El Kabaria, Tunis Governorate, Tunisia, located in the Northern Temperate Zone at coordinates 36.7602°N, 10.1998°E, presents a moderately favorable location for year-round solar PV energy generation, though with significant seasonal variation in output.

Seasonal Solar Performance

The location demonstrates strong summer performance with peak output of 7.34kWh per day per kW of installed solar capacity during the summer months. Spring provides good secondary production at 5.98kWh/day per kW, making these warmer months the ideal times for solar generation at this site. However, the location shows considerable seasonal decline during cooler months. Autumn production drops to 4.02kWh/day per kW, while winter represents the least productive period with only 3.01kWh/day per kW of installed capacity. For optimal year-round energy capture, solar panels should be installed at a fixed tilt angle of 32 degrees facing south. This angle maximizes total annual production by accounting for the sun's varying elevation throughout the year and weighting the optimal angles by actual solar irradiance potential.

Environmental and Weather Challenges

Several significant local factors could impede solar production at El Kabaria and require careful consideration during installation: Saharan Dust and Sand
Being located in North Africa, this region experiences regular Saharan dust storms and airborne sand particles that can significantly reduce panel efficiency by coating solar surfaces. Dust accumulation can decrease output by 15-25% if left unaddressed. Mediterranean Coastal Conditions
The proximity to the Mediterranean Sea introduces salt air and higher humidity levels, which can accelerate corrosion of mounting hardware and electrical connections over time. Seasonal Weather Patterns
Tunisia experiences occasional heavy rainfall during winter months and potential for strong Mediterranean winds, which could affect panel stability and create temporary shading from storm clouds.

Preventative Installation Measures

To maximize energy production despite these challenges, several protective measures should be implemented:

• Install panels with smooth, anti-reflective glass surfaces that naturally shed dust more easily
• Design mounting systems with adequate spacing between panels to allow wind cleaning action
• Use marine-grade aluminum frames and stainless steel hardware to resist salt corrosion
• Apply protective coatings to electrical connections and use sealed junction boxes
• Engineer mounting structures to withstand high wind loads typical of coastal Mediterranean locations

Regular maintenance protocols should include monthly panel cleaning during dusty periods and quarterly inspection of electrical connections. Installing an automated monitoring system can help identify performance drops that indicate cleaning or maintenance needs. Despite these environmental challenges, El Kabaria's strong summer and spring solar potential makes it a viable location for solar PV installation when proper protective measures are implemented during system design and ongoing maintenance.

Solar output per kW of installed solar PV by season in El Kabaria

Seasonal solar PV output for Latitude: 36.7602, Longitude: 10.1998 (El Kabaria, 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 El Kabaria, Tunisia

To maximize your solar PV system's energy output in El Kabaria, Tunisia (Lat/Long 36.7602, 10.1998) 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 El Kabaria, 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 El Kabaria, 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	51° 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 El Kabaria, 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 El Kabaria, 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 El Kabaria, Tunisia

Topographical Features of El Kabaria Region

El Kabaria sits within the fertile Cap Bon Peninsula in northeastern Tunisia, characterized by gently rolling hills and relatively modest elevation changes. The landscape around this coastal region features a mixture of agricultural plains, low ridges, and gradual slopes that descend toward the Mediterranean Sea to the northeast. The terrain is predominantly composed of sedimentary formations with occasional limestone outcrops, creating a varied but generally accessible topography. The immediate vicinity of El Kabaria displays typical Mediterranean coastal plain characteristics, with elevations ranging from near sea level to approximately 200 meters above sea level within a 10-kilometer radius. Small valleys and depressions intersect the landscape, often following seasonal watercourses that drain toward the coast. These natural drainage patterns create a patchwork of slightly undulating terrain broken by flatter agricultural areas. Moving inland from El Kabaria, the topography becomes more pronounced with the presence of the Jebel Bou Kornine range to the southwest, though these mountains remain at a considerable distance from the immediate area. The local landscape maintains its generally gentle character, with slopes rarely exceeding 10-15 degrees in the immediate surroundings.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for extensive solar photovoltaic installations lie on the relatively flat to gently sloping agricultural plains that extend westward and southward from El Kabaria. These areas offer the dual advantages of minimal grading requirements and reduced construction costs while maintaining good accessibility via existing rural road networks. The flat expanses located approximately 5-8 kilometers southwest of El Kabaria present particularly favorable conditions for large-scale solar development. These areas feature stable soil conditions, minimal vegetation coverage outside of seasonal agricultural use, and gentle southward-facing slopes that would naturally optimize solar panel positioning without requiring extensive site preparation. Areas with slight southern exposure on the rolling hills between El Kabaria and the interior agricultural zones would also prove suitable for solar installations. The natural topography in these locations provides optimal panel orientation while the elevated positions offer good drainage and reduced risk of flooding during Tunisia's occasional heavy rainfall periods. The coastal plains extending northwest toward Nabeul present another promising zone for solar development, though developers would need to consider the proximity to existing agricultural operations and urban development. These flatter areas benefit from stable weather patterns and reduced wind exposure compared to more elevated locations. Less suitable areas include the steeper slopes found in the scattered hill country and any locations within active agricultural zones or near residential developments. The small valleys and depression areas, while flat, may present drainage challenges during the rainy season and could require additional site preparation to ensure proper water management around solar installations.
