Solar PV Analysis of Pocheon-si, South Korea
Pocheon-si, South Korea, situated at latitude 37.8927 and longitude 127.2009, presents a varied landscape for solar energy production throughout the year. This location in the Northern Temperate Zone experiences distinct seasonal changes that significantly impact solar PV efficiency.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive 5.36 kWh per day output for each kilowatt of installed solar capacity. Spring follows closely behind, generating 5.17 kWh/day. These seasons offer optimal conditions for solar energy harvesting, with longer daylight hours and generally clearer skies.
Autumn sees a noticeable decrease in production, yielding 3.63 kWh/day. Winter presents the greatest challenge, with output dropping to 2.98 kWh/day per kW installed. This significant seasonal variation underscores the importance of efficient system design to maximize year-round energy capture.
Optimal Panel Positioning
For fixed panel installations in Pocheon-si, the ideal tilt angle is 34 degrees facing South. This angle is calculated to optimize total annual energy production, taking into account the Earth's elliptical orbit and the location's specific solar elevation angles throughout the year.
Environmental Considerations
While Pocheon-si's climate is generally favorable for solar energy, there are some environmental factors to consider:
- Seasonal monsoons: Heavy rainfall during the summer monsoon season can temporarily reduce solar efficiency.
- Air pollution: Pocheon-si's proximity to industrial areas may lead to increased particulate matter in the air, potentially affecting solar panel performance.
Mitigation Strategies
To address these challenges and enhance solar energy production, several preventative measures can be implemented:
Install self-cleaning panels or implement regular cleaning schedules to combat dust and pollution buildup. Consider using anti-reflective coatings on panels to improve light absorption, especially during overcast conditions. Employ robust mounting systems capable of withstanding strong winds during monsoon seasons.
By addressing these factors and optimizing panel placement, Pocheon-si can effectively harness solar energy, contributing to a more sustainable energy future despite seasonal variations in output.
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 Pocheon-si
Seasonal solar PV output for Latitude: 37.8927, Longitude: 127.2009 (Pocheon-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 34° South in Pocheon-si, South Korea
To maximize your solar PV system's energy output in Pocheon-si, South Korea (Lat/Long 37.8927, 127.2009) 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 Pocheon-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 Pocheon-si, 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 | 43° South in Autumn | 53° 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 Pocheon-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 Pocheon-si, South Korea.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Pocheon-si, South Korea
Pocheon-si, located in Gyeonggi Province, South Korea, is characterized by a diverse and hilly topography. The area surrounding the city features a mix of low mountains, rolling hills, and valleys. The landscape is part of the larger Gwangju Mountain Range, which extends through much of the region.
The terrain around Pocheon-si is generally undulating, with elevations ranging from about 50 to 800 meters above sea level. The city itself is nestled in a basin surrounded by higher ground. To the east and northeast, the land rises more steeply, forming part of the mountainous border region between South Korea and North Korea. To the west and southwest, the terrain becomes gradually less rugged, transitioning into more gently rolling hills and eventually flatter areas as you move towards the metropolitan region of Seoul.
Several rivers and streams cut through the landscape, including the Yeongpyeong River, which flows through Pocheon-si. These waterways have carved out valleys and created some flatter areas along their banks. The region also features numerous small lakes and reservoirs, both natural and man-made.
When considering areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, there are a few factors to consider:
- The gently sloping hills to the west and southwest of Pocheon-si could be suitable locations. These areas receive good sun exposure and have less extreme topography, making construction and maintenance easier.
- Some of the broader valley floors, particularly those with a south-facing aspect, could be potential sites for solar farms. These areas are relatively flat and often have good access to existing infrastructure.
- Abandoned or less productive agricultural land in the surrounding region might be repurposed for solar PV installations, provided they have suitable sun exposure and are not too steeply sloped.
It's important to note that while the topography around Pocheon-si offers some potentially suitable areas for solar PV, other factors such as land availability, proximity to power grids, and local regulations would also need to be considered when planning large-scale solar installations. Additionally, South Korea's climate, with its monsoon season and occasional heavy cloud cover, may impact the overall efficiency of solar power generation in this region.
