Miranda, Mato Grosso do Sul, Brazil, situated in the tropical region at latitude -20.2129 and longitude -56.5265, offers a promising location for solar PV energy generation throughout the year. This location benefits from the consistent tropical sunlight pattern, where seasonal variations are primarily defined by wet and dry periods rather than significant daylight duration changes.

Seasonal Solar Production

Solar energy production in Miranda shows notable seasonal variations despite its tropical location. Summer months yield the highest energy output at 6.84kWh per day for each kilowatt of installed capacity. Spring follows closely with 6.18kWh/day, while autumn produces a moderate 5.54kWh/day. Winter represents the least productive season with 4.57kWh/day, though this output still remains relatively substantial compared to non-tropical locations.

The difference between the most productive summer months and least productive winter period is approximately 33%, indicating a reasonably consistent year-round production profile that makes Miranda suitable for solar investments with predictable returns throughout the year.

Optimal Panel Installation

For fixed solar panel installations in Miranda, Mato Grosso do Sul, the ideal tilt angle to maximize year-round energy production is 18 degrees facing North. This specific angle has been calculated to optimize solar capture across seasonal variations, accounting for the Earth's elliptical orbit and the location's position south of the equator.

Environmental and Weather Considerations

Several environmental factors could potentially impact solar production efficiency in Miranda:

• Seasonal heavy rainfall during the wet season may reduce solar efficiency through cloud cover and direct panel soiling
• High humidity levels typical of tropical regions can cause accelerated degradation of electrical components if not properly protected
• Potential dust accumulation during the dry season can gradually decrease panel efficiency
• Higher than average temperatures may slightly reduce photovoltaic conversion efficiency

Preventative Measures

To mitigate these environmental challenges and maximize solar production, several installation strategies are recommended:

Installing panels with adequate elevation and tilt helps facilitate natural cleaning during rainfall events. Implementing regular cleaning schedules, particularly during the dry season, prevents dust and debris accumulation. Using humidity-resistant components and proper enclosures for inverters and electrical connections prevents premature degradation in the tropical climate.

Additionally, ensuring proper ventilation behind panels helps mitigate temperature-related efficiency losses. Some installations may benefit from automated cleaning systems in this location, especially for larger commercial applications where manual cleaning becomes impractical.

With these considerations addressed through proper design and maintenance protocols, Miranda presents an excellent location for solar PV installations with strong year-round production 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 Miranda

Seasonal solar PV output for Latitude: -20.2129, Longitude: -56.5265 (Miranda, 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 18° North in Miranda, Brazil

To maximize your solar PV system's energy output in Miranda, Brazil (Lat/Long -20.2129, -56.5265) throughout the year, you should tilt your panels at an angle of 18° 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 Miranda, 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 Miranda, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 18° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
4° North in Summer	26° North in Autumn	35° North in Winter	14° 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 Miranda, Brazil

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 Miranda, 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 Miranda, Brazil

The topography around Miranda in Brazil is characterized predominantly by the vast, low-lying wetlands of the Pantanal, one of the world's largest tropical wetland systems. Miranda sits at the western edge of Mato Grosso do Sul state, where the landscape transitions between the Pantanal floodplains and more elevated terrain. In this region, the elevation generally ranges from approximately 100 to 200 meters above sea level. The Pantanal itself is notably flat with minimal elevation changes across large distances, which creates the distinctive seasonal flooding pattern the area is known for. During wet seasons, much of the surrounding landscape becomes inundated, forming a complex mosaic of permanent and temporary wetlands, channels, and isolated patches of higher ground.

Surrounding Terrain Features

To the east of Miranda, the terrain gradually rises toward the Brazilian Plateau (Planalto), with some hills and more pronounced topographic relief. This eastern transition zone features scattered limestone outcrops and residual hills that punctuate the otherwise level landscape. The Miranda River, a tributary of the Paraguay River system, meanders through the region, further defining the local topography with its floodplain. The western areas near Miranda remain predominantly flat, continuing into the heart of the Pantanal wetland complex. Some isolated elevations known locally as "cordilheiras" (forest-covered ridges) and "capões" (rounded elevations) rise just a few meters above the floodplain, creating islands of higher ground that remain dry even during flood periods.

Potential Areas for Solar PV Development

For large-scale solar photovoltaic development, the most suitable areas near Miranda would be the non-flooding elevated terrains to the east and northeast of the city. These areas offer several advantages for solar installations: The slightly elevated plateaus and higher ground transitioning toward the Brazilian Plateau provide stable, dry land that isn't subject to the seasonal flooding that affects much of the Pantanal. This terrain stability is crucial for long-term infrastructure investments like solar farms. Areas with gentle slopes facing north maximize solar exposure in the Southern Hemisphere. The gradual rise in elevation moving east from Miranda creates some terrain with favorable orientation for solar collection efficiency. The relatively open vegetation patterns in the transition zones between the Pantanal and the Cerrado (Brazilian savanna) to the east provide naturally cleared areas that would require minimal vegetation removal for solar installation, reducing environmental impact and site preparation costs. The non-flooding areas also offer better accessibility for construction and maintenance, with more stable road conditions throughout the year compared to the wetland regions. It's worth noting that while the immediate Pantanal wetlands themselves are less suitable for large-scale solar development due to flooding concerns and ecological sensitivity, the transitional landscapes where Miranda is situated provide interesting opportunities for renewable energy development that could balance energy production needs with environmental conservation priorities.
