Solar PV Analysis of Neiva, Colombia
Neiva, Huila Department, Colombia, located at 2.9208° N, 75.283° W, is an excellent location for generating energy via solar PV year-round. Here's a summary in plain language:
Solar Potential:
The location shows consistently high solar energy production throughout the year, with only slight variations between seasons:
- Summer: 4.51 kWh/day
- Autumn: 5.01 kWh/day
- Winter: 4.85 kWh/day
- Spring: 4.53 kWh/day
These numbers indicate that Neiva receives abundant sunlight year-round, making it an ideal spot for solar energy production. The most productive season is autumn, followed closely by winter, while summer and spring have slightly lower but still very good output.
Ideal Panel Angle:
For fixed panel installations, the ideal tilt angle to maximize year-round production is 3 degrees facing South. This nearly flat orientation is due to Neiva's proximity to the equator, where the sun's path is more directly overhead throughout the year.
Environmental Factors:
There are a few environmental factors that could potentially impact solar production in Neiva:
1. Rainfall: Being in the tropics, Neiva experiences wet and dry seasons. During the wet season, increased cloud cover and rainfall could slightly reduce solar output. To mitigate this:
- Install panels at the recommended 3-degree tilt to help rainwater runoff and prevent water accumulation.
- Use high-quality, water-resistant solar panels and equipment.
- Implement a regular cleaning schedule to remove any debris or dirt that may accumulate during rainy periods.
2. Heat: High temperatures in tropical regions can potentially reduce solar panel efficiency. To address this:
- Choose solar panels designed for high-temperature performance.
- Ensure proper ventilation behind the panels during installation to allow heat dissipation.
3. Dust and Pollen: Tropical regions can have high levels of airborne particles. To maintain efficiency:
- Implement a regular cleaning schedule for the panels.
- Consider installing automated cleaning systems for larger installations.
Despite these factors, Neiva's location remains highly favorable for solar energy production. The consistent year-round sunlight and the ability to mitigate potential issues make it an excellent choice for solar PV installations.
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 173 locations across Colombia. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Neiva
Seasonal solar PV output for Latitude: 2.9208, Longitude: -75.283 (Neiva, 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 3° South in Neiva, Colombia
To maximize your solar PV system's energy output in Neiva, Colombia (Lat/Long 2.9208, -75.283) throughout the year, you should tilt your panels at an angle of 3° 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 Neiva, 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 Neiva, Colombia. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 3° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 13° North in Summer | 9° South in Autumn | 19° South in Winter | 4° 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 Neiva, 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 Neiva, 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 Neiva, Colombia
Neiva, Colombia is located in the upper Magdalena River valley, surrounded by the Andes Mountains. The topography around Neiva is characterized by:
1. Flat to gently rolling terrain in the immediate vicinity of the city
2. The Magdalena River running through the area
3. Foothills of the Andes Mountains rising to the east and west
4. Higher mountain ranges further east (Eastern Cordillera) and west (Central Cordillera)
For large-scale solar PV installations, the most suitable areas nearby would likely be:
1. Flat or gently sloping areas in the Magdalena River valley: These areas offer relatively even terrain, which is ideal for solar panel installation. They are also likely to receive consistent sunlight throughout the day.
2. Lower elevation foothills: Areas with slight elevation but not too steep might provide good locations for solar farms, as they can potentially receive more direct sunlight and have less risk of shading from nearby terrain.
3. Areas to the north and south of Neiva along the valley: These regions likely share similar topographical characteristics and may offer large, open spaces suitable for solar installations.
4. Agricultural lands that are less productive or unused: These could potentially be repurposed for solar energy production, provided they meet other criteria such as proximity to power infrastructure.
When considering specific locations for large-scale solar PV, it's important to also take into account:
1. Proximity to existing electrical infrastructure
2. Local climate conditions, including cloud cover and rainfall patterns
3. Land ownership and use regulations
4. Environmental impact and biodiversity considerations
5. Accessibility for construction and maintenance
A detailed site survey and environmental impact assessment would be necessary to determine the most appropriate locations for large-scale solar PV installations in the area around Neiva.
