Solar Energy Production in Coronel Oviedo, Caaguazú Department, Paraguay
Coronel Oviedo, Caaguazú Department, Paraguay, located in the Southern Sub Tropics at coordinates -25.4429, -56.4371, offers promising potential for solar photovoltaic (PV) energy generation throughout the year, though with notable seasonal variations. This location experiences significant differences in solar energy production across the four meteorological seasons. The summer months bring excellent solar production with an average of 7.50 kWh per day for each kilowatt of installed solar capacity. This represents the peak production period when solar panels can operate at their highest efficiency. During spring, production remains strong at 6.07 kWh per day per kilowatt installed. Production decreases considerably during autumn to 5.28 kWh per day, while winter shows the lowest output at just 3.87 kWh per day per kilowatt of installed capacity. This winter reduction represents nearly a 50% decrease compared to summer values, highlighting the significant seasonal variability at this location. For maximizing year-round solar energy production in Coronel Oviedo, Caaguazú Department, fixed solar panels should be installed at a tilt angle of 22 degrees facing North. This specific angle has been calculated to optimize annual energy capture based on the location's latitude and seasonal solar patterns.Environmental and Weather Considerations
Several environmental factors could potentially impact solar production in Coronel Oviedo. The region experiences a subtropical climate with high humidity and occasional heavy rainfall events, particularly during the summer months. These factors may temporarily reduce solar efficiency through:- Dust and dirt accumulation during dry periods followed by rain, creating mud films on panels
- Potential flooding in poorly drained installation areas
- High temperatures in summer that can reduce panel efficiency
Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 55 locations across Paraguay. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 22° North in Coronel Oviedo, Paraguay
To maximize your solar PV system's energy output in Coronel Oviedo, Paraguay (Lat/Long -25.4429, -56.4371) throughout the year, you should tilt your panels at an angle of 22° North 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 Coronel Oviedo, Paraguay
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 Coronel Oviedo, Paraguay. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 22° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 9° North in Summer | 31° North in Autumn | 41° North in Winter | 18° 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 Coronel Oviedo, Paraguay
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 Coronel Oviedo, Paraguay.
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 Coronel Oviedo, Paraguay
The landscape around Coronel Oviedo, Paraguay presents a diverse topography characterized by gently rolling hills, expansive plains, and scattered woodland areas. Located in the Caaguazú Department in the eastern region of Paraguay, this area sits at approximately 125 meters above sea level and features a predominantly flat to undulating terrain that gradually transitions into more pronounced hills toward the east.
Topographical Features
Coronel Oviedo sits within the broader Paraguayan central plateau region, which serves as a transitional zone between the wetter eastern forests and the drier Chaco region to the west. The immediate vicinity around the city consists of modest elevations with gradual slopes, creating a landscape that appears as a patchwork of agricultural fields, pastures, and remnant forest patches. The area is crossed by several small rivers and streams that form part of the Paraguay River basin. These waterways have carved shallow valleys throughout the region, creating natural drainage systems that have influenced local settlement patterns and land use. The Tebicuary-mí River, one of the more significant waterways in the vicinity, has shaped portions of the surrounding landscape through its gradual erosive action. Soil composition in the region tends toward reddish clay-loam mixtures, reflecting the area's subtropical climate and weathering patterns. These soils, while generally fertile, vary in their agricultural potential depending on local drainage conditions and organic content.Optimal Areas for Solar PV Development
Several characteristics of the Coronel Oviedo region make it potentially suitable for large-scale solar photovoltaic installations. The most favorable areas for such development would include: The plains extending to the west and southwest of Coronel Oviedo offer particularly promising conditions for solar development. These areas feature minimal topographical variation, reducing construction complexity and shadow effects that can diminish solar panel efficiency. The relatively flat terrain here would minimize earthwork requirements during installation and reduce overall development costs. Elevated plateaus found within 30 kilometers of the city provide another advantageous setting for solar installations. These higher ground positions typically experience less fog accumulation and can benefit from slightly clearer atmospheric conditions compared to lower-lying areas. The modest elevation gain also reduces the risk of seasonal flooding that could impact infrastructure. Former agricultural lands that have experienced soil degradation represent practical opportunities for solar development without compromising prime agricultural production. Several such areas exist in the northeastern sectors surrounding Coronel Oviedo, where historical intensive farming has reduced agricultural productivity. The region's natural clearings, particularly those with southern exposures and minimal tree cover, would require less vegetation removal and site preparation. These open areas, which are scattered throughout the landscape but more common in the central and western approaches to the city, present reduced environmental impact for development. Areas with proximity to existing transmission infrastructure, particularly along the routes connecting Coronel Oviedo to Ciudad del Este and Asunción, offer logistical advantages for grid connection. The relatively developed road network around Coronel Oviedo also facilitates construction access and ongoing maintenance operations for solar facilities. The generally modest slope angles throughout much of the surrounding territory are well within the optimal range for fixed solar array installation, typically requiring minimal specialized mounting or extensive grading work. This characteristic applies to approximately 70% of the land within a 50-kilometer radius of the city center.Citation Guide
