Summer follows closely behind with 6.08 kWh/day, while autumn and winter produce 5.48 kWh/day and 4.84 kWh/day, respectively. These figures indicate that Chetumal is well-suited for year-round solar energy production, with only a modest decline during the winter months. The consistent output throughout the year makes it an ideal location for solar PV installations, as it ensures a reliable energy supply across all seasons.

Optimal Panel Tilt

For fixed solar panel installations in Chetumal, Quintana Roo, the ideal tilt angle to maximize year-round energy production is 17 degrees facing south. This angle has been calculated taking into account the city's latitude, the Earth's elliptical orbit, and daily solar elevation angles, weighted by the potential daily PV output based on NASA's solar irradiance data.

Environmental Considerations

While Chetumal's location is generally favorable for solar energy production, there are a few environmental factors to consider: 1. Hurricanes: The city's coastal location makes it vulnerable to tropical storms and hurricanes, which could potentially damage solar installations. 2. High humidity: The tropical climate brings high humidity levels, which may lead to accelerated wear on solar equipment. To mitigate these risks, several preventative measures can be taken during solar panel installation:

• Use hurricane-resistant mounting systems and frames designed to withstand high winds
• Install protective barriers or windbreaks around the solar array
• Choose corrosion-resistant materials for all components to combat humidity-related degradation
• Implement regular maintenance schedules to address any weather-related wear and tear

By taking these precautions, solar energy systems in Chetumal can maintain high levels of productivity and longevity, making the most of the city's excellent solar potential.

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 Chetumal

Seasonal solar PV output for Latitude: 18.5117, Longitude: -88.3008 (Chetumal, 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 Chetumal, Mexico

To maximize your solar PV system's energy output in Chetumal, Mexico (Lat/Long 18.5117, -88.3008) 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 Chetumal, 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 Chetumal, 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 Chetumal, 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 Chetumal, 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 Chetumal, Mexico

Chetumal, the capital city of Quintana Roo state in Mexico, is situated in a unique topographical setting. The city lies on the eastern coast of the Yucatán Peninsula, near the mouth of the Río Hondo, which forms the border between Mexico and Belize. The surrounding landscape is predominantly flat, characteristic of the Yucatán Peninsula's limestone platform. The area around Chetumal is characterized by low-lying coastal plains and wetlands. To the north and west of the city, the terrain gradually rises into a gently rolling landscape with occasional small hills. This region is part of the larger Yucatán Peninsula karst, featuring numerous sinkholes (cenotes) and underground rivers typical of limestone formations. South of Chetumal, the land transitions into a vast system of lagoons and mangrove swamps, including the expansive Chetumal Bay. These wetlands play a crucial role in the local ecosystem and provide natural protection against coastal erosion and storms.

Potential for Large-Scale Solar PV

When considering areas suitable for large-scale solar photovoltaic (PV) installations near Chetumal, several factors come into play. The most promising locations would be found in the slightly elevated areas to the north and west of the city. These regions offer several advantages for solar energy development: Firstly, the gently rolling terrain provides better drainage and reduces the risk of flooding, which is crucial for protecting solar infrastructure. The slightly higher elevation also tends to experience less fog and humidity compared to the coastal areas, potentially increasing solar panel efficiency. Secondly, these inland areas are generally less ecologically sensitive than the coastal wetlands and mangrove forests. Developing solar farms here would likely have a lower environmental impact and face fewer regulatory hurdles. Thirdly, the land to the north and west of Chetumal is less densely populated, offering larger contiguous areas for solar farm development without significant displacement of residential or agricultural activities. It's worth noting that while the flat topography of the region is generally favorable for solar installations, care must be taken to avoid areas with significant karst features or cenotes. These geological formations could complicate construction and potentially be damaged by large-scale development. Overall, the areas within a 30 to 50-kilometer radius north and northwest of Chetumal present the most promising opportunities for large-scale solar PV projects. These locations combine favorable topography, reduced environmental sensitivity, and proximity to existing infrastructure, making them well-suited for solar energy development in the region.
