Pichucalco, Chiapas, Mexico represents a highly favorable location for year-round solar photovoltaic energy generation. Located in the tropics at coordinates 17.5077, -93.1, this region benefits from consistent sunlight throughout most of the year, with seasonal variations typically defined by wet and dry periods rather than the temperature-driven seasons found in temperate climates.
Solar Energy Output Performance
The solar energy production data for Pichucalco demonstrates strong year-round generation potential. Summer months deliver the highest output at 6.18 kWh per day per installed kilowatt, closely followed by spring at 6.04 kWh per day per kilowatt. Autumn production drops to 4.95 kWh per day per kilowatt, while winter shows the lowest output at 4.38 kWh per day per kilowatt. The most productive periods for solar generation occur during the warmer months of spring and summer, when the sun's angle is most favorable for this latitude. Even during the less productive winter months, the location still maintains reasonable solar output, making it suitable for consistent year-round energy production. For optimal performance with fixed panel installations at this location, solar panels should be tilted at 15 degrees facing south. This angle maximizes total annual energy production by accounting for the sun's varying position throughout the year and the specific solar conditions at this tropical latitude.Environmental and Weather Challenges
Several significant factors in Pichucalco's tropical climate can impact solar energy production and require careful consideration during installation planning. The region's pronounced wet season brings heavy rainfall and high humidity levels. Extended periods of cloud cover during rainy months can substantially reduce solar irradiance, directly impacting energy output. The high moisture content in the air can also affect equipment performance and longevity. Dust accumulation presents another challenge, particularly during dry periods. Airborne particles can settle on panel surfaces, creating a film that blocks sunlight and reduces efficiency. In tropical agricultural areas like Pichucalco, Chiapas, this dust may include organic matter and pollen that can be particularly stubborn to remove. Tropical storms and severe weather events pose risks to solar installations. High winds, hail, and intense rainfall can damage panels, mounting systems, and electrical components if not properly protected.Preventative Installation Measures
Several strategies can help maximize solar energy production despite these environmental challenges:- Install panels with adequate tilt (the recommended 15-degree angle helps with natural rain cleaning)
- Implement robust mounting systems designed for high wind loads typical of tropical storm conditions
- Use corrosion-resistant materials and protective coatings suitable for high-humidity environments
- Design drainage systems to prevent water accumulation around electrical components
- Plan for regular cleaning schedules, particularly during dust-heavy dry seasons

Solar output per kW of installed solar PV by season in Pichucalco
Seasonal solar PV output for Latitude: 17.5077, Longitude: -93.1 (Pichucalco, 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 15° South in Pichucalco, Mexico
To maximize your solar PV system's energy output in Pichucalco, Mexico (Lat/Long 17.5077, -93.1) throughout the year, you should tilt your panels at an angle of 15° 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 Pichucalco, 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 Pichucalco, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 15° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 2° South in Summer | 23° South in Autumn | 33° South in Winter | 11° 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 Pichucalco, 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 Pichucalco, Mexico
Topographical Features of Pichucalco
Pichucalco sits in the northern region of Chiapas state, positioned within the Gulf Coastal Plain where the terrain transitions from the mountainous interior of Chiapas toward the flat lowlands approaching the Gulf of Mexico. The municipality lies at a relatively modest elevation, with the town center situated on gently rolling hills that characterize much of this transitional zone between highland and coastal plain environments. The landscape around Pichucalco features undulating terrain with moderate slopes and occasional flat areas, particularly as one moves northward toward the Tabasco state border. The region forms part of the broader Grijalva River basin system, with numerous small streams and tributaries creating a network of shallow valleys and ridgelines throughout the area. These waterways have carved gentle depressions in the landscape over time, creating a terrain that alternates between low hills and valley bottoms.Regional Geological Context
The underlying geology consists primarily of sedimentary formations typical of the Gulf Coastal Plain, with layers of limestone, sandstone, and clay deposits that have been shaped by both fluvial processes and gradual tectonic uplift. This geological foundation contributes to the area's generally stable terrain, though the presence of clay-rich soils in some locations can present challenges for heavy construction projects. Vegetation in the region reflects the transition between tropical highlands and coastal plains, with areas of secondary forest, agricultural lands, and pasturelands creating a mosaic landscape. The natural drainage patterns follow the gentle topographical gradients, with water generally flowing northward toward larger tributary systems that eventually reach the Grijalva River.Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations around Pichucalco would be the flatter agricultural areas and pasturelands, particularly those found in the northern portions of the municipality. These areas offer several advantages including gentler slopes that require minimal grading, existing access roads developed for agricultural purposes, and open spaces with reduced tree coverage that would minimize clearing requirements. The elevated plateaus and ridge tops scattered throughout the region present additional opportunities for solar development, as these locations typically receive consistent exposure throughout the day and often have lower vegetation density. However, access to these elevated areas would need careful consideration during project planning. Areas near existing agricultural operations may prove particularly attractive for solar development, as the infrastructure for road access and electrical connections often already exists in these locations. The transition zones between agricultural land and natural areas could provide suitable development sites while minimizing impacts on either intensive farming operations or intact forest areas. The relatively stable geological conditions throughout the region mean that most areas would be suitable from a foundation and structural perspective, though detailed geotechnical analysis would be necessary for any specific site to address local soil conditions and drainage patterns.Mexico solar PV Stats as a country
Mexico ranks 18th in the world for cumulative solar PV capacity, with 7,040 total MW's of solar PV installed. This means that 3.20% of Mexico's total energy as a country comes from solar PV (that's 28th in the world). Each year Mexico is generating 55 Watts from solar PV per capita (Mexico ranks 50th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Mexico?
