Capellades, Catalonia, Spain, located in the Northern Temperate Zone at coordinates 41.528°N, 1.6842°E, offers a reasonably good location for year-round solar photovoltaic energy generation, though with significant seasonal variation typical of Mediterranean climates.
Seasonal Solar Performance
The solar energy output at this location shows strong seasonal patterns. Summer delivers the highest production at 7.31 kWh per day per kW of installed solar capacity, making it the peak season for solar generation. Spring follows as the second-best season with 5.77 kWh per day per kW, offering excellent conditions for solar energy production. Autumn performance drops to 3.69 kWh per day per kW, which is still reasonable for maintaining energy generation during the transitional season. Winter presents the most challenging conditions with only 2.37 kWh per day per kW, representing about one-third of summer production levels.Optimal Installation Configuration
For maximum year-round solar energy production at Capellades, Catalonia, fixed solar panels should be tilted at 36 degrees facing south. This angle has been calculated to optimize total annual energy output by accounting for the sun's changing position throughout the year and weighting the angles based on actual solar irradiance data.Local Environmental Factors
Several environmental and weather factors in the Capellades region could potentially impact solar panel performance:- Mediterranean dust and particulate matter that can accumulate on panel surfaces
- Occasional intense rainfall and storms that may cause temporary shading or debris accumulation
- Regional air pollution from nearby industrial areas that can reduce solar irradiance
- Seasonal pollen deposits, particularly during spring months
Preventative Measures
To maximize solar energy production despite these challenges, several installation strategies can be implemented. Regular cleaning schedules should be established, particularly during dusty periods and after storms, to maintain optimal panel efficiency. Installing panels with adequate spacing and proper drainage helps prevent debris accumulation and allows for easier maintenance access. Choosing high-quality mounting systems that can withstand regional weather patterns ensures long-term stability and performance. Consider installing monitoring systems that can detect performance drops, allowing for prompt maintenance when environmental factors impact energy generation. Additionally, selecting solar panels with anti-reflective coatings and self-cleaning properties can help minimize the impact of dust and pollen accumulation.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 Capellades
Seasonal solar PV output for Latitude: 41.528, Longitude: 1.6842 (Capellades, 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 Capellades, Spain
To maximize your solar PV system's energy output in Capellades, Spain (Lat/Long 41.528, 1.6842) 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 Capellades, 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 Capellades, 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 | 46° South in Autumn | 57° 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 Capellades, 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 Capellades, 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 Capellades, Spain
Topographical Features of Capellades
Capellades sits in the Anoia comarca of Catalonia, positioned within the Pre-Pyrenean foothills at an elevation of approximately 280 meters above sea level. The town occupies a strategic location where the Anoia River cuts through the landscape, creating a natural valley system that has shaped the local terrain for millennia. The surrounding topography is characterized by rolling hills and gentle slopes that rise gradually toward the northeast, where the terrain becomes more pronounced as it approaches the Pyrenean mountain system. The landscape around Capellades features a mixed terrain of agricultural plains interspersed with low hills and ridges. To the south and west, the land opens up into broader valleys that extend toward the Mediterranean coastal regions. These areas display relatively gentle gradients with occasional limestone outcroppings that are typical of the Catalonian interior. The Anoia River valley itself provides a natural corridor through the landscape, with fertile alluvial soils flanking the waterway.Geological and Terrain Characteristics
The bedrock geology consists primarily of sedimentary formations, including limestone, sandstone, and clay deposits that date back to various geological periods. This geological foundation creates a stable base for construction while also contributing to the area's characteristic rolling topography. The terrain shows evidence of both fluvial erosion from the Anoia River system and broader weathering processes that have smoothed many of the sharper relief features over geological time. Vegetation in the region reflects the Mediterranean climate, with oak woodlands covering many of the hillsides and agricultural crops occupying the flatter valley floors. The natural vegetation patterns often indicate drainage patterns and soil conditions, with denser forest cover typically found on north-facing slopes and more sparse vegetation on southern exposures.Optimal Areas for Large-Scale Solar Development
The most promising locations for extensive solar photovoltaic installations lie on the gently sloping hillsides south and southwest of Capellades. These elevated areas offer several advantages including consistent southern exposure, minimal shading from surrounding terrain features, and slopes that are gentle enough to accommodate large arrays without excessive grading requirements. The hills rising to elevations between 300 and 450 meters provide particularly suitable conditions, as they remain above the river valley's occasional fog while maintaining reasonable accessibility. The broad plateau areas extending westward toward Igualada present another excellent opportunity for solar development. These relatively flat expanses require minimal terrain modification and offer extensive continuous areas that could support utility-scale installations. The agricultural lands in these areas typically have good road access and existing electrical infrastructure nearby, which reduces development costs and complexity. Areas to the southeast, where the terrain opens toward the Penedès region, also show strong potential for solar projects. The landscape here features long, gentle ridges with predominantly southern aspects that would maximize solar exposure throughout the day. The spacing between these ridges is sufficient to prevent inter-array shading while the elevated positions provide natural drainage and reduce concerns about flooding or moisture accumulation. The immediate vicinity of existing industrial areas near Capellades could accommodate smaller but still significant solar installations, particularly on brownfield sites or areas already disturbed by previous development. These locations benefit from proximity to electrical grid connections and transportation infrastructure, making them attractive despite potentially smaller available areas compared to the rural hillside locations.Spain solar PV Stats as a country
Spain ranks 10th in the world for cumulative solar PV capacity, with 15,952 total MW's of solar PV installed. This means that 9.00% of Spain's total energy as a country comes from solar PV (that's 6th in the world). Each year Spain is generating 237 Watts from solar PV per capita (Spain ranks 20th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Spain?
Yes, there are several incentives for businesses wanting to install solar energy in Spain. These include the following:
1. The Spanish government offers a feed-in tariff (FIT) for businesses that install solar energy systems. This FIT guarantees a fixed price per kWh of electricity generated by the system over a period of 20 years.
2. Businesses can also benefit from tax deductions and other financial incentives when installing solar energy systems in Spain.
3. Companies may be eligible for grants or subsidies from regional governments or local authorities to help cover the cost of installation and maintenance of their solar energy systems.
4. Businesses may also be able to take advantage of net metering, which allows them to sell excess electricity generated by their solar energy system back into the grid at market prices, thus reducing their overall electricity costs even further.
