Kuacjok, Warrap, South Sudan, situated at latitude 8.3028 and longitude 27.98, presents a promising location for solar energy generation throughout the year. This tropical region experiences consistent sunlight and is characterized more by wet and dry seasons rather than traditional four-season cycles.

Solar Energy Potential

The solar energy potential in Kuacjok is remarkably stable across all meteorological seasons. Spring yields the highest output at 6.85 kWh per day for each kilowatt of installed solar capacity, closely followed by winter at 6.66 kWh/day. Autumn and summer produce 6.14 kWh/day and 5.80 kWh/day, respectively. This consistency is advantageous for year-round energy production, with only minor fluctuations between seasons.

Optimal Panel Tilt

For fixed panel installations in Kuacjok, Warrap, the ideal tilt angle to maximize year-round solar production is 8 degrees facing South. This relatively low tilt angle is due to the location's proximity to the equator, where the sun's path is more directly overhead throughout the year.

Environmental Considerations

While Kuacjok's location is generally favorable for solar energy production, there are some environmental factors to consider: 1. Dust and sand: The region's dry seasons can lead to dust accumulation on solar panels, potentially reducing efficiency. 2. Heavy rainfall: During the wet season, intense rainstorms could temporarily reduce solar output. To mitigate these issues, regular panel cleaning should be incorporated into maintenance routines. Additionally, installing panels at the recommended 8-degree tilt can help with natural cleaning during rainfalls and prevent dust buildup.

Conclusion

Overall, Kuacjok's location is highly suitable for solar PV installations. The consistent year-round sunlight and minimal seasonal variations in energy output make it an ideal site for solar energy production. With proper installation and maintenance practices, solar panels in this location can provide a reliable and efficient source of renewable energy throughout the year.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 8 locations across South Sudan. 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 Kuacjok

Seasonal solar PV output for Latitude: 8.3028, Longitude: 27.98 (Kuacjok, South Sudan), 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 8° South in Kuacjok, South Sudan

To maximize your solar PV system's energy output in Kuacjok, South Sudan (Lat/Long 8.3028, 27.98) throughout the year, you should tilt your panels at an angle of 8° 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 Kuacjok, South Sudan

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 Kuacjok, South Sudan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 8° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
7° North in Summer	15° South in Autumn	24° South in Winter	2° 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 Kuacjok, South Sudan

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 Kuacjok, South Sudan.

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 Kuacjok, South Sudan

The topography around Kuacjok, South Sudan, is characterized by a relatively flat landscape with gentle undulations. This area is part of the vast Sudd wetland region, which is known for its expansive floodplains and grasslands. The terrain is primarily composed of savanna and grasslands, with scattered trees and shrubs dotting the landscape.

The elevation in and around Kuacjok is generally low, ranging from about 400 to 500 meters above sea level. The area experiences a gradual slope towards the north and east, where it eventually meets the White Nile River system. Seasonal streams and small rivers crisscross the region, contributing to the periodic flooding that occurs during the rainy season.

As for areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, several factors need to be considered. The ideal locations would be:

1. Flat or gently sloping areas: These are abundant in the region surrounding Kuacjok, making it relatively easy to find suitable sites for solar panel arrays.
2. Areas with minimal vegetation: While the savanna landscape does have trees and shrubs, there are many open grassland areas that would require less clearing for solar installations.
3. Locations away from flood-prone zones: It would be crucial to avoid low-lying areas near rivers or seasonal streams that are susceptible to flooding during the rainy season.
4. Proximity to existing infrastructure: Areas closer to Kuacjok or other settlements with road access and potential grid connections would be more practical for large-scale solar projects.

The regions to the south and west of Kuacjok might be particularly suitable for solar PV installations, as they tend to be slightly more elevated and less prone to flooding compared to the areas closer to the Nile system in the north and east. However, a detailed site survey would be necessary to determine the most appropriate locations, taking into account factors such as soil stability, local weather patterns, and environmental considerations.
