Solar PV Analysis of Ferrol, Spain
Ferrol, Galicia, Spain, situated at latitude 43.504 and longitude -8.2315, presents a mixed picture for solar energy generation throughout the year. This coastal city in the Northern Temperate Zone experiences significant seasonal variations in solar output, which impact its overall suitability for photovoltaic (PV) installations.
Seasonal Solar Performance
Solar energy production in Ferrol peaks during the summer months, with an impressive daily output of 6.38 kWh per kW of installed capacity. Spring follows closely behind, generating 5.61 kWh/day. However, autumn sees a considerable drop to 3.48 kWh/day, while winter performance plummets to a mere 1.92 kWh/day.
This stark contrast between seasons suggests that Ferrol is most ideal for solar energy generation from late spring through early autumn. During these months, longer daylight hours and more direct sunlight contribute to higher energy yields, making it an excellent time for solar power production.
Optimal Panel Installation
To maximize year-round solar energy production in Ferrol, Galicia, fixed solar panels should be tilted at a 38-degree angle facing south. This optimal angle takes into account the city's latitude and seasonal sun paths, ensuring the best possible exposure to sunlight throughout the year.
Environmental and Weather Considerations
Ferrol's coastal location brings some challenges for solar energy production. The city experiences significant rainfall, with an average of 1,008 mm (39.7 inches) annually. This high precipitation can lead to reduced sunlight exposure and potentially impact solar panel efficiency.
Additionally, Ferrol is prone to foggy conditions, especially during the summer months. This coastal fog, known locally as "brétema," can obstruct sunlight and decrease solar panel performance.
Mitigating Factors
To address these environmental challenges, several preventative measures can be taken:
- Install high-quality, water-resistant solar panels designed to perform well in wet conditions.
- Implement a regular cleaning schedule to remove salt deposits and other debris that may accumulate due to the coastal environment.
- Consider using micro-inverters or power optimizers to minimize the impact of partial shading caused by fog or cloud cover.
While Ferrol may not be the most ideal location for year-round solar energy production, proper planning and installation techniques can help maximize energy output during the more favorable months and mitigate the effects of challenging weather conditions.
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 Ferrol
Seasonal solar PV output for Latitude: 43.504, Longitude: -8.2315 (Ferrol, 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 38° South in Ferrol, Spain
To maximize your solar PV system's energy output in Ferrol, Spain (Lat/Long 43.504, -8.2315) throughout the year, you should tilt your panels at an angle of 38° 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 Ferrol, 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 Ferrol, Spain. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 28° South in Summer | 48° South in Autumn | 58° South in Winter | 36° 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 Ferrol, 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 Ferrol, Spain.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Ferrol, Spain
The topography around Ferrol, Spain, is characterized by a diverse landscape that combines coastal features with inland hills and valleys. Ferrol is situated on the northern coast of Galicia, nestled in a deep natural harbor known as the Ría de Ferrol. The city itself is built on relatively flat terrain near the water's edge, but the surrounding areas quickly become more varied in elevation.
To the north and east of Ferrol, the coastline is rugged and dramatic, with steep cliffs and rocky shores interspersed with small beaches and coves. These coastal areas offer stunning views but are not particularly suitable for large-scale development due to their uneven terrain and environmental sensitivity.
Moving inland to the south and west, the landscape transitions into gently rolling hills and valleys. This area is characterized by a mix of farmland, forests, and small rural communities. The hills gradually increase in elevation as you move further from the coast, with some reaching heights of 200 to 400 meters above sea level. These inland areas are generally greener and more lush than the immediate coastal region, thanks to the area's mild and rainy climate.
When considering locations for large-scale solar PV installations near Ferrol, the most suitable areas would likely be found in the inland regions to the south and southeast of the city. These areas offer several advantages for solar energy development:
- Flatter terrain: The gently rolling hills provide more expansive, open spaces that can accommodate large solar arrays without requiring extensive land modification.
- Distance from the coast: Being further inland reduces exposure to salt spray and coastal weather patterns that could potentially damage solar equipment.
- Lower population density: The rural nature of these areas means there's likely to be less competition for land use and fewer concerns about visual impact on residential areas.
- Proximity to existing infrastructure: These regions are close enough to Ferrol and other towns to potentially connect to existing power grids without requiring extensive new transmission lines.
However, it's important to note that Galicia, including the Ferrol area, is known for its relatively high rainfall and frequent cloud cover. This climate characteristic may impact the overall efficiency and economic viability of large-scale solar projects in the region. Therefore, any potential solar development would require careful site selection and thorough feasibility studies to ensure optimal performance and return on investment.
