Ideally tilt fixed solar panels 32° South in Los Palacios Y Villafranca, Spain

To maximize your solar PV system's energy output in Los Palacios Y Villafranca, Spain (Lat/Long 37.1645, -5.9232) throughout the year, you should tilt your panels at an angle of 32° 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 Los Palacios Y Villafranca, 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 Los Palacios Y Villafranca, Spain. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
21° South in Summer	42° South in Autumn	52° South in Winter	30° 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.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Los Palacios Y Villafranca, Spain

Los Palacios y Villafranca is located in the southwestern part of Spain, in the province of Seville, Andalusia. The topography of this area is characterized by its relatively flat terrain, typical of the Guadalquivir River valley. The town itself sits at an elevation of approximately 10 meters (33 feet) above sea level, with the surrounding landscape consisting primarily of gently rolling plains and agricultural fields. To the north and east of Los Palacios y Villafranca, the land gradually rises towards the foothills of the Sierra Morena mountain range. However, this elevation change is subtle and occurs over a considerable distance. To the south and west, the terrain remains predominantly flat as it extends towards the coastal regions of Cádiz province.

Suitability for Large-Scale Solar PV

The areas surrounding Los Palacios y Villafranca offer excellent potential for large-scale solar photovoltaic (PV) installations due to several favorable factors: Firstly, the flat terrain of the Guadalquivir valley provides ample space for the deployment of extensive solar panel arrays without the need for significant land preparation or terracing. This reduces installation costs and simplifies maintenance procedures. Secondly, the region experiences a high number of sunny days throughout the year, with Andalusia being one of the sunniest areas in Europe. This abundance of solar radiation ensures optimal energy production from PV installations. The most suitable areas for large-scale solar PV projects would be the open agricultural lands to the east and southeast of Los Palacios y Villafranca. These areas offer vast, unobstructed spaces with minimal shading from natural or man-made structures. Additionally, the slightly elevated terrain in these directions may provide a marginal increase in solar exposure. It's worth noting that while the immediate surroundings of Los Palacios y Villafranca are well-suited for solar PV, care should be taken to balance energy production with the preservation of valuable agricultural land. Ideal locations would be those that are less productive for farming or areas that can accommodate dual-use systems, allowing for both solar energy generation and continued agricultural activities.
