Solar PV Analysis of Zamora, Spain
Solar Energy Potential in Zamora, Castille and León, Spain
Zamora, Castille and León, Spain, located at latitude 41.5° North and longitude 5.7438° West, offers a promising location for solar energy generation. This city in the Northern Temperate Zone experiences significant seasonal variations in solar energy production, which is typical for its latitude.
Summer stands out as the most productive season for solar energy in Zamora, Castille and León, with an impressive daily output of 8.12 kWh per kW of installed solar capacity. This high yield is due to longer daylight hours and more direct sunlight during the summer months. Spring follows as the second-most productive season, generating 6.09 kWh per day, benefiting from increasing daylight and generally clear skies.
Autumn sees a noticeable decrease in solar energy production, with 4.03 kWh per day. This reduction is attributed to shorter days and the sun's lower position in the sky. Winter presents the greatest challenge for solar energy generation in Zamora, Castille and León, with only 2.36 kWh produced daily per kW of installed capacity. The low winter output is due to shorter days, the sun's low angle, and potentially increased cloud cover.
Optimizing Solar Panel Installation
To maximize year-round solar energy production in Zamora, Castille and León, fixed solar panels should be tilted at a 35-degree angle facing south. This optimal angle takes into account the sun's position throughout the year, ensuring the panels capture as much sunlight as possible across all seasons.
Environmental and Weather Considerations
While Zamora generally offers favorable conditions for solar energy production, there are some factors to consider:
- Dust and pollen: Zamora's semi-arid climate can lead to dust accumulation on solar panels, potentially reducing their efficiency. Regular cleaning and maintenance can mitigate this issue.
- Winter fog: The city occasionally experiences fog during winter months, which can temporarily reduce solar output. While this cannot be prevented, using high-quality panels that perform well in diffuse light conditions can help maintain some energy production during foggy periods.
Despite these minor challenges, Zamora's climate and latitude make it a suitable location for solar energy production, especially during the spring and summer months. With proper installation and maintenance, solar PV systems in Zamora can provide a significant and reliable source of renewable energy throughout the year.
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 Zamora
Seasonal solar PV output for Latitude: 41.5, Longitude: -5.7438 (Zamora, 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 35° South in Zamora, Spain
To maximize your solar PV system's energy output in Zamora, Spain (Lat/Long 41.5, -5.7438) throughout the year, you should tilt your panels at an angle of 35° 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 Zamora, 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 Zamora, Spain. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° 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 Zamora, 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 Zamora, 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 Zamora, Spain
The area around Zamora, Spain, is characterized by a diverse and interesting topography. The city itself is situated on a rocky hill overlooking the Duero River, which is one of the most prominent features of the landscape. This elevated position gives Zamora a commanding view of the surrounding terrain.
To the north and east of Zamora, the land gradually transitions into the expansive Meseta Central, a large plateau that dominates much of central Spain. This plateau is generally flat to gently rolling, with occasional low hills and shallow valleys. The terrain here is relatively open, with sparse vegetation consisting mainly of grasses and scattered shrubs.
South of the city, the landscape becomes more varied. The Duero River valley widens, creating fertile lowlands that have been cultivated for centuries. Beyond these river plains, the terrain begins to rise again, forming a series of hills and small mountain ranges that mark the northern edge of the Sistema Central mountain range.
To the west, the topography becomes increasingly rugged as it approaches the border with Portugal. This area is characterized by more pronounced hills, deeper valleys, and areas of denser forest cover.
Suitability for Large-Scale Solar PV
For large-scale solar photovoltaic (PV) installations, the most suitable areas near Zamora would likely be found in the flatter, more open regions to the north and east of the city. These areas on the Meseta Central offer several advantages for solar energy production:
- Ample flat or gently sloping land, which is ideal for the installation of large solar panel arrays
- Minimal shading from geographical features or vegetation
- Good sun exposure throughout the year due to the region's relatively high altitude and clear skies
- Lower population density, potentially reducing conflicts with other land uses
The areas immediately south of Zamora, along the Duero River valley, might also be suitable for solar PV installations. However, these lands are often used for agriculture, which could create competition for space. The more rugged terrain to the west and far south would generally be less ideal for large-scale solar projects due to the increased complexity and cost of installation on uneven ground.
It's important to note that while topography is a crucial factor in determining suitable locations for solar PV, other considerations such as proximity to electrical infrastructure, local regulations, and environmental impact assessments would also play significant roles in the final site selection for any large-scale solar energy project.

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.
