Berazategui, Argentina, situated in the southern suburbs of Buenos Aires, presents a mixed picture for solar energy generation. This location in the Southern Sub Tropics experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems throughout the year.

Seasonal Solar Performance

The solar energy potential in Berazategui fluctuates considerably across seasons. Summer months yield the highest output at 7.79 kWh per day for each kilowatt of installed solar capacity. This drops dramatically in winter to just 3.27 kWh per day. Spring and autumn offer moderate production levels of 6.29 kWh and 4.58 kWh per day, respectively. These figures indicate that solar energy generation is most effective during the warmer months, particularly from late spring through early autumn. During this period, longer daylight hours and more direct sunlight contribute to higher energy yields. However, the significant drop in winter production suggests that supplementary energy sources may be necessary during colder months.

Optimal Panel Installation

For fixed panel installations in Berazategui, the ideal tilt angle to maximize year-round solar production is 30 degrees facing North. This angle is calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the location's latitude and the Earth's elliptical orbit.

Environmental Considerations

While Berazategui doesn't face extreme environmental challenges for solar production, there are some factors to consider: 1. Air pollution: Being close to Buenos Aires, urban air pollution could slightly reduce solar panel efficiency. 2. Humidity: The region's humidity might lead to increased dust accumulation on panels. To mitigate these issues, regular cleaning of solar panels is recommended. Additionally, installing panels at a slight angle (as suggested above) can help with natural cleaning during rainfall. Using high-quality, dust-resistant panels can also improve performance in these conditions. In conclusion, while Berazategui is not an ideal location for year-round solar energy production due to significant seasonal variations, it still offers good potential, especially during warmer months. Proper installation techniques and maintenance can help maximize energy output throughout the year.

Solar output per kW of installed solar PV by season in Berazategui

Seasonal solar PV output for Latitude: -34.7395, Longitude: -58.2573 (Berazategui, 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 30° North in Berazategui, Argentina

To maximize your solar PV system's energy output in Berazategui, Argentina (Lat/Long -34.7395, -58.2573) throughout the year, you should tilt your panels at an angle of 30° 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 Berazategui, 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 Berazategui, Argentina. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 30° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
18° North in Summer	40° North in Autumn	49° North in Winter	27° 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 Berazategui, 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 Berazategui, Argentina.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Berazategui, Argentina

The topography around Berazategui, Argentina, is generally characterized by flat to gently rolling terrain. This area is part of the vast Pampas region, which is known for its expansive grasslands and low-lying plains. The landscape is predominantly flat, with very few significant elevations or depressions.

Berazategui is located near the eastern edge of the Pampas, close to the Río de la Plata estuary. As you move inland from the river, the terrain remains relatively level, with only slight variations in elevation. This flat topography is a result of centuries of sediment deposition from rivers and wind-blown loess, creating a fertile and even landscape.

The area's proximity to the Río de la Plata means that some parts closer to the water may be more prone to flooding or have slightly lower elevations. However, most of the surrounding region maintains a consistent, low-lying profile without any major hills or valleys.

Suitable Areas 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 flat terrain of the Pampas region around Berazategui offers numerous advantages for solar energy development:

1. Open spaces: The vast, open grasslands provide ample room for extensive solar arrays without the need for significant land clearing or preparation.

2. Minimal shading: The lack of hills or tall natural features means there are fewer obstacles that could cast shadows on solar panels, maximizing their exposure to sunlight throughout the day.

3. Ease of construction: The level ground simplifies the installation process and reduces construction costs associated with terrain modification.

4. Accessibility: The flat landscape allows for easier transportation of equipment and materials to the installation sites.

The most suitable areas for large-scale solar PV would likely be found slightly inland from Berazategui, away from the more densely populated coastal areas and potential flood zones near the Río de la Plata. Rural areas to the south and southwest of Berazategui, where there is less urban development and more open land, could be ideal locations for solar farms.

It's important to note that while the topography is favorable, other factors such as local climate conditions, grid connectivity, and land use regulations would also need to be considered when determining the best locations for large-scale solar PV installations in this region.
