Coxim, Mato Grosso do Sul, Brazil represents a highly favorable location for year-round solar photovoltaic energy generation. Located in the tropical region of South America, this area benefits from consistently strong sunlight throughout most of the year, with seasonal variations characterized more by wet and dry periods rather than the dramatic temperature changes seen in temperate climates.

Solar Energy Production Performance

The solar energy output data for Coxim demonstrates excellent year-round performance. Summer delivers the highest production at 6.61 kWh per day per kilowatt of installed solar capacity, while spring follows closely with 6.39 kWh per day per kW. Autumn maintains strong output at 5.88 kWh per day per kW, and even winter—the lowest production season—still generates a respectable 5.34 kWh per day per kW. This relatively modest seasonal variation indicates that Coxim is an ideal location for consistent solar energy generation throughout the year. The difference between the highest and lowest producing seasons is only about 1.3 kWh per day per kW, demonstrating remarkable stability compared to locations at higher latitudes. For optimal year-round energy production, solar panels should be installed at a fixed tilt angle of 17 degrees facing north. This angle maximizes total annual solar output by accounting for the sun's varying position throughout the year and the location's specific latitude.

Environmental and Weather Challenges

Despite the excellent solar potential, several local factors could impact solar energy production in Coxim:

• Tropical rainfall patterns: The wet season brings heavy rains and increased cloud cover, which can reduce solar irradiance and affect panel performance
• High humidity levels: Persistent moisture in the air can lead to reduced panel efficiency and potential corrosion of equipment
• Dust and particulate accumulation: Dry season conditions can result in dust buildup on panel surfaces, reducing light transmission
• Vegetation growth: The tropical climate promotes rapid plant growth that could create shading issues if not properly managed

Preventative Measures for Optimal Performance

To maximize solar energy production in Coxim's tropical environment, several installation and maintenance strategies should be implemented: Regular cleaning schedules become essential, particularly during the dry season when dust accumulation is most problematic. Installing panels with adequate spacing allows for proper air circulation, which helps reduce moisture-related issues and improves cooling efficiency. Choosing corrosion-resistant mounting hardware and electrical components designed for high-humidity environments will ensure long-term system reliability. Anti-corrosive coatings on metal components provide additional protection against the tropical climate. Proper drainage systems around the installation site prevent water accumulation during heavy rains, while strategic vegetation management maintains clear sight lines to the sun throughout the year. Installing monitoring systems allows for quick identification of performance issues related to weather or environmental factors. The selection of high-quality panels with good low-light performance helps maintain energy production during cloudy periods common in the wet season. Additionally, ensuring adequate ventilation behind panels prevents overheating, which can reduce efficiency in the consistently warm tropical climate.

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 Coxim

Seasonal solar PV output for Latitude: -18.2126, Longitude: -54.717 (Coxim, Brazil), 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° North in Coxim, Brazil

To maximize your solar PV system's energy output in Coxim, Brazil (Lat/Long -18.2126, -54.717) throughout the year, you should tilt your panels at an angle of 17° North 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 Coxim, Brazil

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 Coxim, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 17° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
3° North in Summer	24° North in Autumn	34° North in Winter	12° North 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 Coxim, Brazil

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 Coxim, Brazil

Topography Around Coxim

Coxim sits in the heart of Brazil's Mato Grosso do Sul state, positioned within the expansive Pantanal region that characterizes much of this area. The landscape surrounding the city is predominantly flat to gently rolling, with elevations typically ranging between 200 and 400 meters above sea level. This relatively modest elevation places Coxim on what geographers call the Brazilian Central Plateau, a vast highland area that forms the backbone of the country's interior.

The terrain immediately around Coxim features broad, open plains interspersed with low hills and gentle ridges. These undulating grasslands, known locally as cerrado, stretch for kilometers in all directions, broken occasionally by gallery forests that follow the meandering watercourses. The Taquari River flows near the city, creating a network of floodplains and wetlands that are part of the greater Pantanal ecosystem.

During the wet season, much of the lower-lying land around Coxim becomes seasonally flooded, transforming vast areas into temporary wetlands. This natural flooding cycle creates a distinctive landscape where slightly elevated areas remain dry while surrounding depressions fill with water. The result is a patchwork of islands, peninsulas, and temporary lakes that can persist for several months each year.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations around Coxim would be the elevated areas that remain above the seasonal flood line. These higher ground locations, typically found on the gentle hills and ridges scattered throughout the region, offer several advantages for solar development. The slightly elevated terrain ensures year-round accessibility and protects equipment from the annual flooding that affects lower elevations.

The rolling hills to the north and east of Coxim present particularly promising opportunities for solar farms. These areas combine sufficient elevation to avoid flooding with relatively gentle slopes that minimize construction challenges and maximize solar panel efficiency. The open nature of the cerrado landscape in these locations means minimal tree clearing would be required, reducing environmental impact and development costs.

Areas with southern-facing slopes would be especially valuable, as they can capture maximum solar exposure throughout the day. The consistent topography of these elevated zones allows for efficient layout of solar arrays in regular patterns, optimizing both land use and maintenance access. The firm, well-drained soils found on these higher elevations also provide stable foundations for solar mounting systems.

Transportation access represents another crucial factor in site selection around Coxim. The elevated areas near existing roads, particularly those connecting to the BR-163 highway system, would significantly reduce infrastructure development costs. These locations combine the topographical advantages of higher elevation with practical benefits of existing access routes, making them prime candidates for large-scale solar installations in the region.
