Ferryville, Bizerte Governorate, Tunisia, located in the Northern Temperate Zone, has a generally favorable location for solar PV energy generation, but with significant seasonal variations.
Here's a breakdown of the solar energy production potential throughout the year:
1. Summer: Excellent production (7.35 kWh/day per kW installed)
2. Spring: Very good production (6.04 kWh/day per kW installed)
3. Autumn: Moderate production (3.93 kWh/day per kW installed)
4. Winter: Low production (2.85 kWh/day per kW installed)
The best times for solar energy generation at this location are clearly during the summer months, followed by spring. During these seasons, the longer days and higher sun angles result in significantly more solar energy production. Autumn and winter see a notable decrease in production due to shorter days and lower sun angles.
For fixed panel installations at this location, the ideal angle to tilt panels for maximizing year-round production is 32 degrees facing South. This angle helps optimize energy capture across all seasons, balancing the higher summer sun with the lower winter sun.
Regarding environmental or weather factors that could impede solar production:
1. Dust and sand: Given Tunisia's proximity to the Sahara Desert, dust and sand accumulation on solar panels could be a significant issue. This can reduce panel efficiency by blocking sunlight.
Preventative measure: Regular cleaning of panels and possibly installing automated cleaning systems.
2. High temperatures: While sunlight is abundant, extremely high temperatures can actually reduce solar panel efficiency.
Preventative measure: Ensure proper ventilation behind panels and consider using high-efficiency panels designed to perform better in hot conditions.
3. Occasional sandstorms: These could temporarily reduce solar output and potentially damage equipment if severe.
Preventative measure: Install protective covers or systems that can shield panels during extreme weather events.
4. Coastal location: Being near the Mediterranean Sea, salt air corrosion could be a concern for solar equipment.
Preventative measure: Use corrosion-resistant materials and apply protective coatings to vulnerable components.
While these factors exist, they are not insurmountable obstacles. With proper planning and maintenance, Ferryville can still be a very good location for solar PV energy generation, especially during the summer and spring months.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 53 locations across Tunisia. 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 Ferryville
Seasonal solar PV output for Latitude: 37.1554, Longitude: 9.7861 (Ferryville, 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 Ferryville, Tunisia
To maximize your solar PV system's energy output in Ferryville, Tunisia (Lat/Long 37.1554, 9.7861) 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 Ferryville, 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 Ferryville, 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 | 30° 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 Ferryville, 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 Ferryville, 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 Ferryville, Tunisia
Ferryville, Tunisia (now known as Menzel Bourguiba) is located in northern Tunisia, near the Mediterranean coast. The topography of the area around Ferryville is characterized by the following features:
1. Coastal plains: The immediate area around Ferryville is relatively flat, as it is part of the coastal plain that runs along the northern Tunisian coast.
2. Lake Ichkeul: To the west of Ferryville is Lake Ichkeul, a large freshwater lake that is an important ecological site and UNESCO World Heritage site.
3. Hills and low mountains: Moving inland from the coast, the terrain becomes more hilly, with some low mountain ranges in the vicinity.
4. Agricultural land: The surrounding area includes significant agricultural land, particularly in the flatter regions.
For large-scale solar PV installations, the most suitable areas nearby would likely be:
1. Inland plains: Areas south and southeast of Ferryville, where the terrain is flatter and there is less competition for land use with agriculture or urban development.
2. Elevated plateaus: Some of the higher, flatter areas in the nearby hills could be suitable, as they may receive more consistent sunlight and have fewer obstructions.
3. Former agricultural land: Any degraded or less productive agricultural land in the region could be repurposed for solar installations.
When considering locations for large-scale solar PV, it's important to take into account factors such as:
- Proximity to existing power infrastructure
- Accessibility for construction and maintenance
- Minimal impact on sensitive ecological areas (like Lake Ichkeul)
- Avoidance of prime agricultural land
- Local climate conditions, including dust and wind patterns
It's worth noting that while the area around Ferryville has good solar potential, the best locations for large-scale solar PV in Tunisia are generally found further south, in the more arid and less populated regions of the country. However, the northern location of Ferryville could be advantageous in terms of proximity to population centers and existing infrastructure.
