Solar PV Analysis of Pyeongtaek-si, South Korea
Pyeongtaek-si, South Korea is a fairly good location for year-round solar energy production. The amount of solar energy you can generate depends on the season. In the summer and spring, you can expect to produce around 5.36 and 5.17 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar power respectively. This means that these seasons are ideal times to harness solar energy in this location because there's more sunlight available.
During autumn, the daily production drops slightly to about 3.63 kWh/day per kW of installed power due to less sunlight hours and lower intensity of sunlight as compared to summer and spring months.
Winter sees the least amount of sun with about 2.98 kWh/day per kW, so it's not as ideal for generating solar power as other seasons but still viable.
To get the most out of your solar panels all year round at this location, they should be tilted at an angle facing towards south by 33 degrees from horizontal direction which captures maximum sunlight throughout different periods in a year.
The local factors that could potentially impede solar production at this location include weather conditions like cloud cover or heavy snowfall during winter which can block sunlight from reaching the panels; air pollution or dust which may settle on panels reducing their efficiency; tall buildings or trees in close proximity causing shading etc.
Preventative measures include regular cleaning & maintenance of panels especially after snowfall or dust storms; installing them away from tall obstacles causing shading; using tracking systems that adjust panel orientation based on sun's position during day time could also increase their productivity but might add extra cost initially during installation phase.
Overall though, Pyeongtaek-si is a decent place for setting up a photovoltaic system with some minor challenges easily mitigated through proper planning and maintenance practices.
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 Pyeongtaek-si
Seasonal solar PV output for Latitude: 37.0009, Longitude: 127.0859 (Pyeongtaek-si, 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 Pyeongtaek-si, South Korea
To maximize your solar PV system's energy output in Pyeongtaek-si, South Korea (Lat/Long 37.0009, 127.0859) 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 Pyeongtaek-si, 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 Pyeongtaek-si, 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 Pyeongtaek-si, 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 Pyeongtaek-si, 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 Pyeongtaek-si, South Korea
Pyeongtaek-si, South Korea is located in the western part of the country and features a mix of flat plains, gentle hills, and coastal areas along the Yellow Sea. The region is primarily urbanized with some agricultural lands interspersed.
For large-scale solar photovoltaic (PV) installations, flat or gently sloping terrains are ideal as they require less groundwork for installation and can accommodate more panels per unit area. In addition to topography, factors such as solar irradiance (amount of sunlight), land availability and use, proximity to grid infrastructure for power transmission also need to be considered.
In Pyeongtaek-si region:
1. Flat Plains: These areas could potentially be suitable for large-scale solar PV installations due to their level topography. However, it would be important to ensure that these lands are not prime agricultural lands or populated residential zones which might have other priority uses.
2. Coastal Areas: While coastal regions receive good sunlight making them attractive for solar PV installations; considerations around land use especially if they are protected natural habitats or used for fisheries etc., salt mist corrosion affecting PV panel performance and durability need careful evaluation.
3. Unused Industrial Lands: If there are any unused industrial lands within Pyeongtaek-si city limits or its outskirts; these could potentially serve as good sites given their proximity to existing grid infrastructure reducing transmission costs.
4. Rooftops: Large commercial buildings or factories with expansive rooftops can also make excellent locations for installing solar panels without requiring additional land space.
A detailed site-specific assessment considering all these factors would provide a more accurate identification of suitable locations for large-scale solar PV in Pyeongtaek-si region.
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.
