Koudougou, Burkina Faso, located in the tropics at latitude 12.2526 and longitude -2.3677, offers a favorable environment for solar energy production throughout the year. This location benefits from consistent sunlight and experiences wet and dry seasons rather than the traditional four seasons.

Year-round Solar Potential

The solar energy output at this location remains relatively stable across all seasons, with only minor fluctuations. Spring sees the highest production at 6.91 kWh per day for each kilowatt of installed solar capacity, followed closely by autumn and winter at 6.53 kWh and 6.52 kWh, respectively. Summer experiences a slight dip but still maintains a respectable 5.91 kWh per day. These figures indicate that Koudougou is an excellent location for solar energy production throughout the year. The consistent output across seasons means that solar installations can provide a reliable source of energy without significant seasonal variations.

Optimal Panel Tilt

For fixed solar panel installations in Koudougou, the ideal tilt angle to maximize year-round energy production is 12 degrees facing South. This angle takes into account the location's proximity to the equator and the sun's path throughout the year, ensuring optimal exposure to sunlight.

Environmental and Weather Considerations

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

• Install panels at the recommended 12-degree tilt to promote natural cleaning during rainfall and reduce dust accumulation.
• Implement regular cleaning schedules, especially during dry seasons, to remove dust and maintain optimal panel efficiency.
• Use high-quality, weather-resistant solar equipment designed to withstand tropical conditions.
• Ensure proper drainage systems are in place to prevent water accumulation during heavy rains.

By addressing these factors, solar installations in Koudougou can maintain high levels of energy production throughout the year, taking full advantage of the location's excellent solar potential.

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 4 locations across Burkina Faso. 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 Koudougou

Seasonal solar PV output for Latitude: 12.2526, Longitude: -2.3677 (Koudougou, Burkina Faso), 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 12° South in Koudougou, Burkina Faso

To maximize your solar PV system's energy output in Koudougou, Burkina Faso (Lat/Long 12.2526, -2.3677) throughout the year, you should tilt your panels at an angle of 12° 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 Koudougou, Burkina Faso

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 Koudougou, Burkina Faso. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 12° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
4° North in Summer	18° South in Autumn	28° South in Winter	6° 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 Koudougou, Burkina Faso

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 Koudougou, Burkina Faso.

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 Koudougou, Burkina Faso

The topography around Koudougou, Burkina Faso, is characterized by a relatively flat landscape with some gentle undulations. This area is part of the West African Sahel region, which is a transitional zone between the Sahara Desert to the north and the more humid savannas to the south. The terrain is mostly comprised of low-lying plains with occasional small hills and rocky outcrops.

The elevation in and around Koudougou is generally between 250 to 350 meters above sea level. The land is mostly covered with sparse vegetation, including scattered trees and shrubs adapted to the semi-arid climate. During the dry season, the landscape can appear quite barren, while the rainy season brings a temporary green cover to the area.

As for areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, there are several factors to consider:

1. Flat or gently sloping terrain: The relatively flat landscape around Koudougou is generally favorable for solar PV installations, as it minimizes the need for extensive land preparation and allows for efficient panel placement.

2. Open areas with minimal shading: Regions to the north and west of Koudougou, where vegetation is sparser and there are fewer settlements, could be ideal for solar farms. These areas typically receive less rainfall and have fewer obstructions that could cast shadows on solar panels.

3. Proximity to infrastructure: Areas close to existing roads and power transmission lines would be preferable to reduce the costs of transporting equipment and connecting to the grid. The outskirts of Koudougou, particularly to the east and south, might offer a good balance between open space and access to infrastructure.

4. Land availability: Regions with lower population density and less agricultural activity would be more suitable for large-scale solar projects. This might include areas further from the city center, possibly 10-20 kilometers out in any direction, depending on local land use patterns.

5. Solar irradiance: While the entire region receives abundant sunlight, slight variations in cloud cover and atmospheric conditions might make some areas marginally more suitable than others. Generally, locations further north would receive slightly more solar radiation throughout the year.

In conclusion, while the entire area around Koudougou has potential for solar PV development due to its favorable topography and climate, the most suitable locations would likely be found in the less populated, flatter areas to the north and west of the city, balancing factors such as land availability, infrastructure access, and optimal solar exposure.
