Solar Energy Potential in Filadelfia, Boquerón Department, Paraguay
Filadelfia, Boquerón Department, Paraguay, located at latitude -22.3467 and longitude -60.034, offers generally favorable conditions for solar PV energy production throughout the year. This tropical location benefits from relatively consistent sunlight patterns, though with notable seasonal variations in energy output. The solar energy generation potential shows significant fluctuation across the meteorological seasons. During summer, panels can produce an impressive 7.16kWh per day for each kilowatt of installed capacity. This drops to 5.02kWh/day in autumn, reaches its lowest point in winter at 3.99kWh/day, and recovers substantially in spring to 6.01kWh/day. For fixed solar panel installations in Filadelfia, Boquerón Department, the ideal tilt angle to maximize year-round energy production is 19 degrees facing North. This specific angle has been calculated to optimize solar capture throughout the year, taking into account the site's southern hemisphere location and seasonal sun path variations.Seasonal Considerations
The summer months clearly represent peak production time in Filadelfia, Boquerón Department, with almost 80% higher daily output compared to winter. Spring also offers excellent generation potential, making these two seasons particularly advantageous for solar energy production. The significant drop during winter months indicates that supplementary power sources might be beneficial for consistent year-round energy supply, especially for off-grid installations.Environmental and Weather Factors
Several environmental factors could potentially impact solar production in Filadelfia:- Dust accumulation: The region's semi-arid climate can lead to dust buildup on panels, reducing efficiency. Regular cleaning maintenance is essential.
- Seasonal storms: During the wet season, thunderstorms can temporarily reduce output and potentially damage equipment if not properly secured.
- High temperatures: Summer temperatures in the Chaco region can exceed 40°C, which may reduce panel efficiency. Installing panels with adequate airflow underneath can help mitigate this issue.
- Potential for flooding: In low-lying areas during the wet season, ground-mounted systems should be elevated sufficiently.
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 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 19° North in Filadelfia, Paraguay
To maximize your solar PV system's energy output in Filadelfia, Paraguay (Lat/Long -22.3467, -60.034) throughout the year, you should tilt your panels at an angle of 19° 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 Filadelfia, 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 Filadelfia, Paraguay. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 19° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 6° North in Summer | 28° North in Autumn | 38° North in Winter | 15° 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 Filadelfia, 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 Filadelfia, 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 Filadelfia, Paraguay
The region surrounding Filadelfia, Paraguay, presents a distinctive topographical profile characterized predominantly by flat to gently undulating terrain. Situated in the heart of the Gran Chaco, this area forms part of the vast lowland plain that extends across western Paraguay. The elevation around Filadelfia averages approximately 150 meters above sea level, with minimal variation across the immediate vicinity.
The Chaco Landscape
The Chaco region where Filadelfia is located features a mixture of savanna, thorny scrubland, and dry forest ecosystems. The terrain is remarkably level, having been formed through centuries of sediment deposition from ancient river systems. This flatness is occasionally interrupted by subtle depressions that may collect water seasonally or low ridges that rise just a few meters above the surrounding plain. Soil composition in the area tends toward sandy and clay-like substrates, with certain sections exhibiting salt deposits—evidence of the region's complex hydrological history. The natural drainage pattern is generally poor, resulting in seasonal waterlogging in some lower-lying areas during the rainy season, while the higher ground remains relatively dry throughout the year.Optimal Areas for Solar Development
For large-scale solar photovoltaic installations, the most suitable locations near Filadelfia would be the elevated sections of the Chaco plain that maintain good drainage characteristics. These areas typically extend to the east and southeast of Filadelfia, where slightly higher terrain provides protection from occasional flooding while maintaining the excellent solar exposure characteristic of the region. The northern and western sectors beyond Filadelfia offer extensive tracts of open land with minimal topographical barriers to solar radiation. These zones, characterized by sparse vegetation and limited agricultural development, present minimal shading concerns and ample space for substantial solar arrays. Areas approximately 15-20 kilometers south of Filadelfia also merit consideration, as they feature expansive cleared sections with favorable ground stability and accessibility via existing transportation routes. These locations combine the advantages of flat terrain with sufficient elevation to avoid seasonal water accumulation.Topographical Considerations
When evaluating specific sites for solar development, several topographical factors warrant attention. The subtle variations in elevation throughout the region, though modest, can significantly impact construction costs and long-term facility performance. Sites with gradual slopes of 1-3% facing northward offer optimal orientation for solar collection in this Southern Hemisphere location. The occasional dry riverbeds (known locally as "riachos") that cross the Chaco landscape should generally be avoided, as these may become active waterways during intense precipitation events. Similarly, the lowest-lying depressions that form seasonal wetlands present challenges for infrastructure development and maintenance. The relatively unobstructed horizon in most directions around Filadelfia minimizes topographical shading concerns that might otherwise reduce energy generation potential. This characteristic, combined with the region's latitude and climate patterns, creates favorable conditions for solar energy harvesting across much of the surrounding territory.Citation Guide
