan-si, 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 Gyeongsan-si, South Korea

Gyeongsan-si, located in South Korea, is situated in a region with diverse topography. The city itself is nestled in a relatively flat basin, surrounded by more varied terrain. To the west and northwest of Gyeongsan-si, the landscape gradually rises into rolling hills and low mountains, part of the Taebaek Mountain Range. These elevations provide a natural backdrop to the city and create a picturesque setting. To the east and southeast of Gyeongsan-si, the terrain becomes more level, transitioning into a broader plain that extends towards the coast. This area is characterized by gentler slopes and more open spaces, with scattered agricultural fields and small settlements dotting the landscape.

Suitable Areas for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Gyeongsan-si, the areas to the east and southeast appear most promising. These regions offer several advantages for solar energy development: Firstly, the flatter terrain in these directions provides ample space for the installation of extensive solar panel arrays. The open nature of the landscape means there are fewer natural obstacles that could cast shadows or interfere with solar energy collection. Secondly, the gentler slopes in these areas make construction and maintenance of solar facilities more straightforward and cost-effective. The land is also likely to receive more consistent sunlight throughout the day due to the lack of significant geographical features that might obstruct the sun's rays. Additionally, the proximity to existing infrastructure in and around Gyeongsan-si could facilitate easier grid connection and transportation of materials for solar farm construction. It's worth noting that while the hilly areas to the west and northwest may offer some suitable locations for smaller solar installations, their varied topography and potential for shadowing make them less ideal for large-scale projects. However, these elevated areas could potentially be utilized for wind energy projects, complementing any solar developments in the flatter regions. Before any solar PV project is undertaken, detailed site-specific assessments would be necessary to evaluate factors such as local climate conditions, land availability, and environmental impact. These studies would ensure the most efficient and sustainable use of the area's solar energy potential.
