Solar Energy Potential in Cafarnaum, Bahia, Brazil

Cafarnaum, Bahia, Brazil, located at latitude -11.8067 and longitude -41.384 in the tropical region, offers excellent year-round potential for solar PV energy generation. This location benefits from the consistent sunlight typical of tropical regions, where seasonal changes are primarily characterized by wet and dry periods rather than significant variations in daylight hours. The solar energy production potential remains strong throughout the year, with some seasonal variations. Spring stands out as the most productive season, generating approximately 6.96 kWh per day for each kilowatt of installed solar capacity. Summer follows closely with 6.39 kWh/day, while autumn maintains similar output levels at 6.35 kWh/day. Winter shows a slight decrease but still delivers a respectable 5.61 kWh/day per kilowatt installed. For fixed solar panel installations in Cafarnaum, Bahia, the ideal tilt angle to maximize year-round energy production is 11 degrees facing North. This specific angle has been calculated to optimize solar capture throughout the year, accounting for the location's proximity to the equator and the sun's seasonal path variations.

Environmental and Weather Considerations

Several environmental factors could potentially impact solar production in Cafarnaum:

• Dust and soil accumulation: The region's dry seasons can lead to increased airborne dust that settles on panels, reducing efficiency. Regular cleaning maintenance is recommended, potentially with automated systems during extended dry periods.
• Seasonal rainfall: During wet seasons, cloud cover may temporarily reduce solar output. However, the rain itself helps clean panels naturally, which can partially offset production losses.
• High temperatures: Tropical heat can slightly reduce panel efficiency. Installing panels with adequate air circulation underneath and using temperature-resistant models will help maintain optimal performance.

Preventative measures for installation should include raising panels sufficiently above ground level to minimize dust accumulation, implementing proper drainage systems to handle seasonal heavy rains, and selecting heat-resistant panel technologies specifically designed for tropical climates. Additionally, a slight increase in the installed capacity can compensate for the minor seasonal variations, ensuring consistent energy supply throughout the year. Overall, Cafarnaum represents a highly favorable location for solar PV installations, with its consistent year-round production potential and manageable environmental challenges.

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

Ideally tilt fixed solar panels 11° North in Cafarnaum, Brazil

To maximize your solar PV system's energy output in Cafarnaum, Brazil (Lat/Long -11.8067, -41.384) 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 Cafarnaum, 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 Cafarnaum, 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
4° 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 Cafarnaum, 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 Cafarnaum, 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 Cafarnaum, Brazil

Topographical Features of Cafarnaum, Brazil

Cafarnaum is located in the interior of Bahia state, positioned within Brazil's semi-arid northeastern region known as the Caatinga. The terrain around this area is characterized by gently rolling hills and elevated plateaus that form part of the Brazilian Highlands. The landscape sits at a moderate elevation, typically ranging between 400 to 600 meters above sea level, creating a relatively stable foundation for development projects.

The topography consists primarily of undulating terrain with gradual slopes rather than steep inclines. This rolling countryside is punctuated by occasional mesa-like formations and low ridges that provide natural windbreaks. The soil composition includes weathered crystalline bedrock covered by shallow sedimentary deposits, creating a mix of rocky outcrops and sandy soils typical of the Caatinga biome.

Drainage patterns in the region are defined by seasonal watercourses that flow during the rainy season but often remain dry for extended periods. These intermittent streams have carved gentle valleys between the hills, creating a network of natural depressions and elevated areas. The overall gradient of the land tends to slope gradually toward the northeast, following the regional drainage toward the São Francisco River basin.

Optimal Areas for Large-Scale Solar Development

The elevated plateaus and mesa tops surrounding Cafarnaum represent the most promising locations for extensive solar photovoltaic installations. These flat or gently sloping surfaces provide ideal conditions for panel arrays, offering stable ground conditions and minimal grading requirements. The higher elevations also benefit from consistent air circulation, which helps maintain optimal panel temperatures and reduces dust accumulation.

Areas with southern and southeastern exposures on the rolling hills would be particularly well-suited for solar development, as these orientations maximize exposure to the sun's path throughout the day. The moderate slopes in these areas, typically ranging from 2 to 8 degrees, can actually enhance solar collection efficiency while providing natural drainage for maintenance access roads.

The relatively sparse vegetation cover typical of the Caatinga landscape means that land clearing requirements would be minimal compared to forested regions. This factor, combined with the generally stable soil conditions and low population density, makes large tracts of land potentially available for development with reduced environmental and social impacts.

Transportation access represents another important consideration, with areas closer to existing roads and transmission infrastructure offering practical advantages. The flatter terrain between hill formations could accommodate the necessary electrical infrastructure and maintenance facilities while keeping the actual solar arrays positioned on the optimal elevated sites nearby.
