Solar output per kW of installed solar PV by season in Mairena Del Aljarafe

Seasonal solar PV output for Latitude: 37.3434, Longitude: -6.0666 (Mairena Del Aljarafe, 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 32° South in Mairena Del Aljarafe, Spain

To maximize your solar PV system's energy output in Mairena Del Aljarafe, Spain (Lat/Long 37.3434, -6.0666) 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 Mairena Del Aljarafe, 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 Mairena Del Aljarafe, 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.

Calculate solar panel row spacing in Mairena Del Aljarafe, 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 Mairena Del Aljarafe, Spain.

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 Mairena Del Aljarafe, Spain

The area around Mairena del Aljarafe in Spain is characterized by relatively flat to gently rolling terrain. This region is part of the Guadalquivir River Valley, which is known for its wide, open landscapes. The town itself sits on a slight elevation, offering views of the surrounding countryside.

To the east of Mairena del Aljarafe, you'll find the city of Seville and its urban sprawl. The land here is mostly developed, with a mix of residential, commercial, and industrial areas. As you move west and southwest from Mairena del Aljarafe, the landscape becomes more rural, with agricultural fields and scattered small towns dotting the countryside.

The topography in this region is generally favorable for large-scale solar PV installations. The most suitable areas for such projects would be the open, rural lands to the west and southwest of Mairena del Aljarafe. These areas offer several advantages for solar energy development:

1. Flat or gently sloping terrain, which makes construction and maintenance easier
2. Abundant open space, allowing for large arrays of solar panels
3. Good sun exposure, with few natural obstacles to block sunlight
