Mostaganem, Algeria, situated at coordinates 35.9125, 0.1031 in the Northern Temperate Zone, offers varying potential for solar PV energy generation throughout the year. This coastal location experiences significant seasonal fluctuations in solar energy production that are worth understanding for anyone considering solar installation.

Seasonal Solar Production

Solar energy generation at Mostaganem follows a predictable seasonal pattern. Summer stands out as the most productive season, with panels generating approximately 7.66kWh per day for each kilowatt installed. Spring follows as the second most productive season, yielding about 6.37kWh daily per kilowatt. Production decreases considerably during autumn (4.47kWh/day) and reaches its lowest point in winter (3.36kWh/day).

This seasonal variation means that a solar installation will produce more than twice the electricity in summer compared to winter months. The substantial spring and summer production makes this an attractive location for solar energy, though winter outputs remain moderate enough to provide useful energy year-round.

Optimal Panel Installation

For fixed solar panel installations in Mostaganem, the ideal tilt angle to maximize year-round energy production is 31 degrees facing South. This specific angle has been calculated to optimize the annual solar harvest by accounting for the location's latitude and the Earth's elliptical orbit around the sun.

Environmental Considerations

Several environmental factors could potentially affect solar production at this Algerian coastal location:

• Dust and sand accumulation: Mostaganem's proximity to arid regions means panels can become covered with fine dust and sand, reducing efficiency by up to 15-25% if not regularly cleaned.
• Coastal salt spray: Being near the Mediterranean Sea, salt deposits can gradually build up on panel surfaces, potentially causing both reduced light transmission and accelerated corrosion.
• High summer temperatures: While Mostaganem benefits from excellent summer sun, high temperatures can slightly reduce panel efficiency, as photovoltaic cells typically lose efficiency above 25°C.

Preventative Measures

To maximize solar energy production in this location, several preventative measures are recommended:

• Implement regular cleaning protocols, ideally monthly during dry seasons, using appropriate non-abrasive methods to remove dust and salt deposits
• Install panels with adequate ventilation behind them to reduce temperature-related efficiency losses
• Consider marine-grade components and protective coatings for all metal parts to prevent salt corrosion
• Use tempered, anti-reflective glass panels that are more resistant to environmental stressors
• Install monitoring systems to quickly identify any unexpected drops in performance

With these considerations addressed, Mostaganem offers a generally favorable location for solar PV installations, with particularly strong production potential from March through October.

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 Mostaganem

Seasonal solar PV output for Latitude: 35.9125, Longitude: 0.1031 (Mostaganem, 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 31° South in Mostaganem, Algeria

To maximize your solar PV system's energy output in Mostaganem, Algeria (Lat/Long 35.9125, 0.1031) throughout the year, you should tilt your panels at an angle of 31° 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 Mostaganem, 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 Mostaganem, Algeria. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 31° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
20° South in Summer	40° South in Autumn	51° South in Winter	28° 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 Mostaganem, 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 Mostaganem, 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 Mostaganem, Algeria

Mostaganem is situated along the northwestern coast of Algeria, facing the Mediterranean Sea. The city itself is perched on a plateau that gently rises from the coastline, creating a natural viewpoint over the azure waters. This coastal region features a varied topography characterized by a narrow coastal plain that quickly transitions into rolling hills and plateaus as one moves inland.

Coastal Features

The immediate coastline around Mostaganem presents sandy beaches interspersed with rocky sections. This coastal strip is relatively flat, with elevations typically less than 50 meters above sea level. The shore is punctuated by small coves and bays, creating a somewhat irregular coastline that has historically served the city well as a port.

Inland Terrain

Moving inland from Mostaganem, the landscape gradually rises into a series of plateaus and hills. These elevations generally range between 100 and 300 meters above sea level, creating a stepped appearance to the terrain. The plateaus are characterized by relatively flat expanses that are occasionally cut by seasonal wadis (dry riverbeds) that channel water during the rainy season. Further inland, the terrain becomes more undulating with a mix of hills and small valleys. The soil composition transitions from coastal sandy areas to more clay and limestone-based soils that support different vegetation patterns, primarily scrubland and agricultural plots where irrigation is available.

Agricultural Plains

To the south and southeast of Mostaganem lies the fertile Chelif Plain, one of Algeria's most productive agricultural regions. This plain represents a significant topographical feature in the region, with its relatively flat terrain and rich alluvial soils. The plain is bordered by more mountainous terrain as one moves further south toward the Tell Atlas mountain range.

Solar PV Suitability

When considering areas near Mostaganem for large-scale solar photovoltaic installations, several regions stand out as particularly suitable based on topographical considerations: The inland plateaus to the south and southeast of Mostaganem offer ideal conditions for solar PV deployment. These areas combine several advantageous features: relatively flat terrain that minimizes construction challenges and costs; elevated positions that typically experience less coastal fog; and sparse vegetation that reduces the environmental impact of clearing land. Specifically, the northern edges of the Chelif Plain present excellent opportunities. These locations maintain good access to existing infrastructure while providing the expansive, uninterrupted spaces needed for large-scale installations. The gentle slopes in this region also facilitate natural drainage, reducing the risk of flooding that could damage equipment. Areas approximately 15-20 kilometers inland also benefit from reduced maritime influence, which can sometimes bring humidity and morning fog to the immediate coastal areas. These inland zones typically experience clearer atmospheric conditions, maximizing solar exposure. The terrain southwest of Mostaganem, heading toward Oran, also contains several plateau regions that combine favorable topography with proximity to existing power infrastructure, making them logistically attractive for solar development. Less suitable areas include the immediate coastal zone, which has higher value for tourism and urban development, as well as the more rugged hilly terrain where installation would be more complex and costly due to the varied elevation and potential shadowing effects.
