Gunsan, South Korea is a decent location for generating energy through solar power year-round. The amount of electricity that can be generated varies with the seasons, but it's generally quite good.
During summer and spring, you can expect to generate about 5.63kWh and 5.46kWh per day respectively for each kilowatt of solar power installed. This means that these are the best times to generate solar energy as they provide the highest output.
In autumn, the daily output drops slightly to around 3.77kWh per day for each kilowatt installed. Winter sees even less sunlight with an average daily output of only about 2.74 kWh per day for each kilowatt installed.
To get the most out of your solar panels throughout the year in Gunsan, it's ideal to tilt them at an angle of 32 degrees towards south direction because this will allow them to capture more sunlight overall throughout different times in a year.
However, there could be some local factors that might affect how much energy you can produce from your solar panels in Gunsan.
One possible factor could be weather conditions such as heavy rainfall or snowfall which may cover up your panels and reduce their effectiveness. To deal with this issue, one preventative measure would be installing automated cleaning systems or heaters on your panels to keep them clear from dust or snow build-up thus ensuring greater production efficiency.
Another potential problem could come from air pollution if there is any significant level present in Gunsan area which might block some sunlight reaching your panels reducing their effectiveness too; therefore having regular maintenance checks would help ensure optimal performance by keeping them clean and free from dust particles etc.,
So while Gunsan isn't perfect all year round due its seasonal variations in sunlight availability; however with right installation methods and regular maintenance procedures - it still makes a pretty good spot for generating decent amounts of electricity using solar power!
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 Gunsan
Seasonal solar PV output for Latitude: 35.957, Longitude: 126.744 (Gunsan, 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 Gunsan, South Korea
To maximize your solar PV system's energy output in Gunsan, South Korea (Lat/Long 35.957, 126.744) 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 Gunsan, 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 Gunsan, 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 |
|---|---|---|---|
| 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 Gunsan, 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 Gunsan, 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 Gunsan, South Korea
Gunsan is located on the west coast of South Korea in North Jeolla Province. The topography of the area is relatively flat, with some low-lying hills. The city itself is situated on a coastal plain and has several rivers flowing through it, including the Geum River.
The region around Gunsan experiences a temperate climate with four distinct seasons. It gets ample sunlight throughout the year making it suitable for solar PV installations.
As for specific areas suited to large-scale solar PV, there are several factors to consider:
1) Availability of Flat Land: Large-scale solar projects require extensive tracts of flat land. Given that Gunsan's surrounding area is relatively flat, there should be numerous suitable locations provided they are not already heavily developed or used for agricultural purposes.
2) Proximity to Power Grid: Any potential site needs to be close enough to existing power infrastructure for easy connection and transmission.
3) Environmental Impact: Areas that do not have significant wildlife or delicate ecosystems would be preferred so as not to cause unnecessary environmental harm.
4) Legal regulations: Some areas may have restrictions on land use which could affect where a large scale solar project can be built.
Considering these factors, rural areas outside of Gunsan city that aren't actively used for agriculture or habitation might be most suited for large-scale solar PV installations. Also considering its coastal location, offshore floating photovoltaic (FPV) systems could also potentially work well if local regulations allow them.
However, before proceeding with any project an in-depth feasibility study involving local authorities and experts will need to be conducted.
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.
