Tlalnepantla, México, Mexico, situated at 19.5412° N, 99.1666° W, offers a promising location for solar energy generation throughout the year. This tropical setting benefits from consistent sunlight, with seasons primarily distinguished by wet and dry periods rather than significant temperature variations.

Seasonal Solar Performance

Solar panel efficiency in Tlalnepantla demonstrates remarkable consistency across seasons. Spring stands out as the most productive period, with an impressive daily output of 7.24 kWh per kW of installed solar capacity. Winter follows closely, generating 5.89 kWh/day, while summer and autumn produce 5.71 kWh/day and 5.48 kWh/day, respectively.

Optimal Panel Positioning

For fixed panel installations in Tlalnepantla, México, the ideal tilt angle to maximize year-round solar production is 19 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the location's latitude and the Earth's elliptical orbit.

Peak Production Periods

While solar energy generation remains relatively stable year-round, spring emerges as the prime season for solar production in Tlalnepantla. The increased output during this period can be attributed to clearer skies and optimal sun angles. However, the consistent performance across all seasons underscores the location's suitability for year-round solar energy harvesting.

Environmental Considerations

Despite the favorable conditions, Tlalnepantla faces some environmental challenges that could impact solar production: 1. Air pollution: Being part of the Mexico City metropolitan area, Tlalnepantla may experience periods of high air pollution, potentially reducing solar panel efficiency. 2. Dust accumulation: The region's dry seasons can lead to increased dust, which may settle on solar panels and decrease their effectiveness. To mitigate these issues, regular panel cleaning and maintenance are crucial. Installing panels at a slight angle (as recommended) can help with natural dust removal during rainfall. Additionally, considering anti-soiling coatings for the panels can enhance their resistance to dust and pollutants. In conclusion, Tlalnepantla presents an ideal location for solar PV installations, with consistent year-round production and particularly high output during spring. By addressing potential environmental factors through proper maintenance and preventive measures, solar energy systems in this area can operate at optimal efficiency throughout the year.

Solar output per kW of installed solar PV by season in Tlalnepantla

Seasonal solar PV output for Latitude: 19.5412, Longitude: -99.1666 (Tlalnepantla, 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 19° South in Tlalnepantla, Mexico

To maximize your solar PV system's energy output in Tlalnepantla, Mexico (Lat/Long 19.5412, -99.1666) throughout the year, you should tilt your panels at an angle of 19° 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 Tlalnepantla, 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 Tlalnepantla, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 19° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
4° South in Summer	26° South in Autumn	35° South in Winter	13° 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 Tlalnepantla, 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 Tlalnepantla, Mexico.

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 Tlalnepantla, Mexico

The topography around Tlalnepantla, Mexico, is characterized by a diverse landscape that includes both flat areas and hilly terrain. Tlalnepantla is situated in the Valley of Mexico, a large basin surrounded by mountains and volcanoes. The city itself lies on relatively flat land, but as you move outward from the urban center, the terrain becomes more varied. To the west and northwest of Tlalnepantla, the land gradually rises into the foothills of the Sierra de las Cruces mountain range. These hills provide a stark contrast to the flatter areas of the city and offer scenic views of the surrounding region. The eastern and southern parts of Tlalnepantla are generally flatter, blending into the broader Valley of Mexico.

Potential Areas for Large-Scale Solar PV

When considering areas suitable for large-scale solar photovoltaic (PV) installations near Tlalnepantla, the flatter regions to the east and south would be most appropriate. These areas offer several advantages for solar energy production: Firstly, the relatively level terrain in these directions makes it easier and more cost-effective to install large arrays of solar panels. Flat land requires less preparation and allows for a more uniform layout of the panels, optimizing their exposure to sunlight. Secondly, these areas are less likely to be affected by shadowing from nearby hills or mountains, which could reduce the efficiency of solar panels. The open, expansive nature of the terrain in the eastern and southern parts of the region allows for maximum sun exposure throughout the day. Additionally, these flatter areas are often less densely populated than the urban center of Tlalnepantla or the hilly regions to the west. This means there may be more available land for large-scale solar installations without conflicting with existing residential or commercial developments. However, it's important to note that any large-scale solar PV project would require detailed environmental and land-use studies. Factors such as local climate conditions, proximity to power transmission infrastructure, and potential impact on local ecosystems would need to be carefully considered before determining the most suitable locations for solar energy development in the region.
