The location of Valdemoro, Madrid, Spain, situated at latitude 40.1859 and longitude -3.6754, offers a varied potential for solar energy generation throughout the year. This Northern Temperate Zone location experiences significant seasonal fluctuations in solar output, which can impact the overall efficiency of solar PV installations.
Seasonal Solar Performance
Solar energy production in Valdemoro reaches its peak during the summer months, with an impressive daily output of 8.01 kWh per kW of installed solar capacity. Spring follows as the second-most productive season, generating 5.85 kWh/day. Autumn sees a notable decrease to 4.06 kWh/day, while winter experiences the lowest output at 2.45 kWh/day.
These figures indicate that Valdemoro is particularly well-suited for solar energy production during the warmer months, 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
To maximize year-round solar energy production in Valdemoro, Madrid, fixed solar panels should be installed at a tilt angle of 34 degrees facing south. This orientation ensures the best overall performance across all seasons, balancing the high summer sun with the lower winter sun angle.
Environmental Considerations
While Valdemoro generally offers favorable conditions for solar energy production, there are some environmental factors to consider:
- Dust and pollen: The region's dry climate can lead to dust accumulation on panels, potentially reducing efficiency. Regular cleaning and maintenance can mitigate this issue.
- Temperature extremes: Hot summer days may slightly reduce panel efficiency, while occasional winter frosts could impact system components. Using high-quality, temperature-resistant equipment is advisable.
To address these factors, consider implementing automated cleaning systems, selecting heat-resistant solar panels, and ensuring proper ventilation for inverters and other components. Additionally, a robust monitoring system can help detect and address any performance issues promptly.
Overall, Valdemoro presents a good location for solar PV installations, with strong potential during warmer months and manageable challenges that can be addressed through proper planning and maintenance.

Ideally tilt fixed solar panels 34° South in Valdemoro, Spain
To maximize your solar PV system's energy output in Valdemoro, Spain (Lat/Long 40.1859, -3.6754) throughout the year, you should tilt your panels at an angle of 34° 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 Valdemoro, 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 Valdemoro, Spain. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 24° South in Summer | 45° South in Autumn | 55° South in Winter | 33° 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 Valdemoro, 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 Valdemoro, 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 Valdemoro, Spain
The topography around Valdemoro, Spain, is characterized by a mix of gently rolling plains and low hills typical of the central Meseta region of the Iberian Peninsula. Situated approximately 27 kilometers south of Madrid, Valdemoro lies in a transitional zone between the Tagus River basin and the foothills of the Sistema Central mountain range. The landscape surrounding Valdemoro is predominantly flat to slightly undulating, with occasional shallow valleys and low ridges. The terrain gradually rises towards the north and west, while it becomes more level as you move south and east. The area's elevation ranges from about 600 to 700 meters above sea level, providing a relatively uniform topographical profile.
Suitability for Large-Scale Solar PV
Several areas near Valdemoro would be well-suited for large-scale solar photovoltaic (PV) installations. The regions to the south and southeast of Valdemoro are particularly promising due to their flatter terrain and open spaces. These areas benefit from fewer topographical obstacles, which could potentially obstruct sunlight or complicate construction. The expansive agricultural lands in the surrounding municipalities, such as Ciempozuelos and SeseƱa, offer ideal conditions for solar farms. These locations provide large, uninterrupted stretches of land with minimal shading from natural features or buildings. The gentle slopes in these areas can also be advantageous for optimal panel orientation towards the sun. Additionally, the regions to the east and northeast of Valdemoro, extending towards Arganda del Rey and Rivas-Vaciamadrid, present favorable conditions for solar PV development. These areas combine relatively flat terrain with good road access, which is crucial for the transportation of equipment and maintenance of solar installations. It's worth noting that while the topography is suitable, other factors such as grid connectivity, local regulations, and environmental considerations would also play crucial roles in determining the final locations for large-scale solar PV projects in the vicinity of Valdemoro.Spain solar PV Stats as a country
