Marinilla, Antioquia, Colombia presents an excellent location for year-round solar energy generation, with consistently high electricity output throughout all seasons. The solar production data shows remarkably stable performance, ranging from 5.14 kWh per day per kW of installed capacity in spring to 5.65 kWh per day per kW during summer months.
Year-Round Solar Performance
The location demonstrates exceptional consistency in solar energy production across all meteorological seasons. Summer provides the highest output at 5.65 kWh/day per kW, followed closely by autumn at 5.46 kWh/day per kW. Winter maintains strong production at 5.28 kWh/day per kW, while spring shows the lowest but still substantial output at 5.14 kWh/day per kW. This minimal seasonal variation of only 0.51 kWh difference between the best and worst performing seasons makes Marinilla particularly attractive for solar installations. The tropical location ensures reliable solar energy generation throughout the year, with summer and autumn being the optimal periods for maximum electricity production.Optimal Installation Configuration
For fixed panel installations at this location, the ideal angle to tilt panels to maximize total year-round production is 5 degrees South. This shallow tilt angle is typical for locations close to the equator and helps optimize solar collection throughout the year by accounting for the sun's path and seasonal variations in solar irradiance.Environmental and Weather Considerations
Several local factors could potentially impact solar production efficiency in Marinilla and require careful consideration during installation:- Tropical rainfall patterns: The wet season can bring heavy rainfall and increased cloud cover, potentially reducing solar irradiance during certain periods
- High humidity levels: Consistent tropical humidity may lead to moisture-related issues with electrical components and potential corrosion over time
- Dust and particulate accumulation: Dry season conditions can result in dust buildup on solar panels, reducing their efficiency
- Vegetation growth: The tropical climate supports rapid plant growth that could create shading issues if not properly managed
Preventative Measures for Optimal Performance
To ensure maximum energy production and system longevity, several preventative measures should be implemented: Regular cleaning schedules are essential to remove dust, pollen, and other debris that accumulate on panel surfaces. Installing panels with adequate spacing and ventilation helps combat humidity-related issues and prevents overheating. Proper drainage systems around installations prevent water pooling during heavy rains. Using corrosion-resistant materials and protective coatings on all metal components helps withstand the humid tropical environment. Regular vegetation management around the solar installation site prevents shading issues as plants grow rapidly in this climate. Implementing monitoring systems allows for early detection of performance issues, while choosing high-quality inverters and electrical components rated for tropical conditions ensures reliable operation. Proper grounding and surge protection systems are particularly important given the potential for tropical storms and electrical activity in the region.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 Marinilla
Seasonal solar PV output for Latitude: 6.1736, Longitude: -75.3362 (Marinilla, 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 5° South in Marinilla, Colombia
To maximize your solar PV system's energy output in Marinilla, Colombia (Lat/Long 6.1736, -75.3362) throughout the year, you should tilt your panels at an angle of 5° 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 Marinilla, 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 Marinilla, Colombia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 5° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 10° North in Summer | 12° South in Autumn | 22° South in Winter | 1° North 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 Marinilla, Colombia
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 Marinilla, Colombia.
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 Marinilla, Colombia
Topographical Features of Marinilla
Marinilla sits in the eastern part of the AburrĂ¡ Valley in Antioquia, Colombia, positioned on the western slopes of the Cordillera Central mountain range. The town itself rests at an elevation of approximately 2,100 meters above sea level, placing it within the temperate zone of the Andean region. The surrounding landscape is characterized by rolling hills, gentle valleys, and moderate slopes that define much of the eastern Antioquia region.
The terrain around Marinilla features a mix of agricultural lands, pastures, and forested areas spread across undulating topography. The area benefits from relatively stable geological conditions, with the underlying bedrock consisting primarily of metamorphic and igneous formations typical of the Colombian Andes. The climate remains fairly consistent throughout the year due to its equatorial location and elevation, with moderate temperatures and distinct wet and dry seasons.
Drainage and Water Features
Several small streams and tributaries flow through the region, eventually draining toward the Magdalena River system. The Marinilla River runs through the municipality, creating small valleys and floodplains that have historically supported agricultural activities. These waterways have carved gentle channels through the landscape, creating a varied topography of ridges and valleys that influences local microclimates and land use patterns.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations around Marinilla would be the relatively flat to gently sloping areas found on the broader valley floors and plateau-like sections of the surrounding hills. These areas typically offer the best combination of accessible terrain, minimal shading from topographical features, and practical construction conditions.
The agricultural plains extending northeast and southeast of the town center present particularly favorable conditions for solar development. These areas feature gentle gradients that would require minimal earthwork for panel installation while providing adequate drainage during the rainy season. The open character of these landscapes also reduces concerns about shading from nearby hills or vegetation.
South-facing slopes with gradients between 5 and 15 degrees would be especially advantageous for solar installations, as they naturally orient panels toward optimal sun exposure throughout the day. Several such slopes exist in the hills surrounding Marinilla, particularly on the northern and western sides of the valley where the terrain opens up toward the broader AburrĂ¡ Valley system.
Areas to avoid for large-scale solar development would include the steeper hillsides above 20-degree gradients, narrow valley bottoms prone to morning fog or afternoon shadows, and locations with significant forest cover that would require extensive clearing. The more mountainous terrain to the east, where slopes become increasingly steep as they approach the higher peaks of the Cordillera Central, would present both technical and environmental challenges for solar installations.
