Solar PV Analysis of Dong-gu, South Korea
Dong-gu, Busan, South Korea is a fairly good location for solar energy production year-round. The highest electricity output from solar power would be in the spring and summer seasons, with around 5.3 kWh/day per kW of installed solar panels. During autumn and winter, you can still generate electricity but at a lower rate of about 3.67kWh/day and 3.25kWh/day respectively.
To get the most out of your solar panels in Dong-gu throughout the year, it's best to tilt them towards the south at an angle of 32 degrees. This position will help maximize exposure to sunlight over all four seasons.
There could be some factors that might affect how much energy your solar panels produce in this area though. For example, weather conditions such as fog or heavy cloud cover could limit sunlight exposure on some days which could reduce your overall output.
In terms of environmental factors, if there are tall buildings or trees that cast shadows on your panels during certain times of day or year, this could also impact how much energy you're able to generate.
When installing solar panels in Dong-gu or any similar locations with these potential issues, it's important to consider ways to mitigate them as much as possible for greater efficiency:
1) Choose a spot where there’s minimal shading from nearby structures or vegetation.
2) Regular cleaning can help ensure maximum light absorption especially if dust accumulation is common.
3) Install more than one panel so they can capture sunrays even when others may be shaded.
4) Use high-quality equipment designed to withstand local climate conditions.
Remember that while these strategies can improve performance under less-than-ideal circumstances; nothing beats direct sunlight for optimal renewable energy generation from PV systems!
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 117 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 Dong-gu
Seasonal solar PV output for Latitude: 35.1442, Longitude: 129.0404 (Dong-gu, 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 Dong-gu, South Korea
To maximize your solar PV system's energy output in Dong-gu, South Korea (Lat/Long 35.1442, 129.0404) 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 Dong-gu, 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 Dong-gu, 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 |
|---|---|---|---|
| 19° South in Summer | 41° South in Autumn | 50° South in Winter | 28° 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 Dong-gu, 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 Dong-gu, 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 Dong-gu, South Korea
Dong-gu is located in the city of Busan, South Korea. The topography is mostly urban with a mix of flat and hilly areas. It's characterized by its coastal location on the Sea of Japan (East Sea), with several hills and mountains nearby.
For large-scale solar PV installations, flat open spaces are usually ideal to maximize exposure to sunlight. However, hilly or mountainous areas can also be suitable if they face towards the sun (south in the Northern hemisphere) and aren't shaded by other features.
In Dong-gu's case, potential locations for large-scale solar PV might include:
1. Flat open spaces: These could be existing unused land or repurposed sites within the urban area.
2. Rooftops: Large buildings such as factories or warehouses may have substantial rooftop space that could host solar panels.
3. Coastal areas: If local regulations permit it, parts of the coastline might be suitable for solar installations.
4. Hill slopes facing southwards: These can capture significant sunlight but would require careful design to ensure stability and avoid environmental impact.
It should be noted that all these options would need a detailed feasibility study considering factors like local climate conditions, grid connectivity requirements, social impact considerations etc., before deciding on any specific site for large-scale solar PV installation.
Also consider that South Korea has ambitious renewable energy targets so there may already be plans underway for such projects in this region which can affect availability of suitable sites.
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.
