La Mornaghia, Manouba, Tunisia presents a moderately favorable location for year-round solar PV energy generation, though with significant seasonal variations that potential solar installers should carefully consider.
Seasonal Energy Production Patterns
The location experiences substantial fluctuations in solar energy output throughout the year. Summer delivers the highest production at 7.34kWh per day per kW of installed capacity, making it the peak season for solar generation. Spring follows as the second-best performing season with 5.98kWh daily output per kW. Autumn sees a notable decline to 4.02kWh per day per kW, while winter represents the challenging period with only 3.01kWh daily per kW. This winter figure is less than half of the summer production, indicating that energy storage or grid-tied systems become particularly important during the colder months.Optimal Installation Configuration
For maximum year-round energy production at La Mornaghia, Manouba, 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 the location's specific latitude.Environmental and Weather Considerations
Several local factors in Tunisia could potentially impact solar panel performance and require preventative measures:- Dust and Sand Accumulation: Tunisia's proximity to the Sahara Desert means regular dust storms and sand particles can coat solar panels, significantly reducing their efficiency
- High Summer Temperatures: Extreme heat can reduce panel efficiency and accelerate equipment degradation
- Occasional Heavy Rainfall: While generally dry, Tunisia can experience intense rainfall that may cause drainage issues
- Salt Air Corrosion: Being near the Mediterranean coast, salt-laden air can corrode metal components over time
Recommended Preventative Measures
To maximize energy production despite these challenges, several installation strategies prove effective:- Regular Cleaning Systems: Install automated cleaning systems or schedule frequent manual cleaning to remove dust and sand buildup
- Enhanced Ventilation: Ensure adequate airflow around panels to prevent overheating during hot summer months
- Corrosion-Resistant Materials: Use marine-grade aluminum frames and stainless steel mounting hardware to withstand salt air exposure
- Proper Drainage: Design mounting systems with adequate drainage to prevent water pooling during heavy rains
- Quality Inverters: Install inverters in shaded, well-ventilated locations to protect them from extreme temperatures
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in La Mornaghia
Seasonal solar PV output for Latitude: 36.7575, Longitude: 10.021 (La Mornaghia, 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 La Mornaghia, Tunisia
To maximize your solar PV system's energy output in La Mornaghia, Tunisia (Lat/Long 36.7575, 10.021) 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 La Mornaghia, 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 La Mornaghia, 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 La Mornaghia, 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 La Mornaghia, Tunisia.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 La Mornaghia, Tunisia
Topographical Features of La Mornaghia Region
La Mornaghia sits within the gently undulating landscape of northeastern Tunisia, positioned in the fertile coastal plains that characterize much of the country's Mediterranean shoreline. The terrain around this location consists primarily of low-lying agricultural land with modest elevation changes, creating a relatively flat to gently rolling topography that extends inland from the nearby coast. The immediate area features predominantly sedimentary soils formed over millennia by ancient marine deposits and alluvial processes. These plains are punctuated by occasional low hills and ridges that rarely exceed modest heights, creating a landscape that transitions gradually between different elevation zones. The topography becomes slightly more varied as one moves further inland toward the south and southwest, where the terrain begins to show more pronounced undulations. Drainage patterns in the region are characterized by seasonal watercourses and agricultural channels that flow generally northeastward toward the Mediterranean Sea. The land shows evidence of extensive human modification through centuries of agricultural use, with field boundaries and irrigation systems creating a patchwork pattern across the landscape.Climate and Environmental Conditions
The region experiences a Mediterranean climate with hot, dry summers and mild, relatively wet winters. This climate pattern creates favorable conditions for solar energy generation, particularly during the extended dry season when cloud cover remains minimal for months at a time. The coastal influence moderates temperature extremes while maintaining consistently clear skies during peak solar seasons. Wind patterns in the area are influenced by both Mediterranean sea breezes and regional atmospheric circulation. These winds can affect solar panel efficiency through cooling effects but may also contribute to dust accumulation on panel surfaces, particularly during dry periods when agricultural activities and natural processes generate airborne particles.Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations around La Mornaghia would be the flatter agricultural plains extending to the south and southwest of the immediate area. These zones offer several advantages including minimal topographical obstacles, reduced grading requirements, and lower development costs compared to more varied terrain. Areas with gentle southern-facing slopes would be particularly favorable, as they naturally optimize panel orientation while maintaining manageable construction conditions. The relatively stable soil conditions throughout much of the region provide good foundation support for large solar arrays, though site-specific geotechnical analysis would be necessary for any major installation. The coastal plains to the northeast, while topographically suitable, may face competing land use pressures from agriculture and urban development. Moving inland toward areas with lower agricultural productivity would likely encounter less resistance while maintaining excellent solar exposure characteristics. Locations with existing infrastructure access, including roads and electrical transmission capabilities, would offer additional advantages for large-scale solar development. The region's proximity to major population centers and industrial areas provides ready markets for solar-generated electricity, making otherwise marginal agricultural land potentially more valuable for energy production purposes.Citation Guide
