Passo de Camaragibe, Brazil represents an excellent location for year-round solar energy generation, benefiting from its tropical position where consistent sunlight is available throughout most of the year. The seasonal variations in this region are typically characterized by wet and dry periods rather than the traditional temperature-based seasons found in temperate climates.
Solar Energy Production Performance
The solar energy output at this location shows strong performance across all seasons, with spring delivering the highest production at 7.27 kWh per day per kW of installed solar capacity. Summer follows closely with 7.02 kWh/day, while autumn generates 6.10 kWh/day and winter produces 5.28 kWh/day per kW installed.
Spring and summer represent the ideal times for solar generation at this location, producing approximately 38% more energy than the winter months. Even during the lowest production period in winter, the output remains substantial, making this location viable for consistent year-round solar energy generation.
Optimal Panel Configuration
For maximum year-round energy production from a fixed solar panel installation at Passo de Camaragibe, panels should be tilted at 8 degrees toward the north. This angle has been calculated by analyzing daily solar elevation angles throughout the year and weighting them according to solar irradiance data to determine the optimal fixed position that maximizes total annual output.
Environmental and Weather Challenges
Several local factors could potentially impact solar energy production at this tropical Brazilian location:
- High humidity and frequent rainfall during wet seasons can reduce solar panel efficiency and create more frequent cleaning requirements
- Salt air corrosion from proximity to coastal areas may affect panel frames and mounting systems over time
- Intense tropical heat can reduce panel efficiency, as photovoltaic cells perform less effectively at very high temperatures
- Dust and debris accumulation from surrounding vegetation and occasional dust storms
Preventative Measures for Optimal Performance
To maximize solar energy production despite these challenges, several installation strategies should be implemented. Proper panel spacing and mounting systems that allow adequate air circulation will help manage heat buildup and maintain optimal operating temperatures.
Installing panels with anti-corrosive mounting hardware and frames specifically designed for coastal tropical environments will extend system lifespan. Regular cleaning schedules become particularly important in this climate, with automated cleaning systems or easy-access designs facilitating maintenance during humid periods.
Selecting solar panels with higher temperature coefficients and proven performance in tropical conditions will help maintain efficiency during peak heat periods. Additionally, incorporating adequate drainage and ensuring mounting systems can handle heavy rainfall will protect the installation during wet seasons.
Despite these considerations, the consistently high solar output throughout the year makes Passo de Camaragibe an attractive location for solar energy investment, with proper installation and maintenance practices ensuring optimal long-term performance.

Solar output per kW of installed solar PV by season in Passo De Camaragibe
Seasonal solar PV output for Latitude: -9.2971, Longitude: -35.4276 (Passo De Camaragibe, Brazil), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
 
Ideally tilt fixed solar panels 8° North in Passo De Camaragibe, Brazil
To maximize your solar PV system's energy output in Passo De Camaragibe, Brazil (Lat/Long -9.2971, -35.4276) throughout the year, you should tilt your panels at an angle of 8° 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 Passo De Camaragibe, 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 Passo De Camaragibe, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 8° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 6° South in Summer | 15° North in Autumn | 25° North in Winter | 3° 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.

Topography for solar PV around Passo De Camaragibe, Brazil
Regional Topography and Landscape
The area around Passo de Camaragibe sits within the coastal plains of Alagoas state in northeastern Brazil, characterized by relatively flat to gently undulating terrain. This region forms part of the broader Atlantic coastal lowlands, where elevation changes are generally modest and the landscape transitions gradually from inland areas toward the ocean. The topography consists primarily of sedimentary formations that have been shaped by coastal processes over geological time, creating a terrain that is neither mountainous nor deeply dissected by valleys. The immediate vicinity features a mix of agricultural lands, scattered vegetation, and areas of natural coastal plain ecosystem. The terrain slopes very gently toward the Atlantic Ocean, which lies to the east, creating natural drainage patterns that flow in that direction. Small streams and seasonal watercourses meander through the landscape, but these waterways are typically shallow and do not create significant topographical barriers or steep-sided valleys.Terrain Characteristics for Solar Development
The relatively flat nature of the terrain around Passo de Camaragibe presents favorable conditions for large-scale solar photovoltaic installations. The gentle slopes and minimal elevation changes reduce the complexity and cost of site preparation, grading, and infrastructure development that would be required for solar farms. The sedimentary geology underlying the region generally provides stable foundation conditions suitable for mounting large arrays of solar panels. Areas to the west and southwest of Passo de Camaragibe appear particularly well-suited for solar development due to their combination of flat topography and distance from dense settlement areas. These locations offer expansive tracts of land with minimal topographical constraints, allowing for efficient panel layout and optimal spacing between rows of solar arrays. The terrain in these areas experiences minimal shading from natural features, as the landscape lacks significant hills, ridges, or dense forest cover that could interfere with solar collection.Optimal Site Selection Considerations
The most promising areas for large-scale solar installations would be the inland agricultural zones where the terrain remains consistently flat and open. These locations benefit from stable ground conditions and existing access to transportation networks, which would facilitate construction and maintenance operations. The coastal plain environment means that dramatic elevation changes are uncommon, reducing concerns about complex grading requirements or unstable slopes. Areas further inland, particularly to the northwest of Passo de Camaragibe, offer additional advantages for solar development. The topography in these zones remains favorable while providing greater distance from coastal influences such as salt air, which can affect equipment longevity. The terrain continues to be characterized by gentle undulations rather than steep grades, making it possible to develop large, contiguous solar installations without significant modification to the natural landscape.Brazil solar PV Stats as a country
Brazil ranks 13th in the world for cumulative solar PV capacity, with 13,708 total MW's of solar PV installed. This means that 2.50% of Brazil's total energy as a country comes from solar PV (that's 31st in the world). Each year Brazil is generating 64 Watts from solar PV per capita (Brazil ranks 47th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Brazil?
