Solar PV Analysis of Bucheon-si, South Korea
Bucheon-si, South Korea has a decent potential for generating electricity using solar power throughout the year. The energy generation from solar panels varies with seasons due to changes in sunlight intensity and duration of daylight. During summer and spring, when days are longer, you can expect more energy production - around 5.53 kWh/day and 5.35 kWh/day respectively per kW of installed solar. In autumn and winter, when days are shorter, the output drops to about 3.73 kWh/day and 2.95 kWh/day respectively.
Therefore, if you're considering installing solar panels in Bucheon-si, it would be most effective during spring or summer months as these periods have high sun exposure that leads to greater energy production.
For fixed panel installations at this location, tilting the panels at an angle of 34 degrees towards the south is ideal for maximizing total year-round production from solar PV because it helps capture maximum sunlight throughout different times of the day across all seasons.
As far as environmental factors are concerned that could impede solar production at this location:
- South Korea experiences monsoon season during summer which brings heavy rainfall and cloudy conditions reducing sun exposure.
- Winter season often comes with snowfall which may cover up your panels thus blocking sunlight.
To counteract these issues:
- Regular maintenance should be carried out especially during monsoon season to clean off any debris or water that might accumulate on the surface of your panels.
- During winter months consider installing a system to remove snow from your panels or ensure they can be easily accessed for manual cleaning.
Remember though even under less than ideal weather conditions; well-installed & maintained solar systems will still generate significant amounts of electricity over time!
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 Bucheon-si
Seasonal solar PV output for Latitude: 37.4987, Longitude: 126.7828 (Bucheon-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 34° South in Bucheon-si, South Korea
To maximize your solar PV system's energy output in Bucheon-si, South Korea (Lat/Long 37.4987, 126.7828) 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 Bucheon-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 Bucheon-si, 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 | 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 Bucheon-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 Bucheon-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 Bucheon-si, South Korea
Bucheon-si is located in the western part of South Korea, near Seoul. The topography of this area is characterized by flat plains with some hilly regions. It's a densely populated urban area with numerous buildings and infrastructure.
For large-scale solar PV installations, open and flat areas are ideal as they allow for maximum exposure to sunlight. However, given Bucheon-si's urban character, it may be challenging to find vast open spaces suitable for large-scale solar farms.
Instead, rooftop solar installations could be an excellent option in this region. Many buildings in the city could potentially host photovoltaic panels on their rooftops. This not only saves space but also reduces transmission losses since the electricity doesn't have to travel far from where it's generated.
Alternatively, if looking for larger scale projects outside the city limits - areas towards west or south-west like Seosin-myeon or Hwaseong-si offer more rural landscapes which might be more suitable due to lesser building density and more available land space.
Another potential location could be reclaimed lands along the coast which are relatively flat and receive ample sunlight.
It should also take into account local regulations regarding renewable energy projects as well as any potential environmental impact assessments needed before installation can begin.
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.
