Luque, Central Department, Paraguay, situated in the Southern Sub Tropics, presents a promising location for solar energy generation. This city experiences varying levels of solar potential throughout the year, with notable fluctuations across seasons.
Seasonal Solar Performance
Summer stands out as the most productive season, with an impressive daily output of 7.59 kWh per kW of installed solar capacity. Spring follows as the second-best season, yielding 5.97 kWh/day. Autumn sees a slight decrease to 5.17 kWh/day, while winter experiences the lowest output at 3.81 kWh/day.
These figures indicate that Luque enjoys favorable conditions for solar energy production, particularly from late spring through early autumn. The substantial difference between summer and winter outputs suggests that energy storage solutions or grid integration might be beneficial to balance seasonal variations.
Optimal Panel Positioning
For fixed panel installations in Luque, Central Department, the ideal tilt angle to maximize year-round solar production is 22 degrees facing North. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the city's latitude and the Earth's elliptical orbit.
Environmental Considerations
While Luque's climate is generally favorable for solar energy, there are a few environmental factors to consider:
- Occasional heavy rainfall, particularly during the summer months, could temporarily reduce solar output.
- Dust accumulation on panels, especially during drier periods, may impact efficiency.
To mitigate these issues, installing panels at the recommended angle helps with natural cleaning during rainfall. Regular maintenance and cleaning schedules should be implemented to ensure optimal performance. Additionally, using high-quality, weather-resistant panels can help maintain efficiency in varying conditions.
Overall, Luque's location offers a good balance of solar potential throughout the year, making it a suitable site for solar PV installations with proper planning and maintenance.
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.

Solar output per kW of installed solar PV by season in Luque
Seasonal solar PV output for Latitude: -25.2682, Longitude: -57.4863 (Luque, Paraguay), 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 22° North in Luque, Paraguay
To maximize your solar PV system's energy output in Luque, Paraguay (Lat/Long -25.2682, -57.4863) 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 Luque, 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 Luque, 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 | 40° 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 Luque, 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 Luque, 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 Luque, Paraguay
The topography around Luque, Paraguay, is characterized by gently rolling plains and low hills, typical of the eastern region of the country. This area is part of the vast Paraguayan Chaco, a mostly flat and low-lying region that extends across much of Paraguay. The landscape is predominantly composed of grasslands and scattered patches of forest, with some wetland areas in lower-lying parts. Luque itself is situated at an elevation of approximately 120 meters (394 feet) above sea level. The terrain gradually slopes downward towards the Paraguay River to the west, while to the east, it rises slightly into more hilly terrain. The area experiences a subtropical climate with hot summers and mild winters, which contributes to the overall vegetation patterns and land use in the region.
Potential for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The relatively flat terrain surrounding Luque offers numerous potential sites for solar farms. The areas to the east and northeast of Luque, where the land becomes slightly more elevated and open, could be particularly well-suited for solar PV development. These higher areas typically receive more direct sunlight throughout the day and are less prone to shading from nearby vegetation or geographical features. Additionally, the slightly elevated terrain may experience fewer issues with flooding or waterlogging, which can be concerns in some of the lower-lying areas closer to the Paraguay River. The expansive grasslands in the region provide ample space for large-scale solar installations without the need for extensive land clearing. However, it's important to note that any potential solar development would need to consider environmental impacts, land ownership, and proximity to existing electrical infrastructure. Areas to the south and southeast of Luque, towards the outskirts of the Greater Asunción metropolitan area, might also offer good potential for solar PV. These locations could benefit from being closer to major population centers and existing power distribution networks, potentially reducing the costs associated with transmitting the generated electricity over long distances. In conclusion, while much of the area around Luque could potentially support solar PV installations, the slightly elevated, open areas to the east and northeast, as well as the outskirts of the metropolitan area to the south and southeast, may offer the most promising locations for large-scale solar energy development.Citation Guide
