Haenam-gun, South Korea, located in the Northern Sub Tropics at coordinates 34.5711, 126.601, presents a generally favorable environment for solar PV energy generation throughout the year. The location experiences varying levels of solar productivity across the four meteorological seasons.

Seasonal Solar Performance

Summer and spring stand out as the most productive seasons for solar energy generation in Haenam-gun. During summer, solar panels can be expected to produce an impressive 5.60 kWh per day for each kW of installed capacity. Spring follows closely behind with 5.59 kWh/day per kW. These seasons offer ideal conditions for maximizing solar energy output.

Autumn sees a moderate decrease in productivity, with panels generating an average of 3.78 kWh/day per kW. Winter experiences the lowest output, with 2.86 kWh/day per kW. Despite the reduced performance during colder months, the overall year-round production remains relatively consistent, making Haenam-gun a suitable location for solar PV installations.

Optimal Panel Positioning

For fixed panel installations in Haenam-gun, the ideal tilt angle to maximize total year-round production is 31 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.

Environmental Considerations

While Haenam-gun generally offers favorable conditions for solar energy production, there are some environmental factors to consider:

• Typhoons: The region can experience typhoons during late summer and early autumn, which may pose a risk to solar installations.
• Air pollution: Occasional periods of high air pollution, including yellow dust from China, can slightly reduce solar panel efficiency.

To mitigate these risks, it's crucial to implement robust mounting systems that can withstand high winds and to schedule regular cleaning of the panels to remove dust and pollutants. Additionally, using high-quality, weather-resistant panels can help ensure consistent performance despite these environmental challenges.

Overall, Haenam-gun's location in the Northern Sub Tropics provides a good balance of solar productivity throughout the year, making it a suitable site for solar PV installations with proper planning and maintenance.

Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Solar output per kW of installed solar PV by season in Haenam-gun

Seasonal solar PV output for Latitude: 34.5711, Longitude: 126.601 (Haenam-gun, 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 31° South in Haenam-gun, South Korea

To maximize your solar PV system's energy output in Haenam-gun, South Korea (Lat/Long 34.5711, 126.601) throughout the year, you should tilt your panels at an angle of 31° 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 Haenam-gun, 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 Haenam-gun, South Korea. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 31° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
18° South in Summer	40° South in Autumn	49° South in Winter	27° 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 Haenam-gun, 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 Haenam-gun, 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 Haenam-gun, South Korea

The topography around Haenam-gun, South Korea, is characterized by a diverse landscape that combines coastal features with inland hills and valleys. Located at the southwestern tip of the Korean Peninsula, this region boasts a mixture of flat coastal plains, gently rolling hills, and some more pronounced elevated areas. Along the coastline, which forms the western and southern boundaries of Haenam-gun, you'll find extensive tidal flats and mudflats. These areas are periodically submerged during high tides and exposed during low tides, creating a dynamic ecosystem. Moving inland, the terrain gradually rises, transitioning into low-lying agricultural plains where rice paddies and other crops are cultivated. As you progress further inland, the landscape becomes more varied, with numerous small hills and valleys dotting the area. These hills are typically not very high, rarely exceeding 300 meters in elevation. However, they provide a pleasant undulating scenery that contrasts with the flatter coastal regions. The hills are often covered with a mix of deciduous and coniferous forests, adding to the area's natural beauty.

Suitability 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 combine ample sunlight exposure, relatively flat terrain, and minimal environmental impact. The coastal plains and low-lying agricultural areas near Haenam-gun present promising opportunities for solar PV development. These regions offer large, open spaces with minimal shading from natural features, allowing for maximum solar exposure throughout the day. The flat terrain also simplifies construction and reduces installation costs. Some of the gently sloping hillsides facing south or southwest could also be suitable for solar farms. These areas benefit from increased sun exposure due to their orientation and may have less agricultural value compared to the fertile lowlands. However, it's important to note that any large-scale solar development would need to carefully consider the potential impact on local agriculture, as the region is known for its farming activities. Additionally, areas close to the coast should be evaluated for potential risks related to sea-level rise and storm surges. Ultimately, the most suitable locations for large-scale solar PV in the Haenam-gun area would likely be a combination of underutilized agricultural land in the coastal plains and carefully selected hillside areas that don't conflict with existing land uses or important ecosystems.
