Bizerte, Tunisia, situated at 37.2774° N, 9.8749° E, offers a promising location for solar PV energy generation throughout the year. Located in the Northern Temperate Zone, this coastal city experiences varying levels of solar potential across different seasons.

Seasonal Solar Performance

Solar energy production in Bizerte peaks during the summer months, with an impressive output of 7.35 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 6.04 kWh/day. Autumn sees a moderate decrease to 3.93 kWh/day, while winter experiences the lowest output at 2.85 kWh/day.

The substantial difference between summer and winter production highlights the seasonal variability at this latitude. However, the relatively high spring and autumn outputs indicate that Bizerte maintains good solar potential for much of the year.

Optimal Panel Installation

To maximize year-round solar energy production in Bizerte, fixed solar panels should be tilted at a 32-degree angle facing south. This optimal tilt angle takes into account the city's latitude and seasonal sun paths, ensuring the best overall performance throughout the year.

Environmental Considerations

While Bizerte's location is generally favorable for solar energy production, there are a few environmental factors to consider:

1. Coastal humidity and salt spray: Being a coastal city, Bizerte may experience higher humidity levels and salt spray from the Mediterranean Sea. These factors can potentially accelerate corrosion of solar panel components.
2. Dust and sand: The proximity to the Sahara Desert might lead to occasional dust storms, which can reduce panel efficiency.

To mitigate these issues, installers should use corrosion-resistant materials and apply protective coatings to solar panels and mounting systems. Regular cleaning and maintenance schedules should be implemented to remove salt and dust buildup, ensuring optimal performance.

Despite these minor challenges, Bizerte's location remains highly suitable for solar PV energy generation. With proper installation techniques and maintenance practices, the city can harness significant solar energy throughout the year, particularly from spring through autumn.

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.

Ideally tilt fixed solar panels 32° South in Bizerte, Tunisia

To maximize your solar PV system's energy output in Bizerte, Tunisia (Lat/Long 37.2774, 9.8749) 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.

At Latitude: 37.2774, Longitude: 9.8749, the ideal angle to tilt panels is 32° South

Seasonally adjusted solar panel tilt angles for Bizerte, 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 Bizerte, Tunisia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° South tilt angle throughout the year.

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 Bizerte, 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 Bizerte, 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 Bizerte, Tunisia

The topography around Bizerte, Tunisia is quite varied and interesting. Bizerte is a coastal city located in northern Tunisia, situated on the Mediterranean Sea. The immediate area around the city is characterized by a mix of low-lying coastal plains and gently rolling hills.

To the east and southeast of Bizerte, you'll find a relatively flat coastal plain that extends for several kilometers inland. This area is dotted with small lakes and lagoons, the most prominent being Lake Bizerte, which is connected to the Mediterranean Sea by a narrow channel. The land here is generally low-lying and fertile, making it suitable for agriculture.

As you move further inland to the south and southwest, the terrain becomes more undulating, with a series of low hills and shallow valleys. These hills rarely exceed 200 meters in height but provide a noticeable contrast to the coastal plain. The landscape in this area is often characterized by a patchwork of agricultural fields, olive groves, and scattered patches of natural vegetation.

To the west of Bizerte, the terrain becomes more rugged as it transitions into the foothills of the Tell Atlas mountain range. While not particularly high in this region, these hills provide a more dramatic backdrop to the coastal areas and can reach heights of up to 500 meters in some places.

Regarding areas suitable for large-scale solar PV (photovoltaic) installations, the most promising locations would likely be found in the inland areas to the south and southwest of Bizerte. These regions offer several advantages for solar energy production:

1. They have more consistent exposure to sunlight throughout the day, as they are less affected by coastal weather patterns.
2. The gently rolling terrain provides ample flat or slightly sloped areas that are ideal for installing solar panels.
3. These inland areas are generally less densely populated, which means there's more available land for large-scale installations.
4. The agricultural nature of much of this land means that it's already cleared and easily accessible, reducing the cost and environmental impact of site preparation.

However, it's important to note that any large-scale solar PV project would require detailed site-specific assessments, including factors such as local climate data, grid connectivity, and environmental impact studies. Additionally, care should be taken to balance the needs of solar energy production with the preservation of agricultural land and natural habitats in the region.
