Presidente Tancredo Neves, Bahia, Brazil, located in the tropics at latitude -13.4615 and longitude -39.4213, offers promising conditions for solar energy generation throughout the year. This location benefits from the tropical climate where sunlight remains relatively consistent, with seasonal variations primarily defined by wet and dry periods rather than significant changes in daylight duration.

Seasonal Solar Production

The solar energy potential at this location shows favorable output across all seasons:

• Summer: 5.76 kWh per day for each kW of installed capacity
• Autumn: 5.90 kWh per day for each kW of installed capacity
• Winter: 4.73 kWh per day for each kW of installed capacity
• Spring: 5.92 kWh per day for each kW of installed capacity

This data reveals that spring and autumn are the most productive seasons for solar generation in Presidente Tancredo Neves, Bahia, with winter showing a moderate decrease in output but still maintaining reasonable production levels. The relatively small variation between seasons indicates a dependable year-round solar resource.

Optimal Panel Installation

For fixed solar panel installations in Presidente Tancredo Neves, Bahia, the ideal tilt angle to maximize year-round energy production is 13 degrees facing North. This specific angle has been calculated to optimize solar collection throughout the year, accounting for the Earth's elliptical orbit and the site's tropical location.

Environmental and Weather Considerations

Several environmental factors could potentially affect solar production in this tropical location: Rainfall and humidity during the wet season may temporarily reduce solar output due to cloud cover. Installing panels with anti-reflective coatings can help maximize energy capture even in diffuse light conditions during cloudy periods. High temperatures in the tropics can slightly reduce solar panel efficiency. Ensuring adequate airflow beneath panels through proper mounting systems can mitigate this effect by allowing heat dissipation. Dust accumulation is another consideration in tropical environments, particularly during dry seasons. Implementing a regular cleaning schedule or installing automated cleaning systems can prevent significant production losses from soiling. Potential vegetation growth in this tropical region might cast shadows on panels if not properly managed. Regular maintenance of the surrounding area to prevent overgrowth is recommended. Overall, Presidente Tancredo Neves offers excellent conditions for solar energy production with relatively minor seasonal variations, making it a promising location for photovoltaic installations when proper installation techniques and maintenance practices are employed.

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

Ideally tilt fixed solar panels 13° North in Presidente Tancredo Neves, Brazil

To maximize your solar PV system's energy output in Presidente Tancredo Neves, Brazil (Lat/Long -13.4615, -39.4213) throughout the year, you should tilt your panels at an angle of 13° 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 Presidente Tancredo Neves, 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 Presidente Tancredo Neves, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 13° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
2° South in Summer	19° North in Autumn	29° North in Winter	8° 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.

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 Presidente Tancredo Neves, Brazil

The region surrounding Presidente Tancredo Neves in Bahia, Brazil presents a varied topographical landscape characterized by rolling hills, shallow valleys, and modest plateaus. Located in the Atlantic Forest biome, the terrain features gentle to moderate elevations with some areas reaching between 200-400 meters above sea level. The landscape is dissected by numerous small rivers and streams that have carved shallow valleys throughout the region, creating a somewhat undulating profile rather than steep mountainous terrain. The natural vegetation consists of tropical and subtropical moist broadleaf forests, though significant portions have been converted to agricultural use, particularly for cacao plantations and other crops suited to the region's climate. This agricultural conversion has modified the original topography in many areas, creating a patchwork of cleared lands and remaining forest fragments.

Solar PV Potential Areas

For large-scale solar photovoltaic installations, several areas in the vicinity of Presidente Tancredo Neves show promising characteristics. The most suitable locations would be the elevated plateaus and gently sloping hillsides that face northward (in the Southern Hemisphere, north-facing slopes receive more direct sunlight). These areas typically have reduced vegetation cover and better exposure to solar radiation throughout the day. The cleared agricultural lands on higher ground present particularly favorable conditions for solar development. These sites often have the advantage of existing access roads, reduced flooding risk, and minimal shading from surrounding terrain features. The relatively flat hilltops scattered throughout the region would require less grading and preparation work compared to steeper terrain, reducing installation costs and environmental impact. Areas to avoid would include the lower-lying river valleys which may be subject to seasonal flooding and have higher humidity levels that can affect solar panel efficiency. Similarly, the remaining dense forest areas would require extensive clearing, creating both environmental concerns and additional development costs. The southwestern portions of the municipality generally feature more consistent elevation profiles with broader plateaus that could accommodate larger, contiguous solar arrays. These areas would minimize the fragmentation of installations while maximizing land use efficiency for solar energy production.
