Jojutla, Morelos, Mexico represents an excellent location for year-round solar photovoltaic energy generation. Located in the tropics at coordinates 18.5868°N, -99.2213°W, this area benefits from consistent sunlight throughout most of the year, with seasons characterized more by wet and dry periods rather than dramatic temperature variations.

Solar Energy Production Performance

The solar energy output data for Jojutla demonstrates strong and reliable performance across all seasons. Spring emerges as the peak production period, generating 7.68 kWh per day per kW of installed solar capacity. Summer follows closely with 6.58 kWh/day per kW, while autumn and winter show more modest but still substantial output at 6.04 kWh/day and 5.96 kWh/day per kW respectively. This seasonal pattern reflects typical tropical solar conditions, where spring months often provide optimal combinations of sun angle and clear skies before the onset of summer weather patterns. The relatively small variation between seasons - with the highest production being only about 29% greater than the lowest - indicates excellent year-round reliability for solar installations. For fixed panel installations at this location, the ideal tilt angle to maximize total year-round production is 17 degrees facing south. This angle optimization takes into account the weighted solar elevation angles throughout the year and Earth's elliptical orbit patterns.

Environmental and Weather Factors

Several local factors could potentially impact solar production efficiency in Jojutla and require consideration during installation planning. The tropical wet season presents the most significant challenge, as increased cloud cover and frequent rainfall can reduce solar irradiance and create maintenance issues. Heavy rains can leave mineral deposits and debris on panel surfaces, while high humidity may contribute to faster accumulation of dust and organic matter. Dust accumulation is another important consideration, particularly during dry seasons when winds can carry fine particles that settle on solar panels and reduce their efficiency. The agricultural nature of much of the surrounding region may contribute additional airborne particles during harvest periods or land preparation activities.

Preventative Measures for Optimal Performance

Several installation and maintenance strategies can help maximize solar energy production despite these environmental challenges:

• Install panels with adequate tilt (the recommended 17 degrees south) to promote natural cleaning during rainfall
• Implement regular cleaning schedules, particularly important during dry seasons and after dust storms
• Use anti-reflective coatings that also provide easier cleaning properties
• Design mounting systems with proper drainage to prevent water pooling
• Consider automated cleaning systems for larger installations

Proper system design should also account for the tropical climate's high humidity levels by ensuring adequate ventilation around panels and using corrosion-resistant materials for mounting hardware. Regular inspection schedules become particularly important in this environment to identify and address any weather-related issues before they significantly impact performance. Despite these considerations, Jojutla's consistent solar resource and relatively minor seasonal variation make it a highly favorable location for solar PV installations, with proper planning and maintenance ensuring excellent long-term energy production.

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

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

Seasonal solar PV output for Latitude: 18.5868, Longitude: -99.2213 (Jojutla, 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 17° South in Jojutla, Mexico

To maximize your solar PV system's energy output in Jojutla, Mexico (Lat/Long 18.5868, -99.2213) throughout the year, you should tilt your panels at an angle of 17° 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 Jojutla, 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 Jojutla, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 17° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
3° South in Summer	24° South in Autumn	34° South in Winter	12° 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 Jojutla, 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 Jojutla, 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 Jojutla, Mexico

Topographical Features of Jojutla Region

Jojutla sits in the southern portion of Morelos state, positioned within a transitional zone where the Mexican highlands begin their descent toward lower elevations. The city itself rests at approximately 900 meters above sea level, nestled in a valley that forms part of the broader Balsas River basin. This positioning creates a landscape characterized by rolling hills and gentle slopes rather than dramatic mountainous terrain.

The surrounding topography consists primarily of undulating terrain with moderate elevation changes. To the north and east, the land gradually rises toward the volcanic peaks that define much of central Mexico's geography, while southward the elevation decreases as the landscape opens toward the warmer lowlands of Guerrero state. The local relief rarely exceeds 200-300 meters of variation within a 10-kilometer radius of the city center.

Several seasonal watercourses and small rivers traverse the area, creating modest valleys and ridgelines that give the landscape its characteristic rolling appearance. The terrain is generally well-drained, with slopes that are neither too steep for development nor completely flat, providing natural drainage patterns that help prevent waterlogging during the rainy season.

Optimal Areas for Large-Scale Solar Development

The most promising locations for extensive solar photovoltaic installations lie on the broad, gently sloping plateaus that extend southward and westward from Jojutla. These areas offer relatively flat terrain with gradual south-facing slopes that would naturally optimize solar panel orientation without requiring extensive grading or earthwork.

The elevated plains approximately 5-15 kilometers southwest of the city center present particularly favorable conditions. This zone combines gentle topography with good accessibility via existing road networks, while remaining sufficiently distant from dense residential areas to accommodate large-scale infrastructure development. The natural drainage patterns in this area also reduce concerns about seasonal flooding that might affect equipment.

Areas to the southeast, where the landscape opens toward the Balsas River valley, offer another excellent opportunity for solar development. The terrain here is notably flatter than the more mountainous regions to the north, and the slightly lower elevation provides additional protection from the more extreme weather patterns that can affect higher-altitude locations.

The rolling hills immediately north of Jojutla, while scenic, present more challenges for large-scale solar installations due to their steeper gradients and more complex terrain. However, some of the broader ridgetops in this area could accommodate smaller solar arrays, particularly those designed to follow the natural contours of the landscape rather than requiring extensive site preparation.
