Graph of hourly avg kWh electricity output per kW of Solar PV installed in Alzira, Spain (by season)

The location of Alzira, Valencia, Spain, situated at latitude 39.1488 and longitude -0.4294, offers a promising environment for solar PV energy generation throughout the year. This Mediterranean city experiences varying levels of solar potential across different seasons, making it an interesting case study for renewable energy enthusiasts.

Seasonal Solar Performance

Solar energy production in Alzira follows a predictable pattern, with peak performance during the summer months. For each kilowatt of installed solar capacity, the location yields an impressive 7.37 kWh per day in summer. Spring follows as the second most productive season, generating 5.54 kWh daily. Autumn sees a decrease in output to 3.94 kWh per day, while winter experiences the lowest production at 2.72 kWh daily.

These figures indicate that Alzira's solar potential is particularly strong from late spring through early autumn. During this period, longer days and clearer skies contribute to optimal energy generation. However, the substantial winter output suggests that solar remains a viable energy source year-round, albeit with reduced efficiency during the colder months.

Optimal Panel Installation

To maximize solar energy capture throughout the year, fixed solar panels in Alzira should be tilted at a 34-degree angle facing south. This carefully calculated angle takes into account the city's latitude, the Earth's orbit, and seasonal variations in solar elevation. By adhering to this optimal tilt, residents and businesses can ensure they're harnessing the maximum possible solar energy across all seasons.

Environmental Considerations

While Alzira's climate is generally favorable for solar energy production, there are a few environmental factors to consider. The region occasionally experiences dust storms blown in from the Sahara Desert, which can temporarily reduce panel efficiency. Regular cleaning and maintenance can mitigate this issue. Additionally, the area's proximity to the Mediterranean Sea means there's a risk of salt spray accumulation on panels near the coast, potentially causing corrosion over time.

To address these challenges, installers should consider using panels with anti-reflective and hydrophobic coatings. These features help repel dust and salt, maintaining optimal performance. Furthermore, implementing a routine cleaning schedule and using specialized cleaning solutions can prolong the life and efficiency of solar installations in this coastal Mediterranean environment.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 34° South in Alzira, Spain

To maximize your solar PV system's energy output in Alzira, Spain (Lat/Long 39.1488, -0.4294) 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 Alzira, 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 Alzira, 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
23° South in Summer 43° South in Autumn 54° South in Winter 31° South in Spring

Assuming you can modify the tilt angle of your solar PV panels throughout the year, you can optimize your solar generation in Alzira, Spain as follows: In Summer, set the angle of your panels to 23° facing South. In Autumn, tilt panels to 43° facing South for maximum generation. During Winter, adjust your solar panels to a 54° angle towards the South for optimal energy production. Lastly, in Spring, position your panels at a 31° angle facing South to capture the most solar energy in Alzira, Spain.

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.

Topography for solar PV around Alzira, Spain

Alzira, a city in eastern Spain, is situated in a diverse topographical region characterized by a mix of flat plains and rolling hills. The immediate area around Alzira is predominantly flat, as it sits in the fertile Ribera Alta comarca within the larger Valencia province. This flat terrain is part of the expansive coastal plain that stretches along much of Spain's Mediterranean coast. To the west and northwest of Alzira, the landscape gradually transitions into more elevated terrain. Here, one can find gently rolling hills that eventually give way to more pronounced mountainous areas. These hills are part of the larger Sistema Ibérico mountain range, which runs through much of eastern Spain. The Júcar River, a significant watercourse in the region, flows near Alzira, carving a valley through the surrounding landscape. This river has played a crucial role in shaping the local topography, creating alluvial plains that are ideal for agriculture.

Potential for Solar PV Development

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations would combine flat or gently sloping terrain, ample sunlight exposure, and minimal environmental or agricultural impact. The flat plains surrounding Alzira, particularly to the east and southeast, present promising opportunities for solar PV development. These areas benefit from the region's abundant sunshine and offer large, unobstructed spaces that could accommodate extensive solar arrays. The relatively level ground would minimize the need for extensive land preparation, potentially reducing installation costs. Some of the gently rolling hills to the west of Alzira might also be suitable for solar PV installations. While these areas may require more careful site selection and planning to maximize sun exposure, they could offer the advantage of being less agriculturally productive than the fertile plains, thus minimizing conflicts with food production. It's worth noting that any large-scale solar development would need to carefully consider environmental impacts, particularly given the ecological importance of the Júcar River valley. Areas away from critical habitats and water resources would be preferable. Ultimately, the most suitable locations for solar PV near Alzira would likely be found in the less agriculturally productive flat areas or on gentle slopes, where the installation would have minimal impact on existing land use while benefiting from the region's favorable solar conditions.

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.
