Loma Plata, Boquerón Department, Paraguay presents a moderately favorable location for year-round solar energy generation, though with notable seasonal variations that reflect the region's tropical climate patterns.
Seasonal Solar Performance
The solar energy output at this location shows significant seasonal fluctuations. Summer delivers the highest production at 7.15 kWh per day per kW of installed capacity, making it the peak season for solar generation. Spring follows as the second-best performing season with 6.07 kWh per day per kW, while autumn drops to 5.21 kWh per day per kW. Winter presents the most challenging period for solar production, generating only 4.01 kWh per day per kW of installed capacity. This seasonal pattern aligns well with the tropical wet and dry season cycle typical of this latitude. The higher summer and spring outputs coincide with the region's dry season when cloud cover is typically reduced and solar irradiance is at its strongest.Optimal Panel Configuration
For maximum year-round energy production at Loma Plata, Boquerón Department, solar panels should be installed at a fixed tilt angle of 20 degrees facing north. This specific angle has been calculated to optimize total annual solar output by accounting for the sun's varying elevation throughout the year and weighting these angles according to the actual solar irradiance potential at this location.Environmental and Weather Challenges
Several local factors could potentially impact solar energy production at this location:- Seasonal cloud cover: The tropical wet season brings increased cloud formation and precipitation, significantly reducing solar irradiance during winter months
- High humidity: The tropical climate creates consistently high humidity levels that can affect panel efficiency and promote corrosion
- Dust accumulation: The dry season may bring increased dust and particulate matter that can coat panel surfaces
- Intense UV exposure: The tropical location subjects equipment to high levels of ultraviolet radiation year-round
Preventative Measures for Optimal Performance
To maximize solar energy production despite these challenges, several installation strategies should be considered:- Regular cleaning schedules: Implement frequent panel washing, especially during dry seasons when dust accumulation peaks
- Corrosion-resistant materials: Use marine-grade aluminum frames and stainless steel mounting hardware to withstand high humidity
- Adequate ventilation: Install panels with sufficient air gaps beneath to promote cooling and reduce humidity-related efficiency losses
- UV-resistant components: Select cables, junction boxes, and mounting materials specifically rated for high UV environments
- Drainage considerations: Ensure proper water runoff during wet season storms to prevent standing water around electrical components
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 20° North in Loma Plata, Paraguay
To maximize your solar PV system's energy output in Loma Plata, Paraguay (Lat/Long -22.3829, -59.8355) throughout the year, you should tilt your panels at an angle of 20° 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 Loma Plata, 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 Loma Plata, Paraguay. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 20° 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 | 16° 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.

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 Loma Plata, 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 Loma Plata, Paraguay
Topographical Characteristics of Loma Plata Region
The area surrounding Loma Plata in Paraguay sits within the heart of the Gran Chaco, one of South America's largest lowland plains. This expansive region is characterized by remarkably flat terrain with minimal elevation changes across vast distances. The landscape consists primarily of gently undulating plains that stretch endlessly toward the horizon, broken only by occasional low ridges and subtle depressions that channel seasonal water flow. The elevation around Loma Plata remains relatively consistent, hovering around 400 to 450 meters above sea level. The terrain exhibits a gradual slope from northwest to southeast, though this gradient is so gentle that it becomes barely perceptible to the naked eye. Small variations in elevation, typically ranging only 10 to 30 meters across several kilometers, create subtle changes in drainage patterns and vegetation density.Soil and Surface Conditions
The surface composition varies between sandy loams and clay-rich soils, with patches of saline deposits scattered throughout the region. During dry seasons, much of the ground becomes firm and stable, while the wet season can transform lower-lying areas into temporary wetlands or muddy expanses. The soil structure generally provides good drainage in elevated areas, though some locations experience seasonal waterlogging. Natural vegetation consists mainly of dry forest, scrubland, and grassland patches. The tree cover is typically sparse to moderate, with most forested areas concentrated along seasonal watercourses or in slightly elevated zones where moisture retention is better. Palm groves dot the landscape in certain areas, creating distinctive landmarks in an otherwise uniform environment.Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations lie on the slightly elevated sandy ridges and plateaus scattered throughout the region. These areas offer several advantages including stable, well-draining soils that remain firm year-round, minimal flooding risk during wet seasons, and relatively sparse vegetation that would require less clearing. Areas located 15 to 30 kilometers northeast and southwest of Loma Plata present particularly favorable conditions. These zones feature the flattest terrain with the most consistent elevation, reducing construction and maintenance complexities. The soil composition in these areas tends toward sandy loam, providing excellent drainage while maintaining sufficient stability for large infrastructure projects. The region's expansive open spaces allow for massive solar arrays with minimal topographical constraints. Unlike mountainous or heavily forested regions, the Chaco's flat terrain eliminates concerns about shading from hills or the need for extensive land grading. The consistent elevation also means that solar panels can be installed in uniform configurations across large areas without requiring significant adjustments for slope variations.Infrastructure Considerations
Transportation access represents a key factor in site selection, as the region's remote location requires careful consideration of existing road networks. Areas closer to established transportation corridors, particularly those with access to all-weather roads, would prove more practical for construction and ongoing maintenance operations. The absence of significant waterways or wetlands in the elevated areas eliminates many environmental constraints that might complicate development elsewhere. However, the seasonal nature of precipitation means that any large-scale development must account for dramatic differences between wet and dry season conditions, particularly regarding site access and soil stability.Citation Guide
