Seongdong-gu, South Korea, is a fairly good location for generating solar energy year-round. The amount of electricity you can produce from solar panels changes with the seasons. In summer and spring, you can expect to generate about 5.36 and 5.17 kilowatt-hours (kWh) per day for each kilowatt (kW) of solar panel installed respectively, which is pretty high output. While in autumn and winter it drops to around 3.63 kWh/day and 2.98 kWh/day respectively.

This means that the best times of year to generate solar power at this location would be during spring and summer when sunlight hours are longer compared to other seasons.

However, keep in mind that these figures are based on having your panels tilted at an angle of 34 degrees towards the south side - this is considered as the ideal angle for maximum overall yearly production from your panels in Seongdong-gu.

Now let's talk about local factors that might affect solar production here:

South Korea has a monsoon season which usually starts in late June through July where heavy rainfall could decrease sunlight exposure on your panels potentially reducing their output during those periods.

In addition, air pollution or smog often observed in urban areas like Seoul could also hinder sunlight reaching your panels thereby affecting their efficiency.

Preventive measures against these issues include regular cleaning & maintenance of your panels especially after dust storms or heavy rainfalls ensuring they remain clear from debris or pollutants so they can absorb as much sunlight as possible throughout the year.

Also consider installing tracking systems that adjust panel angles according to sun’s position maximizing exposure even under less than ideal weather conditions although this may increase installation costs but could improve overall performance.

Lastly always ensure proper installation by professionals who would take into account all relevant factors including shading from nearby buildings or trees ensuring optimal placement for maximum productivity 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 Seongdong-gu

Seasonal solar PV output for Latitude: 37.5639, Longitude: 127.0188 (Seongdong-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:

Average 5.36kWh/day in Summer.

Average 3.63kWh/day in Autumn.

Average 2.98kWh/day in Winter.

Average 5.17kWh/day in Spring.

Ideally tilt fixed solar panels 34° South in Seongdong-gu, South Korea

To maximize your solar PV system's energy output in Seongdong-gu, South Korea (Lat/Long 37.5639, 127.0188) 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.

At Latitude: 37.5639, Longitude: 127.0188, the ideal angle to tilt panels is 34° South

Seasonally adjusted solar panel tilt angles for Seongdong-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 Seongdong-gu, South Korea. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.

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 Seongdong-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 Seongdong-gu, South Korea.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Seongdong-gu, South Korea

Seongdong-gu is located in the northeastern part of Seoul, South Korea. The topography of Seongdong-gu is largely urban with a mix of residential and commercial buildings. It's not mountainous but rather flat with slight undulations, typical for an urban area.

The Han River flows to the south of Seongdong-gu providing some open space. However, this area may not be suitable for large-scale solar PV installations due to its recreational use and potential environmental impact.

For large-scale solar PV projects, you would ideally look for open spaces with minimal shade and obstruction from surrounding structures or vegetation. Given the dense urban nature of Seongdong-gu, it would be challenging to find such areas within the district itself.

However, there are opportunities for smaller scale distributed solar generation on rooftops of buildings throughout Seongdong-gu which could collectively add up to a significant capacity. Also considering South Korea's push towards renewable energy sources, government incentives might be available for such initiatives.

For larger scale projects nearby regions outside Seoul city that have more open land available could be considered like Gyeonggi province which surrounds Seoul metropolitan area or even further east towards Gangwon province where topography becomes more hilly and less densely populated.

Keep in mind that feasibility also depends on factors like local regulations regarding land use and renewable energy projects as well as grid connectivity issues among others.

Please note that this information should serve as a starting point only; detailed site surveys will need to be conducted before deciding upon any location for setting up solar PV installations.

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.
