Branquinha, Brazil represents an excellent location for year-round solar photovoltaic energy generation. Located in the tropical region at coordinates -9.2096, -36.0913, this area benefits from consistent 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 Branquinha shows strong performance across all seasons. Spring emerges as the peak production period, generating 7.02 kWh per day per kW of installed solar capacity. Summer follows closely with 6.86 kWh/day per kW, making these two seasons the most productive for solar energy generation. Autumn production drops to 5.67 kWh/day per kW, while winter shows the lowest output at 4.87 kWh/day per kW. However, even the winter production levels remain quite respectable for solar generation, demonstrating the location's year-round viability for solar energy projects.Optimal Installation Configuration
For fixed panel installations at Branquinha, the ideal tilt angle to maximize total year-round solar production is 7 degrees North. This relatively shallow angle reflects the location's proximity to the equator and helps optimize energy capture throughout the annual solar cycle.Environmental and Weather Considerations
Several local factors could potentially impact solar production efficiency in Branquinha and require attention during installation planning. The tropical climate brings significant humidity levels throughout much of the year, which can lead to moisture-related issues. High humidity may cause condensation problems in electrical components and can accelerate corrosion of metal mounting systems. Additionally, the combination of heat and humidity creates ideal conditions for mold and algae growth on panel surfaces, which can reduce light transmission and decrease energy output. Branquinha's location in northeastern Brazil means it experiences distinct wet and dry seasons typical of tropical climates. During wet periods, frequent cloud cover can reduce solar irradiance, while heavy rainfall events may cause temporary flooding or drainage issues around ground-mounted installations. The coastal proximity of this region in Alagoas state introduces salt air concerns. Salt spray and airborne salt particles can accumulate on solar panels and mounting hardware, leading to corrosion and reduced panel efficiency over time. Tropical storms and strong wind events, while not as severe as hurricanes, can still pose risks to solar installations through high winds, flying debris, and intense rainfall.Preventative Measures for Enhanced Performance
Several installation strategies can help mitigate these environmental challenges and ensure optimal energy production:- Install panels with adequate spacing and ventilation to promote air circulation and reduce moisture buildup
- Use marine-grade or stainless steel mounting hardware specifically designed to resist salt corrosion
- Apply anti-corrosion coatings to all metal components exposed to the elements
- Design mounting systems to withstand higher wind loads than standard installations
- Ensure proper drainage around ground-mounted systems to prevent water accumulation
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 Branquinha
Seasonal solar PV output for Latitude: -9.2096, Longitude: -36.0913 (Branquinha, 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 7° North in Branquinha, Brazil
To maximize your solar PV system's energy output in Branquinha, Brazil (Lat/Long -9.2096, -36.0913) throughout the year, you should tilt your panels at an angle of 7° 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 Branquinha, 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 Branquinha, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 7° South in Summer | 15° North in Autumn | 25° North in Winter | 3° 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 Branquinha, 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 Branquinha, Brazil.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Branquinha, Brazil
Topographical Features of the Branquinha Region
Branquinha sits within the coastal lowlands of Alagoas state in northeastern Brazil, positioned approximately 50 kilometers inland from the Atlantic Ocean. The terrain in this region is characterized by gently rolling hills and relatively flat plains that form part of the broader Atlantic coastal plain system. Elevations in the immediate vicinity typically range from 200 to 400 meters above sea level, creating a landscape of moderate undulation rather than dramatic elevation changes.
The area features a mix of agricultural lands, pastures, and remnants of Atlantic Forest vegetation. Small streams and seasonal watercourses cut through the landscape, creating shallow valleys and drainage channels that flow generally eastward toward the coast. The topography becomes progressively flatter as one moves closer to the Atlantic, while the terrain rises more noticeably toward the west as it approaches the foothills of the Brazilian Highlands.
The region's geology consists primarily of sedimentary formations and weathered crystalline rocks, which have created soils that support both agriculture and natural vegetation. The landscape shows evidence of human modification through centuries of farming and cattle ranching, with many areas cleared of original forest cover and converted to productive land use.
Optimal Areas for Large-Scale Solar Development
The most promising locations for extensive solar photovoltaic installations lie on the flatter agricultural plains to the east and southeast of Branquinha. These areas offer several advantages including minimal slope gradients, reduced earthwork requirements for installation, and existing access infrastructure developed for agricultural purposes. The relatively open terrain in these zones would minimize shading issues between solar panel arrays and allow for efficient layout designs.
Areas of particular interest include the broader valleys and plains that extend toward the municipalities of Matriz de Camaragibe and ColĂ´nia Leopoldina. These locations combine favorable topographical conditions with proximity to existing electrical transmission infrastructure along major transportation corridors. The gentle slopes in these areas, typically less than 5 degrees, would be ideal for optimizing panel orientation while maintaining cost-effective installation procedures.
The western portions of the region, while receiving similar solar exposure, present more challenging topographical conditions with steeper slopes and more fragmented terrain. However, some elevated plateaus in this direction could serve as secondary development sites, particularly where the terrain levels out into broader mesa-like formations. These elevated areas might offer advantages in terms of reduced atmospheric interference and potential for better wind cooling of solar installations.
Agricultural lands that are currently underutilized or experiencing declining productivity could represent the most practical development opportunities. The existing road network serving these farming areas would facilitate construction access and ongoing maintenance operations for solar facilities. Additionally, the relatively sparse population density in the rural areas surrounding Branquinha would minimize potential conflicts with residential development while providing ample space for large-scale solar arrays.
