Ideally tilt fixed solar panels 35° South in Colmenar Viejo, Spain
To maximize your solar PV system's energy output in Colmenar Viejo, Spain (Lat/Long 40.6599, -3.7638) 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 Colmenar Viejo, 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 Colmenar Viejo, 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 |
|---|---|---|---|
| 25° 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 Colmenar Viejo, 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 Colmenar Viejo, Spain
Colmenar Viejo, located in the Madrid region of Spain, is situated in an area with diverse and interesting topography. The town itself sits on a plateau at an elevation of approximately 880 meters above sea level. This plateau is part of the southern foothills of the Sierra de Guadarrama mountain range, which forms a striking backdrop to the north of the town. The surrounding landscape is characterized by gently rolling hills and wide, open spaces. To the south and east of Colmenar Viejo, the terrain gradually descends towards the Madrid basin, creating a mix of undulating countryside and flatter areas. The region features a combination of Mediterranean scrubland, known as "matorral," interspersed with grasslands and scattered oak trees, typical of the dehesa landscape found in central Spain. Several streams and small rivers cut through the area, creating shallow valleys and contributing to the varied topography. The Manzanares River, one of the most significant waterways in the region, flows to the east of Colmenar Viejo, carving a more pronounced valley as it heads southward towards Madrid.
Potential Areas for Large-Scale Solar PV
When considering areas suitable for large-scale solar photovoltaic (PV) installations near Colmenar Viejo, several factors come into play. The ideal locations would combine favorable topography with good sun exposure and minimal environmental impact. The gently sloping areas to the south and southeast of Colmenar Viejo present promising opportunities for solar PV development. These regions benefit from a southerly aspect, which is optimal for solar energy capture in the Northern Hemisphere. The gradual incline of the land in these directions also helps to minimize shading between solar panels, allowing for more efficient use of space. Areas of relatively flat terrain found on the plateau surrounding Colmenar Viejo could also be suitable for solar installations. These locations offer the advantage of easier construction and maintenance access, which can be crucial for large-scale projects. It's important to note that while the topography around Colmenar Viejo offers potential for solar PV development, any large-scale installations would need to be carefully planned to balance energy production with environmental conservation. The region's natural beauty and ecological significance, particularly in areas closer to the Sierra de Guadarrama, would need to be taken into account when selecting specific sites for solar farms.Spain solar PV Stats as a country
