Soria, Castille and León, Spain, located at 41.7635°N, -2.4749°E, presents a varied landscape for solar energy production throughout the year. This location in the Northern Temperate Zone experiences significant seasonal fluctuations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Performance
The solar energy potential in Soria varies considerably across seasons. Summer stands out as the most productive period, with an impressive daily output of 7.65 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 5.59 kWh/day. Autumn sees a notable decrease to 3.77 kWh/day, while winter experiences the lowest output at 2.31 kWh/day.
These figures indicate that Soria's location is quite favorable for solar energy production during the warmer months, particularly from late spring through early autumn. However, the significant drop in winter output suggests that supplementary energy sources may be necessary during the colder months to meet consistent energy demands.
Optimal Panel Installation
For maximizing year-round solar energy production in Soria, Castille and León, fixed solar panels should be tilted at a 36-degree angle facing south. This optimal angle has been calculated to capture the most sunlight throughout the year, considering the location's latitude and the Earth's elliptical orbit.
Environmental Considerations
While Soria's climate is generally conducive to solar energy production, there are some environmental factors to consider:
- Dust and pollen: Soria's semi-arid climate can lead to dust accumulation on panels, potentially reducing efficiency. Regular cleaning and maintenance can mitigate this issue.
- Snow: Winter snowfall, though not extreme, can temporarily cover panels. Installing panels at the optimal angle helps snow slide off more easily.
To enhance solar production in Soria, Castille and León, consider implementing tracking systems to follow the sun's path, especially beneficial during the longer summer days. Additionally, using high-efficiency panels and ensuring proper ventilation can help maximize output, particularly during the intense summer heat.
Overall, while Soria faces challenges in winter solar production, its location offers substantial potential for solar energy generation, especially from spring through autumn. With proper installation techniques and regular maintenance, solar PV systems can be a viable and efficient energy source in this Spanish city.

Solar output per kW of installed solar PV by season in Soria
Seasonal solar PV output for Latitude: 41.7635, Longitude: -2.4749 (Soria, 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 Soria, Spain
To maximize your solar PV system's energy output in Soria, Spain (Lat/Long 41.7635, -2.4749) 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 Soria, 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 Soria, 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 |
|---|---|---|---|
| 26° South in Summer | 46° 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 Soria, 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 Soria, 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 Soria, Spain
Soria, a city in north-central Spain, is situated in a region characterized by diverse and interesting topography. The city itself sits on a plateau at an elevation of around 1,065 meters (3,494 feet) above sea level. This high-altitude location contributes to the area's continental climate, with cold winters and warm summers. The surrounding landscape is a mix of rolling hills, plateaus, and river valleys. To the north and east of Soria, the terrain becomes more rugged as it transitions into the Iberian System, a complex series of mountain ranges. These mountains, while not extremely high, create a varied landscape with peaks, valleys, and forested areas.
River Valleys and Plains
One of the most prominent features of Soria's topography is the Duero River, which flows through the city. The river has carved out a wide valley, creating fertile plains that have been used for agriculture for centuries. As the Duero continues westward, it forms a broader basin with gentler slopes and more expansive flatlands. To the south and west of Soria, the landscape gradually flattens out into the northern reaches of the Meseta Central, the vast central plateau that dominates much of inland Spain. This area is characterized by wide-open spaces, gently undulating terrain, and occasional isolated hills or low mountain ranges.Potential for Solar PV Development
When considering areas near Soria for large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would combine ample sunlight exposure, relatively flat terrain, and good accessibility. The plains and gentle slopes to the south and west of Soria present some of the most promising areas for solar PV development. These regions benefit from the following characteristics: 1. Open landscape with minimal shading from geographical features 2. Generally flat or gently sloping terrain, reducing installation costs and complexity 3. Good road access for construction and maintenance 4. Lower agricultural value compared to the fertile river valleys Specific areas that might be particularly suitable include the plains around towns like Almazán, south of Soria, or the open areas west of the city towards Burgo de Osma. These locations offer expansive, unobstructed spaces that could accommodate large solar arrays. It's worth noting that while the mountainous areas to the north and east receive plenty of sunlight, their rugged terrain and often forested nature make them less ideal for large-scale solar installations. However, these regions might be suitable for smaller, distributed solar projects. Any solar development would, of course, need to be balanced with environmental considerations, agricultural needs, and local regulations. But given Spain's commitment to renewable energy and the abundant solar resources in the region, the areas around Soria hold significant potential for solar PV projects.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.
