Solar PV Analysis of Buenos Aires, Argentina
Buenos Aires, Argentina, is a suitable location for solar PV generation throughout the year. During the summer season, an average of 7.79 kWh per day per kW of installed solar can be generated; in autumn, this figure is 4.58 kWh/day; in winter, it's 3.27 kWh/day; and in spring, it reaches 6.29 kWh/day per kW of installed solar capacity. The higher energy production during summer months can be attributed to longer daylight hours and increased temperatures that enable more efficient conversion of sunlight into electricity compared to other seasons. Moreover, there are generally fewer cloudy days during the summer months which further enhances the amount of available sunlight for power generation.
Nonetheless, certain weather conditions may pose challenges for solar PV generation in Buenos Aires. Heavy rain or prolonged periods of cloud cover could limit the amount of sunlight accessible for power generation on those days and subsequently decrease overall energy production from a given system over time.
To optimize energy production at this location, fixed panel installations should ideally be tilted at an angle of 30 degrees North to maximize exposure to sunlight throughout the year. While environmental factors such as topography and local weather patterns may impact solar production to some extent, taking preventative measures like proper installation techniques and regular maintenance can help ensure greater energy output from your solar panels despite these potential obstacles.
Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 519 locations across Argentina. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Buenos Aires
Seasonal solar PV output for Latitude: -34.6142, Longitude: -58.3811 (Buenos Aires, 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 Buenos Aires, Argentina
To maximize your solar PV system's energy output in Buenos Aires, Argentina (Lat/Long -34.6142, -58.3811) 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 Buenos Aires, 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 Buenos Aires, 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 Buenos Aires, 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 Buenos Aires, 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 Buenos Aires, Argentina
The topography around Buenos Aires, Argentina is mostly flat and low-lying with some rolling hills in the surrounding area. The highest point near the city is Cerro de los Remedios at a height of about 730 meters (2,400 feet). Areas to the west and south of Buenos Aires are more hilly and mountainous.
The most suitable areas for large-scale solar PV installations would be those that have unobstructed access to direct sunlight throughout the year. Areas with flat terrain such as open fields or rooftops would be ideal for this purpose. The western and southern suburbs of Buenos Aires tend to receive more hours of sunshine than other parts of the city, making them prime locations for solar energy projects. Additionally, sites located close to existing power lines may also be advantageous since they would reduce transmission losses associated with long distance electricity transfer.
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.
