Located in the tropics, this coastal municipality benefits from consistent sunlight patterns that make it a favorable location for photovoltaic installations. The seasonal solar energy production in Camamu demonstrates good year-round potential. During summer, solar panels can generate approximately 5.68 kWh per day for each kilowatt installed. Autumn sees a slight increase to 5.95 kWh per day, making it one of the most productive seasons. Winter experiences the lowest output at 4.67 kWh per day, but this figure remains substantial compared to many other global locations. Spring rebounds to 5.90 kWh per day, nearly matching autumn's productivity.

Optimal Installation Angle

For fixed panel installations in Camamu, Bahia, the ideal tilt angle to maximize year-round solar production is 13 degrees facing North. This specific angle has been calculated to optimize energy capture throughout the year, accounting for the earth's elliptical orbit and the location's position in the southern hemisphere.

Seasonal Considerations

The data indicates that autumn and spring are the most productive seasons for solar generation in Camamu, Bahia, with nearly identical output levels. Summer follows closely behind, while winter shows a moderate decrease but still maintains respectable production levels. This relatively consistent seasonal pattern is advantageous for year-round energy planning.

Environmental and Weather Factors

Several environmental factors could potentially affect solar production in Camamu. The region's tropical climate brings a distinct wet season, typically from April to July, which can reduce solar efficiency through increased cloud cover and rainfall. Additionally, the coastal location may expose solar installations to salt air corrosion and occasional tropical storms.

Preventative Measures

To maximize energy production despite these challenges, several preventative measures can be implemented:

• Install corrosion-resistant mounting hardware and solar panel frames to withstand salt air exposure
• Use marine-grade protective coatings on electrical components
• Implement robust drainage systems to manage heavy rainfall
• Design mounting structures to withstand tropical storm wind loads
• Schedule more frequent cleaning during dry seasons to remove salt deposits and maximize efficiency

Regular maintenance becomes particularly important in this tropical coastal environment. With these considerations addressed, Camamu's consistent sunlight throughout the year makes it a viable location for solar energy production, with only moderate seasonal variations affecting output.

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

Ideally tilt fixed solar panels 13° North in Camamu, Brazil

To maximize your solar PV system's energy output in Camamu, Brazil (Lat/Long -14.0181, -39.224) 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 Camamu, 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 Camamu, 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
1° South in Summer	20° North in Autumn	30° 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.

Calculate solar panel row spacing in Camamu, 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 Camamu, 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 Camamu, Brazil

The topography around Camamu, Brazil presents a diverse and complex landscape characterized by coastal lowlands that gradually rise into rolling hills and plateaus as one moves inland. Situated in the state of Bahia, Camamu lies within the Atlantic coastal region where the terrain features a mixture of flat coastal plains, mangrove swamps, and river valleys that transition into more elevated terrain further from the ocean.

Coastal Features

The immediate coastal zone around Camamu consists of low-lying plains interspersed with mangrove forests and estuarine systems. The Camamu Bay, a significant geographical feature, creates a natural harbor area surrounded by these lowlands. These coastal areas have minimal elevation, typically ranging from sea level to about 20 meters above sea level, with very gradual slopes.

Inland Topography

Moving inland from the coast, the landscape begins to change noticeably. The flat coastal plains give way to gently rolling hills with increasing elevation. This transition zone features undulating terrain with elevations typically ranging between 50 to 200 meters. Further inland, the topography becomes more pronounced with steeper hills and occasional plateaus, some reaching elevations of 300 to 500 meters above sea level. The region also contains numerous river valleys that cut through the landscape, creating natural drainage systems that flow toward the Atlantic Ocean. These rivers, including the Camamu River, have formed valleys with varying widths and depths, contributing to the topographical diversity of the area.

Vegetation and Land Cover

The natural vegetation around Camamu reflects the region's position within the Atlantic Forest biome, though much of the original forest has been modified by human activities. Coastal areas feature mangroves and restinga (coastal tropical and subtropical moist broadleaf forest), while inland areas transition to more diverse forest types on the hillier terrain. Agricultural land, particularly cacao plantations and other crops, occupies significant portions of the landscape, especially in the flatter areas and gentler slopes.

Solar PV Potential Areas

For large-scale solar photovoltaic installations, several areas near Camamu offer promising conditions based on topographical considerations: The inland plateaus and gently sloping hills located 10-30 kilometers from the coast present some of the most suitable terrain for solar development. These areas benefit from relatively flat or moderately sloping land that receives consistent solar exposure throughout the day. The elevated nature of these sites also means they typically experience less fog and coastal cloud cover than locations directly on the shoreline. Specifically, the cleared agricultural lands on the eastern-facing slopes of hills west of Camamu offer good potential. These locations combine favorable orientation toward morning sunlight with sufficient elevation to avoid coastal weather effects. The terrain in these areas is stable, with minimal risk of flooding or erosion compared to lowland sites. Areas to the north and northwest of Camamu, where the landscape rises more consistently, also present opportunities for solar development. These locations feature larger contiguous areas of suitable terrain that could accommodate substantial installations without requiring extensive grading or modification of the natural topography. It's worth noting that while the coastal plains might initially seem appealing due to their flatness, these areas are less ideal due to higher humidity, potential for flooding, and valuable agricultural use. The optimal balance between accessibility and favorable conditions tends to occur in the transition zones between the coastal lowlands and the more pronounced hill country further inland.
