Solar Energy Potential in Chimbas, San Juan, Argentina
Chimbas, San Juan, Argentina, located in the Southern Sub Tropics, offers a promising location for solar PV energy generation throughout the year. The seasonal electricity output shows significant variation across the year, with the highest production occurring during summer months. The location demonstrates strong solar generation potential with daily outputs of 8.24kWh in Summer, dropping to 5.09kWh in Autumn, reaching its lowest at 4.30kWh in Winter, before climbing back up to 7.92kWh in Spring (per kW of installed capacity). This pattern indicates that while Chimbas experiences reduced output during winter, it still maintains reasonable production levels year-round.Optimal Panel Installation
For fixed solar panel installations in Chimbas, San Juan, the ideal tilt angle to maximize year-round energy production is 28 degrees facing North. This specific angle has been calculated based on the location's latitude and seasonal solar patterns to capture the maximum possible sunlight throughout the year.Environmental and Weather Considerations
Several environmental factors could potentially affect solar production in Chimbas:- Dust accumulation: The semi-arid climate of the region can lead to dust buildup on panels, reducing efficiency by up to 15% if not addressed.
- Seasonal temperature extremes: Summer temperatures frequently exceed 35°C, which can reduce panel efficiency as photovoltaic cells become less efficient at higher temperatures.
- Occasional hailstorms: While not frequent, the Andean foothills region experiences periodic hailstorms that could potentially damage panels.
Preventative Measures
To maximize energy production despite these challenges, several preventative measures can be implemented:- Regular cleaning schedule: Implementing a bi-monthly cleaning routine during drier periods can prevent significant dust accumulation.
- Temperature management: Using panels with lower temperature coefficients and ensuring adequate airflow beneath the panels can mitigate efficiency losses from high temperatures.
- Hail protection: Consider installing panels rated for hail impact or using protective covers during storm seasons.
- Seasonal angle adjustments: While 28 degrees North is optimal year-round, adjusting the angle seasonally (steeper in winter, flatter in summer) can increase annual yield by 5-8% compared to fixed installations.
Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.

Solar output per kW of installed solar PV by season in Chimbas
Seasonal solar PV output for Latitude: -31.4794, Longitude: -68.536 (Chimbas, 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 28° North in Chimbas, Argentina
To maximize your solar PV system's energy output in Chimbas, Argentina (Lat/Long -31.4794, -68.536) 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 Chimbas, 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 Chimbas, 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 |
|---|---|---|---|
| 15° North in Summer | 37° North in Autumn | 46° North in Winter | 24° 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 Chimbas, 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 Chimbas, 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 Chimbas, Argentina
The topography surrounding Chimbas, Argentina, is characterized by its position within the eastern portion of the Valle del Tulum (Tulum Valley), nestled between significant mountain ranges. To the west rise the imposing Andes Mountains, while the Sierra de Pie de Palo stands prominently to the east. This geographic positioning creates a valley landscape that is predominantly flat with a gentle slope descending from west to east. Chimbas itself sits on relatively level terrain at an elevation of approximately 630 meters above sea level. The region features an arid landscape with sparse natural vegetation, typical of the Cuyo region's desert environment. The nearby Río San Juan flows through this valley, providing an important water source in an otherwise dry region.
Surrounding Terrain Features
The western horizon is dominated by the Pre-Cordillera, the easternmost range of the Andes Mountains, which creates a dramatic backdrop rising several thousand meters above the valley floor. These mountains influence local climate patterns, including wind direction and precipitation. To the east, the Sierra de Pie de Palo range presents a significant topographical feature, with elevations reaching approximately 3,000 meters. This isolated mountain mass stands in stark contrast to the relatively flat valley where Chimbas is situated. The valley floor itself consists primarily of alluvial deposits from the Río San Juan, creating fertile soils in an otherwise arid environment. These deposits have formed a generally flat plain with minimal undulation, making much of the surrounding area physically accessible.Optimal Areas for Solar PV Development
The flat, open terrain surrounding Chimbas presents excellent opportunities for large-scale solar photovoltaic development. The most suitable areas would be found in the eastern and southeastern sectors of the valley, where several favorable conditions converge: These eastern valley sections feature extensive flat terrain with minimal slope, reducing construction complexity and costs for large solar installations. The land here experiences minimal shading from the western mountain ranges, maximizing potential sunlight exposure throughout the day. The areas east and southeast of Chimbas, extending toward the base of Sierra de Pie de Palo but not immediately adjacent to it, offer particularly promising locations. These zones combine favorable topography with sufficient distance from urban development, reducing land-use conflicts while maintaining proximity to existing electrical infrastructure. The northern valley sections also present viable options, with expansive flat areas that receive abundant sunlight. However, consideration must be given to the agricultural value of some of these lands, particularly those near irrigation networks connected to the Río San Juan. Areas immediately adjacent to the western mountain ranges would be less ideal due to potential afternoon shading effects from the Pre-Cordillera. Similarly, locations too close to the eastern Sierra de Pie de Palo might experience morning shading, though this effect would be less pronounced than western mountain shadowing. The arid climate of the region means minimal vegetation clearance would be required for solar development, reducing environmental impact and site preparation costs. The stable soil composition throughout much of the valley provides good foundation conditions for solar array structures.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.
