Algeciras, Andalusia, Spain presents a moderately favorable location for year-round solar PV energy generation, though with significant seasonal variations in output. Located in the Northern Temperate Zone at coordinates 36.1413, -5.4454, this coastal city experiences the typical Mediterranean solar patterns that make it reasonably suitable for solar installations.

Seasonal Solar Performance

The solar energy production at Algeciras varies considerably throughout the year. Summer delivers the highest output at 8.28kWh per day per kW of installed solar capacity, making it the prime season for solar generation. Spring follows as the second-best period with 6.32kWh per day per kW, offering strong production as daylight hours increase and sun angles improve. Autumn sees a notable decline to 4.65kWh per day per kW as the sun's position lowers and weather patterns shift. Winter presents the most challenging period with only 2.92kWh per day per kW, representing about 35% of summer production levels. This dramatic seasonal swing means solar installations must be sized appropriately to account for winter's reduced output.

Optimal Panel Configuration

For fixed panel installations at Algeciras, Andalusia, the ideal tilt angle is 31 degrees facing south to maximize total year-round solar production. This angle represents the optimal compromise across all seasons, calculated by weighing daily solar elevation angles against actual solar irradiance data throughout the year.

Local Factors Affecting Solar Production

Several environmental and weather factors in Algeciras can impact solar PV performance:

• Salt air corrosion from the nearby Mediterranean Sea and Atlantic Ocean proximity
• Dust and sand accumulation from North African weather patterns
• High humidity levels that can affect electrical components
• Occasional strong winds from the Strait of Gibraltar

The coastal location exposes solar installations to salt-laden air that can corrode mounting hardware and electrical connections over time. Additionally, Algeciras occasionally experiences dust storms carrying fine particles from North Africa, which can significantly reduce panel efficiency by blocking sunlight.

Preventative Installation Measures

To maximize energy production despite these challenges, several protective measures should be implemented:

• Use marine-grade aluminum or stainless steel mounting systems with anti-corrosion coatings
• Install panels with easy access for regular cleaning to remove salt and dust buildup
• Apply protective sealants to all electrical connections and use weatherproof junction boxes
• Consider automated cleaning systems for larger installations
• Ensure robust mounting to withstand coastal wind loads

Regular maintenance becomes particularly important in this coastal environment. Monthly cleaning of panels and quarterly inspection of electrical connections can prevent significant production losses. The investment in corrosion-resistant materials and proper sealing typically pays for itself through improved long-term performance and reduced maintenance costs. Despite these challenges, Algeciras remains a viable location for solar PV installations, particularly when proper preventative measures are implemented during the design and installation phases.

Solar output per kW of installed solar PV by season in Algeciras

Seasonal solar PV output for Latitude: 36.1413, Longitude: -5.4454 (Algeciras, Spain), 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 Algeciras, Spain

To maximize your solar PV system's energy output in Algeciras, Spain (Lat/Long 36.1413, -5.4454) 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 Algeciras, Spain

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 Algeciras, Spain. 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	41° 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.

   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 Algeciras, Spain

Topographical Features Around Algeciras

Algeciras sits at the southern tip of Spain in Andalusia, positioned strategically at the northern entrance to the Strait of Gibraltar. The city occupies a relatively flat coastal plain that extends inland from the Bay of Gibraltar, with the terrain gradually rising toward the interior. This coastal location places Algeciras at sea level, providing an excellent foundation for development and infrastructure. The immediate surroundings feature gently rolling hills that climb steadily as they move away from the Mediterranean coastline. To the north and northwest, the landscape becomes increasingly mountainous, with the Sierra de Algodonales and other ranges of the Cordillera Bética system dominating the horizon. These mountains create a natural amphitheater effect around the coastal plain, offering protection from northern weather systems while allowing southern exposure to prevail. The Rock of Gibraltar rises dramatically just across the bay to the southeast, while the Moroccan coast of Africa lies clearly visible across the narrow strait to the south. This unique geographical position creates a distinctive microclimate influenced by both Mediterranean and Atlantic weather patterns.

Terrain Characteristics for Solar Development

The coastal plain extending north and northeast from Algeciras presents the most favorable topography for large-scale solar photovoltaic installations. These areas feature relatively flat to gently undulating terrain with gradual slopes that rarely exceed ten degrees. The soil composition consists primarily of sedimentary deposits and alluvial plains, making ground preparation and foundation work straightforward for solar infrastructure. Moving inland toward the municipalities of Los Barrios and Castellar de la Frontera, the terrain remains manageable for solar development while offering increased elevation. These slightly elevated positions provide excellent exposure to solar radiation while maintaining accessibility for construction equipment and maintenance vehicles. The rolling hills in these areas typically feature south-facing slopes that naturally optimize panel orientation.

Most Suitable Areas for Large-Scale Solar Projects

The agricultural plains stretching northeast toward Jerez de la Frontera represent prime territory for utility-scale solar installations. This region combines flat topography with minimal existing development, reducing land acquisition complications. The area benefits from excellent road networks connecting to major transmission infrastructure, facilitating both construction logistics and grid interconnection. The elevated plateaus near Tarifa, approximately thirty kilometers west of Algeciras, offer another excellent option for solar development. While this region experiences strong winds that require careful engineering considerations, the consistent elevation and open terrain provide optimal conditions for photovoltaic arrays. The existing renewable energy infrastructure in this area, developed primarily for wind power, creates synergies for solar projects. The inland valleys between the coastal range and the higher mountains present additional opportunities, particularly around the municipalities of Jimena de la Frontera and Castellar de la Frontera. These locations offer protection from coastal weather while maintaining the gentle topography essential for cost-effective solar construction. The agricultural character of much of this land means fewer obstacles to large-scale development compared to more densely populated coastal areas.
