Tupungato, Mendoza, Argentina presents a moderately favorable location for year-round solar PV energy generation, though with significant seasonal variations typical of its Southern Sub Tropics climate zone.
Seasonal Solar Performance
The solar energy output at this location shows strong seasonal patterns. Summer delivers the highest production at 8.07 kWh per day per kW of installed capacity, making it the peak generation period. Spring follows as the second-best season with 7.17 kWh per day per kW, offering excellent solar conditions as well. Autumn sees a notable drop to 4.86 kWh per day per kW, while winter represents the challenging period with only 3.32 kWh per day per kW of production. This winter output is quite low and would require careful system sizing to meet energy needs during these months.Optimal Installation Configuration
For fixed panel installations at this Tupungato location, the ideal tilt angle is 29 degrees facing North to maximize total year-round solar production. This angle is calculated by analyzing daily solar elevation angles, optimal panel positioning, and weighting these factors using solar irradiance data that accounts for Earth's elliptical orbit.Environmental and Weather Challenges
Several local factors could potentially impact solar production at this location:- High altitude dust and wind: Tupungato sits in a mountainous region where dust accumulation on panels can significantly reduce efficiency
- Hail risk: The area experiences occasional severe weather that could damage solar installations
- Temperature extremes: Both hot summers and cold winters can affect panel efficiency and system components
- Snow coverage: Winter snow accumulation could temporarily block panels
Preventative Measures for Better Performance
To maximize energy production despite these challenges, several installation strategies are recommended: Regular cleaning systems or accessible panel positioning should be incorporated to address dust accumulation. Installing panels with appropriate spacing allows for natural wind cleaning and prevents snow buildup between rows. Hail-resistant tempered glass and robust mounting systems provide protection against severe weather. Quality inverters and electrical components rated for the local temperature range ensure reliable operation year-round. Proper panel spacing and mounting height facilitate snow shedding during winter months. Additionally, installing a slightly steeper tilt angle than the calculated optimum may help with both snow removal and dust management, though this should be balanced against the slight reduction in annual energy yield.Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.

Solar output per kW of installed solar PV by season in Tupungato
Seasonal solar PV output for Latitude: -33.3704, Longitude: -69.1319 (Tupungato, 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 29° North in Tupungato, Argentina
To maximize your solar PV system's energy output in Tupungato, Argentina (Lat/Long -33.3704, -69.1319) throughout the year, you should tilt your panels at an angle of 29° 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 Tupungato, 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 Tupungato, Argentina. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 29° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 17° North in Summer | 38° North in Autumn | 49° North in Winter | 26° 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.

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 Tupungato, Argentina
Topographical Features Around Tupungato
Tupungato sits in a dramatically varied landscape within the Mendoza Province of Argentina, positioned at the eastern edge of the Andes mountain range. The area is characterized by significant elevation changes, with the terrain rising sharply to the west toward the towering Tupungato volcano, which reaches over 6,500 meters above sea level. This imposing peak dominates the western horizon and creates a striking backdrop for the entire region.
Moving eastward from the mountainous terrain, the landscape gradually transitions into the Mendoza River valley and eventually into the broader Cuyo region's piedmont plains. The immediate vicinity around Tupungato features rolling hills and elevated plateaus that descend from the Andean foothills, creating a series of natural terraces and gentle slopes. These intermediate elevations, typically ranging from 1,000 to 2,000 meters above sea level, provide a buffer zone between the steep mountain faces and the flatter valley floors.
The region's topography is heavily influenced by ancient glacial activity and ongoing geological processes associated with the active Andean uplift. This has resulted in a landscape punctuated by ridges, valleys, and relatively flat mesa-like formations. The area experiences significant drainage patterns flowing eastward toward the Atlantic, with several seasonal watercourses carving channels through the terrain during snowmelt periods.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations lie in the eastern sections of the region, where the terrain begins to level out into the broader Mendoza valley system. These areas offer the ideal combination of relatively flat topography, stable geological conditions, and reduced elevation compared to the mountainous western zones. The piedmont plains extending eastward from Tupungato provide expansive areas of gently rolling terrain that would require minimal grading for large-scale solar arrays.
The elevated plateaus and mesa formations scattered throughout the middle elevations also present excellent opportunities for solar development. These naturally flat or gently sloping surfaces often span considerable areas and provide stable foundations for photovoltaic installations. Their elevated position offers additional advantages in terms of reduced atmospheric interference and improved air circulation for cooling solar panels.
Areas to the northeast and southeast of Tupungato are particularly promising, as they combine favorable topographical conditions with proximity to existing infrastructure. The terrain in these directions features broad, open spaces with minimal vegetation and relatively uniform slopes that face optimal directions for solar collection. These locations also benefit from being situated away from the immediate influence of the high Andean peaks, which can create localized weather patterns and shading effects.
The valley floors and alluvial fans extending eastward from the mountain base provide additional suitable terrain for solar installations. While some of these areas may be utilized for agriculture, many sections remain undeveloped and offer the flat, stable surfaces ideal for large-scale solar arrays. The key advantage of these locations is their accessibility and the potential for easier connection to electrical grid infrastructure that typically follows valley transportation corridors.
