Solar Energy Potential in Santa Anita, Entre Rios, Argentina
Santa Anita, Entre Rios, Argentina, located in the Southern Sub Tropics at coordinates -32.1627, -58.7837, offers varying potential for solar energy generation throughout the year. This location experiences significant seasonal fluctuations in solar energy production that are worth understanding for anyone considering solar PV installation. The energy output from solar panels in Santa Anita follows a predictable seasonal pattern. Summer delivers the highest production at 7.95kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 6.61kWh/day. Energy generation drops considerably during autumn (4.48kWh/day) and reaches its lowest point in winter (3.52kWh/day).Seasonal Variations and Installation Considerations
The substantial difference between summer and winter production (more than double) indicates that Santa Anita has a pronounced seasonal cycle. This means that supplementary energy sources might be necessary during the winter months if consistent energy output is required year-round. For fixed panel installations at this location, the ideal tilt angle to maximize total year-round solar production is 28 degrees facing North. This specific angle optimizes the annual energy harvest by balancing seasonal variations in the sun's position.Environmental and Weather Factors
Several environmental factors could potentially impact solar production in Santa Anita:- Dust and pollen accumulation on panels, particularly during dry seasons, can reduce efficiency by up to 10%
- Occasional summer thunderstorms and hail in this subtropical region pose risks to panel integrity
- Morning fog or mist common in river valleys of this region can delay peak production hours
- Regular cleaning schedules, particularly before and after dry seasons
- Hail-resistant panel selection with appropriate certification
- Elevated mounting systems to reduce dust accumulation and improve air circulation
- Weather-sealed junction boxes and connectors rated for subtropical conditions
Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.

Ideally tilt fixed solar panels 28° North in Santa Anita, Argentina
To maximize your solar PV system's energy output in Santa Anita, Argentina (Lat/Long -32.1627, -58.7837) throughout the year, you should tilt your panels at an angle of 28° 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 Santa Anita, 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 Santa Anita, Argentina. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 28° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 16° North in Summer | 38° North in Autumn | 47° North in Winter | 25° 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 Santa Anita, 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 Santa Anita, 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 Santa Anita, Argentina
Santa Anita is located in the Entre Ríos province of Argentina, positioned in the eastern part of the country near the Uruguay border. The topography of this region is characterized by gently rolling plains that form part of the larger Mesopotamia region of Argentina. This area sits between the Paraná and Uruguay Rivers, creating a landscape of fertile lowlands with modest elevation changes. The terrain around Santa Anita features undulating hills with gradual slopes rather than steep mountains or dramatic valleys. The elevation typically ranges between 30 and 70 meters above sea level, with minimal sharp variations. This gentle topography is part of the Pampas ecosystem that extends across much of eastern Argentina, though the Entre Ríos region has more relief and water features than the flatter pampas to the south and west.
Hydrological Features
The area is marked by numerous small streams and tributaries that eventually feed into the larger Uruguay River to the east. These waterways have carved shallow valleys through the landscape over time, creating natural drainage systems. The proximity to the Uruguay River influences the overall topography, with land generally sloping gently toward this major waterway. Wetlands and small lagoons dot the landscape, particularly in low-lying areas where water naturally collects during rainy periods. These hydrological features create minor variations in the otherwise gentle topography.Soil and Surface Characteristics
The soils around Santa Anita are predominantly loamy and clay-rich, reflecting the region's geological history as part of a vast sedimentary basin. These soils support extensive agriculture, which has modified the natural landscape significantly. The natural vegetation would have been a mix of grasslands and scattered woodland, though much has been converted to agricultural use.Optimal Areas for Solar PV Development
For large-scale solar photovoltaic development, the most suitable areas near Santa Anita would be the higher elevation plains that feature minimal flooding risk and good drainage. Specifically, the gently sloping areas to the west and northwest of Santa Anita offer favorable conditions with: Relatively flat terrain that requires minimal grading for installation of solar arrays Good drainage characteristics that reduce the risk of waterlogging Limited shadowing from topographical features Reduced flood risk compared to areas closer to the Uruguay River and its tributaries The elevated plateaus between stream valleys provide ideal locations, as they offer stable ground conditions and avoid the more flood-prone riparian zones. These higher grounds typically have fewer trees and obstacles that might cast shadows on solar panels. Areas to avoid would include the low-lying wetlands and stream valleys that experience seasonal flooding, as well as any locations with dense tree cover or significant morning/afternoon shadowing from even modest hills. The northwestern sector extending toward Villaguay and the southwestern areas toward Basavilbaso represent particularly promising zones for solar development, as they combine favorable topography with good access to existing transportation infrastructure that could facilitate construction and maintenance of solar facilities.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]
Are there incentives for businesses to install solar in Argentina?
Yes, there are several incentives for businesses wanting to install solar energy in Argentina. The government offers a range of tax credits and subsidies for businesses that invest in renewable energy projects. Additionally, the country has implemented a net metering system which allows businesses to sell excess electricity generated from their solar installations back to the grid at a premium rate. Finally, the government also provides access to low-interest loans and grants for businesses looking to invest in solar energy projects.
