The location in Daedeok-gu, Daejeon, South Korea, situated at latitude 36.3653 and longitude 127.4405, offers a moderately favorable environment for solar PV energy generation throughout the year. This Northern Temperate Zone location experiences distinct seasonal variations in solar energy production.

Seasonal Solar Performance

Summer stands out as the peak season for solar energy generation, with an impressive 5.36 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, producing 5.18 kWh/day. These seasons present ideal conditions for maximizing solar energy output.

Autumn sees a noticeable decrease in production, yielding 3.70 kWh/day. Winter experiences the lowest output at 3.01 kWh/day, which is still a respectable amount considering the shorter days and lower sun angle during this season.

Optimal Panel Installation

For fixed panel installations at this location, the ideal tilt angle to maximize year-round solar production is 33 degrees facing South. This angle has been calculated to optimize energy capture across all seasons, taking into account the Earth's elliptical orbit and the site's specific latitude.

Environmental Considerations

While Daedeok-gu generally provides favorable conditions for solar energy production, there are some environmental factors to consider:

• Seasonal monsoons: Heavy rainfall during the summer monsoon season could temporarily reduce solar output.
• Air pollution: Being part of a larger urban area, air pollution might occasionally impact solar efficiency.

To mitigate these factors, consider installing panels with anti-soiling coatings to reduce the impact of dust and pollutants. Additionally, implementing a regular cleaning schedule, especially after heavy rains or dusty periods, can help maintain optimal performance.

Overall, Daedeok-gu presents a good location for solar PV energy generation, with strong performance in spring and summer, and reasonable output even during the less favorable autumn and winter months. With proper installation and maintenance, solar panels in this location can provide a reliable source of renewable energy throughout the year.

Solar output per kW of installed solar PV by season in Daedeok-gu

Seasonal solar PV output for Latitude: 36.3653, Longitude: 127.4405 (Daedeok-gu, 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 Daedeok-gu, South Korea

To maximize your solar PV system's energy output in Daedeok-gu, South Korea (Lat/Long 36.3653, 127.4405) 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 Daedeok-gu, 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 Daedeok-gu, 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 Daedeok-gu, 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 Daedeok-gu, 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 Daedeok-gu, South Korea

Daedeok-gu, located in the city of Daejeon, South Korea, is characterized by a diverse topography that combines urban landscapes with natural features. The area is situated in a basin surrounded by low mountains and hills, creating a unique blend of flat land and gentle slopes. To the north and east of Daedeok-gu, the terrain gradually rises into the foothills of the Charyeong Mountain Range. These hills provide a scenic backdrop to the district and offer some protection from harsh winds. The western and southern parts of Daedeok-gu are relatively flatter, with some areas of gently rolling terrain. The Gapcheon River flows through the southern part of Daedeok-gu, creating a natural boundary and adding to the area's topographical diversity. This river valley provides some flat land along its banks, which transitions into slightly elevated areas as you move away from the water.

Potential for Solar PV Installation

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 ample sunlight exposure, relatively flat terrain, and minimal obstruction from natural or man-made structures. The flatter areas to the west and southwest of Daedeok-gu present promising potential for solar PV development. These regions typically have fewer tall buildings and natural obstacles that could cast shadows on solar panels. The gently sloping terrain in these areas could also be advantageous, as it allows for optimal panel positioning to capture sunlight throughout the day. Some of the elevated areas on the outskirts of Daedeok-gu, particularly those facing south, could also be suitable for solar installations. These locations might benefit from increased sun exposure due to their elevation and orientation. However, careful planning would be necessary to ensure that the steeper slopes don't complicate construction or maintenance. It's worth noting that while the immediate vicinity of Daedeok-gu is largely urbanized, venturing slightly further out into the surrounding rural areas of Daejeon could provide more expansive, open spaces ideal for large-scale solar projects. These areas often have the advantage of lower land costs and fewer zoning restrictions compared to more densely populated urban zones. In conclusion, while Daedeok-gu itself may have limited space for large-scale solar PV due to its urban nature, the surrounding regions offer promising potential. The combination of flat lands to the west and south, along with some strategically chosen elevated areas, could provide suitable locations for significant solar energy development in the vicinity of Daedeok-gu.
