Solar PV Analysis of Cheonan, South Korea
The location at Cheonan, South Korea is relatively good for generating energy via solar PV year-round. This is based on the amount of electricity that can be expected to be produced from each kW of installed solar in all four seasons. The best times of the year for solar generation at this location are during the Summer and Spring, with 5.36kWh/day and 5.18kWh/day respectively being produced per kW of installed solar. Autumn produces a decent amount too, with 3.70kWh/day per kW, while Winter sees the lowest output with only 3.01kWh/day per kW.
For a fixed panel installation at this location, tilting panels towards an angle of 33 degrees South would maximize total yearly production from solar PVs.
However, there might be environmental or weather-related factors that could impede solar production here; these include heavy rainfalls or snow during winter which may cover panels temporarily reducing their efficiency and air pollution which can reduce sunlight penetration thus lowering efficiency as well.
Preventative measures that could help ensure greater energy production in relation to these factors include regular cleaning and maintenance of panels to remove any dust or debris caused by pollution or bad weather conditions like snowfall or heavy rainfall. Also using high-quality durable panels resistant to harsh weather conditions would also help maintain optimal performance over time.
Additionally, integrating battery storage systems can store excess power generated during peak hours (like summer) which then can be used when production is low (like winter).
In summary, while there are challenges due to environmental and seasonal variations in Cheonan's climate; careful planning including proper panel positioning & maintenance along with efficient storage solutions will make it possible for effective use of Solar PV systems throughout the year.
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 Cheonan
Seasonal solar PV output for Latitude: 36.8151, Longitude: 127.0944 (Cheonan, 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 33° South in Cheonan, South Korea
To maximize your solar PV system's energy output in Cheonan, South Korea (Lat/Long 36.8151, 127.0944) throughout the year, you should tilt your panels at an angle of 33° 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 Cheonan, 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 Cheonan, South Korea. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° 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 | 42° South in Autumn | 52° South in Winter | 30° 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 Cheonan, 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 Cheonan, 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 Cheonan, South Korea
Cheonan is located in the western part of South Korea. The topography of Cheonan is relatively flat with some hilly areas. There are also several mountains surrounding the city, including Taejosan and Gwangdeoksan.
For large-scale solar PV installations, flat or gently sloping land is usually preferred as it reduces installation costs and makes maintenance easier. It's also important to consider factors like sunlight hours and cloud cover when choosing a location for solar power plants.
Given these considerations, the flatter areas around Cheonan would be more suitable for large-scale solar PV installations. However, specific site assessments would need to be done to identify potential locations that have good sun exposure throughout the year and minimal shading from nearby structures or vegetation.
It's worth noting that South Korea has been investing heavily in renewable energy over recent years, with a particular focus on solar power. The country's southern regions tend to receive more sunlight than the northern regions so they might offer better conditions for solar power generation overall. But given its relatively central position within South Korea and its mix of flatlands and hillsides which could potentially harness both ground-mounted systems (in flatter areas) or hillside installations (where appropriate), Cheonan could still present viable options for such developments.
However, this type of project requires extensive planning permission process including environmental impact studies etc., so any potential sites would need careful evaluation before proceeding with development plans.
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.
