Solar Energy Potential at Teixeira de Freitas, Brazil

Teixeira de Freitas, Brazil, situated in the tropical region at latitude -17.5321 and longitude -39.738, presents generally favorable conditions for solar energy production throughout the year. Being located in the tropics, this area benefits from relatively consistent sunlight patterns compared to locations at higher latitudes. The solar energy production potential shows moderate seasonal variation. During summer months, solar panels can generate approximately 5.97 kWh per day for each kilowatt of installed capacity, representing the peak production period. Autumn follows closely with 5.66 kWh/day, while spring delivers a similar output at 5.51 kWh/day. Winter shows the lowest production at 4.54 kWh/day, though this reduction is less dramatic than in non-tropical regions. For fixed solar panel installations in Teixeira de Freitas, the ideal tilt angle to maximize year-round energy production is 16 degrees facing North. This specific angle optimizes solar capture across seasonal variations, accounting for the Earth's elliptical orbit and the site's particular location in the southern hemisphere.

Environmental and Weather Considerations

Several environmental factors could potentially affect solar production efficiency in Teixeira de Freitas:

• High humidity and rainfall during wet seasons may reduce panel efficiency and increase the need for maintenance
• Dust accumulation from nearby agricultural activities can diminish panel performance if not regularly cleaned
• Coastal proximity may expose installations to salt spray, potentially accelerating corrosion of mounting hardware
• Occasional tropical storms could pose physical risks to installations if not properly secured

To mitigate these challenges, solar installations should incorporate corrosion-resistant materials suitable for tropical coastal environments. Regular cleaning schedules should be implemented, particularly during dry seasons when dust accumulation is highest. Mounting systems should be designed to withstand tropical storm conditions, and slightly increasing the tilt angle beyond the optimal 16 degrees may help with natural cleaning during rainfall events. The relatively small seasonal variation in solar output makes Teixeira de Freitas suitable for year-round solar energy production, with only modest battery storage requirements to compensate for the winter reduction in output. Overall, with appropriate design considerations for the local tropical conditions, this location presents a favorable setting for solar PV installations.

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

Ideally tilt fixed solar panels 16° North in Teixeira De Freitas, Brazil

To maximize your solar PV system's energy output in Teixeira De Freitas, Brazil (Lat/Long -17.5321, -39.738) throughout the year, you should tilt your panels at an angle of 16° 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 Teixeira De Freitas, 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 Teixeira De Freitas, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 16° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
2° North in Summer	23° North in Autumn	33° North in Winter	11° 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 Teixeira De Freitas, 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 Teixeira De Freitas, 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 Teixeira De Freitas, Brazil

The region surrounding Teixeira de Freitas in Bahia, Brazil, features a diverse topographical landscape characterized by gently rolling hills, plateaus, and coastal lowlands. Located approximately 40 kilometers inland from the Atlantic Ocean, this area sits at the transition between Brazil's eastern coastal plains and the more elevated interior highlands.

Topographical Features

The immediate vicinity of Teixeira de Freitas presents a moderately undulating terrain with elevations generally ranging between 80 and 200 meters above sea level. The landscape gradually rises as one moves westward, forming part of the eastern Brazilian plateau system. These elevated areas feature scattered hills interspersed with flatter sections and shallow valleys carved by local river systems. To the east, the terrain gradually descends toward the Atlantic coastline, transitioning into coastal plains. Several river valleys cut through the region, including the Rio Itanhém (also known as Rio Alcobaça) which flows eastward toward the ocean. These waterways have shaped the local topography, creating natural drainage pathways and contributing to the undulating character of the landscape. The region's natural vegetation consists primarily of Atlantic Forest remnants and transitional zones between forest and savanna ecosystems, though much of the original vegetation has been modified by agricultural activities, particularly eucalyptus plantations and cattle ranching.

Solar PV Potential Areas

Several characteristics make certain areas near Teixeira de Freitas particularly promising for large-scale solar photovoltaic development: The elevated plateau regions to the west and northwest of Teixeira de Freitas offer excellent potential for solar installations. These areas benefit from relatively flat terrain at higher elevations, reducing shadowing effects and maximizing solar exposure throughout the day. The stable geological foundation also provides good conditions for mounting solar array infrastructure. The gently rolling agricultural lands surrounding the city, particularly those currently used for extensive farming or eucalyptus plantations, represent prime candidates for solar development. These areas typically have already been cleared of dense vegetation, have established access roads, and feature terrain that requires minimal grading for solar installation. The transitional zones between the coastal plains and the inland plateaus offer a compromise between accessibility and optimal solar conditions. These areas generally have good infrastructure connections while maintaining favorable topographical characteristics for solar arrays. Areas to avoid include the steeper hillsides found in some parts of the region, riverine valleys subject to flooding, and locations with dense remaining forest coverage that would require significant clearing. Additionally, the immediate coastal lowlands, while flat, may be subject to higher humidity levels and occasional coastal weather events that could impact solar performance. The region's climate complements its topographical advantages, with minimal seasonal variation in temperature and a favorable balance between clear skies and precipitation. The combination of these factors creates numerous viable locations for large-scale solar PV development within a 50-kilometer radius of Teixeira de Freitas.
