Tucano, Bahia, Brazil represents an excellent location for year-round solar photovoltaic energy generation. Located in the tropical region at coordinates -10.9943, -38.8625, this area benefits from consistent sunlight throughout most of the year, with seasonal variations defined more by wet and dry periods rather than dramatic changes in solar availability.

Solar Energy Output Performance

The solar energy production at Tucano shows strong performance across all seasons. Summer delivers the highest output at 6.49 kWh per day per kW of installed solar capacity, closely matched by spring at 6.50 kWh per day. Even during the lowest production period in winter, the location still generates a respectable 5.00 kWh per day per kW, while autumn produces 5.71 kWh per day per kW. The most productive times for solar generation at this location are spring and summer, when output reaches its peak levels. However, the relatively modest variation between seasons - with winter production being only about 23% lower than peak seasons - demonstrates the location's reliability for consistent solar energy generation throughout the year.

Optimal Panel Installation

For fixed panel installations at Tucano, Bahia, the ideal tilt angle to maximize total year-round solar production is 10 degrees facing North. This optimal angle is calculated by analyzing daily solar elevation angles at this latitude, determining daily optimal panel positioning, and weighting these angles according to photovoltaic potential using solar irradiance data while accounting for Earth's elliptical orbit.

Environmental and Weather Challenges

Several significant environmental factors at Tucano can impact solar energy production and require careful consideration during installation:

• Tropical rainfall and humidity: The wet season brings heavy rains and high humidity levels that can reduce panel efficiency and create maintenance challenges
• Dust and particulate accumulation: Dry periods can lead to significant dust buildup on panel surfaces, substantially reducing energy output
• High temperatures: Intense tropical heat can decrease photovoltaic panel efficiency
• Vegetation growth: Rapid tropical plant growth can create shading issues if not properly managed

Preventative Measures for Optimal Performance

To maximize solar energy production despite these challenges, several preventative measures should be implemented:

• Regular cleaning systems: Install automated panel washing systems or establish frequent manual cleaning schedules to remove dust, dirt, and organic matter
• Proper drainage design: Ensure installations have adequate drainage to prevent water pooling and reduce humidity-related issues
• Ventilation spacing: Mount panels with sufficient air circulation space underneath to help manage heat buildup and improve efficiency
• Vegetation management: Maintain clear zones around installations and implement regular landscaping to prevent shading from growing plants
• Quality mounting systems: Use corrosion-resistant materials suitable for high-humidity tropical environments

Despite these environmental challenges, Tucano's consistent solar resource and strong year-round production potential make it a highly suitable location for solar photovoltaic installations, provided that proper planning and maintenance protocols are implemented to address the tropical climate conditions.

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 Tucano

Seasonal solar PV output for Latitude: -10.9943, Longitude: -38.8625 (Tucano, 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 10° North in Tucano, Brazil

To maximize your solar PV system's energy output in Tucano, Brazil (Lat/Long -10.9943, -38.8625) throughout the year, you should tilt your panels at an angle of 10° 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 Tucano, 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 Tucano, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 10° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
5° South in Summer	16° North in Autumn	26° North in Winter	5° 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 Tucano, 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 Tucano, 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 Tucano, Brazil

Topographical Features Around Tucano

The area surrounding Tucano in Bahia, Brazil is characterized by relatively gentle terrain that forms part of the broader Caatinga ecosystem. This region sits within the São Francisco River valley system, where the landscape consists primarily of rolling hills and modest elevations that rarely exceed 500 meters above sea level. The topography is generally undulating rather than mountainous, creating a series of broad valleys and low ridges that extend across the semi-arid interior of northeastern Brazil. The immediate vicinity of Tucano features predominantly flat to gently sloping terrain, with occasional scattered hills and small escarpments. These geological formations are typical of the crystalline basement rocks that underlie much of the region, which have been weathered over millions of years to create the current subdued relief. The drainage patterns follow natural depressions and valleys, with seasonal watercourses that flow during the rainy periods and remain dry for extended periods throughout the year.

Soil and Surface Conditions

The surface geology around Tucano consists largely of exposed bedrock interspersed with thin soils and areas of accumulated sediment in the valley bottoms. The predominant rock types include granite, gneiss, and schist formations that are part of the Precambrian shield complex. These crystalline rocks create relatively stable foundations across much of the landscape, though they are often covered by a thin veneer of weathered material and scattered vegetation. The soils in this region are generally shallow and well-drained, with low organic content typical of semi-arid environments. Sandy and rocky soils predominate, with patches of clay accumulation in lower-lying areas where water naturally collects during rainfall events. The sparse vegetation cover means that much of the underlying geological structure remains visible or lies just beneath a thin surface layer.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for extensive solar photovoltaic installations would be the broad, gently sloping plateaus and valley floors that extend to the north and east of Tucano. These areas offer several advantages including minimal elevation changes, stable geological foundations, and relatively easy access for construction and maintenance activities. The low-relief terrain minimizes the potential for shading between solar panel arrays and reduces the complexity of site preparation and grading work. Particularly promising areas include the expansive flat zones along the seasonal drainage corridors, where the terrain is naturally level and the substrate consists of consolidated alluvial materials. These locations typically have good load-bearing capacity for supporting large solar installations while maintaining sufficient distance from active water channels to avoid flooding concerns during intense rainfall periods. The elevated plateau areas surrounding the town also present excellent opportunities for solar development. These higher elevations provide natural drainage away from the installation sites while offering expansive areas of relatively uniform topography. The crystalline bedrock underlying these plateau surfaces creates stable foundations that can support heavy infrastructure with minimal settlement concerns. Areas to the southwest of Tucano, where the terrain transitions into broader valley systems, offer particularly attractive conditions for large-scale solar farms. The combination of gentle slopes, minimal vegetation cover, and stable geological conditions creates ideal circumstances for efficient panel placement and optimal energy capture throughout the day.
