Optimal Panel Installation

For fixed panel installations in Jeongeup, the ideal tilt angle to maximize year-round solar 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 and Weather Considerations

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

1. Monsoon season: Jeongeup experiences a monsoon season, typically from June to September, which can lead to increased cloud cover and rainfall, potentially reducing solar output.
2. Air pollution: Like many parts of South Korea, Jeongeup may experience periods of high air pollution, including fine dust, which can slightly reduce solar panel efficiency.

To mitigate these challenges, consider implementing the following measures:

• Use high-quality, weather-resistant solar panels designed to perform well in humid conditions.
• Install a robust cleaning system or schedule regular cleaning to combat dust and pollution buildup on panels.
• Implement a monitoring system to track performance and quickly identify any issues related to weather or environmental factors.

Overall, while Jeongeup faces some seasonal and environmental challenges, its location still provides a solid foundation for solar PV energy generation, especially during the spring and summer months.

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 Jeongeup

Seasonal solar PV output for Latitude: 35.5825, Longitude: 126.8676 (Jeongeup, 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 Jeongeup, South Korea

To maximize your solar PV system's energy output in Jeongeup, South Korea (Lat/Long 35.5825, 126.8676) 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 Jeongeup, 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 Jeongeup, 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
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 Jeongeup, 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 Jeongeup, 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 Jeongeup, South Korea

The topography around Jeongeup, South Korea, is characterized by a diverse landscape that combines both flat lowlands and hilly terrain. The city itself is situated in a relatively flat basin, surrounded by gently rolling hills and low mountains. To the west of Jeongeup, the terrain gradually transitions into coastal plains as it approaches the Yellow Sea. These lowland areas are primarily used for agriculture, with rice paddies and other crops dominating the landscape. To the east and northeast of Jeongeup, the terrain becomes more mountainous, with several peaks and ridges forming part of the larger Noryeong Mountain Range. These mountains, while not particularly high by global standards, provide a scenic backdrop to the city and contribute to the region's natural beauty. The hills and mountains are largely covered in forests, which play an important role in the local ecosystem and provide recreational opportunities for residents and visitors alike. Rivers and streams crisscross the area around Jeongeup, with the Dongjin River being one of the most prominent waterways. These water bodies have shaped the landscape over time, creating fertile valleys and floodplains that have long been utilized for agriculture.

Areas Suitable for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Jeongeup, several factors come into play, including available land, sunlight exposure, and proximity to existing infrastructure. Based on the topography of the region, the following areas would likely be most suited for such projects: The flat agricultural lands to the west and southwest of Jeongeup offer promising potential for solar PV installations. These areas benefit from minimal shading due to their open nature and relatively level terrain. The existing agricultural use of the land might need to be considered, but solar farms can sometimes be integrated with certain types of farming activities. Gently sloping hillsides surrounding the city, particularly those facing south or southwest, could also be suitable locations for solar arrays. These areas often receive good sun exposure throughout the day and may be less valuable for other types of development or agriculture. Former industrial sites or brownfields within or near the city limits could be repurposed for solar energy production. These locations often have the advantage of existing infrastructure and proximity to power grids, making them cost-effective options for large-scale solar projects. It's important to note that any large-scale solar PV development would need to be carefully planned and assessed for its environmental impact, taking into account factors such as local wildlife habitats, soil conditions, and potential effects on nearby communities. Additionally, consultation with local authorities and adherence to regional and national regulations would be essential in determining the most appropriate sites for such installations.
