Coacalco, México, Mexico, situated at latitude 19.6272 and longitude -99.1051, offers a promising location for solar energy generation throughout the year. This tropical setting benefits from consistent sunlight, with seasons characterized more by wet and dry periods rather than significant temperature fluctuations.

The solar potential in Coacalco demonstrates a relatively stable output across seasons, with some notable variations. Spring emerges as the most productive season, yielding an impressive 7.24 kWh per day for each kilowatt of installed solar capacity. Winter follows with 5.89 kWh/day, while summer and autumn produce 5.71 kWh/day and 5.48 kWh/day, respectively.

Optimal Panel Positioning

To maximize year-round solar energy production in Coacalco, México, fixed solar panels should be tilted at a 19-degree angle facing south. This optimal angle ensures the panels capture the most sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific solar elevation angles.

Peak Production Periods

The most ideal time for solar energy generation in Coacalco is during the spring months. This period offers the highest daily output, likely due to clearer skies and optimal sun angles. However, the relatively consistent output across seasons suggests that solar PV systems can be effective year-round in this location.

Environmental Considerations

While Coacalco's tropical climate is generally favorable for solar energy production, there are some environmental factors to consider:

1. Dust and air pollution: Being close to Mexico City, Coacalco may experience periods of increased air pollution and dust, which can reduce panel efficiency.
2. Rainy season: The wet season, typically from June to October, may lead to temporary reductions in solar output due to cloud cover.

To mitigate these issues, regular panel cleaning and maintenance should be scheduled, especially during drier periods when dust accumulation is more likely. Additionally, investing in high-quality, weather-resistant panels can help maintain efficiency during the rainy season.

Overall, Coacalco presents a highly suitable location for solar PV installations, with consistent year-round production and particularly strong output during the spring months. With proper installation and maintenance, solar energy systems in this area can provide a reliable and sustainable source of electricity throughout the year.

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

Seasonal solar PV output for Latitude: 19.6272, Longitude: -99.1051 (Coacalco, 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 Coacalco, Mexico

To maximize your solar PV system's energy output in Coacalco, Mexico (Lat/Long 19.6272, -99.1051) 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 Coacalco, 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 Coacalco, 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 Coacalco, 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 Coacalco, 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 Coacalco, Mexico

Coacalco, Mexico, situated at latitude 19.6272 and longitude -99.1051, is located in the central part of Mexico, just north of Mexico City. The topography of the area surrounding Coacalco is characterized by a mix of flat valleys and rolling hills, with some more mountainous terrain to the west and north. The immediate vicinity of Coacalco is primarily flat to gently sloping, as it sits in the Valley of Mexico. This valley is a large basin surrounded by mountains and volcanoes, creating a diverse landscape in the broader region. To the east and south of Coacalco, the terrain remains relatively flat, extending towards the urban sprawl of Mexico City and its surrounding municipalities. As you move westward from Coacalco, the landscape becomes more varied, with hills and small mountains beginning to rise. The Sierra de Guadalupe mountain range lies to the northwest, providing a striking backdrop to the area. These mountains, while not extremely tall, offer a significant change in elevation compared to the valley floor.

Areas Suitable for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Coacalco, several factors come into play. The most suitable areas would typically be those with ample flat or gently sloping land, good sun exposure, and minimal environmental or urban constraints. The flat areas to the east and south of Coacalco present promising opportunities for solar PV development. These regions offer expansive, open spaces that could accommodate large arrays of solar panels. The relatively level terrain would minimize the need for extensive land preparation, potentially reducing installation costs. Another potentially suitable area lies to the northeast of Coacalco, where there are some larger tracts of undeveloped land. This region, while still relatively flat, may offer a good balance between proximity to urban areas (for energy distribution) and available space for solar installations. It's important to note that while the hilly areas to the west might seem attractive due to their elevation, they may not be ideal for large-scale solar PV. The uneven terrain could complicate installation and maintenance, and the potential for shading from nearby hills could reduce overall energy production efficiency. Any large-scale solar PV project in this region would need to carefully consider factors such as land use regulations, environmental impact, and proximity to existing power infrastructure. Additionally, given the area's proximity to Mexico City, developers would need to balance the need for renewable energy with the expanding urban and suburban land requirements of the growing metropolitan area.
