Tanquinho, Bahia, Brazil is located in an excellent position for year-round solar energy generation. This tropical location benefits from consistent sunlight throughout most of the year, with seasonal variations primarily driven by wet and dry periods rather than the dramatic temperature and daylight changes seen in temperate regions.

Solar Energy Performance

The solar energy output at Tanquinho shows strong performance across most seasons. Summer delivers the highest production at 6.33kWh per day per kW of installed solar capacity, while spring follows closely at 6.27kWh/day. Autumn maintains solid output at 6.04kWh/day, though winter shows a notable decrease to 4.70kWh/day per kW installed. For optimal year-round energy production, solar panels should be installed at a fixed tilt angle of 11 degrees facing north. This angle is calculated to maximize total annual solar output by accounting for the sun's position throughout the year and weighting these angles based on solar irradiance data.

Ideal Generation Periods

The best times for solar generation at this location are during summer and spring months, when output exceeds 6.2kWh/day per kW. While winter shows reduced performance, the location still maintains reasonable solar production even during this lower-output season.

Environmental Challenges and Solutions

Several local factors could potentially impact solar energy production at Tanquinho:

• Tropical humidity and moisture: High humidity levels can create condensation on panels and promote corrosion of electrical components
• Heavy rainfall during wet seasons: While rain can help clean panels, intense tropical downpours may reduce generation during storms
• Dust and debris accumulation: Dry seasons may lead to dust buildup on panel surfaces
• Salt air exposure: Depending on proximity to the coast, salt corrosion could affect equipment

To maximize energy production despite these challenges, several preventative measures should be implemented. Installing panels with robust weatherproof sealing and using marine-grade electrical components can help resist moisture and corrosion. Regular cleaning schedules become particularly important during dry periods to remove dust accumulation. Proper drainage around the installation site prevents water pooling that could damage ground-mounted systems. Additionally, using panels with anti-reflective coatings designed for tropical climates can maintain efficiency even when humidity levels are high. Ensuring adequate ventilation behind panels helps prevent overheating and moisture buildup that could reduce performance over time.

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 Tanquinho

Seasonal solar PV output for Latitude: -11.9568, Longitude: -39.0937 (Tanquinho, 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 11° North in Tanquinho, Brazil

To maximize your solar PV system's energy output in Tanquinho, Brazil (Lat/Long -11.9568, -39.0937) throughout the year, you should tilt your panels at an angle of 11° 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 Tanquinho, 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 Tanquinho, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 11° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
3° South in Summer	18° North in Autumn	27° North in Winter	6° 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 Tanquinho, 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 Tanquinho, 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 Tanquinho, Brazil

Topography Around Tanquinho

Tanquinho is located in the state of Bahia in northeastern Brazil, positioned within the Caatinga biome region. The topography surrounding this area is characterized by gently rolling hills and relatively modest elevation changes typical of the Brazilian interior. The landscape consists primarily of low-lying plateaus and undulating terrain, with elevations generally ranging from 200 to 400 meters above sea level.

The region features a semi-arid climate with distinctive dry and wet seasons. The terrain is marked by scattered rock outcroppings and areas of exposed bedrock, which are common throughout this part of Bahia. Small valleys and depressions dot the landscape, often serving as natural drainage channels during the rainy season. The soil composition varies from sandy to clay-based, with areas of lateritic soils that have developed under the region's climatic conditions.

Vegetation in the surrounding area is predominantly Caatinga scrubland, consisting of drought-resistant shrubs, cacti, and small trees that shed their leaves during dry periods. This sparse vegetation cover means that much of the landscape remains relatively open, with clear sightlines across the gently sloping terrain.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations around Tanquinho would be the elevated plateau areas and gentle south-facing slopes that offer consistent exposure to sunlight throughout the day. These elevated positions provide natural advantages in terms of reduced shading and improved air circulation, which helps maintain optimal panel temperatures.

Areas with minimal vegetation cover and stable, well-drained soils present the best opportunities for development. The relatively flat to gently sloping terrain reduces the need for extensive grading and earthwork, making construction more cost-effective. Locations with existing road access or proximity to transportation corridors would be particularly advantageous for equipment delivery and maintenance operations.

The scattered rock outcroppings, while potentially challenging for construction, can actually provide stable foundation options for mounting systems. Areas between these rocky formations often feature compacted soils suitable for ground-mounted solar arrays. The natural drainage patterns should be considered to avoid low-lying areas that might experience seasonal flooding or water accumulation.

Sites located on the higher elevations within a 10-20 kilometer radius of Tanquinho would likely offer the best combination of accessibility, stable terrain, and minimal environmental constraints. These locations benefit from the region's clear atmospheric conditions while avoiding the complications associated with steeper slopes or densely vegetated areas that would require significant clearing operations.
