Annaba, Algeria, situated at latitude 36.7859 and longitude 7.6282, offers a promising location for solar PV energy generation throughout the year. This coastal city in northeastern Algeria experiences varying levels of solar potential across different seasons.

Seasonal Solar Performance

Solar energy production in Annaba follows a predictable pattern, with peak performance during the summer months. The expected daily electricity output per kilowatt of installed solar capacity ranges from a high of 7.49 kWh in summer to a low of 3.23 kWh in winter. Spring and autumn serve as transitional periods, with spring showing particularly strong potential at 6.08 kWh per day. The autumn months see a moderate decline to 4.12 kWh daily. This seasonal variation is typical for locations in the Northern Temperate Zone, where daylight hours and sun angle change significantly throughout the year.

Optimal Panel Installation

To maximize year-round solar energy production in Annaba, fixed solar panels should be tilted at an angle of 32 degrees facing south. This optimal angle has been calculated to capture the most sunlight across all seasons, taking into account the city's latitude and the Earth's elliptical orbit.

Prime Generation Periods

The most ideal times for solar energy generation in Annaba are during the summer months, typically from June to August. During this period, longer daylight hours and higher sun angles contribute to peak performance. Spring follows as the second-most productive season, making the period from March to August particularly favorable for solar energy harvesting.

Environmental Considerations

While Annaba's climate is generally conducive to solar energy production, there are some environmental factors to consider: 1. Coastal humidity: Annaba's proximity to the Mediterranean Sea can lead to increased humidity, potentially causing slight reductions in panel efficiency. 2. Occasional dust storms: The region may experience dust storms, particularly during the summer months, which can temporarily reduce panel performance. To mitigate these factors, regular cleaning and maintenance of solar panels is crucial. Installing panels at the recommended 32-degree tilt can also help with natural cleaning during rainfall. Additionally, using high-quality, dust-resistant panels and implementing automated cleaning systems can further enhance energy production and system longevity. Overall, Annaba's location offers a favorable environment for solar PV energy generation, with ample sunlight throughout the year and manageable environmental challenges.

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 52 locations across Algeria. 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 Annaba

Seasonal solar PV output for Latitude: 36.7859, Longitude: 7.6282 (Annaba, Algeria), 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 Annaba, Algeria

To maximize your solar PV system's energy output in Annaba, Algeria (Lat/Long 36.7859, 7.6282) 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 Annaba, Algeria

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 Annaba, Algeria. 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 Annaba, Algeria

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 Annaba, Algeria.

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 Annaba, Algeria

The topography around Annaba, Algeria is diverse and interesting. The city itself is located on the northeastern coast of Algeria, nestled between the Mediterranean Sea and a series of hills and mountains. To the west and southwest of Annaba, the terrain gradually rises into the foothills of the Tell Atlas mountain range. These hills become more pronounced as you move further inland, creating a picturesque backdrop for the coastal city.

To the east of Annaba, the landscape is dominated by coastal plains and wetlands, including Lake Fetzara, a large shallow lake that provides important habitat for various bird species. The coastline near Annaba features beautiful beaches and rocky coves, with some small islands visible offshore.

Moving south from Annaba, the terrain becomes increasingly hilly and eventually transitions into the more rugged landscape of the Tell Atlas mountains. This region is characterized by steep slopes, deep valleys, and forested areas, particularly as you approach the Edough Peninsula to the northwest of the city.

Areas Suitable for Large-Scale Solar PV

For large-scale solar photovoltaic (PV) installations, the most suitable areas near Annaba would likely be found to the south and southwest of the city. These regions offer several advantages for solar energy development:

1. The inland areas south of Annaba have more consistent sunshine and less coastal influence, which can reduce cloud cover and fog that might impact solar energy production.

2. The gently rolling hills and plateaus found in this direction provide ample flat or slightly sloped land that is ideal for installing large solar arrays.

3. These areas are generally less densely populated than the coastal regions, potentially offering more available land for development with fewer conflicts over land use.

4. The proximity to existing infrastructure in Annaba could make it easier to connect new solar installations to the power grid.

However, it's important to note that specific site selection would require detailed environmental and technical assessments. Factors such as local climate data, soil conditions, and proximity to transmission lines would all need to be carefully considered before determining the most suitable locations for large-scale solar PV projects in the region.
