Macaubal, São Paulo, Brazil represents a very good location for year-round solar energy generation, with its tropical climate providing consistent sunlight throughout most of the year. Located at coordinates -20.86, -49.986, this area benefits from the typical tropical pattern where seasons are characterized more by wet and dry periods rather than dramatic temperature variations.

Solar Energy Production Throughout the Year

The solar energy output at Macaubal shows strong performance across all seasons, though with some seasonal variation:

• Summer delivers the highest output at 7.01 kWh per day per kW of installed solar capacity
• Spring provides excellent production at 6.50 kWh per day per kW
• Autumn maintains good levels at 5.80 kWh per day per kW
• Winter shows the lowest but still respectable output at 5.16 kWh per day per kW

The ideal times for solar generation are clearly summer and spring, when output exceeds 6.5 kWh daily per installed kW. However, even during the winter months, the location maintains over 5 kWh daily production, demonstrating the consistency that makes tropical locations attractive for solar installations.

Optimal Panel Installation

For maximum year-round energy production at Macaubal, São Paulo, solar panels should be installed at a fixed tilt angle of 19 degrees facing North. This angle has been calculated to optimize total annual solar output by accounting for the sun's path throughout the year and weighting for daily solar potential.

Environmental and Weather Challenges

Several local factors could potentially impact solar energy production at this tropical location. The most significant concern is the wet season, which brings increased cloud cover and frequent rainfall that can reduce solar irradiance and require regular panel cleaning to remove accumulated dirt and debris. High humidity levels common in tropical climates can accelerate corrosion of metal components and electrical connections if not properly protected. The combination of heat and moisture also creates ideal conditions for vegetation growth, which could shade panels if not properly managed through regular maintenance.

Preventative Measures for Optimal Performance

To ensure maximum energy production, several preventative measures should be implemented during installation and ongoing maintenance:

• Install panels with adequate spacing and ventilation to prevent overheating and allow air circulation
• Use corrosion-resistant materials and proper sealing for all electrical components
• Implement a regular cleaning schedule to remove dirt, pollen, and organic matter that accumulates more rapidly in humid tropical conditions
• Establish vegetation management around the installation site to prevent shading from fast-growing tropical plants
• Consider drainage solutions to prevent water pooling around ground-mounted systems during heavy rains

Despite these considerations, Macaubal's consistent solar resource makes it well-suited for solar energy generation, with proper installation and maintenance practices ensuring reliable performance throughout the year.

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 Macaubal

Seasonal solar PV output for Latitude: -20.86, Longitude: -49.986 (Macaubal, 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 19° North in Macaubal, Brazil

To maximize your solar PV system's energy output in Macaubal, Brazil (Lat/Long -20.86, -49.986) throughout the year, you should tilt your panels at an angle of 19° 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 Macaubal, 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 Macaubal, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 19° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
5° North in Summer	27° North in Autumn	36° 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 Macaubal, 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 Macaubal, 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 Macaubal, Brazil

Topography Around Macaubal, Brazil

Macaubal sits in the northwestern region of São Paulo state, positioned within the broader landscape of Brazil's southeastern plateau region. The terrain around this area is characterized by gently rolling hills and relatively modest elevation changes, typical of the interior portions of São Paulo state. The landscape consists primarily of agricultural plains interspersed with low ridges and shallow valleys that have been shaped by centuries of erosion and weathering.

The elevation in and around Macaubal ranges from approximately 400 to 600 meters above sea level, with the town itself positioned on relatively flat to gently sloping terrain. The topography becomes more varied as one moves away from the immediate vicinity, with broader undulations becoming more pronounced toward the east and northeast. These elevation changes are gradual rather than dramatic, creating a landscape that appears almost wave-like when viewed from elevated positions.

The region's geology consists primarily of sedimentary formations overlain by rich soils that have made this area highly suitable for agriculture. The terrain has been significantly modified by human activity, with much of the original cerrado vegetation cleared for farming and cattle ranching. This has resulted in large expanses of relatively flat, open land with minimal tree cover across much of the surrounding area.

Water Features and Drainage

The drainage patterns around Macaubal are dominated by small streams and seasonal watercourses that flow generally westward toward the Paraná River system. These waterways have carved shallow valleys through the landscape, creating gentle depressions that are typically no more than 20 to 30 meters below the surrounding terrain. During the wet season, these areas can become temporarily flooded, while in the dry season many of the smaller watercourses may reduce to a trickle or dry up entirely.

Several small reservoirs and farm ponds dot the landscape, created primarily for agricultural irrigation and livestock watering. These water features are generally small and would not pose significant obstacles to large-scale development projects, though they do create localized variations in the otherwise relatively uniform topography.

Most Suitable Areas for Large-Scale Solar Development

The terrain immediately surrounding Macaubal offers excellent potential for large-scale solar photovoltaic installations due to its favorable topographic characteristics. The most promising areas lie to the south and southwest of the town, where extensive flat to gently rolling agricultural land provides ideal conditions for solar array deployment. These areas feature minimal slope variations, which would reduce grading and site preparation costs while maximizing the efficiency of panel placement.

The elevated plateau areas to the northeast and east of Macaubal also present strong opportunities for solar development. While these locations feature slightly more topographic variation, the broader ridgetops and gentle south-facing slopes would be well-suited to solar installations. The elevated positions would provide excellent exposure while the stable geological conditions would support large-scale infrastructure development.

Agricultural areas that have been cleared and maintained as pasture or cropland represent particularly attractive sites for solar development. These locations already have established access routes and electrical infrastructure connections, while the existing land use patterns demonstrate the terrain's stability and suitability for development. The relatively uniform elevation across these agricultural zones would allow for standardized mounting systems and simplified electrical layouts across large installations.

Areas to avoid for large-scale solar development include the immediate vicinity of watercourses and their associated floodplains, which may experience seasonal flooding or have unstable soils. Additionally, the few remaining areas of native vegetation on steeper slopes would be less suitable due to both environmental considerations and the increased complexity of installation on more challenging terrain.
