Montcada i Reixac, Spain, offers a promising location for solar PV energy generation, with distinct seasonal variations in electricity production throughout the year. This municipality in Catalonia experiences typical Mediterranean climate patterns that influence solar energy potential.

Seasonal Solar Production

Solar panels in Montcada i Reixac perform exceptionally well during summer months, generating an average of 7.14kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season, with 5.50kWh/day per installed kilowatt. Production decreases significantly in autumn (3.52kWh/day) and reaches its lowest point in winter (2.38kWh/day).

This seasonal pattern creates a more than threefold difference between peak summer and minimum winter production, which is typical for locations in the Northern Temperate Zone. The substantial spring production indicates that favorable conditions begin relatively early in the year.

Optimal Panel Installation

For fixed solar panel installations in Montcada i Reixac, the ideal tilt angle to maximize year-round energy production is 36 degrees facing South. This angle has been calculated by analyzing daily solar elevation patterns at this specific latitude, weighted according to the location's solar irradiance potential throughout the year.

Environmental Considerations

Several factors could potentially impact solar production in Montcada i Reixac:

• Dust and particulate matter from nearby industrial areas may accumulate on panels, reducing efficiency if not regularly cleaned
• Morning fog or coastal humidity can temporarily reduce production, particularly in autumn and winter months
• Occasional heatwaves in summer can slightly reduce panel efficiency when temperatures exceed optimal operating ranges

Preventative measures should include regular cleaning schedules, installing panels with sufficient elevation to avoid ground-level morning fog, and ensuring adequate airflow beneath panels to mitigate efficiency losses during high-temperature periods. Additionally, selecting panels with good temperature coefficients would be advantageous for this Mediterranean climate.

Overall, Montcada i Reixac presents favorable conditions for solar PV installation, with particularly strong production potential from late spring through early autumn. The relatively mild winter conditions still allow for meaningful energy generation year-round, making it a suitable location for solar energy investments.

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 Montcada I Reixac

Seasonal solar PV output for Latitude: 41.4814, Longitude: 2.191 (Montcada I Reixac, 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 36° South in Montcada I Reixac, Spain

To maximize your solar PV system's energy output in Montcada I Reixac, Spain (Lat/Long 41.4814, 2.191) throughout the year, you should tilt your panels at an angle of 36° 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 Montcada I Reixac, 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 Montcada I Reixac, Spain. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 36° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
25° South in Summer	45° South in Autumn	56° South in Winter	34° 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 Montcada I Reixac, 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 Montcada I Reixac, 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 Montcada I Reixac, Spain

The topography around Montcada i Reixac presents a diverse landscape characterized by a mixture of flat valley areas and surrounding hills. This municipality sits in the Besòs River valley in Catalonia, approximately 10 kilometers north of Barcelona. The terrain features a notable transition between the coastal plains and the pre-coastal mountain ranges.

Valley and Plains

Montcada i Reixac occupies a strategic position where the Besòs River creates a natural corridor. The central part of the municipality lies at relatively low elevation (around 30-50 meters above sea level) in this river valley, which provides flat to gently sloping terrain. This valley area is heavily urbanized and industrialized, with the river Besòs flowing through it.

Surrounding Highlands

The flat valley is bordered by more pronounced relief features. To the west rises the Collserola mountain range, which forms a natural boundary between Montcada i Reixac and Barcelona. This mountain range reaches heights of over 500 meters and consists of rounded peaks and forested slopes. To the east and northeast lie the lower foothills of the Serralada de Marina (Marina Mountain Range), which presents a more moderate relief with hills reaching approximately 200-300 meters. This area features a mix of Mediterranean forest and scrubland vegetation.

Potential Areas for Solar PV Development

For large-scale solar photovoltaic installations, several areas around Montcada i Reixac show promise based on topographical considerations: The flatter areas in the Besòs River valley offer the most immediate potential for solar development. These areas have minimal slope, reducing installation costs and maximizing exposure to sunlight. However, much of this land is already developed for urban and industrial purposes. The gentle slopes of the eastern foothills present good opportunities for solar PV development. South-facing slopes at moderate elevations (between 100-200 meters) would receive consistent solar radiation throughout the year. These areas often have less dense vegetation and development compared to the valley floor. Some of the plateau areas atop the lower hills of the Serralada de Marina could be suitable for solar installations, particularly where the terrain flattens out. These elevated positions benefit from reduced shadowing effects from surrounding terrain.

Topographical Challenges

The steeper slopes of the Collserola range to the west are less ideal for large-scale solar installations due to increased installation complexity, potential shadowing from adjacent ridges, and greater environmental sensitivity as these areas often contain protected natural spaces. The dense urban fabric within the valley creates limited availability of large continuous parcels necessary for utility-scale solar development. This constraint might direct solar development toward the periphery of the municipality or to brownfield sites within the industrial zones. Areas near the river may be subject to periodic flooding and should be evaluated carefully before development. The riparian zones along the Besòs River also often have environmental protections in place that would restrict development. In conclusion, the most promising areas for large-scale solar PV development around Montcada i Reixac would be the gentle south-facing slopes of the eastern foothills and any available flat industrial or post-industrial land in the valley that isn't subject to flooding or already committed to other uses. These areas combine favorable topography with proximity to existing electrical infrastructure, making them potentially viable candidates for solar energy production.
