Melilla, Spain is a reasonably good location for year-round solar energy generation, though it experiences significant seasonal variation in output. Located in the Northern Temperate Zone at coordinates 35.2852, -2.9495, this Spanish autonomous city on the North African coast benefits from a Mediterranean climate that provides decent solar conditions throughout the year.

Seasonal Solar Performance

The solar energy output varies considerably across the seasons. Summer delivers the strongest performance at 7.14 kWh per day per kW of installed solar capacity, making it the ideal time for solar generation. Spring follows as the second-best season with 5.85 kWh per day per kW, while autumn drops to 4.53 kWh per day per kW. Winter shows the lowest output at 3.30 kWh per day per kW, representing less than half of summer production. For optimal year-round energy capture, solar panels should be installed at a fixed tilt angle of 31 degrees facing south. This angle maximizes total annual production by accounting for the sun's varying position throughout the year and the daily solar irradiance patterns specific to this latitude.

Environmental and Weather Challenges

Several local factors in Melilla can impact solar panel performance and require consideration during installation:

• Saharan dust storms - The proximity to North Africa means panels can accumulate sand and dust, significantly reducing efficiency
• Salt air corrosion - Being a coastal location, salt-laden air can corrode panel frames and mounting hardware over time
• High summer temperatures - Extreme heat can reduce panel efficiency and stress electrical components
• Mediterranean weather patterns - Occasional heavy rains and strong winds require robust mounting systems

Preventative Installation Measures

To maximize energy production despite these challenges, several preventative measures should be implemented. Installing panels with easy access for regular cleaning helps combat dust accumulation, while using marine-grade aluminum frames and stainless steel hardware prevents salt corrosion. Ensuring adequate ventilation behind panels helps manage heat buildup during hot summers, and selecting panels with good high-temperature performance coefficients maintains efficiency. Robust mounting systems designed for wind loads protect against Mediterranean storms, while applying protective coatings to metal components extends system lifespan in the coastal environment. Regular maintenance schedules should include frequent cleaning during dusty periods and periodic inspection of all hardware for signs of corrosion or wear.

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 Melilla

Seasonal solar PV output for Latitude: 35.2852, Longitude: -2.9495 (Melilla, 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 Melilla, Spain

To maximize your solar PV system's energy output in Melilla, Spain (Lat/Long 35.2852, -2.9495) 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 Melilla, 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 Melilla, 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
19° South in Summer	40° South in Autumn	50° 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 Melilla, Spain

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 Melilla, Spain.

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 Melilla, Spain

Topographical Features of Melilla

Melilla sits on the Mediterranean coast of North Africa, positioned on a small peninsula that juts into the sea from the Moroccan mainland. The city occupies a relatively compact area characterized by steep coastal cliffs and rocky terrain that rises sharply from the waterline. The immediate landscape features dramatic elevation changes, with the historic old town perched on high bluffs overlooking the Mediterranean, while newer districts spread across the more gently sloping inland areas. The surrounding region exhibits typical Mediterranean coastal topography, with rolling hills and plateaus extending inland from the sea. These elevated areas are interspersed with valleys and wadis that channel seasonal rainfall toward the coast. The terrain becomes increasingly mountainous as one moves further inland into the Rif Mountains of Morocco, creating a backdrop of peaks and ridges that influence local weather patterns and provide natural boundaries. The coastal plain around Melilla is relatively narrow, constrained by the rising terrain to the south and west. This creates a compressed landscape where urban development must navigate between the sea and the ascending hills. The rocky substrate consists primarily of sedimentary formations typical of the North African Mediterranean coast, with limestone and sandstone predominating in many areas.

Optimal Areas for Large-Scale Solar Development

The most promising locations for extensive solar photovoltaic installations lie on the elevated plateaus and gentle slopes that extend inland from Melilla's immediate coastal zone. These areas benefit from relatively flat or moderately sloping terrain that minimizes grading requirements and construction costs while maximizing panel efficiency through optimal positioning. The rolling hills approximately five to fifteen kilometers inland from the coast present particularly attractive opportunities for solar development. These locations offer sufficient flat or gently undulating land for large arrays while remaining accessible for construction and maintenance activities. The elevated position of these sites also helps minimize the impact of coastal humidity and salt spray that can affect equipment performance and longevity. Areas to the southwest and south of Melilla, where the terrain transitions from coastal hills to broader inland plateaus, would be especially well-suited for major solar installations. These zones typically feature good drainage, stable geology, and adequate space for the infrastructure required to support utility-scale projects. The natural topography in these areas often provides gentle south-facing slopes that can enhance solar collection efficiency. The region's geological stability, combined with its position above the immediate coastal influence zone, makes these inland elevated areas ideal for long-term solar infrastructure investments. Access to existing road networks and proximity to electrical transmission infrastructure further enhance the viability of these locations for large-scale renewable energy development.
