Solar Energy Potential in Texcoco, México, Mexico

Texcoco, México, Mexico, located at latitude 19.4864° N and longitude 98.8861° W, offers excellent conditions for solar PV energy generation throughout the year. This location in the tropics benefits from consistent sunlight patterns that make it highly suitable for solar energy production. The seasonal electricity output from solar PV systems in Texcoco shows remarkable consistency with some variation. During Spring, the location reaches its peak performance with an impressive 7.25 kWh per day for each kilowatt of installed capacity. Summer and Winter both deliver a solid 5.86 kWh per day, while Autumn provides a slightly lower but still strong 5.60 kWh per day. For anyone installing fixed solar panels in Texcoco, México, the ideal tilt angle to maximize year-round energy production is 19 degrees facing South. This specific angle has been calculated to optimize solar capture throughout the year, accounting for the Earth's elliptical orbit and Texcoco's particular latitude.

Local Factors Affecting Solar Production

Despite the favorable conditions, several local factors could potentially impact solar energy production in Texcoco:

• Air pollution from nearby Mexico City may reduce solar irradiance, particularly during winter months when thermal inversions can trap pollutants in the Valley of Mexico
• Seasonal dust storms during the dry season (winter to early spring) can accumulate on panels, reducing efficiency
• Occasional hailstorms, though rare, may pose a risk to panel integrity

Preventative measures to address these challenges include installing panels with self-cleaning hydrophobic coatings to minimize dust accumulation, implementing regular maintenance schedules during the dry season, and selecting hail-resistant panels with tempered glass. Additionally, slightly increasing the tilt angle beyond the optimal 19 degrees can help with natural cleaning during rainfall events. The area's high altitude (approximately 2,250 meters above sea level) actually provides an advantage, as the thinner atmosphere allows more solar radiation to reach the panels, partially offsetting any losses from pollution. Overall, with proper installation and maintenance, Texcoco represents a prime location for solar energy production throughout the year, with Spring offering the highest generation potential.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 358 locations across Mexico. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 19° South in Texcoco, Mexico

To maximize your solar PV system's energy output in Texcoco, Mexico (Lat/Long 19.4864, -98.8861) 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 Texcoco, 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 Texcoco, 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 Texcoco, 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 Texcoco, 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 Texcoco, Mexico

Texcoco is situated in the northeastern part of the Valley of Mexico, about 25 kilometers east of Mexico City. The topography of the region is characterized by a diverse landscape that includes a former lakebed, sloping foothills, and mountainous terrain to the east. The city itself sits at an elevation of approximately 2,250 meters (7,380 feet) above sea level on what was once the eastern shore of Lake Texcoco, a vast lake that dominated the Valley of Mexico before colonial drainage projects. The former lakebed creates a relatively flat plain that extends westward from the city toward Mexico City. This basin area has minimal elevation changes, creating extensive level terrain.

Mountain Ranges and Elevations

To the east of Texcoco, the landscape rises dramatically into the Sierra Nevada mountain range. This mountainous region includes notable peaks such as Tláloc and Telapón, with elevations exceeding 4,000 meters (13,000 feet) above sea level. The transition from the flat former lakebed to these mountains creates a varied topographical profile with progressively steeper slopes as one moves eastward. The northern and southern approaches to Texcoco feature gently rolling hills that gradually increase in elevation. These transitional zones between the flat valley floor and the eastern mountains contain numerous ravines and seasonal waterways that have carved shallow valleys into the landscape.

Potential for Solar PV Development

The former lakebed areas west of Texcoco present the most favorable conditions for large-scale solar photovoltaic installations. These areas offer several advantages: The flat terrain minimizes the need for extensive grading and earthwork during construction, reducing development costs. The open expanses allow for efficient panel layout configurations that can maximize energy capture throughout the day. The limited vegetation and agricultural activity in some portions of the former lakebed reduce potential land use conflicts. The gently sloping foothills to the east of Texcoco, before the terrain becomes too steep, also offer potential for solar development. These areas receive consistent sunlight exposure and have adequate drainage to prevent flooding concerns. The slightly elevated position can reduce dust accumulation on panels compared to valley floor installations.

Topographical Challenges

The mountainous regions east of Texcoco, while receiving abundant sunlight at higher elevations, present significant challenges for large-scale solar development. The steep slopes make construction difficult and expensive, while the rugged terrain complicates access for maintenance vehicles and equipment delivery. Additionally, these areas often have greater ecological sensitivity and may be subject to more stringent environmental regulations. Areas immediately adjacent to seasonal waterways should be avoided due to potential flooding and erosion risks. Some portions of the former lakebed may have poor soil stability or seasonal flooding issues that would require additional engineering considerations. The topography around Texcoco creates a climate gradient, with the higher eastern elevations typically experiencing cooler temperatures than the valley floor. This temperature differential can affect solar panel efficiency, with the moderate temperatures of the middle elevations often providing optimal operating conditions for photovoltaic systems.
