Solar Potential in Boa Viagem, Ceará, Brazil

Boa Viagem, Ceará, Brazil offers excellent conditions for solar energy generation throughout the year. Located in the tropics at coordinates -5.0253, -39.8378, this location benefits from consistent sunlight patterns typical of tropical regions, where seasonal variations are primarily defined by wet and dry periods rather than significant changes in daylight duration. The solar electricity production potential at this location shows impressive year-round performance. Spring stands out as the most productive season with 7.00kWh per day for each kilowatt of installed capacity. Winter follows with a solid 6.20kWh/day, while autumn produces 6.05kWh/day. Even summer maintains strong generation at 5.80kWh/day per kilowatt installed. For maximum efficiency with fixed solar panel installations in Boa Viagem, Ceará, panels should be tilted at 5 degrees facing North. This optimal angle has been calculated by analyzing solar elevation patterns at this specific latitude and weighting them according to the location's solar potential throughout the year.

Environmental and Weather Considerations

Despite the excellent solar conditions, several factors may affect solar production in Boa Viagem:
  • Seasonal rainfall patterns could temporarily reduce solar output during the wet season, typically from January to April.
  • Dust accumulation is common in tropical regions with alternating wet and dry seasons, potentially reducing panel efficiency if not regularly maintained.
  • High temperatures in the tropics can slightly decrease panel efficiency, as most solar panels lose efficiency when operating above 25°C.
To maximize solar energy production in this location, several preventative measures are recommended. Installing panels with adequate spacing for airflow can help mitigate temperature-related efficiency losses. Implementing a regular cleaning schedule, especially during dry seasons when dust accumulation is highest, will maintain optimal performance. Additionally, using microinverters or power optimizers can help minimize production losses when some panels are partially shaded or affected by localized weather conditions. The consistent solar potential throughout the year makes Boa Viagem an ideal location for solar PV installations, with proper maintenance practices ensuring optimal energy harvest across all seasons.

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

Ideally tilt fixed solar panels 5° North in Boa Viagem, Brazil

To maximize your solar PV system's energy output in Boa Viagem, Brazil (Lat/Long -5.0253, -39.8378) throughout the year, you should tilt your panels at an angle of 5° 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 Boa Viagem, 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 Boa Viagem, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 5° North tilt angle throughout the year.

Overall Best Summer Angle Overall Best Autumn Angle Overall Best Winter Angle Overall Best Spring Angle
11° South in Summer 11° North in Autumn 21° North in Winter 1° South in Spring

Assuming you can modify the tilt angle of your solar PV panels throughout the year, you can optimize your solar generation in Boa Viagem, Brazil as follows: In Summer, set the angle of your panels to 11° facing South. In Autumn, tilt panels to 11° facing North for maximum generation. During Winter, adjust your solar panels to a 21° angle towards the North for optimal energy production. Lastly, in Spring, position your panels at a 1° angle facing South to capture the most solar energy in Boa Viagem, Brazil.

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.

Topography for solar PV around Boa Viagem, Brazil

Topography of Boa Viagem, Brazil

Boa Viagem, located in the state of Ceará in northeastern Brazil, sits within a region characterized by a diverse topographical profile. The landscape around Boa Viagem features a mix of gently rolling hills, shallow valleys, and relatively flat plains. The terrain gradually rises from the coastal areas of Ceará toward the interior, with Boa Viagem situated in this transitional zone. The municipality lies at an elevation of approximately 270 meters above sea level, in what is known as the "sertão" or semi-arid backlands of Brazil's northeast. This region is part of the larger Borborema Plateau, which dominates much of the interior northeastern Brazil. The topography consists primarily of weathered crystalline basement rocks, creating a landscape of moderate relief with occasional more prominent hills and ridges. Surrounding the immediate area of Boa Viagem are several noteworthy topographical features. To the east, the terrain gradually descends toward the coastal plains of Ceará. To the west and southwest, the landscape becomes more rugged as it transitions toward the foothills of the Ibiapaba Plateau. Numerous seasonal streams and small rivers cut through the landscape, creating shallow valleys that are typically dry during much of the year but can fill rapidly during the rainy season.

Solar PV Potential in the Region

The topographical characteristics of the Boa Viagem region make several nearby areas particularly suitable for large-scale solar photovoltaic (PV) installations. The most promising locations include: The flat to gently sloping plains surrounding the municipality offer ideal conditions for solar PV development. These areas provide large, continuous tracts of land with minimal shading concerns and relatively simple construction requirements. The natural slight incline of many of these plains, often facing northward, provides an optimal orientation for solar panels in the Southern Hemisphere. The elevated plateaus to the west of Boa Viagem present another excellent option for solar PV development. These higher elevation areas often experience less atmospheric interference and dust, potentially increasing solar panel efficiency. The plateaus also typically have sparse vegetation due to the semi-arid climate, reducing land clearing requirements. The transitional zones between the lowlands and higher elevations offer a compromise between accessibility and optimal solar exposure. These areas frequently have good road access while maintaining the favorable solar radiation conditions characteristic of the region. Areas to avoid for solar development include the seasonal watercourses and their immediate surroundings, as these locations may be subject to periodic flooding. Similarly, the more steeply sloped areas would require significant grading work, increasing construction costs and environmental impact. The region's geology, dominated by crystalline rocks with relatively thin soil cover in many areas, provides stable foundation conditions for solar infrastructure. This geological stability, combined with the minimal risk of landslides in the gently sloping areas, enhances the suitability of much of the surrounding landscape for large-scale solar installations.
