Solar PV Analysis of Uiwang, South Korea
The location at Uiwang, South Korea is moderately ideal for generating energy via solar panels throughout the year. In simpler terms, it means that you can use solar panels to generate electricity effectively in this area but there are better and worse times of the year to do so.
During Summer and Spring, the output of electricity from solar panels is higher with 5.53 kilowatt-hours (kWh) per day in Summer and 5.35 kWh/day in Spring for each kilowatt (kW) of installed solar panel capacity. This means that these seasons are more ideal or perfect for generating solar energy because longer daylight hours and greater sun intensity result in more power production.
In contrast, Autumn and Winter have lower output levels with 3.73 kWh/day in Autumn and 2.95 kWh/day in Winter per kW of installed solar panel capacity. These seasons are less ideal due to shorter daylight hours and lower sun intensity which results in less power production.
To maximize total year-round production from your installed solar panels at this location, you should tilt them at an angle of 33 degrees facing towards the South as this will allow them to capture as much sunlight as possible throughout all four seasons.
There might be some local factors such as weather conditions or environmental issues that could affect your ability to generate electricity using your solar panels here too though. For example, if Uiwang experiences heavy snowfall during winter months then snow accumulation on your panels can block sunlight reducing their effectiveness substantially until cleared off again; similarly if there's a lot of air pollution or dust floating around it could also reduce sunlight reaching your panels affecting their efficiency negatively.
Preventative measures like installing a mechanism to automatically clear off any accumulated snow from your panel surfaces during winter months or regular cleaning maintenance schedule throughout all four seasons especially when air pollution levels are high can help ensure greater energy production from your installed system despite these potential challenges faced locally here potentially impeding your solar production.
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 Uiwang
Seasonal solar PV output for Latitude: 37.3965, Longitude: 126.978 (Uiwang, 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 Uiwang, South Korea
To maximize your solar PV system's energy output in Uiwang, South Korea (Lat/Long 37.3965, 126.978) 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 Uiwang, 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 Uiwang, 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 |
|---|---|---|---|
| 21° 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 Uiwang, 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 Uiwang, 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 Uiwang, South Korea
Uiwang is located in the northwestern part of South Korea, near the capital city of Seoul. The area around Uiwang is characterized by a mix of urban development and hilly terrain. There are several small mountains nearby, including Cheonggyesan and Gwanaksan.
The topography varies from flat in the urban areas to steep slopes on the mountainsides. This variation could potentially provide opportunities for solar PV installations.
In terms of large-scale solar PV installations, flatter areas would be more suitable as they require less site preparation and are easier to install panels on. However, these flat areas in this region are mostly occupied by urban development or agriculture.
One potential solution could be building solar farms on reclaimed land or unused industrial sites within the city limits. Another option would be installing solar panels on rooftops throughout the city.
For mountainous regions like Cheonggyesan and Gwanaksan, while it may not be feasible to install large-scale ground-mounted systems due to slope stability issues and accessibility challenges, smaller distributed generation systems such as rooftop or building-integrated photovoltaics might still work depending upon their orientation (south-facing slopes would be ideal).
In addition, floating solar farms could also be considered if there are any suitable water bodies nearby since they do not require any land space at all.
Therefore, identifying specific locations for large-scale solar PV requires a detailed analysis considering various factors such as sun exposure (solar irradiance), land use restrictions, environmental impact assessment etc., along with topographical considerations.
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.
