San Pedro de Jujuy, Argentina is a reasonably good location for year-round solar energy generation, though it shows some seasonal variation typical of its Southern Sub Tropical climate zone.

Seasonal Solar Performance

The solar energy output at this location varies significantly throughout the year. Summer provides the highest energy production at 6.41 kWh per day per kW of installed solar capacity, making it the peak season for solar generation. Spring follows closely with 6.11 kWh per day per kW, representing the second-best period for solar energy harvest. Both autumn and winter show identical but reduced output at 4.51 kWh per day per kW of installed capacity. This represents about a 30% decrease compared to summer production, which is relatively moderate for a location at this latitude. The annual average works out to approximately 5.4 kWh per day per kW, which places San Pedro de Jujuy in the category of locations with good solar potential, though not exceptional compared to some desert regions.

Optimal Panel Installation

For maximum year-round energy production at San Pedro de Jujuy, solar panels should be installed at a fixed tilt angle of 22 degrees facing North. This angle has been calculated to optimize total annual solar output by accounting for the sun's varying position throughout the year and weighting for the actual solar energy potential at different times.

Local Environmental Factors

Several environmental and weather factors in the San Pedro de Jujuy region could potentially impact solar energy production:

• Dust and particulate matter: The region's proximity to mountainous terrain and semi-arid conditions can lead to dust accumulation on solar panels, reducing their efficiency over time
• Seasonal rainfall patterns: While rain can help clean panels naturally, extended wet periods during certain seasons may reduce solar irradiance
• High altitude effects: The location's elevation may result in more intense UV radiation but also potentially more variable weather conditions
• Temperature extremes: High summer temperatures can reduce panel efficiency, while the significant seasonal variation may cause thermal stress on equipment

Preventative Measures for Optimal Performance

To maximize solar energy production at this location, several preventative measures should be considered during installation and maintenance: Regular cleaning schedules are essential, particularly during dry seasons when dust accumulation is highest. Installing panels with adequate spacing allows for proper airflow, helping to keep operating temperatures lower during hot summer months when production is at its peak. Choosing high-quality mounting systems that can handle thermal expansion and contraction will help ensure long-term reliability given the seasonal temperature variations. Additionally, selecting solar panels and inverters rated for the local temperature ranges will maintain efficiency across all seasons. Implementing a monitoring system can help identify when cleaning or maintenance is needed, ensuring the system continues to operate at optimal capacity throughout the year. Given that summer and spring offer the best production periods, ensuring peak system performance during these seasons is particularly important for maximizing annual energy yield.

Solar output per kW of installed solar PV by season in San Pedro De Jujuy

Seasonal solar PV output for Latitude: -24.2318, Longitude: -64.8678 (San Pedro De Jujuy, 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 22° North in San Pedro De Jujuy, Argentina

To maximize your solar PV system's energy output in San Pedro De Jujuy, Argentina (Lat/Long -24.2318, -64.8678) throughout the year, you should tilt your panels at an angle of 22° 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 San Pedro De Jujuy, 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 San Pedro De Jujuy, Argentina. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 22° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
8° North in Summer	30° North in Autumn	39° North in Winter	18° 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

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 San Pedro De Jujuy, Argentina

Topographical Features of San Pedro de Jujuy

San Pedro de Jujuy sits in the northwestern region of Argentina within the province of Jujuy, positioned at an elevation of approximately 550 meters above sea level. The city occupies a strategic location in the Río Grande de Jujuy valley, where the landscape is characterized by a transitional zone between the eastern foothills of the Andes Mountains and the beginning of the Chaco plains that extend eastward toward Paraguay and Brazil. The immediate terrain around San Pedro de Jujuy features rolling hills and gentle slopes that gradually rise toward the west, where the pre-Andean mountain ranges begin to assert their presence. The eastern approaches to the city are notably flatter, representing the edge of the vast lowland plains that dominate much of northern Argentina. This topographical diversity creates a landscape of moderate relief with valleys carved by seasonal watercourses and permanent rivers that flow generally from west to east. The region experiences a semi-arid to subtropical climate, with the surrounding hills covered in sparse vegetation typical of the transition between mountain foothills and lowland savanna. The soil composition varies from alluvial deposits in the valley floors to more rocky and sandy compositions on the elevated terrain, reflecting the geological processes that have shaped this area over millennia.

Optimal Areas for Large-Scale Solar Development

The most promising locations for extensive solar photovoltaic installations lie to the east and southeast of San Pedro de Jujuy, where the terrain becomes increasingly flat as it approaches the Chaco plains. These areas offer several advantages for solar development, including minimal topographical obstacles that would require expensive grading or terracing work. The gentle eastward slope of much of this terrain provides natural drainage while maintaining relatively consistent solar exposure throughout the day. Areas located between 10 and 30 kilometers southeast of the city present particularly favorable conditions, as they combine flat to gently rolling topography with sufficient distance from urban development to allow for large-scale installations. The soil composition in these zones tends to be stable enough to support solar mounting systems while remaining economical to develop compared to more mountainous alternatives. The valley floors and broad terraces that extend eastward from San Pedro de Jujuy also represent excellent opportunities for solar development. These areas benefit from centuries of sediment deposition that has created level surfaces with good load-bearing capacity. The relatively sparse vegetation in these semi-arid zones reduces environmental concerns and clearing costs that might be associated with solar installations in more densely forested regions. Northern and northeastern areas around the city offer additional potential, particularly where the landscape opens up into broader valleys and plains. These locations typically feature consistent topography over large areas, which simplifies the engineering and construction processes for major solar installations. The absence of significant elevation changes across these zones means that shading between solar panel arrays can be minimized through standard spacing techniques.
