Haeundae-gu, located in Busan, South Korea, presents a moderately favorable location for solar PV energy generation throughout the year. Situated in the Northern Temperate Zone at coordinates 35.1692° N, 129.1738° E, this coastal area experiences distinct seasonal variations in solar energy production.

Seasonal Solar Energy Output

The solar energy output in Haeundae-gu fluctuates across the four meteorological seasons. Spring and summer are 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 decrease to 3.67 kWh/day, while winter experiences the lowest output at 3.25 kWh/day.

The most ideal times for solar energy generation in this location are from late spring through early autumn, typically spanning from April to September. During these months, longer daylight hours and generally clearer skies contribute to higher solar panel efficiency.

Optimal Panel Installation

For fixed panel installations in Haeundae-gu, the ideal tilt angle to maximize year-round solar production is 32 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the location's latitude and the Earth's elliptical orbit.

Environmental and Weather Factors

Several environmental and weather factors can impact solar energy production in Haeundae-gu:

1. Monsoon season: The region experiences a summer monsoon, typically from June to early September, which can lead to increased cloud cover and rainfall, potentially reducing solar output.
2. Typhoons: As a coastal area, Haeundae-gu is susceptible to typhoons, usually occurring between July and September, which can cause temporary reductions in solar generation.
3. Air pollution: Busan, like many large urban areas in South Korea, can experience air pollution, which may slightly reduce solar panel efficiency.

Preventative Measures

To mitigate these factors and ensure greater energy production, consider the following measures when installing solar panels:

• Use high-quality, weather-resistant panels designed to withstand heavy rainfall and strong winds.
• Install a robust mounting system capable of enduring typhoon-force winds.
• Implement a regular cleaning schedule to remove pollution buildup and maximize panel efficiency.
• Consider microinverter or power optimizer technology to minimize the impact of partial shading on overall system performance.

By taking these precautions, solar PV installations in Haeundae-gu can maintain optimal performance despite occasional challenging weather conditions and environmental factors.

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 Haeundae-gu

Seasonal solar PV output for Latitude: 35.1692, Longitude: 129.1738 (Haeundae-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 32° South in Haeundae-gu, South Korea

To maximize your solar PV system's energy output in Haeundae-gu, South Korea (Lat/Long 35.1692, 129.1738) 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 Haeundae-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 Haeundae-gu, 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	50° 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 Haeundae-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 Haeundae-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 Haeundae-gu, South Korea

The topography around Haeundae-gu, South Korea, is characterized by a diverse landscape that combines coastal features with urban development and nearby mountainous terrain. Located on the southeastern coast of the Korean Peninsula, Haeundae-gu is primarily known for its famous beach and bustling city life. The area immediately surrounding Haeundae-gu is relatively flat, with the iconic Haeundae Beach stretching along the coastline. This sandy beach is bordered by a mix of high-rise buildings and tourist facilities. Moving inland, the terrain gradually rises, transitioning into low hills and eventually more significant elevations. To the north and northwest of Haeundae-gu, the landscape becomes more rugged, with several mountains dominating the skyline. The most prominent of these is Jangsan Mountain, which rises to an elevation of about 634 meters above sea level. This mountainous region is part of a larger chain that runs along the eastern coast of South Korea.

Potential Areas for Large-scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would offer ample space, minimal shading, and good sun exposure throughout the day. The densely populated urban areas of Haeundae-gu itself are not well-suited for large-scale solar PV due to limited available space and potential shading from buildings. However, some potential areas in the vicinity could be considered: 1. The flatter regions to the west and southwest of Haeundae-gu, towards Suyeong-gu and parts of Geumjeong-gu, might offer suitable locations. These areas have less dramatic elevation changes and could potentially accommodate larger installations. 2. The gently sloping hillsides to the north and northwest, leading up to the mountains, could be considered if they are not heavily forested or protected as natural reserves. South-facing slopes would be particularly advantageous for maximizing solar exposure. 3. Reclaimed land or industrial areas along the coast, particularly to the west near Suyeong Bay, might provide opportunities for solar installations if not already designated for other uses. It's important to note that any large-scale solar PV project would need to carefully consider environmental impacts, local regulations, and land-use policies. The proximity to the urban area of Busan could be advantageous for power distribution but might also present challenges in terms of available space and competing land uses.
