Solar PV Analysis of Yangju, South Korea
Yangju, South Korea has a decent potential for solar energy production throughout the year. The amount of electricity that can be produced from solar panels varies with each season. In Summer and Spring, the output is quite high at 5.36kWh/day and 5.17kWh/day respectively per kW of installed solar, making these seasons ideal for generating solar power in this location.
In Autumn and Winter, the output drops to 3.63kWh/day and 2.98kWh/day respectively per kW of installed solar due to shorter daylight hours and less intense sunlight during these seasons.
To get the most out of your solar panels in Yangju all year round, it's recommended that you tilt them at an angle of 34 degrees facing south. This is because this angle maximises exposure to sunlight across all four seasons which results in higher total annual power production.
However, there are certain local factors that could potentially affect your ability to generate electricity through solar panels in Yangju:
1) Weather: The area experiences monsoon rains primarily during summer which might reduce sun exposure on some days.
2) Air pollution: Dust or smog can block sunlight from reaching your panels effectively reducing their efficiency
3) Shading: Buildings or trees around your property may cast shadows on your panel hindering its performance
To mitigate these issues:
1) Regular cleaning of the panels especially after heavy rain or dust storms will ensure maximum efficiency
2) Installations should consider possible shading effects; if possible install them where they won't be shaded by nearby structures or vegetation
3) Monitoring system performance regularly will help identify any issues early ensuring optimal operation
Overall Yangju offers quite good conditions for producing energy via Solar PV systems particularly during spring and summer months but also moderately well during autumn and winter.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 124 locations across South Korea. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Yangju
Seasonal solar PV output for Latitude: 37.8344, Longitude: 127.0615 (Yangju, 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 Yangju, South Korea
To maximize your solar PV system's energy output in Yangju, South Korea (Lat/Long 37.8344, 127.0615) 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 Yangju, 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 Yangju, 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 Yangju, 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 Yangju, 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 Yangju, South Korea
Yangju, South Korea is located in the northwest part of the country. The topography of this region is characterized by a mix of flat plains and hilly terrains with some mountainous areas. This area features both urbanized zones (with buildings, roads, etc.) and rural zones (with farms, forests etc.).
In terms of suitability for large-scale solar PV installations, it would depend on several factors including sunlight exposure, land availability and local regulations among others. Typically though:
1) Flat plains: These areas are typically most suitable for large scale solar PV installations due to minimal shading and ease of installation.
2) Rooftops in urbanized zones: Large rooftops such as those found on industrial buildings can also be suitable for solar panel installation.
3) Mountainous or hilly regions: While these may not be ideal due to potential shading and difficulty in installation, south-facing slopes could still potentially be used.
4) Farmlands: Depending on local regulations and farming practices, some farmlands could potentially host dual-use solar installations where agriculture activities continue under elevated solar panels.
However specific suitability would need a detailed site assessment considering all relevant factors.
South Korea solar PV Stats as a country
South Korea ranks 8th in the world for cumulative solar PV capacity, with 18,161 total MW's of solar PV installed. This means that 3.80% of South Korea's total energy as a country comes from solar PV (that's 21st in the world). Each year South Korea is generating 350 Watts from solar PV per capita (South Korea ranks 9th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in South Korea?
Yes, there are incentives for businesses wanting to install solar energy in South Korea. The Korean government offers a variety of financial incentives and subsidies for businesses that install solar energy systems. These include tax credits, grants, loans, and other forms of support. Additionally, the government has implemented a feed-in tariff system which guarantees a fixed price for electricity generated from renewable sources such as solar power. This helps to make the installation of solar energy systems more attractive to businesses by providing them with a guaranteed return on their investment.
