Daireaux, Buenos Aires, Argentina presents a moderately favorable location for year-round solar energy generation, though with significant seasonal variations typical of its Southern Temperate Zone position. The location experiences substantial differences in solar output throughout the year, ranging from excellent summer performance to modest winter production.
Seasonal Solar Performance
Summer delivers the strongest solar generation at 7.87 kWh per day per kW of installed capacity, making December through February the peak production months. Spring follows as the second-best season with 6.22 kWh per day per kW, offering solid energy output from September through November. Autumn shows declining performance at 4.21 kWh per day per kW during March through May, while winter presents the most challenging period with only 3.10 kWh per day per kW from June through August. For optimal year-round energy capture at this location, solar panels should be installed at a fixed tilt angle of 32 degrees facing north. This angle maximizes total annual production by balancing the sun's varying position throughout the seasons.Environmental and Weather Factors
Several local factors could potentially impact solar energy production in Daireaux and require consideration during installation planning. The Pampas region experiences frequent dust storms and agricultural activities that can coat solar panels with dirt, dust, and organic matter. This accumulation significantly reduces panel efficiency by blocking sunlight from reaching the photovoltaic cells. Regular cleaning schedules and anti-soiling coatings can help maintain optimal performance. Hail storms are common in this agricultural region, particularly during spring and summer months when solar production is at its peak. These weather events can damage panels and mounting systems. Installing panels with tempered glass rated for hail impact and using robust mounting systems helps protect against storm damage. Strong winds associated with Pampas weather patterns can stress mounting systems and potentially damage installations. Proper structural engineering of mounting systems and regular inspections ensure panels remain secure during high-wind events.Preventative Installation Measures
To maximize energy production despite these challenges, several installation strategies prove effective:- Install panels with anti-reflective and hydrophobic coatings that help shed dust and moisture
- Design accessible mounting systems that facilitate regular cleaning and maintenance
- Use reinforced mounting structures engineered for local wind loads and weather conditions
- Select panels with impact-resistant glass and robust frame construction
- Implement monitoring systems to quickly identify performance issues from soiling or damage
Note: The Southern Temperate Zone extends from -35° latitude South down to -66.5° latitude.

Solar output per kW of installed solar PV by season in Daireaux
Seasonal solar PV output for Latitude: -36.5996, Longitude: -61.7475 (Daireaux, Argentina), 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 32° North in Daireaux, Argentina
To maximize your solar PV system's energy output in Daireaux, Argentina (Lat/Long -36.5996, -61.7475) throughout the year, you should tilt your panels at an angle of 32° 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 Daireaux, Argentina
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 Daireaux, Argentina. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 21° North in Summer | 41° North in Autumn | 51° North in Winter | 29° 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 Daireaux, Argentina
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 Daireaux, Argentina.
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 Daireaux, Argentina
Topography Around Daireaux
The landscape surrounding Daireaux in Buenos Aires Province is characterized by the gently rolling plains that define much of Argentina's Pampas region. This area sits within the heart of the fertile grasslands that stretch across central Argentina, featuring predominantly flat to very gently undulating terrain with minimal elevation changes across vast distances. The topography consists of broad, open plains with subtle rises and depressions that create a softly undulating surface rather than dramatic hills or valleys. Elevation changes are typically gradual and measured in meters rather than hundreds of meters, making this one of the most consistently level regions in South America. The landscape is punctuated by shallow creek beds and seasonal waterways that have carved gentle depressions into the terrain over millennia. Agricultural fields dominate the visual landscape, with the natural grasslands having been largely converted to crop production and cattle grazing. The terrain's gentle nature means that field boundaries often extend to the horizon, broken only by occasional farmsteads, windbreaks of planted trees, and rural infrastructure.Optimal Areas for Large-Scale Solar Development
The consistently flat terrain throughout the Daireaux region presents excellent opportunities for large-scale solar photovoltaic installations. The minimal topographical variation means that extensive solar arrays can be constructed with relatively simple ground-mounting systems, avoiding the complications and additional costs associated with sloped or uneven terrain. Areas to the west and southwest of Daireaux township offer particularly favorable conditions for solar development. These zones feature the most consistently level terrain with the fewest natural obstacles such as waterways or existing infrastructure. The agricultural nature of the land means that large contiguous parcels are readily available, which is essential for utility-scale solar projects that require hundreds or thousands of hectares. The slightly elevated areas scattered throughout the region, while still very gentle, provide natural drainage advantages that help prevent water accumulation around solar installations during Argentina's wet season. These marginally higher zones also tend to have fewer seasonal waterways crossing through them, reducing potential complications for large solar arrays. Transportation infrastructure accessibility is another crucial factor that favors certain areas around Daireaux. Zones within reasonable proximity to existing roads and electrical transmission lines offer significant advantages for solar development, as the flat terrain makes it relatively straightforward to construct access roads and electrical connections to proposed solar sites. The absence of significant vegetation or forested areas throughout most of the region means that land clearing requirements are minimal, though developers would need to consider the displacement of existing agricultural activities. The open nature of the landscape also ensures that shading from natural features is not a concern for solar panel positioning and spacing.Argentina solar PV Stats as a country
Argentina ranks 43rd in the world for cumulative solar PV capacity, with 1,071 total MW's of solar PV installed. This means that 1.50% of Argentina's total energy as a country comes from solar PV (that's 35th in the world). Each year Argentina is generating 24 Watts from solar PV per capita (Argentina ranks 63rd in the world for solar PV Watts generated per capita). [source]
