Solar Energy Potential in Barra do Bugres, Brazil

Barra do Bugres, Brazil, situated at latitude -15.0858 and longitude -57.526, offers promising conditions for solar energy generation throughout the year. This tropical location benefits from relatively consistent sunlight patterns that make it suitable for photovoltaic (PV) installations. The seasonal energy production at this location shows remarkable consistency. During summer months, solar panels can generate approximately 6.17 kWh per day for each kilowatt of installed capacity. This drops slightly to 5.56 kWh/day in autumn and 5.53 kWh/day in winter, before rising again to 5.88 kWh/day in spring. This minimal seasonal variation (only about 10% difference between highest and lowest production) is a significant advantage compared to locations at higher latitudes. For fixed solar panel installations in Barra do Bugres, the ideal tilt angle to maximize year-round energy production is 15 degrees facing North. This specific angle optimizes solar capture throughout the year, accounting for the location's position south of the equator and the earth's elliptical orbit.

Environmental and Weather Considerations

Several environmental factors may affect solar production in Barra do Bugres:

• Heavy rainfall during the wet season can temporarily reduce solar output and may cause dirt accumulation on panels
• High humidity levels can slightly decrease panel efficiency
• Potential dust accumulation during the dry season
• Occasional cloud cover during the rainy season

To mitigate these challenges, several preventative measures can be implemented: Regular panel cleaning is essential, particularly after the dry season when dust accumulation is highest. Installing panels at the recommended 15-degree tilt not only optimizes sunlight capture but also facilitates natural cleaning during rainfall. Additionally, using high-quality inverters with good performance in high-temperature environments will help maintain efficiency during the hottest periods. Despite these minor challenges, Barra do Bugres remains an excellent location for solar energy production with its consistent year-round solar resource and relatively minimal seasonal variation.

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

Ideally tilt fixed solar panels 15° North in Barra Do Bugres, Brazil

To maximize your solar PV system's energy output in Barra Do Bugres, Brazil (Lat/Long -15.0858, -57.526) throughout the year, you should tilt your panels at an angle of 15° 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 Barra Do Bugres, 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 Barra Do Bugres, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 15° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
1° South in Summer	21° North in Autumn	31° North in Winter	9° 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 Barra Do Bugres, 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 Barra Do Bugres, 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 Barra Do Bugres, Brazil

The terrain surrounding Barra do Bugres in Mato Grosso state, Brazil, presents a diverse topographical landscape characterized by a transition zone between the Amazon Basin and the Brazilian Plateau. The municipality sits at approximately 160 meters above sea level along the banks of the Bugres River, a tributary of the Paraguay River. This location places it at the edge of the Pantanal wetland system, with the landscape gradually rising toward the east and north. The immediate vicinity of Barra do Bugres features gently rolling hills interspersed with flat plains, particularly along the river valleys. Moving eastward, the terrain becomes more undulating with elevations increasing to form part of the Brazilian Shield, an ancient geological formation. The western areas transition toward the Pantanal lowlands, creating a more gradual, flatter topography with occasional wetland features during rainy seasons.

Topographical Features

The region exhibits several distinct topographical zones. The riverine areas along the Bugres and Paraguay rivers form alluvial plains with fertile soil deposits. These lower-lying areas occasionally experience seasonal flooding, particularly during the wet season between November and March. Beyond these floodplains, the landscape rises into terraced plateaus and hills covered predominantly with cerrado vegetation—a savanna-like ecosystem with scattered trees and shrubs. The northern portions of the municipality feature more pronounced relief with hills reaching elevations of 300-400 meters. These higher areas form part of the southern edge of the Amazon plateau, creating a natural boundary between ecosystems. The soil composition varies considerably across these different topographical zones, ranging from sandy riverine deposits to clay-rich soils in the upland areas.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic installations, several areas around Barra do Bugres offer favorable conditions. The most suitable locations would be the elevated plateaus and gently sloping hillsides to the east and northeast of the municipality. These areas benefit from several advantageous characteristics: The elevated terrains east of Barra do Bugres, particularly those between 200-350 meters above sea level, provide excellent exposure to solar radiation throughout the year. These plateaus typically feature less vegetation obstruction and reduced atmospheric interference compared to lower-lying areas. The northern upland regions, where the landscape transitions toward the Amazon plateau, offer extensive flat or gently sloping terrain that would minimize grading and preparation costs for large installations. These areas typically remain above flood levels even during intense rainfall periods, ensuring operational continuity. Areas approximately 15-30 kilometers east of the urban center present an optimal combination of favorable topography, accessibility via existing road networks, and proximity to transmission infrastructure. The cerrado vegetation in these zones is less dense than forest areas, reducing clearing requirements and associated environmental impacts. The southeastern quadrant of the municipality features some of the most promising terrain for solar development, with well-drained soils on stable geological formations. These areas experience less cloud cover during the wet season compared to the western lowlands, where morning fog and humidity can be more persistent. It's worth noting that while the western lowlands toward the Pantanal have abundant flat terrain, their susceptibility to seasonal flooding and higher humidity levels makes them less ideal for solar PV infrastructure. Similarly, the steeper slopes found in some northern portions would require more extensive site preparation, potentially increasing development costs.
