Spring clearly stands out as the optimal season for solar energy generation, producing nearly 34% more energy than autumn, which has the lowest output. This spring peak is likely due to clear skies, moderate temperatures, and optimal sun angles during this season.

Optimal Panel Installation

For fixed solar panel installations in Tezontepec de Aldama, the ideal tilt angle to maximize year-round energy production is 19 degrees facing South. This angle has been calculated by analyzing the daily solar elevation patterns at this specific latitude, weighted by the solar irradiance potential throughout the year.

Environmental and Weather Considerations

Several environmental factors could impact solar production at this location. The region experiences a rainy season (typically June through September), which may reduce solar output due to cloud cover and precipitation. Dust accumulation is another consideration in this semi-arid region, as it can gradually reduce panel efficiency if not addressed. To mitigate these challenges, solar installations should incorporate: 1. Regular cleaning schedules, especially during the dry season when dust accumulation is highest 2. Slight adjustments to the tilt angle (perhaps 1-2 degrees steeper) to facilitate natural cleaning during rainfall 3. Weather-resistant components that can withstand seasonal temperature variations

Conclusion

Overall, Tezontepec de Aldama offers excellent conditions for solar PV installations with good year-round production. The annual average daily production of approximately 6.23 kWh per kW installed makes solar investments in this location economically attractive. While there is some seasonal variation, even the lowest-producing season (autumn) delivers respectable output, making this a reliable location for consistent solar energy generation throughout the year.

Solar output per kW of installed solar PV by season in Tezontepec De Aldama

Seasonal solar PV output for Latitude: 20.1831, Longitude: -99.263 (Tezontepec De Aldama, 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 Tezontepec De Aldama, Mexico

To maximize your solar PV system's energy output in Tezontepec De Aldama, Mexico (Lat/Long 20.1831, -99.263) 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 Tezontepec De Aldama, 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 Tezontepec De Aldama, 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	14° 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 Tezontepec De Aldama, 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 Tezontepec De Aldama, 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 Tezontepec De Aldama, Mexico

The landscape surrounding Tezontepec de Aldama in the Mexican state of Hidalgo presents a diverse topographical profile characterized by a combination of valleys, hills, and low mountains. This municipality sits at an elevation of approximately 2,100 meters above sea level, within the southern portion of the Mezquital Valley region.

Topographical Features

The terrain around Tezontepec de Aldama can be described as semi-mountainous with undulating hills interspersed with flatter valley areas. To the north and northwest, the landscape gradually transitions into the broader Mezquital Valley, which features more level terrain. The southern and eastern portions display more pronounced elevation changes, with hills rising to form part of the Trans-Mexican Volcanic Belt's northern edges. Several seasonal streams and small rivers cross the area, carving shallow valleys between the hills. The Tula River basin influences the regional drainage patterns, with water generally flowing northward. This creates a landscape of alternating ridges and drainage channels throughout the municipality. The soil composition varies across the region, with volcanic-derived soils predominant in many areas. These soils range from relatively fertile in the valley bottoms to thinner, rockier substrates on hillsides and elevated areas.

Climate and Vegetation

The climate in Tezontepec de Aldama is classified as semi-arid to temperate, which has shaped both the natural vegetation and land use patterns. Native vegetation consists primarily of xerophytic plants adapted to the relatively dry conditions, including various cacti, mesquite, and drought-resistant shrubs on the hillsides. In valley areas with better water access, more diverse vegetation can be found. Agricultural activities have modified significant portions of the landscape, particularly in flatter areas where irrigation is feasible. This human influence has created a patchwork of cultivated fields interspersed with areas of natural vegetation, especially on steeper slopes less suitable for farming.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic installations, the most suitable areas near Tezontepec de Aldama would be the gently sloping or flat terrains found primarily in the northern and northwestern portions of the municipality, extending into the broader Mezquital Valley. These areas offer several advantages: The relatively level terrain reduces construction costs and simplifies the installation of solar arrays. These locations typically require minimal grading and earthwork, making development more economical and less environmentally disruptive. The semi-arid climate means less cloud cover throughout the year, maximizing solar energy potential. The natural vegetation in these areas is already adapted to high solar exposure, indicating favorable conditions for photovoltaic generation. The lower-lying areas to the north and northwest, where the topography flattens out toward the Mezquital Valley proper, provide expansive spaces that could accommodate large installations. These areas tend to have fewer competing land uses compared to the more agriculturally productive or densely populated zones. Areas with southern exposure on gentle slopes (5-15 degree incline) can also be advantageous for solar development, as they naturally orient toward the sun's path. Several such locations can be found in the transitional zones between the valley floor and the rising hills to the south and east. Less optimal would be the steeper hillsides and more rugged terrain to the south and southeast, where installation costs would increase significantly due to the need for extensive site preparation. Additionally, areas near water courses or seasonal flood zones should be avoided to prevent damage to solar infrastructure.
