Winejok, Northern Bahr al Ghazal, South Sudan, located at 9.0122° N, 27.5708° E, presents a favorable environment for solar energy production throughout the year. This tropical location benefits from consistent sunlight and experiences wet and dry seasons rather than traditional four-season cycles.

Solar Energy Potential

The solar energy output at Winejok is impressive and relatively stable across all seasons. Spring sees the highest production at 6.96 kWh per day for each kilowatt of installed solar capacity. Winter follows closely with 6.56 kWh/day, then autumn with 6.26 kWh/day, and summer with a still-respectable 5.85 kWh/day. These figures indicate that Winejok is an excellent location for year-round solar energy generation. The minimal variation between seasons suggests a reliable and consistent energy supply, which is ideal for both small-scale and large-scale solar installations.

Optimal Panel Positioning

For fixed solar panel installations in Winejok, Northern Bahr al Ghazal, the ideal tilt angle to maximize year-round energy production is 9 degrees facing South. This slight tilt helps to optimize the panels' exposure to sunlight throughout the year, taking into account the location's proximity to the equator and the sun's path across the sky.

Environmental Considerations

While Winejok's location is generally favorable for solar energy production, there are a few environmental factors to consider: 1. Dust and sand: The region's dry seasons may lead to increased dust and sand in the air, which can accumulate on solar panels and reduce their efficiency. 2. Heavy rainfall: During the wet season, intense rainstorms could potentially damage poorly installed solar equipment. To mitigate these issues, several preventative measures can be taken:

Preventative Measures

1. Regular cleaning: Implement a routine cleaning schedule for solar panels to remove dust and sand buildup. 2. Protective coatings: Apply anti-soiling coatings to panel surfaces to reduce dust accumulation and make cleaning easier. 3. Robust mounting systems: Use sturdy, weather-resistant mounting structures to withstand heavy rains and potential wind during storms. 4. Proper drainage: Ensure good drainage around the installation site to prevent water accumulation during the wet season. By implementing these measures, solar installations in Winejok can maintain high efficiency and durability, making the most of the location's excellent solar potential throughout the year.

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

Solar output per kW of installed solar PV by season in Winejok

Seasonal solar PV output for Latitude: 9.0122, Longitude: 27.5708 (Winejok, 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 9° South in Winejok, South Sudan

To maximize your solar PV system's energy output in Winejok, South Sudan (Lat/Long 9.0122, 27.5708) throughout the year, you should tilt your panels at an angle of 9° 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 Winejok, 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 Winejok, South Sudan. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 9° 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	25° South in Winter	3° 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 Winejok, 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 Winejok, 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 Winejok, South Sudan

The topography around Winejok, South Sudan, is characterized by a relatively flat landscape with gentle undulations. This area is part of the vast Sudd wetland region, which is dominated by expansive grasslands and seasonal swamps. The terrain is generally low-lying, with elevations ranging from approximately 400 to 500 meters above sea level. The landscape surrounding Winejok is primarily composed of savanna grasslands interspersed with scattered trees and shrubs. During the rainy season, which typically occurs from May to October, many areas become waterlogged, creating temporary wetlands and shallow pools. In the dry season, the land becomes parched, and the vegetation takes on a golden-brown hue.

Suitability for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The flat terrain around Winejok offers advantages for solar development, as it minimizes the need for extensive land preparation and allows for easier construction and maintenance of solar arrays. The regions to the north and east of Winejok are particularly promising for solar PV projects. These areas tend to have slightly higher elevations and better drainage, reducing the risk of flooding during the rainy season. The open grasslands in these directions provide ample space for large-scale installations without significant obstruction from trees or other vegetation. It's important to note that while the general topography is favorable, site-specific assessments would be necessary to determine the most suitable locations. Factors such as soil stability, accessibility to roads and power infrastructure, and proximity to population centers would need to be considered alongside the topographical features. Additionally, areas slightly elevated above the surrounding plains might be preferred to minimize the risk of seasonal flooding and to ensure optimal exposure to sunlight throughout the year. These elevated areas, even if only a few meters higher than the surrounding landscape, could provide better conditions for solar PV installations by reducing the likelihood of water accumulation and potential damage to equipment. In conclusion, while the entire region around Winejok offers potential for solar PV development due to its generally flat terrain, the areas to the north and east, particularly those with slight elevations, present the most promising opportunities for large-scale solar projects. However, comprehensive environmental and technical surveys would be essential before embarking on any major solar installation in this unique and ecologically sensitive region.
