Solar PV Analysis of Aguascalientes, Mexico
Aguascalientes, Mexico, located at latitude 21.8913 and longitude -102.2204, offers a promising environment for solar energy generation. Situated in the tropics, this location benefits from consistent sunlight throughout most of the year, with seasons characterized more by wet and dry periods rather than significant temperature variations.
Seasonal Solar Performance
The solar energy potential in Aguascalientes varies across the meteorological seasons. Spring stands out as the most productive season, with an impressive daily output of 8.30 kWh per kW of installed solar capacity. Summer follows with 6.66 kWh/day, while winter and autumn show slightly lower but still substantial outputs of 5.99 kWh/day and 5.92 kWh/day, respectively.
These figures indicate that Aguascalientes is an excellent location for year-round solar energy production, with spring being the peak season. The relatively high output during winter months is particularly noteworthy, as many locations experience significant drops in solar production during this time.
Optimal Panel Positioning
To maximize year-round solar energy production in Aguascalientes, fixed solar panels should be tilted at an angle of 21 degrees facing south. This optimal angle takes into account the location's latitude, the Earth's elliptical orbit, and daily solar elevation angles throughout the year.
Environmental Considerations
While Aguascalientes presents favorable conditions for solar energy production, there are a few environmental factors to consider. The region experiences a semi-arid climate, which can lead to dust accumulation on solar panels. Regular cleaning and maintenance of the panels can help mitigate this issue and ensure optimal performance.
Additionally, Aguascalientes has a rainy season typically lasting from June to September. While this may temporarily reduce solar output, it can also help naturally clean the panels. Installing panels at the recommended tilt angle can assist with water runoff and self-cleaning during rain events.
Preventative Measures
To enhance solar energy production in Aguascalientes, consider implementing the following measures:
- Use anti-reflective coatings on solar panels to reduce dust adhesion and improve light absorption.
- Install a monitoring system to detect any drops in performance due to dust accumulation or other issues.
- Implement a regular cleaning schedule, especially during the dry season.
In conclusion, Aguascalientes offers an ideal location for solar PV installations, with consistent year-round production and particularly high output during spring months. With proper installation and maintenance, solar energy systems in this region can be highly effective and reliable.

Solar output per kW of installed solar PV by season in Aguascalientes
Seasonal solar PV output for Latitude: 21.8913, Longitude: -102.2204 (Aguascalientes, Mexico), 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 21° South in Aguascalientes, Mexico
To maximize your solar PV system's energy output in Aguascalientes, Mexico (Lat/Long 21.8913, -102.2204) throughout the year, you should tilt your panels at an angle of 21° South 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 Aguascalientes, Mexico
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 Aguascalientes, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 21° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 6° South in Summer | 28° South in Autumn | 37° South in Winter | 15° South 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 Aguascalientes, Mexico
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 Aguascalientes, Mexico.
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 Aguascalientes, Mexico
The topography around Aguascalientes, Mexico, is characterized by a diverse landscape that includes both flat areas and hilly terrain. The city itself is situated in a valley, surrounded by low mountains and rolling hills. To the east and northeast of Aguascalientes, you'll find the Sierra Fría mountain range, which features higher elevations and more rugged terrain. To the west and southwest, the landscape becomes more level, transitioning into the expansive plains of the Mexican Plateau.
The region around Aguascalientes experiences a semi-arid climate, with relatively low rainfall and plenty of sunshine throughout the year. This combination of topography and climate creates several areas that could be well-suited for large-scale solar photovoltaic (PV) installations.
The most promising areas for solar PV development would likely be found in the flatter regions to the west and southwest of Aguascalientes. These areas offer several advantages for solar energy production:
- Ample flat land: The level terrain in these areas provides large, unobstructed spaces for solar panel arrays, minimizing the need for extensive land preparation.
- Minimal shading: With fewer hills and mountains, there's less risk of natural features casting shadows on the solar panels, ensuring maximum sun exposure throughout the day.
- Ease of access: Flatter terrain generally allows for easier construction and maintenance of solar facilities, as well as better road access for equipment transportation.
- Lower competition for land use: These areas may have less agricultural or urban development, potentially making land acquisition simpler and more cost-effective.
While the western and southwestern regions appear most suitable, it's important to note that specific site selection would require detailed environmental and technical assessments. Factors such as local weather patterns, soil conditions, and proximity to existing electrical infrastructure would all play crucial roles in determining the optimal locations for large-scale solar PV projects in the Aguascalientes area.
