Le Kram, Tunis Governorate, Tunisia presents a moderately favorable location for year-round solar PV energy generation, though with significant seasonal variations that potential installers should carefully consider.

Seasonal Energy Production Patterns

The solar energy output at this Northern Temperate Zone location shows substantial fluctuation throughout the year. Summer delivers the highest production at 7.34 kWh per day per kW of installed capacity, making it an excellent period for solar generation. Spring follows as the second-best season with 5.98 kWh per day per kW, providing strong energy yields during this period. Autumn sees a notable decline to 4.02 kWh per day per kW, while winter presents the most challenging conditions with only 3.01 kWh per day per kW of production. This winter figure represents less than half of the summer output, indicating that energy storage or grid-tied systems would be essential for consistent year-round power supply.

Optimal Panel Configuration

For maximum year-round energy production at Le Kram, Tunis Governorate, fixed solar panels should be tilted at 32 degrees facing south. This angle has been calculated to optimize total annual output by accounting for the sun's varying position throughout the year and weighting the angles based on actual solar irradiance data.

Environmental and Weather Challenges

Several local factors could potentially impact solar production efficiency at this coastal Tunisian location:

• Saharan dust storms can deposit fine sand particles on solar panels, significantly reducing their efficiency
• Mediterranean coastal humidity may lead to salt accumulation on panel surfaces
• Occasional sirocco winds can carry additional dust and debris
• High summer temperatures can reduce panel efficiency despite increased sunlight

Preventative Measures for Optimal Performance

To maximize energy production despite these challenges, several installation strategies should be considered:

• Install automated cleaning systems or schedule regular professional panel cleaning, particularly during dust storm seasons
• Use anti-soiling coatings on panels to reduce dust adhesion and make cleaning more effective
• Ensure adequate ventilation around panels to minimize heat buildup and maintain efficiency
• Consider ground-mounted systems with easy access for maintenance rather than difficult-to-reach roof installations
• Install monitoring systems to quickly identify when cleaning or maintenance is needed

Regular maintenance becomes particularly crucial during the high-production summer months when dust accumulation could significantly impact the season's peak generating potential. The coastal location, while beneficial for cooling breezes, requires vigilance against salt corrosion of mounting hardware and electrical connections.

Solar output per kW of installed solar PV by season in Le Kram

Seasonal solar PV output for Latitude: 36.8394, Longitude: 10.3192 (Le Kram, Tunisia), 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 32° South in Le Kram, Tunisia

To maximize your solar PV system's energy output in Le Kram, Tunisia (Lat/Long 36.8394, 10.3192) throughout the year, you should tilt your panels at an angle of 32° 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 Le Kram, Tunisia

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 Le Kram, Tunisia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° 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	41° South in Autumn	52° South in Winter	29° 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 Le Kram, Tunisia

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 Le Kram, Tunisia.

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 Le Kram, Tunisia

Topography of Le Kram and Surrounding Region

Le Kram sits within the greater Tunis metropolitan area along Tunisia's Mediterranean coastline, positioned on relatively flat to gently undulating terrain that characterizes much of the coastal plain surrounding the capital. The landscape here forms part of the broader Tunis-Bizerte corridor, a low-lying region that extends inland from the Gulf of Tunis. Elevations in the immediate vicinity rarely exceed 50 meters above sea level, creating a predominantly level topography that slopes gradually toward the Mediterranean Sea to the northeast. The terrain consists primarily of sedimentary formations typical of North Africa's coastal regions, with occasional low hills and ridges breaking up the otherwise flat expanse. These gentle rises in elevation are remnants of ancient geological processes and erosion patterns that have shaped the area over millennia. The soil composition includes a mixture of alluvial deposits and Mediterranean terra rossa, creating a landscape that transitions from urban development near the coast to agricultural lands further inland. Water features play a significant role in defining the local topography. The Lac de Tunis, a large shallow lagoon, lies to the southwest of Le Kram, while several seasonal watercourses drain the surrounding hills during the wetter months. These waterways have carved subtle valleys and depressions into the landscape, though none create dramatic elevation changes that would significantly impact large-scale development projects.

Optimal Areas for Large-Scale Solar Development

The topographical characteristics of the Le Kram region present several advantageous areas for substantial solar photovoltaic installations. The most promising locations lie inland from the immediate coastal zone, where the terrain opens up into expansive flat areas with minimal elevation variation. These inland plains offer the dual benefits of stable, level ground for construction while maintaining sufficient distance from the more densely populated coastal settlements. Areas stretching southwest and southeast of Le Kram present particularly favorable conditions. The terrain in these directions consists of broad, relatively featureless expanses that would accommodate large arrays without requiring extensive grading or earthwork. The gentle southward-facing slopes that occasionally interrupt the flat landscape could actually enhance solar collection efficiency while maintaining the structural advantages of stable, well-drained ground. The region's proximity to existing electrical infrastructure represents another significant advantage. The established power grid serving the Tunis metropolitan area extends throughout much of the surrounding territory, reducing the infrastructure investment required to connect large-scale solar installations to the national electricity network. The relatively short distances to major population centers also minimize transmission losses, making power distribution more efficient. Agricultural areas located 10 to 20 kilometers inland from Le Kram offer some of the most suitable terrain for extensive solar development. These locations combine favorable topographical features with lower land values compared to coastal properties, while remaining accessible via the region's established road network. The terrain in these areas typically consists of gently rolling agricultural land that could be readily converted to solar use without significant environmental disruption. The absence of major topographical obstacles such as steep hills, deep valleys, or extensive wetlands throughout much of the inland region creates opportunities for developing solar farms of considerable scale. This relatively uniform terrain allows for standardized installation techniques and reduces the complexity and cost associated with adapting solar arrays to challenging geographical features.
