Solar PV Analysis of Pilar, Argentina
Pilar, Buenos Aires, Argentina (latitude: -34.4662, longitude: -58.9791) is a suitable location for generating solar power due to its position within the Southern Subtropics region. The average daily energy production per kW of installed solar capacity varies by season: 7.79 kWh in summer, 4.58 kWh in autumn, 3.27 kWh in winter, and 6.29 kWh in spring. This indicates that summer and spring are the most productive seasons for solar power generation at this location.
To maximize efficiency of fixed-panel installations at this site, it is recommended to tilt the panels at an angle of 30 degrees facing North. This orientation will optimize energy production throughout the year.
While Pilar's overall suitability for solar power generation is good, certain local factors could potentially affect energy production levels on occasion—such as heavy winds or hailstorms—which can damage panels or obstruct sunlight reaching them during these events.
To mitigate potential impacts from these environmental challenges during installation and operation of a solar system in Pilar:
1) Ensure that panels are securely mounted to withstand strong winds.
2) Utilize high-quality materials with proven durability against harsh weather conditions.
3) Regularly inspect and maintain your system to identify any potential issues early on and address them promptly.
4) Consider incorporating protective measures such as hail guards if deemed necessary based on local climate patterns.
By taking these precautions into account when installing a solar system in Pilar, Buenos Aires, Argentina's unique environment can be effectively managed to ensure optimal energy production year-round while minimizing risks associated with adverse weather conditions or other local factors impacting performance
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 Pilar
Seasonal solar PV output for Latitude: -34.4662, Longitude: -58.9791 (Pilar, 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 Pilar, Argentina
To maximize your solar PV system's energy output in Pilar, Argentina (Lat/Long -34.4662, -58.9791) 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 Pilar, 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 Pilar, 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 Pilar, 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 Pilar, 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 Pilar, Argentina
The topography around Pilar, Argentina is generally flat with some rolling hills. Areas that are most suitable for large-scale solar PV installations would be on the flat plains and open areas of land with no trees or other obstructions blocking direct sunlight. Nearby areas such as the Paraná Delta, San Fernando, and Zárate are all good options for large solar PV installations due to their mostly flat terrain and lack of obstructions.
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.
