Barrancas, La Guajira Department, Colombia presents an excellent location for year-round solar energy generation, with consistently strong performance across all seasons. Located in the tropical zone at coordinates 10.9538°N, -72.7893°W, this area benefits from the reliable sunlight patterns typical of equatorial regions.
Solar Energy Production Performance
The solar energy output at Barrancas demonstrates remarkable consistency throughout the year. Summer delivers the highest production at 5.90 kWh per day per kW of installed solar capacity, followed closely by winter at 5.68 kWh per day. Spring and autumn show slightly lower but still excellent figures of 5.51 and 5.54 kWh per day respectively. This minimal seasonal variation makes Barrancas particularly attractive for solar installations, as energy production remains predictable and strong year-round. The difference between the best and worst performing seasons is only about 7%, which is exceptionally small compared to solar installations in temperate climates.Optimal Panel Configuration
For maximum year-round solar production at Barrancas, La Guajira Department, solar panels should be installed at a fixed tilt angle of 10 degrees facing south. This relatively shallow angle is calculated to optimize total annual energy capture by accounting for the sun's path throughout the year and weighting the angles based on solar irradiance data.Environmental and Weather Considerations
Several local factors could potentially impact solar energy production in Barrancas and require careful planning during installation:- Dust and Sand Accumulation: The coastal location and arid climate typical of northern Colombia can lead to significant dust buildup on solar panels, reducing efficiency by 10-20% if left unaddressed
- Salt Air Corrosion: Proximity to the Caribbean coast means salt-laden air can accelerate corrosion of metal components and electrical connections
- High Humidity and Temperature: Tropical conditions can stress electrical components and reduce panel efficiency, particularly during peak heat periods
- Seasonal Rainfall Patterns: While the wet season provides natural panel cleaning, intense tropical downpours can pose installation and maintenance challenges
Preventative Measures for Optimal Performance
To maximize solar energy production despite these challenges, several protective measures should be implemented:- Anti-Corrosion Materials: Use marine-grade aluminum frames and stainless steel mounting hardware specifically designed for coastal environments
- Enhanced Ventilation: Install panels with adequate spacing beneath to promote air circulation and reduce operating temperatures
- Regular Cleaning Schedule: Implement monthly panel cleaning during dry seasons, with more frequent cleaning during dusty periods
- Protective Coatings: Apply specialized anti-soiling coatings to panel surfaces to reduce dust adhesion and facilitate natural cleaning by rain
- Quality Electrical Components: Use weatherproof inverters and electrical connections rated for high humidity and temperature fluctuations
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Solar output per kW of installed solar PV by season in Barrancas
Seasonal solar PV output for Latitude: 10.9538, Longitude: -72.7893 (Barrancas, Colombia), 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 10° South in Barrancas, Colombia
To maximize your solar PV system's energy output in Barrancas, Colombia (Lat/Long 10.9538, -72.7893) throughout the year, you should tilt your panels at an angle of 10° 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 Barrancas, Colombia
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 Barrancas, Colombia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 10° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 5° North in Summer | 17° South in Autumn | 26° South in Winter | 5° 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.

- 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 Barrancas, Colombia
Topographical Features of Barrancas, Colombia
Barrancas sits in the northern region of La Guajira department, positioned within the expansive Guajira Peninsula that extends toward the Caribbean Sea. This area forms part of the broader Caribbean coastal plain, characterized by relatively flat to gently undulating terrain that gradually transitions from the foothills of the Sierra Nevada de Santa Marta mountain range to the east toward the more arid lowlands approaching the Venezuelan border. The immediate landscape around Barrancas displays a semi-arid topography with scattered low hills and broad valleys. The terrain consists primarily of sedimentary formations that create a rolling landscape punctuated by occasional mesa-like elevations and gentle ridges. These geological features result from millions of years of erosion and weathering in this tropical dry forest ecosystem, creating a mosaic of elevated plateaus separated by shallow depressions and seasonal drainage channels. The elevation in the Barrancas area ranges from approximately 100 to 300 meters above sea level, with the terrain sloping gradually northward toward the Caribbean coast. The landscape exhibits the characteristic features of the Guajira region, including expansive plains interrupted by isolated hills and low mountain ridges that run roughly parallel to the coastline.Optimal Areas for Large-Scale Solar Development
The broad, relatively flat plains extending northwest and northeast of Barrancas present the most promising opportunities for large-scale solar photovoltaic installations. These areas offer extensive tracts of level ground with minimal topographical obstacles, reducing both construction costs and technical challenges associated with panel installation and maintenance access. The elevated plateaus and mesa tops scattered throughout the region provide excellent alternative sites for solar development. These locations benefit from consistent exposure to prevailing winds, which help maintain optimal panel temperatures, while their elevated positions minimize potential shading from surrounding terrain features. The stable geological foundation of these plateaus also supports the substantial infrastructure requirements of utility-scale solar installations. Areas immediately south and southeast of Barrancas, where the terrain transitions into broader valleys between the scattered hill formations, offer additional suitable locations. These valley floors typically provide the extensive flat areas necessary for large solar arrays while maintaining good drainage characteristics that prevent water accumulation during the region's brief wet periods. The gentle slopes facing south and southwest throughout the area can accommodate solar installations designed to optimize panel orientation. These naturally inclined surfaces often require minimal grading and earthwork, reducing development costs while providing ideal angles for maximum solar collection throughout the day. Transportation infrastructure accessibility significantly enhances the viability of potential solar sites in this region. Areas within reasonable proximity to existing road networks, particularly those connecting to the main transportation corridors linking Barrancas to regional population centers, offer practical advantages for construction logistics and ongoing operational requirements.Colombia solar PV Stats as a country
