Solar PV Analysis of Gunpo, South Korea
The location at Gunpo, South Korea, is a decent spot for producing energy using solar photovoltaic (PV) technology throughout the year. However, it's not ideal due to seasonal variations.
In simple terms, during Summer and Spring seasons, a solar panel can produce around 5.53 and 5.35 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of installed solar power respectively. This means that these are the best times of the year for generating solar energy in Gunpo as the sun shines more intensely and for longer hours.
On the other hand, in Autumn and Winter seasons, production drops to about 3.73 kWh/day and 2.95 kWh/day per kW respectively because there's less sunlight available due to shorter days and lower sun intensity.
For optimal performance all year round from your solar panels in Gunpo, you should tilt them at an angle of 33 degrees towards South direction which helps capture maximum sunlight over different seasons.
There may be some local factors that could reduce how much electricity your panels generate such as heavy snowfall or dust accumulation on panels during winter season which can block sunlight reaching your panels; air pollution or foggy conditions might also affect visibility reducing overall efficiency; tall buildings or trees nearby might cast shadows on your panels limiting their exposure to direct sunlight among others.
To overcome these challenges: regularly clean your panels especially after heavy snowfall or dust storms; install them away from potential sources of shadow like tall structures or trees if possible; consider using advanced PV modules designed to perform well under low light conditions if air pollution is a significant problem in this area etc.
Remember though that while these measures can help improve performance they cannot entirely eliminate effects of local environmental conditions so always factor them into consideration when planning installation size based on expected output levels.
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 Gunpo
Seasonal solar PV output for Latitude: 37.3666, Longitude: 126.9512 (Gunpo, 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 Gunpo, South Korea
To maximize your solar PV system's energy output in Gunpo, South Korea (Lat/Long 37.3666, 126.9512) 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 Gunpo, 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 Gunpo, 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 Gunpo, 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 Gunpo, 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 Gunpo, South Korea
Gunpo, South Korea is located in the western part of the country and is characterized by a mix of urban areas and hilly terrain. The area does have some flatlands which could potentially be suitable for large-scale solar PV installations.
However, due to its urban nature, rooftop solar installations on commercial and residential buildings may also be a viable option. This would allow for the generation of clean energy without requiring additional land resources.
The nearby regions such as Ansan to the west and Suwon to the east also have similar topography with a mixture of urban development and hilly terrains. They might offer potential locations for large-scale solar PV projects too.
However, an in-depth feasibility study would need to be conducted before any firm decisions can be made about specific sites within these areas. Factors like local climate conditions (cloud cover, fog etc.), land use restrictions or regulations, proximity to electrical grid infrastructure etc., will all need consideration.
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.
