Tekax, Yucatán, Mexico represents a very favorable location for year-round solar photovoltaic energy generation. Located in the tropical region of the Yucatan Peninsula, this area benefits from consistent sunlight throughout most of the year, with seasonal variations characterized more by wet and dry periods rather than the dramatic temperature and daylight changes seen in temperate climates.

Seasonal Solar Energy Production

The solar energy output at Tekax shows strong performance across all seasons, with spring delivering the highest production at 6.72 kWh per day per kW of installed solar capacity. Summer follows closely with 6.50 kWh/day, while autumn provides 5.65 kWh/day. Even during the lowest-producing season of winter, the location still generates a respectable 4.84 kWh/day per kW installed. Spring and summer represent the ideal times for solar generation at this location, offering approximately 39% more energy production compared to the winter months. This seasonal pattern aligns well with typical energy demand cycles in tropical regions.

Optimal Panel Installation

For maximum year-round solar energy production at Tekax, Yucatán, fixed solar panels should be tilted at an angle of 18 degrees facing south. This optimal angle is calculated by analyzing daily solar elevation angles throughout the year, determining the best panel positioning for each day, and then weighting these angles based on the actual solar energy potential using NASA solar irradiance data to arrive at the ideal annual average tilt.

Environmental and Weather Challenges

Several significant environmental factors at Tekax could potentially impact solar energy production and require careful consideration during installation:

• Tropical storms and hurricanes: The Yucatan Peninsula lies within the Atlantic hurricane belt, with the hurricane season typically running from June through November
• Heavy rainfall during wet season: Intense precipitation can reduce solar output and create maintenance challenges
• High humidity and salt air: The proximity to coastal areas means elevated moisture levels and potential salt corrosion
• Dust and debris accumulation: Dry season conditions can lead to dust buildup on panels

Preventative Measures for Optimal Performance

To maximize solar energy production despite these environmental challenges, several installation strategies should be implemented:

• Hurricane-resistant mounting systems: Use reinforced mounting structures designed to withstand high winds, with proper engineering certifications for tropical storm conditions
• Corrosion-resistant materials: Select aluminum frames and stainless steel hardware with marine-grade coatings to resist humidity and salt air degradation
• Adequate drainage design: Ensure proper water runoff from panels and mounting areas to prevent standing water and potential electrical issues
• Regular maintenance schedule: Implement frequent cleaning protocols, especially during dry seasons, to remove dust and debris that can reduce efficiency
• Quality electrical components: Use weatherproof inverters and electrical connections rated for high-humidity tropical environments

Despite these environmental considerations, Tekax remains an excellent location for solar energy generation. With proper installation techniques and regular maintenance, solar PV systems can operate efficiently year-round while withstanding the tropical climate challenges typical of this region.

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

Seasonal solar PV output for Latitude: 19.9333, Longitude: -89.3005 (Tekax, 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 18° South in Tekax, Mexico

To maximize your solar PV system's energy output in Tekax, Mexico (Lat/Long 19.9333, -89.3005) throughout the year, you should tilt your panels at an angle of 18° 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 Tekax, 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 Tekax, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 18° 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	25° 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 Tekax, 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 Tekax, 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 Tekax, Mexico

Topographical Features Around Tekax

The landscape surrounding Tekax in the Yucatan Peninsula of Mexico is characterized by relatively flat terrain with gentle undulations typical of the broader Yucatecan plain. This region sits on a vast limestone platform that extends across much of the peninsula, creating a generally level topography with elevations rarely exceeding 200 meters above sea level. The area around Tekax features subtle rolling hills and shallow depressions, with the terrain gradually rising toward the Puuc Hills to the north and northwest. The underlying geology consists primarily of porous limestone bedrock, which creates unique surface features including cenotes (natural sinkholes) and underground cave systems. The landscape is dotted with these circular depressions where the limestone has collapsed, revealing access to the extensive underground water table that characterizes the region. Between these natural formations, the land presents broad, relatively flat expanses of scrubland and agricultural areas. Vegetation in the area consists mainly of tropical dry forest and secondary growth, with patches of cultivated land interspersed throughout. The natural forest canopy is generally low to medium height, dominated by deciduous trees that shed their leaves during the dry season. Agricultural areas typically feature henequen plantations, corn fields, and cattle pastures, creating a mosaic of land uses across the gently rolling terrain.

Optimal Areas for Large-Scale Solar Development

The expansive flat to gently rolling terrain surrounding Tekax presents excellent opportunities for large-scale solar photovoltaic installations. The most suitable areas lie to the east and southeast of the town, where extensive stretches of relatively level land offer minimal topographical constraints for solar array placement. These areas benefit from consistent terrain that would require minimal grading and site preparation, reducing overall project costs. The agricultural zones that have been cleared of native forest represent particularly attractive locations for solar development. These areas already have established access routes and have been leveled for farming purposes, making them ideal candidates for conversion to solar energy production. The existing infrastructure, including rural roads and proximity to electrical transmission lines, further enhances the viability of these locations. Areas with sparse vegetation and lower agricultural productivity would be especially well-suited for solar installations, as they would minimize conflicts with existing land uses. The limestone substrate provides stable ground conditions for mounting systems, while the generally flat topography allows for optimal panel orientation and spacing. The absence of significant elevation changes means that shading between panel rows can be minimized, maximizing the efficiency of large-scale installations. The region's low population density and abundance of available land create favorable conditions for utility-scale solar projects. Large contiguous parcels of suitable terrain are readily available, allowing for the development of substantial solar farms that could serve regional energy needs while taking advantage of the area's excellent solar resource potential.
